Engine Power Loss During Climb
The pilot reported that the airplane was operating normally during engine checks before takeoff. About 10 minutes after departure, while climbing to 2,500 feet above mean sea level, the pilot noticed that the airplane was not gaining altitude and the RPM was dropping. The throttle was at full forward position, and the pilot pulled the carburetor heat on. Subsequently, the oil pressure gauge indicated zero. The airplane continued losing altitude, with the propeller windmilling and the RPM gauge indicating about 1,000 RPM.
Forced Landing
The pilot executed a forced landing to a wooded area, citing the presence of residential homes and the lack of open fields in the vicinity.
Post-Accident Inspection
Inspection of the airplane revealed no engine oil leaks; the oil level was at capacity. Fuel quantity was measured at 2.5 gallons in the right wing tank and 1.3 gallons in the left tank. The system capacity is 12 gallons total, with 12 gallons of usable fuel. No water or contaminants were present in the fuel. With the wings removed, the engine was started and exhibited 30+ psi of oil pressure on the gauge within five seconds at idle power. The inspection disclosed no deficiencies that would have precluded normal engine operation.
