  1. High Frequency Vibration
    • 1) ECS - Off
    • If vibrations continue:
    • 2) Land as soon as possible
    • If vibrations cease:
    • 3) Land as soon as practical
  2. Complete Loss of Tail Rotor Thrust
    • In a hover:
    • 1) Twist Grip - Flight idle
    • 2) Cyclic - Eliminate drift
    • 3) Collective - Increase to cushion landing
    • Transition to forward flight or hover/air taxi:
    • 1) Twist Grip - Flight idle
    • 2) Cyclic - Eliminate sideward drift
    • 3) Collective - Increase to cushion landing

    • At altitude:
    • 4) Autorotate

    • If yaw is not controllable:
    • 5) Twist Grip - Flight idle immediately

    • If yaw is controllable:
    • 6) Continue powered flight and set up to a suitable landing area at or above minimum rate of descent autorotation airspeed
    • 7)Autorotate
    • 8) Twist Grip - Rotate to flight idle prior to touchdown
  3.  Mast Bumping
    • 1) Establish positive G load and/or balanced flight as required
    • 2) Land immediately
  4. Ditching: Power On
    • 1) Passengers and Aircrew - Alert
    • 2) Shoulder harness - Locked
    • 3) MAYDAY - Transmit
    • 4) Transponder - Emergency
    • 5) Perform normal approach to taxi 3-5ft above water
    • 6) Doors - Jettison
    • 7) Non-essential personnel - Execute emergency egress
    • 8) Helicopter - move a safe distance away
    • 9) Vertical Landing - Perform
    • 10) Twist Grip - Close
    • 11) Collective - Increase slowly to max pitch
    • 12) Cyclic - Maintain helicopter upright as long as possible
    • 14) Underwater Egress - Execute
  5. Underwater Egress
    • 1) HABD - As required
    • 2) ICS Cords - Disconnect
    • 3) Doors - Jettison
    • 4) Place hand on known reference point
    • 5) Harness - Release
    • 6) Exit helicopter
  6. Ditching: Power Off
    • 1) Autorotate
    • 2) Shoulder Harness - Lock
    • If time and altitude permit:
    • 3) MAYDAY - Transmit
    • 4) Transponder - Emergency
    • 5) Doors - Jettison
    • 6) Underwater Egress - Execute
  7. Engine Restart in Flight
    • 1) Autorotate
    • 2) Starter - Engage
    • 3) Twist Grip - Check full open
    • If light-off does not occur:
    • 4) Twist Grip - Close
    • If light-off occurs:
    • 5) Twist Grip - Full open
    • 6) Land as soon as possible
  8. Main Drive Shaft Failure
    • 1) Autorotate
    • 2) Twist Grip - Adjust to maintain Nf in range
    • (Tail rotor effectiveness may be lost if Nf goes below 80%)
    • When on deck:
    • 3) Emergency Shutdown - Complete
  9. Engine Overspeed
    • 1) Twist Grip - Reduce to maintain Nf/Nr in operating range
    • 2) Collective/Twist Grip - Coordinate
    • 3) LAnd as soon as possible
  10. Engine Underspeed
    • 1) Collective - Lower as required to maintain a minimum of 90% Nr
    • 2) Twist Grip - Full open
    • 3) Gov RPM - Full increase

    • If underspeed persists:
    • 4) Check power available with Nr in limits

    • If power is not sufficient:
    • 5) Autorotate

    • If sufficient power is available:
    • 6) Land as soon as possible
  11. Compressor Stall
    • 1) Collective - Reduce
    • 2) Engine Anti-ice Switch - ON
    • 3) Cabin Heat Valve - ON

    • If compressor stall persists and aircraft is uncontrollable:
    • 4) Autorotate
    • 5) Twist Grip - Flight idle

    • If compressor stall clears and aircraft is controllable:
    • 6) Land as soon as possible
