Accident Summary
A student pilot was conducting a flight in a single-engine airplane when, during a descent to the traffic pattern for landing, he experienced difficulty with the propeller governor motor while transitioning from low RPM to high RPM.
Sequence of Events
The airplane was high and fast on final approach, leading the pilot to elect a go-around. During the go-around, the pilot observed that both airspeed and engine RPM began to decrease. He decided to fly a right-hand pattern and return for landing on the same runway. While turning from right base to final, the aircraft was no longer able to maintain altitude and struck a utility pole with its left wing, causing the wing to separate from the fuselage.
Post-Accident Examination
An examination of the propeller system revealed a loose wire (cable) to the propeller governor. No other anomalies were reported.
