Hello all!
First off I would like to say THANK YOU to every single individual who has made a donation or a kind comment on the YT videos. I never expected anything like this to happen, only to tell my story in hopes to educate/help individuals looking to take the same route I am while having fun with Juan! The support I have received has blown my mind. I am truly speechless. I have read every comment and seen every donation and no words can express my gratitude. I am scheduled to attend Bakers in July. From the bottom of my heart thank you thank you thank you! -Sincerely Jordan
The smile on your face is priceless! I'm so happy humanity did the right thing for once 😂
You couldn't pick a better time to come into the industry, especially on the commercial side of aviation. You'll hit the $100k per year mark in short order. Lots of us 'old' timers' are heading towards retirement and the rocking chairs. Good luck with school and we'll see you soon!
You must now launch your own yootoob channel.
There is no other option for you.
you can do it!
Jordan, at 75 and former A&P for 'recips' it is so wonderful to see young people learning how to diagnose, fix, design and build with your own talents. I'd wish you luck, but with your abilities and drive you're already succeeding. Thank you, Jordan, for staying true to your dreams.
She's marriage material.
@@dryan8377 yes she is. 😊
I got my license from Charlie McAllister. His license was from Orville Wright. I no longer fly due to heath issues, but enjoy your channel. I too had prostrate cancer. Had it removed but no further issues. I’ve rebuilt some Champs and TaylorCrafts. Flew the old stuff, Champs, tri pacer, Taylorcraft, 172 was my jump plane. Charlie had a 310 as his dual engine trainer. Based out of Yakima Washington. Cub Crafters is now in the building I flew out of.
Love your story sir. Thank You.
Wow. Orville Wright. That’s amazing. Makes you realize how far we’ve come in just over 100 years of aviation.
Same here. My instructor soloed in 1926 at age 14 with 4:15 dual received in a Hisso powered Standard. Charlie was his instructor.
@@tennesseered586 Charlie opened his school in 1924. I joined him in 1970 so he had been teaching for 50 years
My Gramps had his from Orville also. I am 60, have not piloted since 1999-2000.
By popular demand...here ya go! Let's send Jordan to A&P school!!! gofund.me/5dc576d5
@@kristyskirt9015 If you can do it, she will complete it. Lead by example Captain
Six hours and the generous followers of JB have raised over $3,000 towards a goal of $2,500. BZ and all that jazz. I hope you enjoy Tennessee, Jordan, from Liz and Ginger in Australia.
Glad to contribute!
I came here to ask exactly this! So important to encourage young people to follow their dreams! Good luck Jordan
What a joy to see this happen so quickly.... Thanks Juan! if you get the chance, would you do another little video to let us know how she’s getting on? Cheers!
A great video. Being an ex-Navy machinist mate it does my heart good to see this young lady at work making general aviation a little safer.
MM's were the best drunks ever on liberty. Lol. Love you guys.
@@dryan8377 Thanks for the compliment. Being on a missile sub was even better because we had 30 days of R&R after patrol, and I drank a lot back in those days (1965-1970). I hardly touch the stuff these days.
Compression check can be so dangerous, good job taking all the precautions. A co-worker of mine was almost killed when a blade swung around and hit him square on the head.
Good to see the next generation of A&P mechanics taking the job seriously. So far so good with the inspection. Good luck.
I did the 18 months in school - only to graduate in the mid 80’s when the airline market crashed. Mechanics with years of experience were forced to go GA. There was no hope for us newbies. So I went and wrenched cars. Sucked after spending thousands for school and the rest. Not much use knowing the baseball stitch. At least I could use my new tools. I had a huge advantage on the old line car guys in that the electronics didn’t scare me like so many beginning in 1984.
Come on now... 300,000 subscribers and Jordan needs a few bucks to get her ticket? Let’s crowdfund it!
Lets do it baby!!!
Agreed!!!
Absolutely, Jordan is a sweetheart. Get her there!!😀
I'd be willing to put in money you know how
Does she have an Go Fund Me setup?
She has proven herself with the time she has invested in herself and career field, it’s a great investment for us. I’m in!
