Executive Summary:On March 3, 2001, about 1448 local time, Thai Airways International Public Company Limited (Thai Airways) flight 114, a Boeing 737-400, HS-TDC, was destroyed while the airplane was parked at gate 62 of the Bangkok International Airport, Thailand. The airplane was being prepared for a scheduled domestic passenger flight to Chiang Mai, Thailand, when it exploded and was subsequently destroyed by fire. The Aircraft Accident Investigation Committee of Thailand (AAIC) notified aviation authorities in the United States of America (the State of Manufacture) who sent an Accredited Representative to participate in the investigation.

The AAIC determines that the probable cause of this accident was an explosion of the CWT resulting from ignition of the flammable fuel/air mixture in the tank. The source of ignition energy for the explosion could not be determined with certainty, but the most likely source was an explosion originating at the CWT pump as a result of running the pump in the presence of metal shavings and a fuel/air mixture.
