Not sure if this has been posted here. It is a very understandable explanation of what is wrong with the 737Max. Written by a guy who is a pilot and software developer.

Quite frightening to think the people who didn't know enough to write the original software, have written the "fix".

There is a lot of stuff out there, relying on one instrument that can basically cause the plane to crash and not mention this to a Pilot does seem odd.

As 258 passengers filed on to American Airlines Flight 191 at O’Hare International Airport the Friday before Memorial Day in 1979, nothing suggested that they would never reach Los Angeles.

Article on AA191 40 years ago.

And all because (if memory serves) someone was rushing to get an engine mounted back on a wing using an unapproved method.

Yes, this is a summery of the NTSB report:

".... the probable cause of this accident was the asymmetrical stall and the ensuing roll of the aircraft because of the uncommanded retraction of the left wing outboard leading edge slats and the loss of stall warning and slat disagreement indication systems resulting from maintenance-induced damage leading to the separation of the No. 1 engine and pylon assembly at a critical point during takeoff. The separation resulted from damage by improper maintenance procedures which led to failure of the pylon structure. …"

It was more along the lines of the airlines developing a method that saved 200 people hours per aircraft by removing engine and pylon together. AA and Continental used a fork lift and United used an overhead crane, the United method didn't seem to cause the issues that the AA and Continental method caused, after 191 went down both AA and Continental had other aircraft with damage from this procedure and were both fined, AA fined $500,000 and Continental fined $100,000.

McDonnell Douglas did not recommend this procedure but had no authority over how airlines performed maintenance.

Ohhhhh $600,000 in fines. That was worth 258 lives. Just over $2,300 a fatality.

I love aviation, but airlines make me sick.

American Airlines is having some labor issues.

From the linked article:
" American Airlines has filed a lawsuit against its mechanics unions, accusing them of an illegal slowdown campaign.

The airline is asking a federal judge to order the unions to stop. ...."

​​​​​​I wouldn't be surprised if the unions are willing to oblige.

Have to wait and see what the judge says.

Union could be working to rule, airlines often view this as a form of illegal slowdown when its not.
