Ethiopian 737 Max 8 crash and Fallout

MCAS or runaway trim?

It’s the runaway trim. The way we get it to trim quicker though in the NG is to do it with flaps out and start it off with IAS disagree. In which we set 10° and 80% N1.

It seems they (Boeing) barely understood any failure modes. I would have thought it was obvious to test a system (MCAS) for a situation when its key input (AOA vane or sensor) might fail. Maybe they did, and declared the test as passed after a single simple recovery without seeing it through to the bitter end.

Maybe they didn't test it failing seconds after takeoff,,,,

With an unwarned crew, of non test pilots....they never will. Even Boeing would like their aircraft back.

I think the USN have also stopped accepting P-8 Poseidon’s due to build quality issues.

Latest piece from the ABC, questioning if testing is the answer.

How will Boeing recover

How the Boeing 737 Max Disaster Looks to a Software Developer

Boeing produced a dynamically unstable airframe, the 737 Max. That is big strike No. 1.
Boeing then tried to mask the 737’s dynamic instability with a software system. Big strike No. 2.
Finally, the software relied on systems known for their propensity to fail (angle-of-attack indicators) and did not appear to include even rudimentary provisions to cross-check the outputs of the angle-of-attack sensor against other sensors, or even the other angle-of-attack sensor. Big strike No. 3.

None of the above should have passed muster.

Will the public including myself want to fly the 737 8 Max after eventual approval from the FAA etc given all this? I don't think so and airlines will need to take this into account with their existing and future orders....could thisl lead to the eventual end of the 737 Max?...Boeing will disagree....

How the Boeing 737 Max Disaster Looks to a Software Developer

It’s an interesting article...and the last sentence sounds especially familiar.

A LionAir co-founder made some comment last week. I think the Boeing Executive in charge of that relationship has quite a bit of fence mending to do.

Rusdi Kirana said a recent apology by Boeing over the 346 lives lost in the two disasters, firstly at Lion Air in October and then at Ethiopian Airlines last month, stood in contrast to what he viewed as hasty earlier criticism of Lion Air’s pilots.

Boeing sees me as its 'piggy bank', Lion Air co-founder says

The co-founder of Indonesia's Lion Air, one of two airlines that lost passengers and crew in recent crashes involving the 737 MAX, has lashed out at Boeing's handling of the accidents as the potential business fallout from the jet's grounding intensifies.

Wow- this getting worse and worse for Boeing. Now the Dreamliner in trouble as well? Something must be seriously wrong with Boeing Senior management.

Whilst I am not making an inference one way or another, you have to remember that not too long after the 738 had a couple of runway overruns, a number of Boeing staff/union members made comment about the 738 assembly due to the way the aircraft would break up on impact. In fact I am sure there is an Al Jazeera documentary on it, the name escapes me at the moment.

This tale never stops, does it? If it wasn’t for people having died, I’d be getting popcorn now...

This tale never stops, does it? If it wasn’t for people having died, I’d be getting popcorn now...

But, if it wasn't for people having died, Boeing would still be making aircraft with MCAS version 1, and simultaneously telling the world how safe their jets are.....

and this is the most frightening part...how much doesn't the public know? or how much do the regulators in charge of safety know or don't know.

 

[jb747]

......or how much do the regulators in charge of safety know or don't know.

I wasn't aware of just how little the regulators knew (or know). Perhaps that's why the likes of CASA come down so hard on individuals...as they have absolutely no influence over the large corporations. In any event, it's shown the FAA (and perhaps all if its ilk) to be quite useless when it comes to ensuring safety.
