NTSB Narrative Summary Released at Completion of Accident

The 3,300-hour commercial pilot lost control of the airplane while circling an area of disturbed dirt along the path of a buried pipeline during an aerial observation flight (pipeline patrol). The operator reported that pipeline patrolling is normally performed from an altitude of 400 to 500 feet above the ground. The range of the airplane, when all tanks are full of fuel is 6 hours; however, the company procedures are to not exceed 4 hours between refueling stops. The operator reported that the pipeline being patrolled at the time of the accident was aligned on a heading of 50-60 degrees. The prevailing winds at the time of the accident were reported from 030 degrees at 15 knots, gusting to 19 knots. The hand-held GPS on-board the airplane provided the track of the airplane to impact with the ground. No anomalies were found with the airframe or engine that could have prevented normal flight operation.

NTSB Probable Cause Narrative

The pilot's failure to maintain airspeed while maneuvering, resulting in an inadvertent stall . Factors contributing to the accident were the low altitude and the prevailing high winds.
