The air force has listed three possible causes leading to the crash of an F-16 fighter jet early this month in Chaiyaphum province, according to Move Forward Party list-MP Kasemsan Meethip.
The aircraft crashed on March 8 in a field in Chatturat district during a training mission. The pilot managed to eject safely. The House committee on the military on Friday invited the air force to give information about the crash.
Citing a document handed to members, Mr Kasemsan said the oxygen system, the G-suit or pilot health were listed as possible causes. However, the cause has yet to be established.
The probe shows the oxygen system before the flight was functioning properly. The pilot was in good health, and his blood test showed no traces of alcohol or narcotics.
The aircraft had clocked more than 6,000 hours and the on the day of the crash the pilot was practising a dogfight and appeared to lose control temporarily.
