At 12:09 p.m., Tran Ngoc Duy piloted the aircraft as a training session. At 12:27 p.m., while landing, the aircraft encountered an issue.
The pilot was ordered to parachute out of the aircraft, but he tried to fix it instead. The aircraft eventually crashed and he died.
Duy, 31, from Yen Bai Province, was the Deputy Squadron Commander and Deputy Chief of Squadron 1, part of Air Force Division 921.
The Ministry of National Defense has called on the air and anti-air military branch and other relevant units to resolve the consequences and determine the cause.
The Soviet-developed Su-22 fighter jet has been in service since the 1970s, with Vietnam acquiring a limited number of Su-22/UM aircraft starting in 1979.
