What happened
During a night-time local training mission at Migalovo Air Base, the crew was engaged in performing touch-and-go maneuvers. During one of these operations, the aircraft approached the runway in a nose-down attitude. This orientation caused the nose landing gear to strike the runway surface with excessive force.
Upon impact, the nose gear penetrated the aircraft floor directly behind the cockpit area. The momentum of the landing caused the aircraft to slide for several dozen meters along the runway before it finally came to a stop.
Findings
All four crew members successfully evacuated the aircraft without injury. However, the aircraft sustained severe structural damage, including a wrinkled fuselage, which rendered the airframe a total loss. The primary factor in the accident was the incorrect pitch attitude during the landing approach.
