- 2Throttle - REDUCE until normal operating RPM is attained, then continue with manual throttle control
- 3If throttle reduction does not reduce RPMEMER GOV OPNS
- 4Warning - land even if manual throttle corrects the overspeed, since there is a chance of impending engine failure from debris generated by the initial N2 failure
- 1Land as soon as possible
- 2EMER SHUTDOWN after landing

- 4Note - if transmission oil pressure drops to zero PSI, a valid cross reference cannot be made with the oil temperature indicators
- 1Autorotate
- 2EMER SHUTDOWN
- 3Indications - left yaw, increase in engine RPM, decrease in rotor RPM, low RPM audio alarm, RPM warning light
- 1CollectiveREDUCE
- 2DE-ICE and BLEED AIR switchesOFF
- 3Land as soon as possible
- 4Indications - sharp rumble or loud sharp reports, severe engine vibration, rapid rise in EGT
- 1Avoid abrupt flight control inputs - they cause excessive main rotor flapping which may result in mast bumping
- 2Intentional flight below +0.5 G is prohibited
- 3Avoid abrupt forward cyclic inputsthe helicopter may roll right simultaneously
- 4If bumping occurs during startup or shutdownreposition controls
- 5Intentional maneuvers beyond +/-30 degrees pitch or +/-60 degrees roll are prohibited
