ADNORMAL START - Baseops



MEMORY ITEMS

ADNORMAL START

1. Condition lever - Fuel Cutoff (note decrease in ITT) (LS)

2. Ignition & Start Switch – Off (LS)

In the event of a hot start:

3. Ignition & Start Switch – Starter only (for remainder of 40-sec starter operation) (LS)

Caution:

Starter use is time limited to 40 seconds on, 60 seconds off, 40 seconds on, 60 seconds off, 40 seconds on, then 30 minutes off

EMERGENCY ENGINE SHUTDOWN ON THE DECK

1. Condition levers – Fuel Cutoff (PF)

2. Firewall valves – Closed (LS)

3. Fire extinguishers – Discharged (For Fire) (PF)

Note:

The engine fire extinguisher is a single shot system with one cylinder for each engine. Do not attempt engine restart until the cause of the fire is determined and corrected.

4. Gang Bar – As required (PF)

5. Evacuate Aircraft – As required

BRAKE FAILURE

1. Maintain directional control with rudder and asymmetrical power

2. Try the other crewmembers brakes

3. Stop the aircraft using propeller reversing to aid in deceleration

BRAKE FIRE

1. Fire fighting assistance – Request (PNF)

2. Stop aircraft (PF)

3. Emergency Shutdown on Deck Checklist – Execute (PF)

Warning:

All crew members are to stay a safe distance away from the aircraft. It is preferable to stay well behind the aircraft. If a wheel explodes because of rapid cooling, the fragments tend to fly out sideways from the wheel. A tire may also explode from the heat of the fire. Do not attempt to fight the fire.

ABORT TAKEOFF

1. Announce intention to abort (PF)

2. Power levers – Idle (PF)

3. Reverse – As required (PF)

4. Brakes – As required (PF)

Note:

Single-engine reversing, if used, must be applied cautiously or loss of directional control may result. Use extreme caution if takeoff surface is not hard and dry. The recommended technique for single-engine reversing is to hold full forward on the yoke, apply aileron into the dead engine, and use rudder as required.

If anticipating insufficient runway remaining:

5. Condition levers – Fuel Cutoff prior to leaving prepared surface (PNF)

After the aircraft stops:

6. Emergency shutdown on the deck checklist – Execute (PF)

RUNAWAY TORQUE PRIOR TO Vr

1. Condition levers – Fuel Cutoff (PNF)

2. Brakes – As required (PF)

Warning:

In the event of runaway torque during take-off roll, bringing the power levers to IDLE will accentuate an uncontrollable yawing tendency and moy result in departure from the runway

ENGINE FAILURE AFTER TAKEOFF

1. Power – Maximum allowable (PF)

2. Airspeed – Vlof or greater (PF)

3. Gear – Up (LS)

4. Propeller (inoperative engine) – Feather or Confirm Autofeather (PF)

5. Airspeed – Vxse (until clearing obstacles, then Vyse) (PF)

6. Flaps – Up (At Vyse) (PF)

7. Emergency Engine Shutdown Checklist – Execute (PF)

Note:

Maximum climb performance can be achieved by raising the failed engine 3-5 degrees up and displacing the balance ball one-half to three-quarters of a ball’s width toward the good engine.

If the autofeather system is being used, retarding either power lever below approximately 90 percent N1 before the feathering sequence is complete will deactivate the autofeather circuit and prevent automatic feathering.

EMERGENCY ENGINE SHUTDOWN

1. Condition Lever – Fuel Cutoff (PF)

2. Propeller Lever – Feather (PF)

Note:

If the right propeller is manually feathered with the PROP SYNC on, the propeller may not go completely into feather, but may rotate at low rpm.

In case of confirmed/suspected fire or visible fluid leak:

3. Firewall valve – Closed (LS)

4. Fire extinguisher – Discharger (For Fire) (PF)

UNCONROLLABLE POWER

1. Emergency Engine Shutdown Checklist – Execute (PF)

WINDMILLING AIRSTART

Caution:

Windmilling airstarts should not be attempted above 20,000 feet or below 140 KIAS. Higher airspeeds and lower altitude will reduce ITT on start

If the windmilling airstart procedure is conducted with a feathered propeller (regardless of propeller lever position) over temperature could occur causing damage to the engine.

1. Power Lever (failed engine) – Idle (PF)

2. Prop Lever (failed engine) – Full Forward (PF)

3. Condition Lever (failed engine) – Fuel Cutoff (PF)

4. Firewall valve – Open (PF)

5. Autoignition – Armed (ignition light on) (PF)

6. Condition Lever (failed engine) – Low Idle (PF)

7. Power – As Required

SMOKE/FIRE OF UNKNOWN ORIGIN

1. Oxygen masks – Don (100 percent) (PF,PNF)

2. Mic Switches – Oxygen Mask (PF,PNF)

Warning:

If smoke and fumes become overwhelming, it may be necessary to remove the smoke by dumping the pressurization.

