A local training flight ended in a fatal crash when the aircraft entered an uncontrolled dive during aerobatics at 800 metres. Both pilots on board were killed.

What happened

The incident occurred during a local training flight departing from Rostov-on-Don-Olginskaya Aerodrome. While maintaining a cruising altitude of 800 metres, the pilot initiated aerobatic manoeuvres. During this sequence, control of the aircraft was lost, causing it to enter a steep dive. The airplane subsequently impacted the ground in a field. Both pilots were killed in the accident.

Findings

The investigation identified several contributing factors leading to the loss of control. The primary issue was that aerobatic manoeuvres were attempted at an altitude deemed unsafe for such activities. Additionally, the aircraft entered the dive at excessive speed, which likely reduced the pilot's ability to recover. The official findings also cited insufficient training for the specific manoeuvres performed, poor piloting techniques, and a lack of operational discipline.

Probable cause

The accident resulted from performing aerobatic manoeuvres at an unsafe altitude combined with insufficient pilot training and poor technique.
