Bell 407 Emergency Procedures - Full Reference

All 14 procedures with immediate action steps, in full.

Engine Failure - Hovering (RFM 3-3-A-1)

Immediate actions · 6 steps

  1. 1
    Maintain heading and attitude control
  2. 2
    CollectiveADJUST to control NR and rate of descent
  3. 3
    CollectiveINCREASE prior to ground contact to cushion landing
  4. 4
    Land
  5. 5
    Shut down helicopter
  6. 6
    Noteamplitude of collective movement is a function of height above ground; any forward airspeed will aid the ability to cushion the landing

Engine Failure - In Flight (RFM 3-3-A-2)

Immediate actions · 8 steps

  1. 1
    Maintain heading and attitude control
  2. 2
    CollectiveADJUST as required to maintain 85 to 107 percent NR
  3. 3
    CyclicADJUST to obtain desired autorotative airspeed (55 KIAS min ROD, 80 KIAS max glide, 100 KIAS max)
  4. 4
    Attempt engine restart if ample altitude remains
  5. 5
    FUEL VALVE switchOFF
  6. 6
    At low altitudethrottle CLOSED, then flare to lose airspeed
  7. 7
    Apply collective as flare effect decreases to reduce forward speed and cushion the landing
  8. 8
    On ground contactreduce collective smoothly while maintaining cyclic neutral or centered

Engine Restart In Flight - Automatic Mode (RFM 3-3-B-1)

Immediate actions · 10 steps

  1. 1
    CollectiveADJUST to maintain 85 to 107 percent NR
  2. 2
    AIRSPEEDADJUST as desired (55 KIAS minimum rate of descent allows more time for the restart)
  3. 3
    FUEL VALVE switchON
  4. 4
    ThrottleCUTOFF
  5. 5
    START switchHOLD to start position (latches after throttle is placed to idle)
  6. 6
    NGbetween 12 and 50 percent, then throttle to IDLE
  7. 7
    MGTMONITOR
  8. 8
    ThrottleADVANCE smoothly to FLY detent position
  9. 9
    If unsuccessfulthrottle CLOSED, FUEL VALVE OFF, accomplish autorotative descent and landing
  10. 10
    Cautionif the cause of failure is obviously mechanical (abnormal metallic or grinding sounds) do NOT attempt a restart

Complete Loss of Tail Rotor Thrust (RFM 3-5-A)

Immediate actions · 7 steps

  1. 1
    HoveringCLOSE THROTTLE and perform a hovering autorotation landing; a slight rotation can be expected on touchdown
  2. 2
    In flightREDUCE THROTTLE to idle, immediately enter autorotation
  3. 3
    In flightmaintain a minimum AIRSPEED of 55 KIAS during descent
  4. 4
    During final stages of approach execute a mild flare, making sure all power to the rotor is off
  5. 5
    Maintain a slight flare and smoothly use collective for a soft, slightly nose-high landing
  6. 6
    Landing on the aft portion of the skids will tend to correct side drift
  7. 7
    Cautionin a run-on landing after touching down, do NOT use cyclic to reduce forward speed

  4. 4
    For extended flightset a comfortable AIRSPEED up to 120 KIAS to minimize control forces
  5. 5
    Land as soon as practical
  6. 6
    A run-on landing at effective translational lift speed (approximately 15 knots) is recommended
