Lion Air / Ethiopian Air similarity (updated)

If

  1. the Ethiopian Air crash was due to the same problem which caused the Lion Air crash, and
  2. Boeing was aware of the problem, and
  3. Boeing had not ensured that Ethiopian could handle the problem,

Then

Boeing has to answer for 157 deaths.


Update 1: Reuters reports that “The trim position of the stabilizer, which moves the jet’s horizontal tail, could help determine whether or not it was set nose down for a steep dive. …. …… part of a stabilizer found in the Ethiopian wreckage was in a unusual position similar to the Lion Air plane”.


Zero Hedge:

Boeing put MCAS in its planes as a protection against an aerodynamic stall, but in the case of the October flight, a sensor malfunction signaled that the plane was in danger when it wasn’t, causing it to dive automatically. Rather than switch off the motor triggering the dives, the pilots tried to counteract it with their controls until it dove into the sea.

The Ethiopian flight showed similar “highly unusual descents followed by climbs”. 

Peter Goelz, a former managing director at the NTSB said: “It certainly puts a magnifying glass on the MCAS system. There’s an implication that there were two similar accidents and that it likely involved the interaction of the MCAS system with the flight of the aircraft.”

Kevin Durkin, an aviation lawyer, said: “If you have a defective product and it turns out Boeing knew about it, this could easily expose them to punitive damages. The standard is whether the company engaged in conduct with a ‘conscious indifference to the safety of others’.”
