The US National Transportation Safety Board (NTSB), investigating the Asiana Airlines Flight 214 crash, has cited mismanagement on the part of the pilots as a reason for the 2013 accident.
The Boeing 777 crashed short of the runway in San Francisco, killing three people and injuring 187 others a year back.
According to CNN, 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 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 report said.
Also, the investigators concluded that the crew was slow in its decision to abort the landing, even as the plane flew on a much less speed to avoid any mishap.
