(Reuters) - Boeing Co’s safety analysis of a new flight control system on 737 MAX jets had several crucial flaws, the Seattle Times reported on Sunday.

Boeing’s safety analysis of the flight control system called MCAS (Maneuvering Characteristics Augmentation System) understated the power of this system, the Seattle Times said, citing current and former engineers at the U.S. Federal Aviation Administration (FAA).

The FAA also did not delve into any detailed inquiries and followed a standard certification process on the MAX, the Seattle Times reported citing an FAA spokesman.

The report also said both Boeing and the FAA were informed of the specifics of this story and were asked for responses 11 days ago, before the crash of an Ethiopian Airlines 737 MAX last Sunday, killing all 157 people on board. The same model flown by Lion Air crashed off the coast of Indonesia in October, killing all 189 on board

Boeing was not immediately available for comment.

The FAA did not immediately respond to requests for comment.
