MILLBURY, OH, USA

Aircraft #1

N43416

TAYLORCRAFT BC12D

Analysis

BEFORE THE FLIGHT, A STUDENT PILOT INQUIRED IF HE COULD ACCOMPANY THE PILOT ON THE FLIGHT, AND THE PILOT CONSENTED. THE PILOT ADJUSTED THE THROTTLE AND BEGAN TO START THE ENGINE BY HAND-PROPPING IT. MEANWHILE, THE PASSENGER/STUDENT PILOT BOARDED THE TAYLORCRAFT. THE ENGINE STARTED, THE PLANE BEGAN MOVING FORWARD, AND THE PILOT ATTEMPTED TO ARREST ITS MOVEMENT BY GRABBING THE LEFT WING STRUT. THE PLANE THEN PIVOTED AROUND THE PILOT AND COLLIDED WITH A PARKED AIRCRAFT. AN INVESTIGATION REVEALED THE THROTTLE WAS EASY TO MOVE. THE PILOT AND AN FAA INSPECTOR CONCLUDED THAT THE PASSENGER/STUDENT PILOT MUST HAVE 'BUMPED' THE THROTTLE AS HE ENTERED THE COCKPIT.

Probable Cause and Findings

FAILURE OF THE PILOT TO PROPERLY SECURE THE AIRCRAFT AND/OR ADEQUATELY BRIEF THE PASSENGER (STUDENT PILOT), AND INADVERTENT BUMPING OF THE THROTTLE BY THE PASSENGER.
