Investigator assessment
Analysis narrative
The pilot stated after the third parachute jumper exited the aircraft, he '...continued at reduced power and started to glide down...for landing. As i was starting a long final approach i saw that i would need power to maintain the glide slope. There was no response when i advanced the throttle.' attempts to restart the engine were unsuccessful and the pilot made a forced landing. A post-accident engine run was performed. The FAA inspector stated the engine started normally and ran smoothly during the test. Impact damage to the propeller precluded a full power run-up. Temperature and dew point conditions were favorable for serious carburetor icing at glide power settings.
