Aircraft Accident/Incident Report

Santa Teresa, New Mexico 88008
Tuesady, August 6, 2013 8:56 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot was conducting agricultural spray operations to a small field with obstacles, including a power line, trees, and heavy construction equipment. His pull-up from the spray pass was too late and the airplane struck a tree on the edge of the field. After the tree strike, the pilot maneuvered to a forced landing, during which the airplane cartwheeled. The pilot stated that he regretted accepting the high level of risk involved with spraying the small, tightly confined field. The pilot also stated that his sleep was interrupted many times during the night before the accident, which would have affected both the quality and amount of sleep the pilot obtained during his reported sleep opportunity. The resultant fatigue would have likely affected both the pilot’s decision-making and flying performance on the day of the accident.

NTSB Probable Cause Narrative

The pilot’s failure to maintain clearance from a tree at the completion of an agricultural spray run. Contributing to the accident was the pilot’s decision to accept a high level of risk to spray a small field bordered by multiple obstacles and his fatigue due to interrupted sleep the night before the accident.
