What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Prior to the accident take-off, the accident pilot landed on williams lake and let a front seat passenger out of the aircraft then took off again to do some water landings. While maneuvering to perform a full-stop water landing he performed a 180 degree right-hand turn to final at about 300-400'AGL, he applied left rudder and aileron to stop the right turn. The left rudder pedal seemed blocked and wouldn't move. The aircraft then entered a tight right hand spiral and impacted a tree, and then fell to the ground. Investigation discovered that the front seat passenger did not properly secure the seat belt causing the seat belt to become jammed under the left rudder paddle, making it impossible to apply left rudder pedal.
