The 800 hour pilot reported to the NTSB investigator-in-charge that shortly after a normal takeoff, the engine sputtered and coughed during the initial takeoff climb. The engine then operated normally for about 10 seconds, then it sputtered and backfired for another 15 seconds, until the engine stopped developing power. During the landing roll, the main landing gear dug into the soft dirt and the airplane nosed over coming to rest in the inverted position. A detailed examination of the engine induction air system revealed evidence of a previous engine induction system fire. The rubber induction air sleeve (P/N: A1535-13) was found charred and burned. The inspector stated that the restriction on airflow to the carburetor during a period of high power demand due to the collapsing of the air induction sleeve resulted in the loss of engine power. The airplane's total time in service was reported as 3,572 hours. The airplane had accumulated 7 hours since its last annual inspection.
Probable Cause: The loss of engine power due to the collapsed of the engine induction air ducting. Factors were the inadequate maintenance inspection and the lack of suitable terrain for the pilot to execute the forced landing.
