Ram-Air Turbine Doors Open

If the ram-air turbine (RAT) inlet and exhaust outlet doors open in flight (as indicated by an audible warning in the headset and illumination of the warning light in the landing gear handle if below 10,000 feet), proceed to close the doors to stop the turbine and shut down the emergency hydraulic pump, as follows:

  1. Emergency hydraulic pump lever (RAT) -- Aft (OFF).
  2. If unable to move RAT lever aft: a. Airspeed - Reduce to below 250 knots IAS. b. Ram-air turbine (RAT) circuit breaker — Pull. c. Emergency hydraulic pump lever (RAT) — Aft (OFF).
  3. If no other indication of malfunction exists — Leave ram-air turbine (RAT) circuit breaker out and continue mission.
  4. If unable to close ram-air turbine doors — Burn fuel and land as soon as practical.

    Note

    Flight control system No. 2 should be monitored during RAT operation because of the possibility of exceeding the maximum allowable pressure.
