On June 7, 1992, a Beech V35B (registration N9035V) operated by Lane, Jeffrey G. was involved in an aviation accident near Panguitch, UT. Investigators recorded the probable cause as: The grounding wires (P leads), where they enter the magneto housing, had shorted against the retaining nut. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a base turn to runway 19, a pilot experienced total engine power loss and performed a forced landing on rough terrain. Post-crash examination found a short in the magneto P-lead grounding wires.
Accident Details
While turning from base leg to final approach for runway 19 at Panguitch Municipal Airport, the pilot encountered a complete loss of engine power. Unable to reach the runway, the pilot executed a forced landing on rough terrain short of the runway threshold. During the landing roll, the nose wheel strut experienced overload forces and separated from the aircraft.
Examination Findings
Post-crash examination and testing of the ignition system revealed that the grounding wires, known as P leads, had shorted against the retaining nut at the point where they enter the magneto housing. This short circuit prevented proper ignition operation, leading to the power loss.
Probable cause
The grounding wires (P leads), where they enter the magneto housing, had shorted against the retaining nut.
