- 3. Feather button -- Push. (FE)
Fire of Unknown Origin
- 1. Alert crew, activate fire bill -- Alerted. (CP,TC)
- 2. Cabin exhaust fan -- OFF. (FE)
- If cabin altitude exceeds 10,000 feet, the flight station SHALL:
- 1. Don smoke masks.
- 2. Alert Crew.
- In the event of a scissor switch failure and loss of associated aircraft system functions, perform the following steps:
- 1. Pressurization ground check switch -- TEST.(FE)
- 2. Ground air-conditioning switch -- ON. (FE)
Emergency Depressurization Procedure
- 1. AUX VENT -- OPEN. (FE)
- 2. OUTFLOW VALVE -- OPEN. (FE)
- 3. EDCs -- DUMP. (FE)
- 4. AUX VENT -- Close at 1-inch differential. (FE)
- Without electrical power available:
- 5. FREE-FALL CHUTE -- Open. (OBS)
- 1. Autopilot -- Disengaged. (P)
- 2. Power levers -- FLIGHT IDLE. (P)
- 3. Landing gear lever -- As required. (CP)
- 4. Airspeed-- As required. (P)
- 5. Pressurization -- As required. (FE)
Note: Flight station shall verify obstacle clearance and altimeter setting.
1. Alert crew time to impact -- Alerted. (CP)
- 1. Request ground firefighting equipment. (CP)
- 2. Stop the aircraft. (P)
Engine Fire on the Ground
- 1. Emergency chutdown handle -- Pull. (FE)
- 2. HRD -- Discharged. (P, FE)
Emergency Shutdown Procedure
- 1. Emergency shutdown handle (on pilot command) -- Pull. (FE)
- 2. HRD (fire only) -- Discharged. (P,FE)
Shifting to Boost Off
- 1. Disconnect the autopilot.
- 2. Attempt to obtain a safe altitude.
- 3. Set Condition V.
- W.If the trim tabs have been moved several degrees away from the normal trim position, the aircraft may react violently when shifting boost off.
- 4. Trim tab setting -- Check for normal position.
- If abnormal force is still present:
- 5. Booster shift handle -- Pull.
- W - Be prepared to immediately return to boosted flight control if operation of the aircraft is diminished.
- - Avoid force on the affected controls while shifting to prevent a sudden change in control surface position when the boosters are turned on or off.
- 1. If rpm at or above 115 percent -- Reduce airspeed (150 KIAS minimum) and perform Operation with a Pitchlocked Propeller procedure, paragraph 15.12.2. (P,FE)
- 2. If rpm below 115 percent -- Smoothly advance affected power lever and increase TAS, noting engine indications. (P,FE)
Propeller Fails to Feather
- 1. Feather button -- In.
- W - If propeller feathered at step 1, ensure emergency shutdown wiper switch circuit breakers are set.
- 2. PCO -- Press.
- 3. Alternate bus (propellers 1 and 4) -- Select.
- 4. PROP FEATHER circuit breakers -- Check in.
- 5. Airspeed -- Decrease toward 150 KIAS.
- N: Subsequent airspeed selection should be based on aircraft gross weight and controllability.
- If feather button light remains on:
- 6. PROP FEATHER CONT circuit breaker -- Pull.
- N: If the propeller remains in an overspeed condition, refer to Operation with a Pitchlocked Propeller procedure, paragraph 15.12.2.
Flight with a Cracked Front Windshield
- 1. Turn off heat of affected panels.
- 2. Helmets on, visors down. (P,CP,FE)
Loss of All Airspeed Indication
1. Check pitot heat -- ON. (FE)
Out of Controlled Flight, Spiral and Spin Recovery
- 1. Power levers -- FLIGHT IDLE. (P)
- 2. Flight controls -- Neutralize. (P)
- 3. Airspeed, AOA, turn needle -- Check. (P)
- N: A spiral is often mistaken for a spin. Anti-spin controls may not be effective in arresting a spiral and may aggravate the situation. The indications of a spiral are stalled AOA, pegged turn needle, and airspeed increasing. The indications of a spin are stalled AOA, pegged turn needle and stabilized airspeed.If in a spin:
- 4. Rudder -- Full opposite turn needle. (P)
- As soon as yawing motion stops:
- 5. Controls Neutralize. (P)
- 6. Unusual attitude -- Recover. (P)
Windshear Escape Procedure
- 1. Max power -- Set. (P,FE)
- 2. Pitch attitude -- 10° up. (P)
- W Any attempt to recover loss of airspeed by decreasing pitch or allowing the aircraft nose to fall through is not recommended.
- 3. Landing Gear -- UP. (P,CP)
- 4. FLAPS -- Do not change until out of windshear. (P)
Split Flap Procedures
- 1. If uncontrollable, reset the flap handle to the previous position.
- 2. If controllable, land with the flap handle in the selected position.
