Incident
A military cargo aircraft transporting metallic pipes for a pipeline construction project was involved in a runway overrun incident. During the takeoff roll, the pilot-in-command encountered an unexpected situation and decided to abort the takeoff. The aircraft was unable to stop within the remaining runway distance, overran the end, and came to rest in a ditch located 50 meters past the runway threshold. The aircraft sustained damage beyond economical repair.
Probable Cause
The official investigation determined that prior to takeoff at Tyumen Airport, the crew was instructed to hold for several minutes while an Antonov AN-2 was landing. During this holding period, the crew activated the parking brake. When cleared for takeoff, the crew failed to release the parking brake. As a result, during the takeoff roll, the aircraft could not rotate because the parking brake was engaged and speed was insufficient. The crew did not notice these conditions in a timely manner.
Aftermath
All six crew members on board received minor injuries. The aircraft was declared a total loss. The investigation highlighted the sequence of events leading to the overrun, but no additional factors or recommendations were provided in the official findings.
