Minor Emergency - Watch the Landing Gear Cycle

No issues landing

So, gear pins?

So, gear pins?

I wondered, but would they move like that?

 

[MikeD]

Gear pins wouldn’t allow the nose and main mount struts to move at all. They are solid through the entire linkage at the fold point.

What would this be? A landing gear control unit failure partway through retraction? Some sort of WoffW switch failure at a similar moment? Heavy farts from coach?

Could have been a hydraulic pump failure or break in the system somewhere dumping the pressure. If you watch it you see the body doors open and the gear moves and then the gear goes back down but the doors stayed open. They didn't cycle closed to much later and out of camera shot.

probably a stuck Fetzer valve

Probably a faulty proximity switch on some portion of the gear retraction logic, maybe the airplane didn't know the I/B gear door was open? @MikeD is right about gear pins, the whole point of their existence is to physically not let the gear move from a down and locked position when they're installed. The gear on the airplane in the video started to retract and stopped, newer airplanes are easier and harder to work on simultaneously.

PJP Jeff flies for Cathay now?

It's all ball bearings these days...
