## Analysis

THE ACFT COLLIDED WITH THE GROUND DURING TAKEOFF. THE FUEL TANK IN THE RIGHT WING RUPTURED AND THE ACFT BURNED WHILE SLIDING TO A STOP. THE DAY BEFORE THE ACCIDENT THE ACFT WAS WASHED AND THE THRUST REVERSER DOORS WERE POLISHED. AFTER THE SERVICE, THE REVERSER DOORS CIRCUIT BREAKERS WHICH HAD BEEN PULLED WERE NOT RESET. IT WAS COMPANY POLICY TO LEAVE CIRCUIT BREAKERS OUT THAT WERE PULLED DURING SERVICING. PRIOR TO FLT, THE ACFT WAS LOADED AND THE ENGINES STARTED. THE REVERSED UNLOCK LIGHTS ON BOTH REVERSER ANNUNCIATOR PANELS ILLUMINATED. THE PILOT DISCUSSED THE SITUATION WITH THE CO-PLT AND ELECTED TO GO. HE PUSHED THE LIGHT ASSEMBLIES WHICH UNLATCHED THE LIGHT HOUSING AND PUT OUT THE 'UNLOCK' LIGHTS. AFTER TAKEOFF WHILE THE GEAR WAS RETRACTING THE ACFT YAWED RIGHT AND IMPACTED THE GROUND. ALL OCCUPANTS EVACUATED AND AFTER THE FIRE WAS PUT OUT A CESSNA ACFT INVESTIGATOR OBSERVED THE TWO THRUST REVERSER CIRCUIT BREAKERS IN THE 'OUT', OPEN POSITION AND PARTIALLY COVERED BY A FLT CHART. BOTH THRUST REVERSERS WERE DEPLOYED.
