PlaneCrashThaiAirwaysFlight3111992 Biography

Thai Airways International Flight 311 was a flight from Bangkok, Thailands Don Mueang International Airport to Kathmandu, Nepals Tribhuvan International Airport. On 31 July 1992, an A310-304 on the route, registration HS-TID, crashed on approach to Tribhuvan. All 113 on board were killed. A number of frustrating and misleading communications (due partly to language problems and partly to the inexperience of the air traffic controller, who was a trainee with only nine months on the job) ensued between air traffic control and the pilots regarding Flight 311s altitude and distance from the airport. The captain asked four times for permission to turn left, but after receiving no firm reply to his requests he announced that he was turning right and climbed the aircraft to flight level 200. The controller handling Flight 311 assumed from the flights transmissions that the aircraft had called off the approach and was turning to the south, and he therefore cleared the aircraft to 11,500 feet (3,505 m), an altitude that would have been safe in the area south of the airport. The flight descended back to 11,500 feet, went through a 360-degree turn, passed over the airport northbound, and crashed on a steep rock face in a remote area of the Langtang National Park at an altitude of 11,500 feet.