That was a great video showing compression test....I had received my A&P back in 1979 and went on to Parks College for Aircraft Maintenance Engineering. I then joined the Space Shuttle program working on ECLSS and ATCS systems and EMU/PLSS for 32 years till the end of the program. My last eight years before retirement, I worked Airbus A-380 program as the service engineer for ATA21 and ATA36 systems along with helping on B744 and B777 programs mainly for Emirates, Singapore and Malaysia Airlines. In my 40 years the now Raytheon Collins Aerospace was UTC Hamilton Standard, Hamilton Sundstrand, United Technologies Aerospace Systems (UTAS) and then Collins Aerospace. I took an early retirement Package shortly after Raytheon took over and COVID hit. Miss the people and work, but not all the traveling......Keep up the great work on the your TH-cam Channel.....
wow. impressive.
So poud of Jordan... Hope she gets all the help needed to complete this noble goal.
AMEN!
The Leak down test always makes everyone so nervous. If the numbers are too low its such a bummer!
When I worked as a A&P I had several large bore engines that failed the leak down test by blowing passed the rings. The engines would make rated power, run well, and the oil burn was within limits.
The owners would get so pissed when this happened. And I could see why..
Aviation can/ is so expensive.
I'm a C172 owner with a very high time engine. It doesn't leak and runs good but a big expense is coming soon.
Wishing all the best for Jordan. I had to leave the A&P trade because the pay was so low I had to make a living and working on GA stuff didn't make ends meet.
“Spark plug cleaning“ and “action“ - two things you don’t usually hear in the same sentence - I’m on the edge of my seat, Juan! :)
The 310 is such a beautiful airplane. Ageless design, IMHO.
Thanks for the education - very interesting. Great to see a young lady on her way to becoming an A&P. :)
Edit: as others have said, I'd kick a few $$$ into helping with her expenses.
10k to get an A&P, 100 k to get a degree in gender studies that the crazies want to write off on the girl who got the A&P!
@@wycombewanderer6649 That's the sad reality of today! 😂
i have no idea what aviation medals are available if any, but juan, peta (mentour pilot) and kelsey (74 gear) all deserve some recognition for "services to aviation". i hated flying, but these guys have transformed me into a relaxed flyer. each bringing a slightly different take on all things aviation. i would love to see all 3, sitting around a table with a few beers just shooting the breeze and chatting aviation for a few hours. i know juan and peta manage to meet up, and getting all 3 in the same room could be a challenge given that pilots are at different places all over the globe on any day, but i would pay good money to watch THAT show.
Same for me. I used to "help fly the plane" all the way from SFO to MEL. Talk about a back seat driver. ;-) Thanks to Juan, I am relaxed enough to sleep most of the way.
This brings back memories of my first corporate flying job in 1969. Our company had an "I" model 310 and 411. I had an A&P license although I was working as a pilot. I got to help a little on maintenance but because I was the "new guy," most of my labor was cleaning and waxing. I didn't mind because I was thrilled to be flying. That A&P training was very useful for understanding new systems and analyzing any problems during 31 years of corporate flying.
Our local community college has an A&P school that feeds a large AMR maintenance base here in RFD. These are good jobs in high demand.
‘’Props’’ to Jordan for choosing this career path! I wanted to go to Embry Riddle back in ‘76 but it wasn’t to be. Love Harvey Juan. It is a beautiful bird! Those Continentals were made right here in Mobile. Glad to see them holding up so well. Stay safe!
Interesting! What you're calling a "differential compression check" is what the automotive world calls a "leak-down test". For car folks, a compression test uses the starter to crank the engine over, and the pressure in the cylinder is measured. The leak-down is often a next step if the compression numbers come out low.
You beat me to the same comment.
Well I can see why they do it this way since a spinning propeller is always a hazard.
Everyone in aviation also calls it a leak-down test...
We called it a "cylinder differential pressure" check at our airport. You're checking the cylinders ability to hold a certain amount of pressure vs a compression test which is a check of the cylinders ability to produce pressure.
I used Bakers for all of my written exam prep and testing. They are top notch! They'll get Jordan through with no troubles.
I chuckled a bit when you were running through your start up checklist. It reminded me of my father who would sometimes jump in the car with us kids and before starting the car he would run through the start checklist for his beloved DC-3 from his prodigious memory. Sometimes he would change it to the Mitchell bomber. Lol. He was a character, alway amusing us. Hard to believe he’s been gone from 20 years already. Keep up the great vids Juan!
