On 15 November 2017 the Let L-410 Turbolet operating the flight crashed short of the runway at Nelkan Airport, killing all but one of the seven people on board.

[3][4][5] The Interstate Aviation Committee (Russian: Межгосударственный авиационный комитет) investigated the accident with assistance from the Czech Air Accidents Investigation Institute (Czech: Ústav pro odborné zjišťování příčin leteckých nehod), representing the state of manufacture of the aircraft.

The cause of the accident was that the propeller on the right hand engine had gone into negative pitch in flight, leading to a loss of control.

[3] At the time of the accident, there were no instructions given to pilots for use in the event of a propeller going into beta range in flight.

Following the accident, and evidence being found of other occurrences, an instruction was issued that the affected propeller was to be feathered and the flight completed on one engine.
