DUAL ENGINE FAILURE
- Autorotate
SINGLE ENGINE FAILURE
- Achieve safe single engine airspeed (if possible)
- External cargo/stores - Jettison (if required)
FIRES: APU/ELECTRICAL/ENGINE
IF ENG EMER OFF Handle/APU fire T-handle illuminates in flight:
- Achieve safe single engine airspeed (if possible)
- ENG POWER CONT lever - OFF
- ENG EMER OFF Handle/APU fire T-handle - Pull (as required)
- FIRE EXTINGH switch - MAIN/RESERVE as required
IF AN ELECTRICAL FIRE IS PRESENT:
- BATT and GENERATORS switches - OFF
ENGINE CONTROL MALFUNCTION - (DEC/EDECU) LOW SIDE FAILURE
If % RPM R continues to decrease and single engine flight is not possible:
- ENG POWER CONT lever (low % TRQ/TGT engine) - LOCKOUT (Maintain % TRQ approximately 10% below the other engine)
STABILATOR UNCOMMANDED NOSE DOWN PITCH ATTITUDE CHANGE
If an uncommanded nose down put h attitude occurs:
- Cyclic mounted stabilator slew-up switch - Adjust (as required to arrest nose down pitch rate)
FLIGHT CONTROL/ROTOR SYSTEM VIBRATIONS OR MALFUNCTIONS ON GROUND
- ENG POWER CONT levers - OFF
- ENG FUEL SYS selectors - OFF
- FUEL BOOST PUMP switches - OFF
LIGHTNING STRIKE
- ENG POWER CONT levers - Adjust (as required to control engine % RPM and % RPM R)
LOSS OF TAIL ROTOR CONTROL
If during cruise flight a right yaw becomes uncontrollable:
- AUTOROTATE - Maintain airspeed at or above 80 KIAS
- ENG POWER CONT LEVERS - OFF (during deceleration when intended point of landing is assured)
If at low airspeed or hover a right yaw becomes uncontrollable:
- Collective - Reduce
- ENG POWER CONT levers - OFF (5 -10 feet above touchdown)
If an uncontrolled left yaw develops during low airspeed or hover:
- ENG POWER CONT levers - Retard
- Collective - Increase (% RPM R will decrease)
- ENG POWER CONT levers - OFF (5 to 10 feet above touchdown)
- Collective - Adjust for landing
HYDRAULIC PUMP NO BACK-UP PUMP #1
- BACK-UP HYD PUMP switch - ON
TAIL RTR SERVO #1 AND BACK-UP ON DOES NOT APPEAR
- TAIL SERVO switch - BACK-UP
