Ethiopian 737 MAX Pilots Unable Control Aircraft Despite Correct Procedures


The preliminary report clearly showed that the Ethiopian Airlines Pilots who were commanding Flight ET 302/10 March have followed the Boeing recommended and FAA approved emergency procedures to handle the most hard emergency situation created on the airplane.

Boeing issued the following statement regarding the release today of the preliminary investigation report of Ethiopian Airlines Flight 302 by the Ethiopian Accident Investigation Bureau (AIB) on the Boeing Max crash.

"Since repetitive uncommanded aircraft nose down conditions are is recommend that the aircraft control system shall be reviewed by the manufacturer", she said.

The aircraft was the same type of jet as the Indonesian Lion Air plane that crashed in October, killing 189 passengers and crew.

The suit filed Thursday in Chicago federal court on behalf of an American citizen who was on the doomed Ethiopian Airlines flight March 10 joins a growing pile of complaints against Boeing, as well as a criminal probe, after two 737 Max planes crashed within five months.

- Indonesia has advanced the planned release of its report on the Lion Air crash to between July and August, versus a previous schedule of between August and September.

The UAE has accepted an invitation to join the US Federal Aviation Administration's (FAA) review panel on the Boeing 737 MAX, a senior official told Reuters on Thursday. Flight crews will always have the ability to override MCAS and manually control the airplane.

- Experts believe a new flight control system, MCAS, on the jets, created to stop stalling by dipping the nose, may have been a factor in both accidents, with pilots unable to override it as their jets plunged after a faulty sensor indicated a stall.

"We remain confident in the fundamental safety of the 737 MAX", CEO Dennis Muilenburg said in a statement. Ethiopian officials had previously said readings from black box data showed "clear" similarities between the two flights.

A relatively new piece of software, the MCAS uses sensors in the nose of the aircraft to assess whether the plane is climbing at too steep an angle - an action that can cause it to stall - and adjusts accordingly.

Meanwhile, the Ethiopian government also on Thursday disclosed that the pilots had followed Boeing required procedures, but could not control the flight. The FAA has said it will review the software before allowing the Max to fly again.

The preliminary report, which has not yet been publicly released, does not come to a finding of probable cause.

A more in-depth report is expected to take several months, before a final report is due within a year.

However, Moges told the New York Times after the news conference that the pilots turned MCAS on and off, but she couldn't say how many times.

"If pilots sit there and follow the rules that have been given to them by the manufacturer, then they should be able to rely on the fact that they are correct", Hasse said.

"Understanding the circumstances that contributed to the Ethiopian accident is critical to ensuring safe flight", Boeing Commercial Airplanes Chief Executive Kevin McAllister said in a statement.
