Incident
On a training flight from Tehran-Mehrabad Airport to Rasht, the crew departed at 1233 LT. After successfully completing 14 touch-and-go maneuvers, they returned to the airport but forgot to lower the landing gear. The aircraft landed on its belly and slid on runway 09 for 30 seconds over a distance of 2,100 meters.
Despite the belly landing, the crew decided to take off again. As the aircraft climbed, the rear fuselage caught fire. The crew declared an emergency, manually extended the landing gear, and was cleared to land on runway 09. However, during the final approach, the aircraft became unstable, lost height, and crashed in a field 5 km short of the runway. The crash resulted in four crew members killed and three injured. The aircraft was destroyed.
Probable Cause
The official investigation identified several findings contributing to the accident: the crew failed to follow the approach checklist, forgot to lower the landing gear, exhibited poor coordination and lack of crew resource management, made a wrong decision to take off after the belly landing, and operated an aircraft that was not fit to fly following the belly landing and subsequent fire.
