Narrative

ACFT HAS NO GENERATOR/STARTER. PREPARING ACFT FOR START IN ORDER TO MOVE TO PROPER PARKING AREA DESIGNATED FOR GUEST/TRANSIT ACFT. CHOCKED NOSEWHEEL OF VINTAGE 1952 MOONEY-MITE; THROTTLE SET IN IDLE POS WITH FRICTION KNOB TIGHTENED; MAGNETO SWITCH OFF. THEN PRIMED CARB TWICE; SWUNG PROP THROUGH 3-5 TIMES; TURNED KEY ON FOR MAGNETO IGNITION. SWUNG PROP; ENG STARTED TO TURN OVER AND START BUT; AFTER 2 BLADE SWINGS; STOPPED. TURNED OFF IGNITION AND RESET THROTTLE AND TIGHTENED FRICTION KNOB. PRIMED ONCE; SWUNG PROP 3-5 TIMES; TURNED ON IGNITION SWITCH TO BOTH MAGNETOS; THROTTLE STILL IN FLT IDLE AND FRICTION SNUGGED DOWN. HAND SWUNG PROP; ENG CAUGHT AND WENT TO FULL PWR; ACFT JUMPED CHOCKS. I MOVED IN TIME AND AVOIDED PROP; REACHED INTO COCKPIT AS ACFT MOVED QUICKLY FORWARD AND TURNED OFF IGNITION AND RECONFIRMED THROTTLE STILL IN IDLE POS. IN THIS SHORT TIME OF ACFT MOVING FORWARD THE L WINGTIP STRUCK THE R TAIL LIGHT OF A PARKED CAR THEN THE WING SWUNG UP AND OVER THE HOOD KNOCKING OFF THE DRIVER'S REAR VIEW MIRROR. THIS INITIAL IMPACT CAUSED THE ACFT TO SWING L AND CONTINUE FORWARD COMING TO A STOP AGAINST THE NOSE OF A CESSNA 180 WITH THE CESSNA'S EXHAUST STACK PARTIALLY EMBEDDED INTO THE LEADING EDGE SKIN OF THE R WING. THE WOODEN PROP; 1 BLADE; FRACTURED BUT DID NOT SEPARATE AND DID NO DAMAGE TO THE CESSNA. WHAT CAUSED THE ENG TO GO TO FULL PWR IS UNKNOWN AND IS BEING CHKED AT THIS TIME. DAMAGE WAS RELATIVELY LIGHT AND REPAIRABLE. BEST SIT WOULD HAVE HAD ANOTHER PERSON'S HELP IN THE STARTING SEQUENCE FOR BETTER MONITORING AND CTL OF OP WITH THIS TYPE OF VINTAGE ACFT AS WELL AS MOVING IT TO A BETTER STARTING AREA. FORTUNATELY; NO ONE WAS INJURED AND DAMAGE WAS MINIMAL CONSIDERING WHAT COULD HAVE HAPPENED! A VERY STRONG LESSON LEARNED ABOUT SAFETY. THIS HAPPENING TO EVEN A SEASONED PLT; WHO IS A SAFETY OFFICER IN THE MIL AS WELL AS A CH47 MAINT PLT; AND FLYING FOR A MAJOR AIRLINE; AN UNFORTUNATE AND VERY HUMBLING AND SOBERING EXPERIENCE!
