Russian Air Force — Flight Unknown

A Russian Air Force Antonov An-26 military transport plane crashed into a cliff face approximately 25 kilometers east of Sevastopol during a scheduled flight over the Crimean Peninsula. The aircraft was carrying 23 passengers and six crew members, all of whom were killed in the impact. The Russian Defense Ministry initially cited a technical malfunction, but subsequent investigative findings attributed the disaster to human error involving a premature descent during the landing approach.

Investigation Summary

The aircraft was conducting a routine military transport mission on March 31, 2026, when it lost contact with air traffic controllers at approximately 18:00 local time. Search and rescue teams located the wreckage on a cliff face in the mountainous terrain of Crimea. Initial statements from the Russian Defense Ministry suggested a technical failure and explicitly ruled out external interference or 'damaging interference.' However, the investigation concluded that the flight crew initiated a descent well before reaching the prescribed approach point for the airfield. This premature descent led to a Controlled Flight Into Terrain (CFIT) when the aircraft struck a rock face roughly 30 kilometers from its intended destination.

Final Conclusions

The investigation determined the cause of the crash was human error. The flight crew performed a premature descent during the landing approach, which resulted in a collision with a cliff 30 km from the airfield. All 29 occupants were confirmed dead at the scene.

Systems & Failure Modes

i

Altimeter

Instruments used to measure the aircraft's altitude above a fixed level; errors in monitoring or setting these can lead to premature descent.

i

Terrain Awareness and Warning System (TAWS)

A system designed to prevent CFIT by providing alerts to the crew if the aircraft is in danger of striking the ground.
