US to mandate design changes on Boeing 737 MAX 8

The United States will mandate that Boeing implement design changes by April that have been in the works for months for the 737 MAX 8 fleet after a fatal crash in October but said the plane was airworthy and did not need to be grounded after a second crash on Sunday.

An Ethiopian Airlines 737 MAX 8 bound for Nairobi crashed minutes after take-off on Sunday, killing all 157 aboard and raising questions about the safety of the new variant of the industry workhorse, one of which also crashed in Indonesia in October, killing 189 people.

Boeing confirmed the Federal Aviation Administration’s announcement late Monday that it will deploy a software upgrade across the 737 MAX 8 fleet “in the coming weeks” as pressure mounted. Two US senators called the fleet’s immediate grounding and a rising number of airlines said they would voluntarily ground their fleets.

The company confirmed it had for several months “been developing a flight control software enhancement for the 737 MAX, designed to make an already safe aircraft even safer.”

Boeing did not reference Sunday’s Ethiopian Airlines crash in connection to the software upgrade. The statement did express the company’s condolences to the relatives of the 157 people who died, however.

The FAA said the changes will “provide reduced reliance on procedures associated with required pilot memory items.”

The FAA also said Boeing will “update training requirements and flight crew manuals to go with the design change” to an automated protection system called the Maneuvering Characteristics Augmentation System or MCAS. The changes also include MCAS activation and angle of attack signal enhancements.

The FAA said in the notice made public that external reports are drawing similarities between the crashes in Ethiopia and Indonesia. “However, this investigation has just begun and to date we have not been provided data to draw any conclusions or take any actions,” according to the Continued Airworthiness Notification to the International Community for Boeing 737 MAX 8 operators.

US Transportation Secretary Elaine Chao told reporters regulators would not hesitate to act if they find a safety issue.

“If the FAA identifies an issue that affects safety, the department will take immediate and appropriate action,” Chao told reporters. “I want people to be assured that we take these incidents, these accidents very seriously.” Reuters
