-
Governor Failure: Low Side
- Symptoms: same as engine failure but after a few seconds, NG stabilizes at <70%.
- Establish auto at 65 kts.
- Advance fuel control (results in Ng & T4 rise)
- Maintain 70% Ng.
- Increase fuel flow to ~380 rpm Nr.
- Trim collective & fuel flow to hold level flight at this rotor speed.
-
Governor Failure: Surging
- Symptoms: hunting of the rpm, torque, & T4 with jerks in the yaw axis.
- Change collective setting.
- If surging persists & fuel pressure and engine oil pressure are normal, reduce fuel flow slightly (to leave governed range).
- If surging still persists: Land ASAPossible and shut down.
-
NR Indicator Failure
- Keep torque >10%.
- NF will indicate NR.
- Land ASAPossible.
-
Free Turbine (NF or NTL) indicator failure
- Check that NR is still stable with slow torque changes.
- Continue flight (!?).
-
Governor Failure: High Side
- Symptoms: NG, T4, NR increase.
- Do NOT reduce collective.
- Reduce fuel flow until NR in green.
- Continue flight without Governor.
- (a decrease in collective = increase in rotor RPM = must increase fuel control, etc.)
- Minimize power changes on approach.
-
Delta NG Indicator Failure
- Watch Torque.
- Limit T4 to:
- 730 degrees if <15 degrees C OAT.
