In both cases, pilots had mere seconds to fight the MCAS function, which automatically forces the plane's nose downward, after it was accidentally triggered.
According to the report, the FAA had been made aware of MCAS, though "the information and discussions about MCAS were so fragmented and were delivered to disconnected groups" that it 'was hard to recognize the impacts and implications of this system'. Many critics say the FAA should take a bigger role.
Morocco's national carrier Royal Air Maroc (RAM) has suspended a deal to purchase two more Boeing BA.N 737 MAX jets after the same model of aircraft crashed in Ethiopia, a source from the airline told Reuters on Thursday.
"We welcome this scrutiny and are confident that our openness to these efforts will further bolster aviation safety worldwide", FAA Chair Steve Dickson said. The report said the office is overseeing Boeing's 737, 747, 767, 777, and 787 programs. In the interim, allegations that manufacturer Boeing rushed the plane out the door with a faulty design (particularly, its anti-stalling Manoeuvring Characteristics Augmentation System, MCAS), that it failed to implement stronger safety systems, that the FAA failed to properly inspect it have multiplied.
"With adequate FAA engagement and oversight, the extent of delegation does not in itself compromise safety", states the report, which is scheduled to be released officially later today (Oct. 11). The Southwest pilots' union, however, recently filed a lawsuit arguing that Boeing deliberately put profits before safety and "made a calculated decision to rush a re-engined aircraft to market to secure its single-aisle market share and prioritise its bottom line".
In the 737 MAX, the FAA initially delegated 40% of the certification tasks and boosted that figure as the five-year review progressed, including the review of MCAS.
Boeing pledged to work with the FAA on the recommendations.
"Boeing is committed to working with the FAA in reviewing the recommendations and helping to continuously improve the process and approach used to validate and certify airplanes going forward", the company said in a statement.
The panel included members from USA agencies, and aviation regulators from Europe and eight foreign countries including Canada and China.
It's claimed the FAA has already taken steps to address these recommendations, which in large has contributed to the prolonged grounding of the MAX, which is now expected to return early 2020.
