NTSB narrative
The pilot was conducting the return leg of a cross-country flight. He reported that the airplane was full of fuel before he departed on the first leg of the trip, the duration of which he did not provide. The pilot also reported that he was concerned with the weather at his destination and did not add fuel before departing on the accident flight to expedite his return. He had planned the flight at 7,000 ft mean sea level and felt there was enough fuel onboard at that altitude. After about 1 hour of flight, an air traffic controller directed the pilot to climb to 9,000 ft and rerouted the flight. The pilot stated he became concerned with the fuel level at that time due to the climb and change in wind, but he chose to continue to his destination. About 30 minutes later and 20 miles short of the intended destination, the engine lost all power due to fuel exhaustion, and the pilot subsequently conducted an emergency landing in a field. At no time during the flight did the pilot express his concerns about the lack of fuel onboard to the controller, request a diversion to a closer airport, or declare an emergency.
The elevator sustained substantial damage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot's improper fuel planning and decision to not divert to a closer airport when the planned flight profile changed, which resulted in a total loss of engine power due to fuel exhaustion.

- 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.
