I added this to my new playlist for the Arrow. I start my complex rating today. I will be adding more self-GoPro footage to this playlist as I go through the training. Thanks for the great video Greg.
WOW, this is by far the best video that I have seen explaining the Arrow's gear system. I'm a CFI just looking for videos to share with my students for their complex endorsements and this have just moved to the top of the list! THANK YOU!!!
You did not mention that the emergency system is designed to be idiot resistant. With the gear selector in the up position and the emergency gear switch in the normal mode the gear will drop below 87 kts. When studying the diagrams for the 1968 Arrow that I used to fly, it appeared that the gear would drop with the master switch off as well. I did test the low speed deployment (at a safe altitude) but never tried the master switch test. I don’t have access to the manual any more. I loved that plane. 140 kts @ 9 gallons per hour.
Dude, thank you so much for this excellent explanation. The Arrow POH says virtually nothing about the hydraulic system components beyond providing the diagram seen in the video. We are quizzed on the Arrow landing gear system at our Part 141 school during stage checks, but we’re given poor references from which to learn. One of our “sources” is just a few paragraph-long document written by one of our CFIs (I think? God knows who) in which they vaguely and imprecisely explain the system. This video was very clear and helpful
I have a 1977 Piper Arrow III. The landing gear was working just fine until the annual inspection. At annual when we tested the emergency down cycle, it worked just fine. We did it three times. After that we had problems with fully retracting the gear. The gear would go up but he hydraulic pump would go on and off every three or four seconds for about 1/2 second, maybe less. The hydraulic pump was going on intermittently. I figured it was a leak somewhere and looked all over for that leak. Could not fine one. The gear cycled down just fine and no hydraulic pump intermittent operation. My mechanic said it may be the pressure switch going bad. He also thought it may be the emergency down mechanism. He also said it might be the pump. I disagree on the pump because it has been in the plane for just a few hundred hours. The mechanic seems to be all over the place with his diagnosis. What do you think? Any suggestions?
@@CFIGreg It is highly likely the gear up check valve leaking or not seating. Your explanation is great. I pulled the pump and sent if off for overhaul. I don't believe the hydraulic fluid has been changed in the pat 40 years.
I have a 1977 Piper turbo arrow III. On two recent short flights I have noticed the gear unsafe light illuminate and it appears that the main gear are sagging into the airstream, but the pump is not activating to fully retract the wheels. Any ideas on the cause?
I’m not really sure what would cause that. I’m not an A&P so my knowledge level of the landing gear is tailored more towards teaching students a basic understanding of how the gear functions. I would do some research and maybe consult an A&P. I’d also like to know the answer, shoot me a message if you find out.
I have that similar issue right now on my Turbo Arrow III. While flying if I did a abrupt push over with the yoke that would be enough for the light to go out. We put it up on jacks and found out which main it was and when we pressed up on the right main the light went off. We have new switches on hand and will replace it at annual this month. Hopefully that's all it is is just a bad switch.
Great video!
Any chance you can look over the electrical schematic on this plane too???

Constant speed prop video coming soon?
About to become a CFI and this is going straight to my CFI Video list! Easy to understand thanks to your explanation :)

No problem, I’m glad it helped.

I would only be guessing, I’m not really sure what would cause that exactly

Awesome video! Succinct. Informative. Loved it.

No definitive answer yet, but the consensus is that it’s a problem with the pressure switch.
