Aircraft.
The aircraft was a Hawker-Siddeley HS 748 with registration HS-THB, built in 1964. The plane had completed 12,791 flight hours at the time of the accident.
Accident.
The flight took off from Khon Kaen Airport for Don Mueang International Airport in Bangkok, Thailand. After about 40 minutes, Flight 231 was on approach to the airport, planning to land on runway 21R. It entered an area of rain, which turned out to be a severe thunderstorm, at 1500 feet. About a minute after entering the storm, a downdraft struck the plane, which caused the nose to go up and the plane to stall.
The aircraft then went into a nose dive, which the pilot tried to pull the aircraft out of. The Hawker then banked slightly to the right, and was almost out of the dive when it crashed into the ground. The plane then slid for 510 feet and broke up at 06:55. The accident killed 44 of the passengers and crew; the other 9 people aboard were injured.
