Boeing 737-800NG Landing Gear Testing

Hello,

Does anybody know how Boeing test the landing gear for the 737-800NG?

How do they make sure it can withstand impact, each time the wheels are needed?

Thank you very much.

Nikolai

Is this a generic question about landing gear (which I can probably answer, or can probably a few others here) or very specifically about the B738?

Well, I was wondering how is the landing gear for the Boeing 737-800 tested? Like, how much can it take before it snaps or collapses?

But if you could answer how landing gear's are tested, what they can withstand, and what Boeing does to make them safe - then that would be perfect!

Many Thanks,

Nikolai.

Not sure how boeing do it but on the Series of programs on the A380 they showed a gear leg test.

Basically put a leg on rams, spun up the wheels and fired the rams so the tyres hit the ground with a similar force to landing at more than max weight (cannot remember the figures but sense would say that they tested it beyond its capabilities)

Rainboe, stick to the topic, not personal abuse please, it's rude and unnecessary. If you want to banter with Nikolai, there's a perfectly good PM system for the purposes, allowing him to be appropriately rude back

If your aircraft didn't do this .... it wasn't a hard landing

On the subject of hard landings

This was another exaple of a hard landing at a Farnborough airshow a few years back.

YouTube - deHavilland DHC-5 Buffalo Crash

Luckily no one hurt but some big dents in egos.

I've had to delete several posts here. Any further personal abuse will result in a ban of whatever severity it seems to deserve. This is a professional forum chaps, act professionally.

Nikolai - unless anybody beats me to it, give me a few days to sharpen my pencil and I'll try and give you an introduction to undercarriage approvals as they are done.

Thank you Genghis - I appreciate that you have removed the offensive to Polish people post.

I would be very grateful to know how the gear is tested!
