Aircraft Accident/Incident Report

Palo Alto, California 94303
Saturday, July 15, 2000 11:00 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilots of a Beech (Baron) and a Cessna planned to depart using runway 31, and they taxied toward the runway's engine run-up area. Upon arrival, the Baron pilot found the area fully occupied by six other airplanes, so he held short. The Cessna pilot stopped in trail behind the Baron. After a few minutes, an airplane vacated the run-up area, and the Baron pilot applied engine power to reposition his airplane in the run-up area. The Cessna pilot attempted to pass the Baron by proceeding between the Baron's right wing and another airplane, to the Cessna's right side. The Cessna pilot indicated that he misjudged his clearance, and the leading edge of his left wing impacted the rear of the Baron's rotating propeller blades.

NTSB Probable Cause Narrative

The Cessna pilot's inadequate visual lookout and misjudged distance to a standing Beech while taxiing for takeoff.
