Post-takeoff crash near Stalino Airport due to dual engine failure (CCCP-L1381)

What happened

The incident occurred immediately after departure from Stalino Airport. While the aircraft was climbing to an altitude of approximately 90 meters, it experienced a critical mechanical failure involving both powerplants. The right-hand engine oversped, while the left-hand engine lost all thrust. This dual-engine dysfunction caused the airframe to stall. Unable to maintain controlled flight, the aircraft struck an electric pole before impacting a house situated in close proximity to the airport perimeter. The collision resulted in a post-crash fire that destroyed the airframe. Ten people died in the accident: eight occupants on board and two residents of the building. One crew member sustained serious injuries.

Findings

Investigations identified a structural shortcoming in the screw regulator as the root cause of the right engine overspeed event. The left engine was too heavily damaged by fire to allow for a definitive determination of its failure mode. Additionally, the inquiry concluded that the crew's response to the simultaneous loss of power on both engines was not appropriate, serving as a significant contributing factor to the outcome.
