For any new followers to this thread: 5 pages... All it took was 5 pages of comments for the thread of a tragic airplane crash to devolve into “he said she said” bickering.. APC may or may not be anthropologic gold.

I know it's early but why take a chance?
It's very early. I have no issue flying it, but just need a few questions answered by the investigators.

Whatssamatta? One day I’ll run into Adlerdriver and buy a round. We’ll chew the fat and show off pics of the kids. Just sayin’.

Dude - I'm not sure why you've decided to focus on "indictment". I wish I had chosen another word now because you're off on a tangent. I wasn't accusing you of an indictment. I was trying to say that your statements about the write-ups and the crash indicated a bigger problem with local maintenance than manufacturer choices or design. That's all.


I'm not really on a tangent, I made a pretty straightforward response to a bunch of your points (which you chose not to address, only the "indictment" part) including how the 737 has never had a stab-trim related accident, and only finished with that part.

A friend of an acquaintance flies 777s for Ethiopian and was next in line for departure after the accident aircraft. According to him the accident aircraft crew reported they had unreliable airspeed to the tower before being switched over to the departure frequency. Don't know how that might play into the MCAS playing a role.

With bad AOA indications, could it be triggering a stall warning (and MCAS) while showing accurate airspeed, which leads the crew to believe the airspeed was unreliable?

But, it's not accurate to say they added a system that can fail catastrophically. They didn't. That's my the point. MCAS has no more potential for "catastrophic consequences" than the basic stab trim system or autopilot control on a 737-200 in 1967. Any of those systems can malfunction and the results of an IMPROPERLY handled malfunction would be the same. Boeing's not going to add "If the failure is determined to be MCAS, then blah, blah, blah........ to the Runaway Stabilizer procedures because it doesn't matter. The symptoms and solution of some kind of MCAS failure are basically the same as any other stab related malfunction. A pilot wouldn't need to know why his aircraft was pitching down uncommanded - just that it is and there are long established, proven procedures that he's supposed to follow.

Yes, and after you stated that "fact", you connected that fact to the crash which you have been implying and even outright saying was caused by MCAS.
I think you need to look up the word "indictment" because you seem to be making my use of it much more than it means in this case.
All I'm saying is that multiple write ups on a trim system over multiple flights followed by what appears to be a trim related crash looks a lot worse for that airline's maintenance practices than the aircraft manufacturer.
I certainly hope any max operator now is ready on the cutoff switches as the flaps cycle up. But sitting in their seats the lion air guys seem to have been presented with an indicated airspeed problem that then would look like a stall. At least it did to the MCAS. They didn’t have a runaway trim problem, they had an airplane that took control away from the pilots in a mistaken effort to assist them, as it was designed to do.

A million years ago in instrument training I had the pitot ice over in IMC when I did not turn on the heat. The airspeed needle just walked around the dial to max airspeed in about five seconds. Gets your attention. There was no increase in wind noise or any attitude excursions so I just assumed it failed. When we turned the heat on the reading came back to normal. Hate to think what could have happened if the aircraft had had an engaged autopilot that was wired to pitch up when it received a high airspeed reading. Maybe not the same as what may have happened here but similar.

Default Part 25 rules should be revisited

There are far to many aerodynamic bandaids that are permitted to pass the current standards. Not just this particular airplane, but a whole bunch of airframes. If the basic aerodynamics won't pass without the pushers, pullers and now AOA induced changes to primary and secondary controls then a new design of the wing platform should come into play.

Just my .02
