Ethiopia Set to Release Preliminary Report Into Boeing 737 MAX Crash

Ethiopia will release a preliminary report on Monday into the cause of an Ethiopian Airlines crash that killed 157 people last month and led to the worldwide grounding of U.S. planemaker Boeing’s top-selling 737 MAX jet.

The report will be closely examined for clues to any similarities between the March 10 accident and a Lion Air crash in October, also involving a 737 MAX, that killed 189 people.

The stakes are high, with Boeing trying to hold on to nearly 5,000 MAX 737 orders; air safety regulators facing questions over their scrutiny of the aircraft; and airlines and victims’ families looking for answers – and potentially, compensation.

Liability claims related to the Ethiopian crash and 737 MAX grounding could be the largest aviation reinsurance claim outside of war on record, broker Willis Re said on Monday.

Separately, Norwegian Air said its chief executive Bjoern Kjos would travel to meet Boeing in Seattle on Monday.

Norwegian, which has 18 737 MAX 8 in its fleet and is scheduled to take delivery of dozens more in the coming months and years, said last month it would seek compensation from Boeing over the grounding.

Ethiopia’s foreign ministry spokesman Nebiyat Getachew said the preliminary crash report would be released by the Ministry of Transport on Monday, although a time had not yet been set.

Flight 302 from Addis Ababa to Nairobi crashed six minutes after takeoff. Citizens of more than 30 nations were on board.

Three people briefed on the matter told Reuters on Friday that an anti-stall system at the center of a probe into the Lion Air 737 MAX crash was also at play in the Ethiopian accident.

Data pulled from the Ethiopian Airlines flight recorder suggests the so-called MCAS system, which pushes the nose of the jet downward, had been activated before the plane plunged to the ground, the people said, speaking on condition of anonymity ahead of the interim official report.

That was the second related piece of evidence to emerge from the black boxes of the Ethiopian flight after an initial sample of data recovered by investigators in Paris suggested similar “angle of attack” readings to the Lion Air crash.

These initial airflow readings from the Ethiopian jet, first reported by Reuters, refer to stall-related information needed to trigger the automated nose-down MCAS system.
