LEONARDTOWN, MD, USA
N24463
TAYLORCRAFT BC-65
TO START THE ENG, THE PLT CHOCKED THE LEFT WHEEL & HAND PROPPED THE ACFT WITH THE THROTTLE SET AT IDLE. HOWEVER, AFTER THE ENG STARTED, ITS RPM WENT ABOVE IDLE & THE ACFT JUMPED THE CHOCK. SUBSEQUENTLY, IT COLLIDED WITH A PARKED ACFT & A RWY LIGHT BEFORE THE PLT CAUGHT THE PLANE & SHUT DOWN THE ENG. HE HAD PERFORMED MAINTENANCE ON THE ENG EARLIER THAT DAY & HAD IMPROPERLY SECURED THE THROTTLE CLAMP, WHICH ALLOWED THE THROTTLE CABLE TO SLIP TO A HIGHER RPM SETTING.
INADEQUATE PREFLIGHT PLANNING/PREPARATION BY THE PILOT BY NOT ASSURING THAT THE ACFT WAS PROPERLY SECURED, OR THAT SOMEONE WAS AT THE CONTROLS WHILE HE WAS HAND PROPPING THE ENGINE. A RELATED FACTOR WAS THE PILOT'S IMPROPER ADJUSTMENT OF THE THROTTLE CABLE.
