NTSB Narrative Summary Released at Completion of Accident

THE SINGLE ENGINED AIRPLANE WAS OPERATING ON AN IFR FLIGHT PLAN AND CLIMBING THROUGH CLOUDS SHORTLY AFTER TAKEOFF. A WITNESS HEARD AN AIRPLANE'S ENGINE POWER SURGING AND OBSERVED A BRIGHT FLASH AT GROUND LEVEL SHORTLY AFTERWARDS. ANOTHER WITNESS OBSERVED THE AIRPLANE DESCENDING AND FLY PAST HIM JUST BEFORE SEEING A BRIGHT FLASH AND HEARING THE CRASH. THE AIRPLANE STRUCK AN ELECTRICAL POWERLINE AND TREE BEFORE COLLIDING WITH THE GROUND AND SLIDING TO A STOP. AN ON-SCENE INVESTIGATION REVEALED WATER IN THE CARBURETOR FLOAT AND ACCELERATOR PUMP CHAMBERS. THE COMMUTATOR OF THE TURN AND SLIP INDICATOR'S ELECTRIC MOTOR WAS FOUND WITH A GROOVE WORN AROUND IT AND A BLACK POWDERY SUBSTANCE PERMEATING THE INTERNAL MECHANISM OF THE INSTRUMENT. DURING AN INTERVIEW WITH THE PILOT, HE STATED THAT HE HAD TAKEN A FUEL SAMPLE FROM EACH FUEL SUMP ON THE AIRPLANE DURING HIS PRE-FLIGHT WALK AROUND INSPECTION. THE PILOT WAS UNABLE TO RECALL THE EVENTS WHICH TOOK PLACE AFTER ENTERING THE CLOUDS.
