Ethiopian airlines pilots on flight 302 followed the emergency procedures as laid down by Boeing to recover unstable longitudinal stability before the plane nose dived to crash.
The Wall Street Journal‘s investigation report says, the plane crashed despite the steps were followed to regain control of the plane, which was repeatedly overrun by the software MCAS.
Following the Lion Air Boeing 737MAX flight 610 crash, Boeing issued an “Operations Manual Bulletin” advising airline operators how to address incorrect cockpit readings, when there is erroneous input from an AoA (angle of attack) sensor.
WSJ suggest that ’emergency procedures’ in the Boeing handbook may not have been sufficient enough to prevent a crash, based on preliminary finding.
The preliminary findings produced within 30 days of an incident are not final and subject to change as the investigation continues.
Pilots’ union spokesmen for Southwest and American told CNN, the self-administered course, which he took on his iPad, highlighted the differences between the Max 8 and the 737, but did not explain the MCAS feature.
On Tuesday, a new Senate investigation was launched after whistleblower reports raised questions about whether FAA inspectors who reviewed the Boeing 737 MAX for certification were properly trained.
