NTSB narrative
The private pilot estimated that he departed on the 10-minute, 16-mile, local flight with one fuel tank about one-half full and the other tank about one-quarter full; he did not recall which tank he had the fuel selector positioned to during takeoff. During descent for landing, the pilot observed the engine rpm decrease to between 500 and 600 rpm, at which time he declared an emergency. The pilot switched fuel tanks but did not remember which tank he selected or whether the engine lost total power. The pilot made a forced landing on the roof of an industrial office building.
During examination of the airplane after it was recovered from the roof of the building, about 7.5 gallons of fuel was drained from the left wing, and about 1 quart of fuel was drained from the right wing; no visible contamination was observed. Additionally, the fuel selector was selected to the right tank position. Other than the absence of fuel in the right tank, examination of the airframe and engine revealed no anomalies that would have precluded normal engine operation. Further, the lack of rotational damage to the propeller was consistent with a loss of engine power before impact. While atmospheric conditions at the time of the accident were conducive to carburetor ice, the physical evidence supports the position that total loss of engine power was due to fuel starvation.
Probable cause
The pilot's mismanagement of the available fuel, which resulted in a total loss of engine power due to fuel starvation.

- 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, coordinates. 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.
