Boeing 737 MAX: Company reveals new software problem. Photo by the Independent

Boeing has revealed that its troubled 737 MAX jets are suffering from an additional software problem that regulators say must be fixed before the planes can be cleared to fly again.

Iran Press/America: As investigators in Ethiopia said a preliminary examination suggested the Boeing jet that crashed last month with the deaths of 157 passengers and crew was struck by excessive speed and was forced downwards by a wrongly-triggered automation system, new problems emerged for the airline back home in Seattle.

The Washington Post said a review by Boeing of the stall prevention system suspected of being behind the Ethiopian Airlines and a crash last year in Indonesia, had detected an “additional software problem”. It said the Federal Aviation Administration (FAA) had ordered the problem be addressed before the plane would be cleared for flying.

It said the company termed the problem “relatively minor” and was not related to the anti-stall system.

However, it is another headache for the company, struggling to respond to the global grounding of the jet with which it intended to compete with rival, Airbus.

Boeing’s CEO has apologised for the deaths and vowed to get to the bottom of what caused the incidents.

“We at Boeing are sorry for the lives lost in the recent 737 MAX accidents. I cannot remember a more heart-wrenching time in my career with this great company,” chief executive Dennis Muilenburg said.

He also said the release of the preliminary report in Ethiopia showed it was apparent that in both the crash in Africa and Indonesia, the manoeuvring characteristics augmentation system, known as MCAS, activated in response to erroneous angle of attack information.

“As pilots have told us, erroneous activation of the MCAS function can add to what is already a high workload environment. It’s our responsibility to eliminate this risk", Muilenburg said. 104/212
