Probable cause
The pilot's inadequate in-flight planning/decision, which resulted in a loss of engine power.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot reported that while he was cruising at 5,500 mean sea level the engine quit, and he thought that he had run out of fuel. The Federal Aviation Administration inspector who responded to the accident site was not able to locate any fuel in any of the fuel tanks, and there was no indication of a fuel leak.
Factual narrative
History of flight
On August 9, 2003, about 0945 Pacific daylight time, a Lefever experimental Skybolt, N94PL, had a hard landing while making an emergency landing to a field near Mount Hamilton, California. The pilot/owner was operating the airplane under the provisions of 14 CFR Part 91. The commercial pilot, the sole occupant sustained minor injuries; the airplane sustained substantial damage. The personal cross-country flight departed Lodi Airport Lodi, California, about 0900 en route to San Martin, California. Day visual meteorological conditions prevailed, and no flight plan had been filed. The primary wreckage was at 37 degrees 22 minutes north latitude and 121 degrees 38 minutes west longitude.
The pilot reported that while he was cruising at 5500 msl the engine quit. He thought that he had run out of fuel. The FAA inspector who responded to the accident site was not able to locate any fuel in any of the fuel tanks. There also was no indication of any fuel leaks.
The pilot said he had flown about 1and 3/4 hours since refueling the airplane. The airplane holds enough fuel in the main tanks for approximately two hours flight time. The airplane is equipped with an additional fuel tank, but the pilot said he only uses it for ferry flights.
