Ethiopian Airlines crash: Pilot did not receive training on Boeing 737 Max 8 simulator, sources say

Plane maker said experienced pilots needed little training for new model before two planes fatally crashed

The pilot of Ethiopian Airlines Flight 302 was never trained on the Boeing 737 Max 8 simulator before the plane crashed, even though the airline was one the first to installs the simulator, according to airline sources.

The people, who spoke on condition of anonymity because Ethiopian Airlines had not authorised disclosure of the information, said the carrier had the Max 8 simulator up and running two months before Flight 302 crashed.

Boeing has said that experienced 737 pilots needed little training for the new Max 8, an assertion that has now come under close scrutiny by regulatory officials and pilots at other airlines.

Two of the planes have fatally crashed in the past five months, and regulators around the world grounded all Max 8s last week.

The captain of Flight 302, Yared Getachew, who had 8,000 hours of flying experience including on the 737, took a refresher course on a different simulator in late September and early October, according to one person familiar with the airline.

He was not due for another round of simulator training until after the crash on 10 March, they said.

It was unclear if the second pilot on Flight 302, first officer Ahmednur Mohammed, had trained on the Max 8 simulator. And it was not clear if the airline had used the simulator for refresher courses it requires pilots to take every six months, or only to train new pilots.

Still, use of the simulator by Ethiopian Airlines means the carrier was among the few in the world that not only had a working simulator for Boeing Max jets but was using it a few months after the first Max 8 crash, Lion Air Flight 610.

Despite Boeing’s assertions that the plane was safe, the crashes have raised questions about whether Boeing and its US regulator, the Federal Aviation Administration (FAA), did enough to train pilots on how to deal with the Max 8’s new features – in particular an automated system to prevent stalls.

Boeing said that pilots who had flown earlier models did not need additional simulator training, and even after the October crash in Indonesia, the FAA agreed.

Many pilots learned the new features of the Boeing Max on an iPad, and many were not originally informed of the existence of the automated system, which can push the plane’s nose down if it is approaching a stall.

The Ethiopian and Lion Air flights crashed minutes after takeoff and showed similar up-and-down oscillations before fatal nose-dives. A central focus of the Indonesian investigation is the possibility that the automated system pushed the nose down into a fatal dive because of inaccurate input from a sensor.

The Ethiopian Flight 302 crash killed all 157 aboard and the Lion Air Flight 610 crash killed all 189.

Even if both pilots on Flight 302 had trained on the simulator, it is unclear if such preparation would have included manoeuvres to deal with the kinds of problems they may have faced.

After the Lion Air crash, Ethiopian Airlines also shared with its pilots Boeing’s instructions on how to deal with the kind of problems Lion Air pilots appeared to have encountered, the people close to Ethiopian Airlines operations said.

In a bulletin issued in November, Boeing said that emergency procedures that applied to earlier 737 models would have corrected the problems that may have contributed to the Max 8 crash in Indonesia.

Pilots for Ethiopian Airlines, who declined to speak on the record, said they paid close attention to bulletins issued by aircraft manufacturers, especially following an accident. One pilot said failing to read the bulletins would be tantamount to “walking out of your house naked.”

The Ethiopian crash has brought new scrutiny to the system Boeing put in its new Max planes to prevent stalls, called Mcas. The system was designed to compensate for changes to the aerodynamics that arose from alterations to the size and position of the engines on the wings.

The pilots on the doomed Lion Air flight did not appear to understand why the jet was tipping downward and how to correct that problem. One flipped through a technical manual, and the other began to pray, according to the cockpit voice recording.

An investigation is still underway to determine what caused the crash in Ethiopia.

A possible fault in the Mcas system is part of the inquiry, and the authorities in Ethiopia have said that a preliminary review of the “black boxes” – voice recording and flight data – revealed similarities to the Indonesian crash.

But experts have cautioned that any conclusions at this stage of an investigation are preliminary and could change.

On Wednesday in Washington, the FAA published a notification to regulators in other countries reiterating that Boeing was preparing a software upgrade for the 737 Max along with training to accompany the updated software.

The FAA said its review of the new software and training was “an agency priority, as will be the roll-out of any software, training or other measures to operators of the 737 Max”.

The message from the FAA did not reveal any new information about what may have led to the crash in Ethiopia.

“Understanding the circumstances that contributed to this accident is critical in developing further actions and returning aircraft to service,” the FAA said.

In a further sign of scrutiny facing Boeing and the FAA, a Senate subcommittee on aviation and space said it was planning a hearing next Wednesday on airline safety.

“In light of the recent tragedy in Ethiopia and the subsequent grounding of the Boeing 737 Max aircraft, this hearing will examine challenges to the state of commercial aviation safety, including any specific concerns highlighted by recent accidents,” the subcommittee said in a statement.
