Lion Air’s founder hits out at Boeing
The co-founder of Indonesia’s Lion Air, one of two airlines that lost passengers and crew in recent crashes involving the 737 MAX, has lashed out at Boeing’s handling of the accidents as the potential business fallout from the jet’s grounding intensifies.
Translated from Dutch NOS TV today:
Mechanical problems and design errors contributed to the crash of a Boeing 737 MAX 8 of airline Lion Air in October last year. Indonesian researchers shared those conclusions with the relatives of the 189 victims of the air disaster. The findings of the study will be presented later this week.
The flight from Jakarta to Pangkal Pinang on the island of Bangka crashed into the sea last year. All people on board were killed.
The research revealed, eg, that the new MCAS system was vulnerable because it was based on only one sensor. The sensor was set incorrectly after a previous repair. Other technical aspects of the aircraft were also not in order.
Furthermore, manuals about the systems were missing on board, eg, about the system that warns pilots if the aircraft loses altitude. …
A total of 55 lawsuits were brought against the US American corporation in Indonesia.
All Boeings 737 MAX types have been grounded since March this year after another aircraft crashed, this time in Ethiopia.
Immediately after the crash in Ethiopia, the US Department of Justice launched a criminal investigation into the way in which the aircraft were inspected by Boeing. The role of the American aviation authority FAA is also being investigated. Earlier, the Seattle Times reported that Boeing, which has its headquarters in Seattle, was given too much room to inspect systems itself. The FAA is said to have put pressure on its own engineers to have Boeing carry out that inspection.