That's a great story, Doug! Sounds like your dad was a great man. God bless him! Thanks for sharing!!👍
Wow. Mine didn't do that but he flew both the C47/DC3 and the B25 as well!
@@dryan8377 RCAF or USAF? Dad had a knack for being able to memorize stuff. He would recite Robert Service poems like the Cremation of Sam Magee from memory. One time we were looking at his RCMP class photo taken on completion of training in 1948, nearly 50 years later and he rattled off all their names. How the heck can you do that I asked. He said I was the shortest guy in the squad and was always front row center as he was in the pic. Every morning the Staff zSgy stood directly in front of me and bellowed all the names into my face. Guess it kinda stuck. Ll
@@dougtarbet6193 USAF. I remember the day he got his papers releasing him from Reserve duty around 1970 or so at the kitchen table. He told stories over and over from his time flying.
@@dryan8377 well we sure have that in common, hearing Dad tell his flying stories. He was retired from the RCAF on his 45th birthday in 1973 which was then the mandatory retirement age for pilots at rank of Captain. Now the retirement age is 55.
Come on Juan, let’s roll, so many subscribers want her dream to come true. Crowdfunding is what we all want for this young
Beautiful lady.
Yes!! gofund.me/5dc576d5
OK, guys I just donated towards her dream come true, now it’s your turn to help her follow her pursuit.
Great to see the next generation of A&Ps getting the skills and experience to keep aviation chugging along!
I was lucky in my birth date. I got my A&P going to Spartan in 1964-65, total tuition $1600. Of course, my only real experience was as an Air Force weapons mechanic, so Jordan is already about ten times the mechanic I was on my first job, when I was confronted with the responsibilities of maintaining R-1830s and R-2800s. Crazy times then. Let's get Jordan's Go Fund Me going here, seriously.
See the pinned comment for a link to Jordan's GFM.
@@lizj5740 Done. Thank you.
After watching Sky King's 310 as a kid, it's always been one of my fav's! Good luck! Rock on Harvey 😜
My real name is Harvey, I’m 70 and always got kidded about “the rabbit”. Your plane reminds me of my kid addiction of watching every show of Sky King. I personally graduated up to a C-182 std., all analogue with a rarely working tube type DME, but learned in an old 152 for $4 bucks an hour wet!, and $3 bucks for the part-time, evening only CFI. I am also proud I soloed after the minimum permitted 4 hours (that includes taxi time back to the runway after dropping off the instructor...lol. Congrats, your channel has come a long way. Keep up the great work!
I have many fond memories of the old family 310C N1771H; I flew it hundreds of hours out of an 1800’ strip at 340’ elevation. Often traveled to our ranch east of the Cascades where we had a 3000’ dirt strip. That old bird never let us down. We moved up to a G model and the guy from Missouri that bought 71H destroyed it during a single engine landing
except for the music, this was one of your best vids. Jordon working on the plane was a real bonus.
I flew a C310H ('63) for about 600 hours. Started out same color as Harvey. We repainted it blue, silver & white. Great airplane! It's still in the registry! I was going to become a commercial pilot but went ATC for 20 years after I got my Instrument Multi & Commercial. Got to go home after work every day instead of the motel scene.
Juan so good to see how meticulously you take care of your planes & so good to see the next generation taking the initiative to be a positive contributor to society!! Keep it going Jordan you got a great career ahead for you!!!
What a great older airplane!! I've seen some 30 years newer and not looking that nice! Congrats Juan!! 8) --gary
Love your 1959 C-310. I have many hours in those as we had them in the Army Reserve program. U-3A (1959) and the U-3B (1960). Loved the cowling on the 1959 as to leaning the fuel flow at night, you could see the exhaust stacks turn a bright cherry red when too lean and then you just backed off till they turned a little darker. We had no auto pilot so all was hand flown all the time. Once flew from TEB down to FTW and on to ELP and LAX area. 4 day trip. Left it in an IRAN program in CA. These were all AF hand-me-downs to the Army. Go figure, we gave the AF all our Caribous in 1968. Not an even trade!
Great video. Good to see the young lady's passion for A&P. They are so important to aviation.
