NTSB narrative
The pilot was performing aerobatic maneuvers when the airplane's right rudder cable separated. He flew the airplane to an open field, and while at 4,300 feet msl, exited the airplane. Once clear of the airplane, he deployed his parachute. He stated that he observed the airplane enter a descent, and subsequently, impact trees. The pilot landed on a dirt road without further incident. There were no reported ground injuries. Review of photographs taken at the accident site revealed that the rudder control cables displayed extensive corrosion. In addition to the total separation of the right rudder cable as a result of corrosion, other segments of the cable displayed separation of some cable strands. Review of the aircraft's maintenance records revealed that the aircraft underwent its last condition inspection on May 12, 2001, at an aircraft total time of 540.96 hours. The condition inspection was the last entry in the aircraft logbook and it read in part, "inspected and lubed control and cables." At the time of the accident, the airplane had accumulated approximately 18 hours since the last condition inspection.
Probable cause
the mechanic's inadequate inspection which resulted in the undetected corroded rudder cable and its subsequent failure during aerobatic maneuvers.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
