Emergency landing of aircraft near Vilyuisk following engine failure

No fatalities • Vilyuisk, Russia • Flight

An aircraft operating a scheduled service from Vilyuisk Airport experienced engine power loss and overheating, resulting in an emergency landing in a swampy area.

What happened

During a scheduled flight (number PI9977) departing from Vilyuisk Airport for Kyubeinde-Ugulet, the aircraft encountered significant mechanical issues shortly after takeoff. While maintaining an altitude of approximately 400 meters, the engine experienced a drop in oil pressure accompanied by overheating. Following the loss of engine power, the crew initiated an emergency return to Vilyuisk.

As the flight progressed, the engine failed completely. The captain attempted to perform an emergency landing in a marshy region situated 26 km northwest of Vilyuisk. Upon touchdown, the main landing gear became embedded in the soft terrain. The force of the impact caused the engine to be torn from the airframe, and the aircraft subsequently caught fire. Despite the intense flames that resulted in the total destruction of the aircraft, all 11 people on board—consisting of the crew and 9 passengers—managed to evacuate the wreckage without injury.

Findings

  • The engine experienced a critical loss of power due to overheating and a decrease in oil pressure.

Probable cause

The engine lost power following an increase in temperature and a drop in oil pressure during the initial climb.
