The NTSB's narrative final · quoted from the NTSB record
A WITNESS REPORTED TO A FEDERAL AVIATION ADMINISTRATION (FAA) INSPECTOR, THAT SHORTLY AFTER TAKEOFF THE AIRPLANE TURNED BACK TOWARDS THE RUNWAY, THE RIGHT WING DROPPED AND THE AIRPLANE IMPACTED THE GROUND. THE WITNESS FURTHER REPORTED THE AIRPLANE WAS FLYING SLOW AND 'WOULD NOT PICK UP SPEED.' ACCORDING TO THE FAA INSPECTOR, THE RIGHT WING WAS SEPARATED FROM THE AIRPLANE, AND THE WOODEN PROPELLER WAS 'SHATTERED.' THE ENGINE WOULD NOT TURN FREELY DUE TO REAR CASE/MAGNETO DAMAGE; HOWEVER, THE CRANKSHAFT, RODS, AND PISTON ASSEMBLIES HAD CONTINUITY. ACCORDING TO THE PILOT OPERATOR REPORT, THE PILOT HAD THE PROPELLER 'REPITCHED', AND DURING THE ACCIDENT FLIGHT 'IT DID NOT SEEM TO HAVE THE THRUST IT SHOULD HAVE.'
