Media bashing Boeing again.777 200 wheel came off

The media are bashing Boeing once again.

A united airlines aircraft was departing San Francisco airport, it lifted off although one wheel fell off.

The media here are bashing Boeing.

I find it hard to believe it’s Boeings fault, as the undercarriage is probably supplied by an external supplier, as well as associated components.

Who knows if the ground crew tensioned the wheel nuts properly.

How many times have the tyres been replaced and who was the contractor, was it done to specs.

These are questions the media do not ask.

Funny you bring up that issue with Boing when the 737 max is in the news again.

Boing has gone down hill since the bean counters took over running the company from the engineers years ago.

They deserve at least some of the 'bashing'.

It certainly does not look good for them when the wheels come off their planes.

Bolts seem to be an issue for these muppets if im honest.

Exactly. The left over parts from the airplane kit are a very real concern when working in 1:1 scale.

Who needs wheels anyway when planes fly! /sarc


It's not looking good for Boeing lately is it? Panels and windows popping out and now wheels falling off, lets not forget the 737 MCAS system fiasco.

Yeah this is why the only times I have flown were with my dad in his old piper super cub. Well and one time his army friend took me for a helicopter ride. Mistake!!!!! Gotta trust the maintenance and the pilot.

I used to build customized bicycles and even built a couple of motorized kits from China. The old "Whizzer" motorized bike design went over to China and the hardware in their kits is complete crap. I had to replace all the important bolts with hardened steel bolts made in the U.S.A. Also, the drive chains were crap too, I replaced them with #41 roller chain made in the U.S.A.

My only point is that China makes crappy hardware like bolts and they will take a good design and make it non-functional with cheaply produced parts. This could be the case with Boeing as well as any of the big manufacturers, they use cheap Chinese parts that fail under stress.

Thats what happens when shareholders profit is the be all and end all.

But who can forget when Airbus demonstrated a low pass at an airshow?



en.m.wikipedia.org...

Until today I had thought that was a fly-by-wire fail. Viral videos make you dumb.

Ripping on Airbus aside. UNITED GROUND MAINTENANCE CREW.

It reminds me of Continental Express 2574. Where the leading edge fell off after an ice boot swap... because they didn't attach one half of the horizontal stabilizer. It was a shift change, assumed work done, and a supervisor signing off without checking.

This one:

That was Aibus' attempt at building a lawnmower not an aircraft!

Take a look at a picture of a 777 taking off or landing some time. Each main landing gear strut has 6 tires on it (2 rows of 3). The nose gear strut has 2 tires, side by side. They're designed that way so that you can lose a tire on any strut and still execute a safe landing or take-off.

As a pilot, you don't want to do that, but the redundancy is designed in so that a flat or missing tire doesn't automatically destroy the airplane.

a reply to: Boomer1947

Yeah, I know.
A 777 having 14 tires, maybe United Airlines went for part worns on the cheap instead of going to a main dealer!!!

a reply to: Degradation33

The Airbus was a pilot training / lack of understanding of control system issue.

The pilot tried to go around on the landing without informing the flight automation. Airbus is designed to override pilot inputs to protect the aircraft. On that case, it plowed the end of the runway.

The deicing boot was a procedure failure because a pilot helped.

The deicing boots were scheduled to be replaced but it was decided to only do one side that day by maintenance. The pilot helped by removing the screws on the boot that was not going to be replaced. The next shift that reinstalled the boot did not know the pilot had removed the other sides screws. Not a shift change fault as much as a improper help that did not follow paperwork fault.

a reply to: BeyondKnowledge3

Yeah I realized that shortly after posting.

I went back and fixed it. I blame internet videos.

But is it really a "Boeing" issue and not a "United Airlines" issue?

Did the wheel fall off due to a faulty design or did someone make a mistake during wheel maintenance?

Lot of jumping going on.

Wheels falling off of aircraft isn't the fault of Boeing. They shouldn't be blamed for this particular incident.

It gets worse though. Earlier today, a United 737 ran into the grass after landing in Houston/Bush. No word on the cause.

a reply to: LogicalGraphitti

They turned off the runway at 25 knots with rain and water on the runway and taxiway. Pretty sure that’s human error.

a reply to: BeyondKnowledge3

The preliminary report appears to show that it may have been a parts failure specific to this aircraft. The rudder input torque tube, upper and lower bearings, and rollout guidance servo were removed and replaced. The new parts were flown on the exact same profile as the test flight that found the problem, with no issues. The aircraft was configured with the SVO-730 rollout guidance servo disabled, to configure the aircraft from CAT-IIIB to CAT-IIIA, but the servo was still physically connected to the torque tube. The servo was taken to Collins and cold soaked, where it was found that the torque was beyond design limits.

a reply to: andy06shake

It's a 22 year old plane. How exactly is it on Boeing other than people that don't know crap about aviation screaming "BOEING" repeatedly?

a reply to: Cavemannick

The plane was delivered new January 2002 to United. It's had tons of tire replacements in that time, this was just the latest one. Either something broke on the truck it was installed on, or a mechanic screwed up and it wasn't fully torqued.
