This term is defined as "engine shutdown without delay"
What is Emergency Shutdown?
100
EMERGENCY SHUTDOWN
Throttle - Close. Fuel Valve Switch - OFF. BATT Switch - OFF as desired. (Before turning the battery switch to off during an in-flight emergency, the pilot should conisder a MAYDAY call, selecting emergency on the transponder and the possible effects of total electrical failure.)
100
Emergency Equipment
Fire extinguisher - between pilot and copilot stations First Aid Kit - in one of the pouches by the passenger seat Emergency Locator Transmitter (ELT) - See Chp 2
100
Engine Restart - During Flight NOTE
Do not attempt air start above 12,000 feet MSL (TURB OUT TEMP rises too fast to control)
100
Engine Overspeed
right yaw, rapid increase in rotor and engine RPM, increase in rotor and engine noise
200
LAND AS SOON AS POSSIBLE
Land without delay to the nearest suitable area (ie open field) in which a safe approach and landing is reasonably assured. (The primary consideration is to ensure the survival of the occupants)
200
Engine Compressor Stall (EP Steps)
Collective - Reduce Engine Anti-Ice and Heater switches - OFF Land as soon as possible
200
Engine Compressor Stall
Sharp rumble or series of loud sharp reports, severe engine vibration, rapid rise in TOT
300
Engine Failure at a Hover & at Low Altitude/Low Airspeed or Cruise
Hover: Autorotate Emer Shutdown - (Accomplish after landing) Low Alt/Low AS: Autorotate Emer Shutdown - (Accomplish during descent if time permits)
300
Emergency Exits/Entrance
Emergency exit or entrance is through either cabin or crew door. If the door(s) will not open, the windows should pop out if pressure is applied to the outer edges of the window. If the window will not pop out, kick out the plexiglass to exit the aircraft.
300
Partial or Complete Power Loss
The indications of an engine malfunction, either a partial or a complete power loss are: left yaw, drop in engine RPM, drop in rotor RPM, low RPM audio alarm, illumination of the LOW ROTOR RPM caution light, and change in engine noise. If the power loss is total, the ENGINE OUT light will activate and an intermittent tone will be heard.
400
LAND AS SOON AS PRACTICABLE
The landing site and duration of the flight are at the discretion of the pilot. Estended flight beyond the nearest approved landing area is not recommended. (The primary consideration is the urgency of the emergency.)
400
Engine Restart - During Flight
Throttle - Close Fuel Valve Switch - On Attempt Start Land as soon as possible
400
Hot Start (Def & EP Steps)
During startup or shutdown, if TOT limits are exceeded, or it becomes apparent the TOT limits may be exceeded, proceed as follows: Starter button - Press and hold until TURB OUT TEMP is less than 200 C Throttle - Closed FUEL VALVE switch - OFF Complete shutdown.
400
Partial or Complete Power Loss WARNING
Do not respond to the RPM warning system by entering autorotation and reducing the throttle without first confirming engine malfunction by one or more of the other indications. Normal indications signify that the engine is functioning properly that there is a tachometer generator failure or an open circuit to the warning system, rather than an actual engine malfunction.
500
Engine Overspeed
Collective - Increase (to load the rotor and sustain engine/rotor RPM below the maximum operating limit) Throttle - Adjust (until normal operating RPM is attained) Land as soon as possible (perform a power on approach and landing by controlling the RPM manually with the throttle) If RPM cannot be controlled by throttle adjustment: Autorotate (When over a safe landing area) Emer Shutdown (Accomplish during descent if time permits)
500
Engine Underspeed (EP Steps)
If an engine underspeed occurs, the collective must be adjusted downward to maintain rotor within RPM limits. If powered flight with rotor in the green can be accomplished: Land as soon as possible (in an area that will permit a run on landing) An engine underspeed below 90% results in rotor RPM decay below minimum safe limits. Should this occur: Autorotate Emer Shutdown (Accomplish during the descent if time permits)
