Engine Failure

"Engine Failure on Take-Off"

When a motor fails, particularly on take-off, the action to be taken by the Pilot must vary somewhat depending upon the situation. (Such as terrain, weather, traffic, load, etc.) Much depends on the judgment and discretion of the Pilot. The value of an engine failure procedure lies in the fact that it prepares the Pilot in advance of an emergency as to what must be done. The execution of these items can then be done smoothly and efficiently thus eliminating the need for hurried, unpremeditated moves which constitute the greatest hazard of any emergency operation.

There is sufficient power available in three engines to climb the B-24 and all of this power should be used. When sufficient altitude has been gained to insure safety, reduce power to amount required to safely sustain flight and proceed in a normal manner.

Failure of Engines No. 1, 2 or 4:

  1. Maintain 135 MPH indicated airspeed
  2. Trim ship - rudder first to relieve yaw, aileron second for as good "hands off" condition as possible
  3. Start gear up
  4. Feather dead engine (mixture - "IDLE CUT-OFF;" fuel booster - "OFF;" ignition - "OFF;" cowl flap - "CLOSED")
  5. Power as necessary to clear obstruction
  6. Request emergency landing clearance
  7. When gear is up, raise wing flaps by small amounts (3° to 4° at a time). (Ship will handle better if 5° to 10° of flap is retained at low speeds.)
  8. Jettison overload: this should not be necessary under most conditions and is left to the discretion of the Pilot.
  9. Line up for landing, avoiding any violent maneuvers doing so. NOTE: Engineer should be sent aft to ascertain whether necessary to close fuel valve to dead engine (broken fuel line, etc.)

Failure of Engine No. 3:

  1. Same as in the case of Engines No. 1, 2 or 4, except that hydraulic pump is located on Engine No. 3.
  2. Be certain auxiliary hydraulic pump is on. Star valve on open center system open (engineer)

    If already on instruments, or it becomes necessary to go on instruments immediately after take-off:

  3. Vacuum pumps are on Engines No. 1 and 2, therefore, selector valve must be turned to live engine to keep flight instruments in operation (Engineer)
  4. If on Automatic Pilot, turn it off and fly manually
