The third hull loss occurred on July 6, 2013, when a 777-200ER, operating as Asiana Airlines Flight 214, crashed while landing at San Francisco International Airport after touching down short of the runway. The 307 surviving passengers and crew on board evacuated before fire destroyed the aircraft. Two passengers, who had not been wearing their seatbelts, were ejected from the aircraft during the crash and were killed. A third passenger died six days later as a result of injuries sustained during the crash. These were the first fatalities in a crash involving a 777 since its entry into service in 1995. The official accident investigation concluded in June 2014 that the pilots committed 20 to 30 minor to significant errors in their final approach. Deficiencies in Asiana Airlines' pilot training and in Boeing's documentation of complex flight control systems were also cited as contributory factors.
