Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

Poor and improper maintenance which resulted in the carburetor venturi being blocked by the duct tape. Contributing to the accident was the soft terrain on which the forced landing was made.

Analysis

Accident airplane was being used for sport parachute activity when engine failed during the initial climb of a jump sortie. The PIC instructed his four skydiver passengers to assume a crash position and accomplished an off airport landing in a soft field. During the landing roll the nose landing gear collapsed. Post accident examination of the engine revealed a piece of duct tape obstructing the carburetor venturi restricting airflow to the engine.
