What happened
The incident occurred following a landing where the aircraft's left float struck a rock and became lodged. While the pilot was standing on the float, he attempted to dislodge the airplane. During this effort, he slipped and fell into the turning propeller.
The investigation
Investigations relied on statements from the pilot and witnesses located on the riverbank. They confirmed that the left float had become stuck on a rock during the post-landing taxi phase. The primary mechanical interaction involved the pilot falling into the active propeller while attempting to free the aircraft.
Findings
The pilot, identified as an orthopedic surgeon, sustained significant injuries to his left hand. Specifically, he lost three fingers from that hand due to the contact with the rotating blades. The accident was caused by the pilot falling into the turning propeller while trying to free the aircraft.