It's always good to see young people wanting to further their education in a field that they already work in. It's a much better choice than some of the ones that get a useless degree with very little chance of ever using it. I'm in.
As the work places are overwhelmed by people working at home in their jammies, the broad spectrum of trades is suffering a steep decline in workers who think that getting dirty hands is beneath their entitled selves. A great deal of the housing shortage is caused by people, ignoring the wage points out there, who prefer to work with a laptop instead of a saw. Same with autos - the mechanics who actually fixed them have turned into fancy-uniformed technicians who only know how to take out a unit and replace it with a new one. Actual tear down and repair is gone with the good ol' boys in dirty jeans.
The first piston twin I ever saw up close was a 1969 310.
I thought it was the most beautiful airplane ever.
I still do. ♥️
Good to see young people interested in being an A & P. I enjoyed my training and testing back in the day. All the best to this young lady.
(might I suggest a tighter grip on that prop when under pressure.)
I am glad to see someone that is being treated good by aviation. I wasn't so lucky. After 20 years and a lot of traveling in the civilian world, I am at this point in transitional housing through the VA. Without them I would be on the street. There is a lot to be said for my last job in aviation, little of it good.
On another note, it helps that you are a conscientious owner. My short time in general aviation was with a bunch of lease back 172'2 that were used for training. Your 310 looks like it was well kept before you got it. Best of luck with it. And best of luck to the new A&P.
The previous owner aged out and sold it to Juan. I guess it sux to have to stop flying.
Fun to see you in the mechanics world, that old continental 470 still has good compression numbers,Good luck to Jordan on her A&P testing,I am mentoring a 6 pack of students from the SLC Airport school, here at a 135 operator.Glad to see more women coming into the field.
She definitely needs to get her A&P license a lot of us A&P mechanics will be retiring in the near future and opening up more airline jobs.
Thanks Juan, for an old 310 driver, the start-up and taxi was an ASMR moment.
It really is fantastic how so many young women are choosing to get involved in all aspects of the transport industry. I was at train driver until I retired a couple of years ago. When I started in 2003 there were only two women drivers at my depot out of nearly two hundred drivers. When I left it was up to around 20. Train driving is one of the very few professions where a woman is automatically, and quite rightly, paid the same as a man doing the same job. All professions should be like that without question. In this video, Jordan clearly enjoys her job. Her enthusiasm and her knowledge will carry her far - I wish her all the very best and hope she achieves everything she wants.
Every video Juan does just affirms the fact that I am not cut out for aviation. But I enjoy watching. I’d be like eh mixture good enough.
Juan, I did my A&P School at City College of San Francisco. 2 1/2 years. Normally it would take 2 years with the 8 courses, but my first and last semesters, I only took one course. Took my Oral and Practical, then my Written. You can take the O&P before written if you go to a school. I had my instructors give my O&P they were DME's also. When you take Written test, the first license you take, you will need to do 2 test, the General and either Airframe or powerplant. On the oral for first test, you will have to do a Weight and balance problem. Then after you get those written passed you can take the other one. Still have my A&P but not in the aviation area anymore.
Good luck to Jordan on her A&P rating. I'm sure you've been a good mentor to her, Juan.
She's mentouring me!! She knows her way around Harvey!
I'm completely uninterested in flying skills, but I feel very compelled to listen to Blancolirio when he does his annual inspection.
Jordan is awesome!!! Good luck. I am so happy she borescopes the cylinder to look at the exhaust valves...so many A&P freak out with low compressions that they recommend pulling the jugs! Ridiculous....some valves can be lapped and a tear down can be avoided. Good luck Jordan!!
So glad you could help her with the money for school. Thats just awesome!
Class looking machine!Still looks fresh. From an era of iconic aircraft design.
I went to Baker in TN for my A&P practical and oral exams. It worked for me. I’m sure Jordan will do great
Jordan needs a go fund me for her schooling. You should get that going Juan.
He has. See the pinned comment for the link.
Go Jordan, A+P at Bakers is a sinch! They were just great! You have plenty of practical experience already. The questions are on the internet, Study them up, you will be fine! I combined my A+P at Bakers with a trip to OSH, all the way from Australia, had a blast! When I do Comp checks, I always do them through the bottom plug holes. I have had too many instances where the carbon has dislodged and fallen into the valve seats and given a crap reading. Rocker covers off, wacking valves, re-running the engine. For the little extra effort, comp check in the bottom hole, it can save a heap of grief.
