Incident Overview
A pilot encountered difficulties with the aircraft's directional gyro during flight, experiencing excessive precession that caused large deviations from the planned flight path. Despite recognizing the instrument's inaccuracy, the pilot continued to rely on it for some heading information. The aircraft subsequently continued to wander off course until fuel exhaustion occurred.
Forced Landing
With the engine out of fuel, the pilot was forced to land the aircraft on a small ranch road. The landing was conducted during the hours of darkness, with the aid of the aircraft's landing light. No further details about the outcome or damage were provided.
Inflight Gyro Issues
The directional gyro exhibited excessive precession, meaning its indication drifted significantly from the actual heading. This led to the pilot losing accurate situational awareness of direction, resulting in the aircraft straying from the intended route over an extended period.
