Aircraft Accident/Incident Report

Naches, Washington 98973
Friday, July 11, 1997 9:49 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that during a preflight on 7/11/97, she checked the aircraft's fuel quantity using a dip stick, but was interrupted and had to begin again. She reported the left tank was '1 inch down,' and right tank was 'full.' The aircraft was operated on the ground for 10 to 15 minutes at 1,000 RPM before taking off from the Yakima Airport, which was logged at 0832. At 0949, Yakima Tower received a radio transmission from the aircraft indicating a power loss. Subsequently, the pilot executed a forced landing onto soft terrain. During the landing, the nose gear collapsed, and the aircraft nosed over. An FAA onsite examination revealed no evidence of fuel in the left tank and about one cup in the right tank. No evidence of fuel spillage was noted at the site, and no evidence of any fuel leakage from the fuel system was found. The pilot stated that on the evening before the flight, she contacted the fixed base operator (FBO) to have the aircraft serviced with fuel. FAA examination of FBO documentation revealed no record of the aircraft having been refueled since June 14th. The aircraft had been flown approximately 2.5 hours on the day before the accident. The aircraft's total usable fuel capacity was 38 gallons. Estimated fuel consumption of the aircraft was 6.0 to 9.7 gallons/hour.

NTSB Probable Cause Narrative

inadequate preflight by the pilot, and subsequent fuel exhaustion, which led to a forced landing and subsequent nose over of the aircraft. Related factors were: the FBO did not refuel the aircraft as requested, and soft terrain was encountered during the forced landing.
