Aircraft Accident/Incident Report

Lake Powell, Utah 84533
Thursday, October 20, 2005 16:30 MDT

NTSB Narrative Summary Released at Completion of Accident

According to the pilot, he was making a water takeoff from a finger of a lake that extended into a narrow canyon. During the takeoff run, he was almost on the step when the right float struck a submerged object. He aborted the takeoff by reducing power. The airplane drifted to the right, and the right wingtip contacted the canyon wall. The airplane pivoted to the right, the right float contacted the canyon wall, and the airplane came to a stop. The right wing sustained structural damage.

NTSB Probable Cause Narrative

The pilot's failure to maintain clearance from terrain during an aborted water takeoff run which resulted in the airplane colliding with a canyon wall. A contributing factor was the submerged object that the airplane struck during the takeoff run.
