Roberts Field Airport
Aircraft Accident/Incident Report

Redmond, Oregon 97756
Saturday, May 31, 1997 18:45 PDT

NTSB Narrative Summary Released at Completion of Accident

Prior to departing on a flight that the pilot estimated would take 18 to 20 minutes, he measured his fuel remaining by use of a dipstick. Based upon that measurement, he estimated that he had eight gallons of fuel remaining. While on a 45-degree entry to downwind at the destination airport, the aircraft's engine experienced a total loss of power. Although he was not able to make it to a runway, the pilot landed on a level area within the boundary of the airport. His touchdown was successful, but during the landing roll, the aircraft collided with rocks and high vegetation. After the accident, a total of 2.3 gallons of fuel was found in the wing tanks of the aircraft. According to the Owners Manual, 3.3 gallons of the total fuel load is unusable.

NTSB Probable Cause Narrative

the pilot's improper decision to depart on a flight without first ensuring the aircraft held sufficient fuel to reach his destination, which resulted in fuel exhaustion. Factors were the high vegetation and rocks at the location of the forced landing.