3. Passenger Oxygen – Deploy (As Required) (PNF)

CABIN FIRE

1. Same as smoke of unknown origin

ENGINE-DRIVEN FUEL PUMP FAILURE

1. Emergency Engine Shutdown Checklist – Execute (PF)

FUEL PRESSURE LIGHT ILLUNINATED

1. Engine Nacelle – Check for fuel leak (PF,PNF)

If fuel is leaking:

2. Emergency Engine Shutdown Checklist – Execute (PF)

PROPELLER FAILURE OR OVERSPEED

1. Prop Lever – Adjust to normal RPM range (PF)

If rpm limits are within normal governing range, continue operation. If normal governing range cannot be maintained, proceed as follows:

Warning:

For prop malfunctions, reversing is not recommended on the affected engine.

Note:

The propeller will continue to provide thrust operating on the overspeed governor or the fuel topping fovernor. Torque is limited to 1,800 ft-lb for sustained operation at 2,080 rpm. The propeller shall be feathered prior to landing.

Should prop rpm be less than 2000, maximum power will not be available for a waveoff.

2. Power Lever (affected engine) – Idle (PF)

3. Prop Lever – Feather (PF)

Note:

If propeller feathers, consider leaving engine running to provide generator power.

4. If propeller fails to feather, Propeller Fails to Feather Checklist – Execute (PF)

EXPLOSIVE DECOMPRESSION

1. Oxygen masks – Don (100 percent) (PF,PNF)

2. Mic Switches – Oxygen Masks (PF,PNF)

3. Passenger Oxygen – Deploy (as required) (PNF)

4. Descend – As Required

Note:

Use of intercom requires headset on, MIC switch to OXYGEN MASK, interphone switch to HOT MIC, and speaker/ phone switch to PHONE.

EMERGENCY DESCENT PROCEDURE

1. Power Levers – Idle (PF)

2. Prop Levers – Full Forward (PF)

3. Flaps – As Required (PF)

4. Landing Gear – As Required (LS)

5. Airspeed – As Required (PF)

Caution:

On completion of emergency descent, do not raise the landing gear above 164 KIAS.

6. Windshield Heat – As Required (LS)

ELECTRIC ELEVATOR TRIM FAILURE

1. Trim disconnect switch – Depress Fully (PF/PNF)

SPINS

1. Power Levers – Idle (PF)

2. Rudder – Full deflection in the opposite direction of turn needle (PF)

3. Control Wheel – Rapidly forward and neutralize ailerons (PF)

4. Rudder – Neutralize after rotation stops (PF)

5. Control Wheel – Execute a smooth pullout (PF)

Warning:

Do not pull out of the resulting dive too abruptly as this could cause excessive wing loads and a possible secondary stall.

SINGLE-ENGINE WAVEOFF/MISSED APPROACH

1. Power – Maximum (PF)

2. Prop Lever – (operating engine) Full Forward (PF)

3. Nose Attitude – Establish a positive rate of climb (PF)

4. Gear – Up (LS)

5. Airspeed – As Required (Vxse or Vyse) (PF)

Note:

Steps 1 through 4 are to be accomplished simultaneously in order to ensure a positive rate of climb is established at the required airspeed. If maximum rate or maximum angle of climb is not required, allow the aircraft to accelerate to normal climb airspeed.

Electric trim may not be adequate to relieve the high longitudinal control forces associated with the transition from landing attitude to climb attitude.

6. Flaps – Up (PF)

WINDSHEAR ESCAPE MANEUVER

1. Power – Maximum (PF)

2. Autopilot – Disengage (PF)

3. Pich Attitude/wings – Rotate towards 15 degrees/Gently Roll Wings Level (PF)

4. Configuration – Do not change (PF)

When clear of the windshear emergency event:

5. Waveoff Procedure (normal) – Execute (PF)

Note:

Move power lever aggressively to the forward stops. PNF should maintain power lever position. The additional performance gained by exceeding engine limits may give the margin needed for survival.

Do not stop or delay for analysis. Rotate smoothly at 3degrees/sec until reaching 15 degrees nose up. Stop rotation if stall warning sounds or stall buffet occurs.

If ground contact is imminent, rotate past the 15 degree target attitude and increase pitch to the lower limit of the stall warning threshold. Use intermittent stall warning as the upper limit for the pitch attitude until terrain clearance is ensured. The stall warning provides 4 to 12 knots of stall protection.

Do not change gear, flap, or trim configuration until terrain clearance is ensured.

PNF call out continuous radio altitude and altitude trend (i.e, “climbing…200 feet…descending…150 feet).

Advise ATC of any windshear encounter.

FLAP SYSTEM FAILURE

1. Flaps – Return to previously selected position (PF)

2. Flap Motor circuit breaker – Pull (LS)
