An official U.S. report has determined the cause of the Asiana Airlines crash at San Francisco International Airport in July last year.
The U.S. National Transportation Safety Board in a board meeting on Tuesday finalized the report on the accident after an almost year-long investigation.
As probable causes of the accident, the report points to the pilots unwittingly releasing the autothrottle, failing to monitor either the speed or the flight mode, and mismanaging the descent during the visual approach. It also says it was too late for them to try a "go-around."
As contributing factors it cites the complexities of the autothrottle and auto flight system, "nonstandard" communication about their use between the pilots, and inadequate training on the planning and executing of visual approaches.
Boeing reportedly disagrees with the report and said there is no evidence that the 777’s auto flight system contributed to the crash.
Asiana faces a flood of lawsuits from passengers and victims' families, while Boeing could be obliged to shoulder some of the compensations.
The jet, which took off from Incheon International Airport, struck a seawall near the runway while landing at San Francisco Airport. Three of the 291 passengers were killed and about 180 others injured.