Great point!
As a retired auto mechanic in our world the test performed here was a cylinder leak down test . Not a compression test par se. A compression test measures the amount of pressure generated in a cylinder at cranking speed . And not a cylinder's ability to hold pressure . Which is what a leak down test is for . When I began my career in 1964 we also did compression tests dry and wet ( with oil ) . Which was a quick check of ring wear . We had 4 places pressure loss could go to . Compared to your 3 in an air cooled engine . Always good to see new blood learning actual skill . Unlike the "woke " bullcrap . Harvey is one sweet bird . Thanks for sharing .
Wish I had more piston experience, but jets and turbo props were 99.99% of my work for 47 years. As our older mechanics said there is nothing like the smell of hot round motor blood in the morning!
So, Mr Brown, you own that? Wow, sweet, and I have no doubt it lives in a hangar. Once in my 20s, I visited a private hangar and a guy had a beautiful C182. I was so jealous, but I was told the owner was an AA pilot. I thought, oh well that explains it. I thought if I could become a pilot with a major, someday something like that would be affordable for me. Well, I retired from a major with 27 years, but the money was great only for the last handful of them. So I am flying X-Plane 11 and watching TH-cam videos of others, living vicariously. Awesome ride there, sir.
Magnificent. One of the most beautiful aircraft ever built . .. .
Fantastic video JB! As an old (and possibly slightly jaded) engineer I must say it's nice to see a young person who so obviously is learning well and applying their skills so competently. Without good spanner twirlers, aviation is missing a major link in the chain and us old soaks need to impart our knowledge to the next generation as well as all of the new information and technology available from modern education so that these technicians and engineers can grow and improve on what we know.
Also, isn't Harvey such an absolute charmer? What a cracking old bird!
@ 5:06 i was expecting Jordan to say “ Back to work” as she raised her fist. Good on you Jordan. Im impressed to see you break the male stereotype of an A&P mechanic. Good luck with your studies.
As an A&P myself I appreciate pilots like yourself
My father spent 50 years working as an A&P mechanic. He started with Pan Am and ended with FedEx. Always nice to see videos showing the hard work these mechanics perform on a daily basis.
Nice explanation of route to A&P AND process to complete annual inspection! In addition, machines do not care about the sex of the operator, only about their experience and education!
Good for you Jordan, good luck with your endeavor. Also a good sport for joining in on the video.
Jordan, Go take your tests! Bakers will help you get through the writtens, (it's not just one!) and then they teach you exactly how to do the tasks necessary for the practical exam. It sounds like you have some supporters!
Getting my A&P was the most intensive studying I ever did. I found the written portion harder than getting my commercial and my ratings. I went to King School of Aeronautics in Nashville for the prep and testing.
Since you've acquired Harvey, they'll be calling you Sky King. It's sounding good & looking good. Glad that you kept some of the original gages & didn't flat screen it all out. Yep, it's comin down out there. Time to stay in the hanger. Best wishes for Jordyn to get it passed. Great informative video. Always learning from your videos.
Very welcome Juan.
I learnedmore about basic internal piston checks for aircraft engines, from this geat, pleasantly presented, video. Than anyother!
I’ve always thought of that as a cylinder leak down test which will tell a greater story than a cranking psi indication. Nice to see a well-guided procedure.
That’s all this is is a cylinder leak down test. The worth of it is increased when the test is done from day one of a new engine, and the leak percentage is monitored over the life of the engine. Really helps when diagnosing a drag race car when the et or mph seems off before you start chasing the tune or chassis.
@@GNX157 Actually... its not leak down. It's a aviation differential compression test...Its done under pressure at 80 psi... More than likely a "Master orifice" is involved..😊
@@techsolutions8237 What he’s doing is the same thing as a cylinder leak down, except in the automotive realm, we measure the leakage and describe it as a percentage, whereas he’s showing two different pressures, but it’s essentially the same thing. He’s looking for leakage in the various areas of the engine. Valves, rings, gaskets etc.
