Aircraft accident at Mirny Airport involving reverse thrust deployment

No fatalities • Mirny, Russia • Takeoff (climb)

An aircraft experienced an uncommanded reverse thrust deployment during its initial climb from Mirny Airport, resulting in a runway excursion and building impact.

What happened

During the initial climb phase immediately following takeoff from Mirny Airport, the aircraft experienced a malfunction involving the right engine's reverse thrust system, which deployed unexpectedly. This deployment caused the aircraft to bank sharply to the right, leading the right wing tip to make contact with the runway surface.

Following the wing strike, the aircraft lost directional control and underwent a crash landing. The momentum of the vessel caused it to veer off the runway, eventually coming to a stop after colliding with a nearby building. The aircraft sustained damage that rendered it a total loss.

Findings

  • The primary factor in the loss of control was the uncommanded deployment of the reverse thrust system on the right engine during the takeoff climb.
  • There were 12 occupants on board the aircraft during the incident.
  • All passengers and crew members managed to exit the wreckage, and there were 0 fatalities and 12 minor injuries reported.

Probable cause

The unexpected activation of the right engine's reverse thrust during the initial climb phase caused a significant roll and subsequent runway excursion.
