Incident Overview
During the final approach to Novosibirsk-Yeltsovka Airport, at an altitude of 140 meters and a speed of 260 km/h, approximately 3 kilometers from the runway threshold, both engines ceased operation simultaneously. The aircraft subsequently lost altitude, struck overhead power lines, and collided with the embankment of a railway line. The crash occurred 2,010 meters short of the runway, near a wooded area, where the aircraft burst into flames. The captain sustained injuries, while nine other occupants were killed.
Investigation Findings
The official investigation determined that the dual engine failure resulted from an error by a crew member who inadvertently switched off the electrical systems supplying both engines while attempting to deactivate the anti-icing systems. The crew's response was deemed inappropriate, as they delayed in identifying the failure and failed to feather both propellers. The aircraft was not equipped with an automatic feathering system, and the combination of the late crew reaction with both propellers non-feathered increased aerodynamic drag, causing the aircraft to lose height and crash.
