Procedure
Respond to oil pressure indicator warning and engine speed limitation
1. Note that the oil pressure indicator has gone off and the buzzer has sounded — the engine protection system is now limiting engine speed. WARNING: Do not ignore this warning. Continued operation with low oil pressure can cause severe engine damage. 2. Allow engine speed to decrease automatically if at cruising speed. 3. Check the engine oil level immediately. 4. If oil level is adequate, inspect the engine lubrication system for a potential fault.
