It seems there's a sense of malaise falling over everything and everyone in the USA. People at large simply cannot be bothered to care about anything, including torque specs for freakin' AIRLINERS

Culture problem as we hire people of a generation who were not educated or engrained with responsibility they avoid doing the right thing and this happens.

I agree. We need way younger CEOs (and legislators!). This current crop is perfectly fine rushing QA to ship defective products as long as it lines their own pockets. In industries where failures won't directly kill people they actually plan the obsolescence to happen.

Leadership from a more environmentally-conscious and empathetic Gen Z would definitely have safer products that last longer.

Get this generationalist BS out of here. It isn't supported by the facts. Airline safety has improved with each generation. There were many more plane crashes in the 1970s-1980s when boomers were in their prime. Five times as many!

Heh, I remember back then when they said "Airplane crashes come in threes", while I don't think that's exactly true, the number of large fatal crashes was much higher.

Such a crappy aircraft - can we just get rid of these already?

Bolts can be loosened, or fail to be tightened on any aircraft. I suspect this may be a problem with people and/or procedure.

Since the aircraft with the incident was extremely new, it is pretty certain that the bolts have not been properly assembled at Boeing, so the problem is with their assembly procedures.

Kind of non-sequitur, but am I disconnected from reality if at this point I do not want to fly on a Boeing aircraft?

It is really the 737 - not sure what is going on with the MAX design team - but it ain't good

The 787 and 757 seem to have been stable platforms.

And that hull loss wasn't on account of a faulty design, assembly or process issues. Crew and passengers were unharmed after a collision with a firetruck crossing the runway while the aircraft was doing its take-off roll.

Exactly, as I understand all those occurrencies were due to people on the runway for one reason or another.

I am not familiar enough with that incident but I wonder how fast the plane was going and how close it was to actually being airborne, that seems like it must have been quite the impact but given that all crew survived there must be some factor that I'm missing. Blind luck either way.

two 10ths of a second later and it would have been an entirely different story. Ugh.

How were these not noticed in proper inspections? Is this the first time these planes have been inspected?

They generally don't disassemble the entire plane every time they get inspected...

Shouldn't the bolts be safety wired after being torqued?

IIRC every bolt's torque value needs to be logged any time it's (re)fastened. At least that's true for aircraft engine maintenance, not sure if it applies to the assembly process of the airframe, I'd sure hope so!

Man, if that's not automated how do they keep the numbers from being fudged? That's a lot of bolts, isn't it?

How is Airbus doing meanwhile? I didn't hear about any production quality issues in their aircraft.

> The A320neo family has had four ground fatalities and one hull loss accident as of November 2022. https://en.wikipedia.org/wiki/Airbus_A320neo_family A320neo is the direct competitor to the MAX. So yeah, they're doing pretty well.

i'm not sure are you being sarcastic, there were no fatalities on the airplane. but once motorcycle and another time a firetruck crashed with the plane and people died.
