What happened
The pilot initiated a takeoff sequence from a confined river channel using a float-equipped aircraft. The flight plan included an immediate left turn at the point of lift-off. Upon becoming airborne, the aircraft entered the turn as planned. However, during this maneuver, the right wing made contact with a tree branch protruding into the flight path. The impact caused the aircraft to lose stability and come to rest in an inverted position within the surrounding trees.
The investigation
Post-accident examination revealed that the aircraft ended up upside down among the trees. The pilot provided a statement regarding the sequence of events, confirming the contact with the branch during the initial climb and turn. No mechanical failures were cited as contributing factors to the incident.
Findings
The pilot acknowledged that he may have been overconfident in his ability to execute the takeoff maneuver under the specific conditions presented by the narrow river and surrounding obstacles. The primary factor leading to the accident was the loss of control during the initial phase of flight, specifically due to inadequate clearance during the left turn after lift-off.
