- In the Alaska Airlines maintenance hangars, a routine inspection uncovers a worrying problem in a brand new Boeing 737. The technicians need to rule out a hydraulic leak, which means putting the plane through a battery of tests.

if people just see Boeing they all get defendant and blame Boeing instantly without actually understanding, it is funny
Bro really made interesting and informative video for plane lovers. keep it up ❤
737 Max 👍
The hell is hydraulic fuel?!
In particular, aviation hydraulic systems are used to help control and manage equipment such as brakes, flaps, thrust reversers, flight controls, and of course, landing gear.
Leak on a brand new plane,could happen, but if the senior technician understands, for now plane its safe to fly, thanks.
Hydraulic fuel?
Fluid is incompressible. Hydraulic fluid is a fluid specifically designed to be able to stand up to high pressure(and thus high heat) to move things that are extremely heavy against high amounts of pressure(so control surfaces, flaps, spoilers, landing gear, etc, and against high winds in the air).
Shawn completely misses the point. Good job
cool
boeing❤
Next video please ❤
Fuel leak for a brand new plane!? Of course a Boeing
Little knowledge is a dangerous thing. And it wasn't a fuel leak. And the aircraft technician explained the reason. And common sense and a logical mind would have led you to conclude why the issue can occur on any airplane. You didn't, ergo…
Fun fact: hydraulic leak is NOT the same as a fuel leak 😮
Don’t quickly point fingers at something you don’t know enough about
Listen before you talk
Yeah, you clearly did not watch the video and just decided to make a blind uneducated comment. SMH….
Where is the other anouncer
Do we still have the 747 today
Yeah. I think for cargo Airlines tho
So many cargo operators still use 747
And Lufthansa operates passenger 747-400&747-8

The description says, "The technicians need to rule out a hydraulic leak…"
No, the evidence pointed to a leak, so they didn't need to determine whether there was a leak or not. They did need to determine the source of the hydraulic leak as that was not obvious. They couldn't find an obvious source, so they attributed the leak to the hardening of the rubber seals in the extremely cold Alaskan climate while non-operational. Sealing requires a seal to conform to the adjacent surfaces and the cold makes the seal temporarily harden and "set" to the shape of the adjacent surfaces. When the system is initially operated after a cold soak, a cold-set seal may move to a new position and be non-conformant if the shape of the surface is slightly different, which may allow a little hydraulic fluid to leak past the seal. The leak is self-healing, as pressurizing the system heats up the hydraulic fluid and components, which restores the flexibility and conformity of the seals.
P.S.: This type of leak is not due to shrinkage of the seal; the aluminum that the valves and actuators are made of shrinks more than the rubber when cooled. Nor is it due to the seal becoming brittle when cold as that implies that the leak occurs when the brittle seal breaks, but a broken seal is not likely to self-heal later.
@PeteP , thanks for your reply. Not only was this video reporting ignorant but also the replies other than yours so far.
People are just uneducated, just downright stupid thinking they have to have a say on every little thing that comes along when 90% of them have no clue what they're talking about.
You don’t know WTF you are talking about. I have been a commercial aircraft mechanic for over 30 years…I would have spent about 10 minutes dicking with this “leak” and then gone and watched TV on double time for the rest of the night. NOT a big deal. And I would have flown on this plane the next flight. Pfffft.
Hydraulic fuel leak….??? Why do i look at this internet bullshit
so the main problem has not been fixed lol
You can’t fix something that doesn’t exist
Proudly All Anti-Boeing
Do you understand why?
Which is why I won’t be flying them.
Funny…I have been working on 737’s for YEARS…this is NOT a big deal.
Just to illiterate its 3000 PSI of skydrol
Illiterate? Come on man!
firsy view and like hi smithsonian
