NTSB Factual Report

The pilot reported he maintained a higher than normal approach speed due to the gusty wind conditions. He applied flaps just prior to touching down, and the airplane bounced. The pilot reported that when the airplane bounced, he hit the throttle with his knee and did not realize it until he recognized that the airplane was accelerating between brake applications. The airplane continued off the end of the airstrip where it contacted a ditch resulting in substantial damage to the right wing.

NTSB Probable Cause

The pilot's inadvertent movement of the throttle control during landing, which resulted in an increase in power and excursion from the runway.
