Ethiopian 737 MAX 8 crash
#72
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’.

That's exactly what I'm saying. I wish I still had the pictures some of our deadheading pilots took of a Chinese crew taking off with 6-inches of snow on their wings (yes, pictures taken from inside the a/c on takeoff roll).
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.

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.

I'm not defending Boeings approach to putting MCAS on the Max and blowing off proper communication.
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.

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.

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.
