What happened
The incident occurred while the pilot was attempting to execute a crosswind landing. During the approach and touchdown phase, the pilot lost directional control of the airplane. In an effort to avoid overrunning the paved surface, the pilot elected to land on the grass area adjacent to the runway.
Conditions on the grass were wet, which significantly reduced traction and braking effectiveness. As a result, the pilot experienced difficulty in stopping the aircraft within the available distance. The airplane continued forward, traversing a snow bank located along the edge of the airfield. This impact caused the aircraft to swerve laterally toward a nearby hangar structure.
The investigation
Examination of the scene revealed that the left wing of the airplane struck the hangar during the uncontrolled excursion from the runway environment. The wet grass and subsequent snow bank contact contributed to the loss of directional stability and the final trajectory of the aircraft.
