Pilots botched the approach and landing of Asiana Airlines Flight 214 in San Francisco nearly a year ago, causing a crash that killed three people and injured 187 others, U.S. safety investigators concluded on Tuesday.
But the National Transportation Safety Board also found that crew training and the complexities of a key flight system on the Boeing 777 and how it was described in operating manuals contributed to the July 6 disaster.
Investigators, however, primarily faulted the crew of the Korean-based carrier for not fully executing intricate systems of the jetliner packed with more than 300 people before it struck a seawall and careened down the runway trailing sparks and debris.
In a final report on their probe, the board found that the flight crew mismanaged the plane's descent being carried out without the help of navigational instruments and one of the pilots unintentionally deactivated a system that automatically regulates airspeed.
The crew also delayed its decision to abort the landing with the plane flying too slowly to avoid catastrophe, investigators found.
