Confidence Rating: Accident investigation report completed and information captured
The Antonov 2R was engaged in an aeromagnetic survey flight. On board were two crew members and one passenger. During landing rollout the aircraft suffered a runway excursion. The left hand main landing gear leg failed as the aircraft came to rest on rough terrain.

CAUSE (translated from Russian):
The most likely cause of the accident with the AN-2 RA-17812 were uncoordinated actions of crew members after landing, when the second pilot transferred control to the PIC for braking and rollout, which with the presence of crosswind from the left within the allowable limits, led the aircraft to roll off the side of the runway, causing damage to the aircraft.

Contributing factors, most likely, were:
- design features of the An-2 RA-17812, associated with the possibility of braking the wheels of the landing gear only from the PIC seat, and the absence of a locking mechanism for the tail wheel;
- absence of information in the An-2 Aircraft flight manual (AFM) and ALROSA documents on the transfer of controls after landing and corresponding commands when the copilot is landing.
