What happened
During the final approach and landing phase, a twin-engine aircraft experienced a heavy impact with the runway. The force of this landing was sufficient to cause the tail section of the airframe to detach from the main fuselage. Following the initial impact, the aircraft's landing gear failed, leading to a loss of the undercarriage.
After the gear collapsed, the aircraft slid for several dozen meters along the surface. The friction and mechanical stress during this excursion caused the aircraft to burst into flames. Despite the intensity of the fire, all five occupants managed to evacuate the aircraft safely before the fire consumed the wreckage. The aircraft was subsequently destroyed.
Findings
Preliminary observations suggest that the aircraft may have experienced an engine failure in the period immediately preceding the landing attempt. The sequence of structural failures, including the separation of the tail and the loss of the undercarriage, was a direct result of the high-impact landing.
