Read the full NTSB narrative

THE PILOT REPORTED IN HIS WRITTEN STATEMENT THAT HE WAS CONDUCTING AN ENGINE RUNUP BECAUSE THE ENGINE WOULD NOT DEVELOP FULL POWER. HE DECIDED TO TAXI DOWN THE RUNWAY WITH NO INTENTION OF TAKING OFF, BUT INADVERTENTLY BECAME AIRBORNE. SHORTLY AFTER THE UNINTENTIONAL TAKEOFF, THE ENGINE LOST PARTIAL POWER, TURNED TO THE RIGHT AND IMPACTED TERRAIN. POST-ACCIDENT EXAMINATION OF THE ENGINE REVEALED EVIDENCE OF HEAT DAMAGE AND ABNORMAL PISTON RING WEAR. THERE WERE SCRAPE MARKINGS ON THE PISTON, PISTON RINGS, AND CYLINDER WALL. THE PILOT STATED THAT HE PERFORMED THE CYLINDER AND RING CHANGE AND WAS NOT AWARE THAT THE CYLINDER AND RING COMBINATION WERE NOT COMPATIBLE.
