Incident Overview
A pilot reported that after the third parachute jumper exited the aircraft, he continued at reduced power and began a glide descent for landing. While starting a long final approach, he realized he needed power to maintain the glide slope. When he advanced the throttle, there was no response. Attempts to restart the engine were unsuccessful, and the pilot executed a forced landing.
Post-Accident Examination
Following the incident, an engine run was performed under the supervision of an FAA inspector. The inspector stated that the engine started normally and ran smoothly during the test. However, impact damage to the propeller prevented a full power run-up.
Environmental Conditions
At the time of the event, temperature and dew point conditions were favorable for serious carburetor icing at glide power settings. This may have contributed to the loss of engine power, though the source does not explicitly assign causation.
