Ethiopian Crash Report Indicates Pilots Followed Boeing’s Emergency Procedures


At a information convention on Thursday, Dagmawit Moges, Ethiopia’s minister of transportation, mentioned the flight crew had “performed all the procedures, repeatedly, provided by the manufacturer, but were not able to control the aircraft.”

The report, which might change within the coming months when it’s accomplished, doesn’t rule out the potential for pilot error within the Ethiopian crash. And some pilots within the United States raised doubts about whether or not the issues on board had been correctly dealt with.

“They did not follow the Boeing procedures,” mentioned Hart Langer, a former Pan Am pilot and United Airlines government. If the pilots had used the electrical controls to tug the nostril up extra, he mentioned, they’d have been in a position to get well the aircraft.

“Had they done that, it would have cut out the MCAS input,” he mentioned.

When Boeing outlined the emergency course of in November after the Lion Air catastrophe, many pilots had been assured that the brand new directions had been sufficient to keep away from a crash. However, pilots didn’t take a look at the up to date procedures in flight simulators, as a result of few airways had them for the 737 Max.

The issues with the Ethiopian Airlines flight began virtually instantly after takeoff, in line with the report, amplifying the strain for pilots to behave. About two minutes after takeoff, a security system warned, “Don’t sink,” a number of instances.

A sensor that measures the angle at which the aircraft is flying started producing misguided readings, suggesting that the aircraft was about to stall. There are two so-called angle of assault sensors on the aircraft, and the one on the left started giving readings almost 60 levels totally different from the one on the best. The defective knowledge activated the software program that routinely pushed down the nostril of the aircraft.
