The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings

The student pilot’s inadequate inflight navigation and the flight instructors delayed remedial action which resulted in a collision with trees.

WENATCHEE, Washington — A plane carrying two people crashed into Bomber Bowl on Mission Ridge Sunday afternoon. Both survived without injury.

The plane took off from Boeing Field in Seattle and the report of the crash came in about 5 p.m., said Chelan County Sheriff’s Office Sgt. Scott Lawrence, who responded to the crash.

The Cessna 172P Skyhawk dropped into the bowl after its pilot apparently became disoriented and flew into the wrong canyon, he said.

The pilot did not have space to maneuver or enough power to get over the mountain, he said. A pilot under instruction and flight instructor had been flying the plane.

The plane was destroyed, he said.

Lawrence said the plane crash was not related to brush fire south of Wenatchee Sunday afternoon.
