Propeller Governor Failure
If the RPM does not respond to power lever movement or overspeeds,
the most likely cause is a faulty governor or an oil system malfunction.
If moving the power lever is difficult or rough, suspect a power lever
linkage failure and perform the Power Lever Linkage Failure checklist.
Propeller RPM will not increase:
1. Oil Pressure ....................................................................... CHECK
2. Land as soon as practical.
Propeller overspeeds or will not decrease:
1. Power Lever .................................ADJUST (to keep RPM in limits)
2. Airspeed........................................................ REDUCE to 90 KIAS
3. Land as soon as practical.
