Accident Overview
A pilot flying over a suspected oil leak in a pipeline was involved in an accident while attempting to get the attention of witnesses on the ground. The aircraft was observed circling at approximately 500 feet above ground level (agl) over the suspected leak location.
Witness Accounts
Witnesses reported that the airplane was in a left bank of 60 to 90 degrees. During the turn, the aircraft lost altitude until it struck the ground. The impact occurred on the left wing, causing the airplane to cartwheel. The witnesses stated that the pilot appeared to be trying to get their attention.
Pilot and Inspector Statements
The pilot later told an FAA inspector that he could not remember the event. The FAA inspector stated that the pilot's attention was diverted to the witnesses, and that the pilot had stalled or was about to stall the aircraft in the high bank angle.