@@GNX157 Its not the same thing... It's a Aviation compression test. Do some research first.
We are talking about aviation maintenance, not automotive realm.
@@techsolutions8237 A 4 stroke engine doesn't care where it is used. Aviation and automotive use slightly different procedures and different terminology, but the basics of a Leakdown/Differential compression test are the same, only a few details are different.
Awesome plane and best of luck to Jordan.
As a AI for 43 years and a A&P for 55 years and working on U3A's in 1967, You have a very good helper there, Aviation is FUN. We need more younger kids to get interested in Aviation. You can tell when you are getting old, all my airplanes I worked on in the Air Force are in museums now
That school is just down the road from me. When she gets here she needs to visit Snow White drive in and Painturo's Pizza two of the best places in Lebanon.
Some of the best a&p mechanics I’ve ever worked with were female. Good luck to her. 15 year a&p/veteran
It’s amazing how much it takes to earn an A&P. I’ve had mine for 30+ years. I went to the Northrop University A&P school. You’d think it was soo long ago. Nope!
Harvey is awesome. I had the chance to see Harvey in person and see Juan prepare him for a flight from Utah to home. Great plane and in good hands with Juan.
I spent my first 4 years flying 134 IFR in a Cessna 310Q model. I loved that airplane. Flew Bank Paper ( canceled checks). I got really good at Instrument flying on that job. Two KX-170 B's with vor/ glide slopes, Bendix ADF. The boss got around to installing a DME. I loved flying the 310.
I am so excited to see this series in full
Awesome video Juan. Beautiful 310. Cheers.
Another informative video, Juan. That is a beautiful vintage aircraft. Glad you had the opportunity to buy it!
It's always nice to have a look behind the curtain. Thanks, Juan and Jordan.
Hi Juan, I currently have a son finishing his second year at Vincennes University here in Indiana getting his A&P, he’ll be going on to Purdue University to get his bachelors and then out into the workforce. He’s wanting to work on the engines of the jumbo jets.
Very cool, man. Thank you for posting! Thank you, BTW, for keeping Harvey in the air.
Great great video. Thank you for sharing Jordan‘s story
How is it that when I see your vids my excitement level goes up. And how is it one guy can be so cool!!!’
Wait and balance lol. I love it.
This is great Juan. Thanks so much for doing these. I turned some avgas into noise yesterday and this makes my day.
I've got 1 more for you. Cyl furthest from the oil pump.
Cyl depth gauge
Piston at 1/2 stroke
Move prop back and forth and record loss of movement with prop angle degree tool.
Can save crank cases.
Another great video. Good luck to Jordan!
Thank you for the video. Good luck to the young lady with her endeavors.
Good job, very clear and well produced. I mean, I have done plenty of compression checks, but I still enjoy watching how someone explains it all. Lovely plane.
Thanks for organizing the fundraiser. Let’s get this girl some support! Awesome stuff Juan. Best of luck to you Jordan!
Thanks for another informative video!
You are a wealth of knowledge.
You are very kind to share it with the rest of us.
Thank you Juan.
You are a true gentleman and a scholar. Lol!
Hurry up Jordan and get that A&P. It's all about getting your union seniority started. Big "A" is hiring and we need you!
Awesome to see a young girl so in love with mechanics. Wish you well for the future Jordan.
Love the 310. Flew it once into Midway 15 years ago. What a great flight.
Excellent vlog Juan.
Look forward to the next ones.
Yeah me too.
Cool stuff Juan. I geek out on Annuals and am impressed by good Mechanics.
Very professional, They kind of work you can depend when you are at 10.000 ft !!!!. These engines look gorgeus ... MINT
Seeing you run ole Harvey reminds me so much of my old 310G (which I wish I still had). I love the singing of the props and even the squeaking from the glare shield brings back memories. Good luck with the annual.
You never know what Juan is going to post next! I love it
I always learn something Juan watching your channel. Thanks Hopefully a inexpensive annual. No major surprises.
When I did my practical it was a compression test on a beech 18 and mag timing then hydraulic with gear retract. The same week when I was licensed I got sent to help another mechanic change a chug on a 18 hauling freight in 20f degrees with sleet. As a new A&P does not mean a warm dry hanger. Trapped the engine.
