2. Land as soon as practical.
Propeller overspeeds or will not decrease:
1. Power Lever ................................. ADJUST (to keep RPM in limits)

Amplification
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.
