NTSB narrative
The pilot conducted a preflight of the Navion A airplane confirming 20 gallons of fuel each in the left and right main tanks, but did not check the 20 gallon auxiliary tank. He then departed Mansfield, Massachusetts, flew a minimum of 69 statute miles and landed at Jaffrey, New Hampshire, subsequently departing without taking on fuel and flying for approximately two additional hours. He landed at Jaffrey again, and without shutting the airplane down, departed back to Mansfield. Shortly after departing Jaffrey and leveling off at 3,000 feet, the airplane's engine lost power. Unable to return to his departure field, and deeming his intended landing site as unsuitable, he executed a forced landing into tree tops. A post-crash examination of the airplane by an FAA inspector revealed no fuel in the airplane's fuel tanks, and no evidence of fuel leakage. The pilot stated that 'Due to the power setting I chose to run the airplane at, the length of the flight, and my negligence to visually check and only operate the airplane based on the fuel gauge readings, I believe that it was my mistake in exhausting the fuel.'
Probable cause
The pilot's inadequate aircraft preflight and subsequent failure to refuel the aircraft resulting in fuel exhaustion. A factor was the lack of suitable terrain to execute a forced landing.

Source notes (5)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
- API snapshot SHA-256: 7e27a1a1b19598dc5a75151128eaa3056950c136439b86e9348df45070c2c156; retrieved 2026-09-22T16:34:50.187Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: destination. The narrative states the pilot "departed Mansfield, Massachusetts" and, after landing at Jaffrey again, "departed back to Mansfield"; the recorded town Manchester is wrong, the airport code is kept.
