Accident Overview
A pilot, who is also a certificated aircraft mechanic, was conducting the first postmaintenance check flight after rebuilding the airplane. As the airplane began to fly off the runway, the pilot pulled aft on the yoke, and the airplane nosed over.
Investigation Findings
Postaccident inspection revealed that the elevator cables had been connected backwards. The pilot stated to the NTSB investigator-in-charge that he had purchased the airplane as a project and rebuilt it. He acknowledged that he hooked up the elevator cables in reverse and did not recognize the error during his inspection. He also noted that he did not have anyone else inspect his work.
Probable Cause
The probable cause of the accident is the pilot's incorrect installation of the elevator cables in a reversed configuration, which was not detected during his post-rebuild inspection.
Additional Information
The pilot's dual role as both the aircraft mechanic and the pilot conducting the check flight underscores the importance of thorough inspections following maintenance work.
