AIRCRAFT WAS DESTROYED.  PILOT RECEIVED MINOR INJURIES (SCRAPES AND BRUISES) TO HIS RIGHT HAND.  PILOT STATED THAT POWER LOSS WAS GRADUAL WITH ENGINE PRODUCING PARTIAL POWER UNTIL ABOUT 2000FT MSL.  PILOT THEN SELECTED LOW PITCH AND SHUT OFF FUEL AND MASTER SWITCH.  ENGINE CONTINUED TO ROTATE UNTIL IMPACT WITH TREES THEN GROUND.  FAA INSPECTORS AT THE ACCIDENT SITE FOUND NOTHING OBVIOUS THAT WOULD CONTRIBUTE TO THE CAUSE OF THE ACCIDENT.  THE AIRCRAFT AND ENGINE WERE RECOVERED AND TRANSPORTED TO FAI BY NORTHLAND AVIATION ON 03/11/2000.  A PARTIAL ENGINE TEARDOWN, WITNESSES BY FAA INSPECTORS, WAS ACCOMPLISHED BY NORTHLAND AVIATION ON 03/13/2000.  FUEL AND LUBRICATION SYSTEMS APPREARED NORMAL EXCEPT FOR METAL CONTAMINATION IN THE OIL.  BOTH INTAKE MANIFOLDS HAD PIECES OF METAL IN THEM WHICH APPEARED TO THE PISTON RING MATERIAL.  SPARK PLUGS FROM ALL CYLINDERS EXCEPT #3 WERE SHORTED AND THE PLUGS FROM #2 PISTON WHERE PHYSICALLY DAMAGED.  #2 AND #1 CYLINDERS WERE REMOVED.  #2 PISTON WAS BADLY ER ODED AND THE CYLINDER WALL WAS ABRADED WITH EVIDENCE OF HEAT DAMAGED. PISTON MATERIAL HAD BEEN COMPACTED INTO THE #2 CYLINDER HEAD.  #1 CYLINDER WAS NORMAL.  NO EXCESSIVE MAIN BEARING OR CRANKSHAFT WEAR WERE NOTED.  #2 CYLINDER AND PISTON ARE BEING SENT TO THE NTSB INVESTIGATOR FOR FURTHER ANALYSIS.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB ANC00LA035](https://openairdocs.org/ntsb/ANC00LA035), Mar 10, 2000: Cessna 207 (N75703), Delta Junction, AK, substantial damage. Probable cause: The disintegration of the number two piston. A factor in this accident was the subsequent metal fouling of the spark plugs, which resulted in total loss of engine power.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
