NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

During a 50 hour maintenance inspection, an airframe and powerplant mechanic discovered that the airplane's firewall was substantially damaged. The operator was not able to determine when the accident flight occurred or the pilot responsible.

The airplane's last maintenance inspection occurred about three months prior to the discovery. Numerous pilots flew the airplane during that period, none of which reported an event that would result in damage to the airplane.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
Firewall damage reported by maintenance personnel that occurred during an unknown phase of flight, because the accident flight and pilot could not be determined.
