An airplane touched down left of centerline on a closed, rough dirt strip, resulting in loss of directional control and collision with a fence and ditch. No mechanical failures were reported.

What happened

The accident occurred while the aircraft was attempting to land on a dirt strip that was not maintained for regular air traffic operations. The surface conditions were described as rough and closed to normal use. Upon touchdown, the airplane did not align with the runway centerline, instead touching down to the left side.

Following the initial contact with the ground, the pilot was unable to maintain directional control of the aircraft. Unable to keep the plane on the paved or prepared surface, the airplane veered off the left side of the intended path. It then collided with a fence located near the edge of the strip and subsequently encountered a ditch.

The investigation

Examination of the event revealed no evidence of pre-accident mechanical issues. Investigators found no reported mechanical failures or malfunctions with the airplane prior to the accident sequence. The loss of control appears to have been directly related to the surface conditions and alignment at touchdown rather than equipment failure.

Probable cause

The pilot's inability to maintain directional control during landing on a closed, rough, unmaintained dirt strip, which resulted in the airplane leaving the runway surface and colliding with a fence and ditch.
