Hello all! I'm glad there is a thread on this. I read the entire 322 page crash report and found a few things interesting I thought I would share.
There were four main factors in the crash.
1) Design Flaw (MCAS)
2) Pilot Error
3) Failure to Complete Maintenance-
The report states that Lion Air failed to maintain an airworthy aircraft. There were known issues with the AOA sensors that were never addressed or fixed. These problems persisted for several flights leading up to the accident flight.
4) Improper Maintenance Procedures-
Lion Air outsourced their minimal maintenance done on the original problems with the AOA sensors to a third party company. This company implemented unapproved procedures and installed uncertified parts in order to "fix" the AOA sensors. This fix was nullified almost immediately as the repaired sensors quickly failed again. With the sensors failing again, as stated in #3, Lion Air neglected to put the aircraft in maintenance to fix the problem. Instead, flying a plane with paying passengers that was not airworthy.
