FP-5 T-44 Emergency Procedures 5/14/15
Ground Emergencies • Abnormal Start • Emergency Engine Shutdown on Deck • Loss of Brakes • Hot Brakes • Brake Fire • Jammed Controls on Deck
Abnormal Start • Execute Memory Items: • Condition lever – FUEL CUTOFF (note ITT decrease to below 790). • Starter – OFF. • Know your starter limitations • If another start is attempted, allow 60 seconds delay to drain fuel and cool starter, then motor for 15 seconds minimum.
Emergency Engine Shutdown on Deck • Confirm, if possible, the fire actually exists by checking instruments and nacelles. • Execute Memory Items: • Condition levers – FUEL CUTOFF. • Firewall valves – CLOSED. • Boost pumps – OFF. • Fire extinguisher – As Required. • AUX BATT Switch – OFF. • Gang Bar – OFF. • Evacuate aircraft.
Loss of Brakes/ Hot Brakes • Have other pilot check his/her pedals • Maintain directional control • Utilize prop reverse or beta to stop • Do not taxi; maneuver into open area • Check shuttle valve by pulling the top of the brake pedal. • Call for assistance for tow • Usually the result of excessive braking • Use reverse and minimum braking to stop • Allow the brakes to cool using prop wash • Locking the wheels may occur resulting in blown tires • Call for assistance for tow
Brake Fire • Execute Memory Items: • Stop aircraft. • Firefighting assistance – Request. • Emergency Shutdown on Deck Checklist – Execute. • Preferable to stay behind the aircraft. If the wheels explode because of rapid cooling, fragments will fly sideways from the wheel. • Do not attempt to fight the fire!
Jammed Controls on Deck • Check yaw damp/auto pilot OFF • Maintain controls in the jammed condition • Call for immediate inspection
Takeoff Emergencies • Aborting Takeoff • Engine Failure During Takeoff • Engine Failure After Takeoff • Tire Failure • Abnormal Takeoffs
Aborting Takeoff • The decision to abort or continue is dependent on the length of remaining runway, airspeed, gross weight, and density altitude. • Use extreme caution if takeoff surface is not hard and dry (reverse considerations). • Mechanical stops are incorporated in the throttle quadrant; downward pressure must be applied to allow for reversing power.
Aborting Takeoff • Execute Memory Items: • Announce “Abort.” • Power levers – IDLE • Reverse – As Required • Brakes – As Required • (Prior to departing the prepared surface): • Condition levers – FUEL CUTOFF • (As soon as practicable): • Firewall Valves – CLOSED • Boost pumps – OFF • Fire extinguisher(s) – As Required • AUX BATT switch – OFF • Gang Bar – OFF • Evacuate aircraft.
Engine Failure After Takeoff • Execute Memory Items: • Power – As Required • Gear – UP • Airspeed – As Required (Vxse or Vyse) • Emergency Shutdown Checklist – Execute. • Warning: Do NOT retard the power lever until the feathering sequence is completed. • Warning: No climb can be obtained with an inoperative engine windmilling. Always ensure the failed engine prop feathers!
Tire Failure • If occurs during takeoff, ABORT. • Control the aircraft using rudder, nosewheel steering and brakes, as necessary.
Abnormal Takeoffs • You won’t do these. • Reference NATOPS for: • Obstruction Clearance Takeoff • Soft-Field Takeoff • Short-Field Takeoff
In-Flight Emergencies (Part I) • Engine Failure • Emergency Shutdown Checklist • Jammed Power Lever • Airstarts • Single-Engine Crossfeed
Engine Failure • Relax! No unusual handling characteristics. • Sufficient rudder trim to maintain level flight above 100 • knots (below requires manual augment) • Warning: Waving-off with full flaps will result in a loss of 200’ before climb is established. • Execute Memory Items if experienced after takeoff. • DO NOT relight with a MOVEOFF item: • Mechanical Malfunction • Overheat • Vibration • Explosion • 0% N1 RPM • Fire • Fuel Fumes
Emergency Shutdown Checklist • Execute Memory Items: • Power lever – IDLE • Prop lever – FEATHER • Condition lever – FUEL CUTOFF. • FTI: “Is it a FIRE or a FUEL LEAK?” • Firewall Valve – CLOSED • Fire extinguisher – As Required • Bleed air – CLOSED
Engine Shutdown Checklist • Continue with steps 7-8, conditions permitting. • Don’t interrupt the checklist to conduct the Landing Checklist • Fly the airplane first. Always remember: AVIATE, NAVIGATE, COMMUNICATE
Jammed Power Lever • If no abnormal conditions are detected, consideration can be given to keeping the engine running. Prior to landing… • Execute Memory Items: • Condition lever (affected engine) – FUEL CUTOFF • Emergency Shutdown Checklist – Execute (PF)
Airstarts • Either generator-assisted or battery-only (windmilling). • You will see each one in the C4300 block. • Always determine the cause of failure first!
Airstarts • Generator-assisted: Reference NATOPS. • This is the normal procedure for relight.
Airstarts • Windmilling: for inadvertent shutdown. • Execute Memory Items: • Power lever (failed engine) – IDLE • Prop lever (failed engine) – Full Forward • Condition lever (failed engine) – FUEL CUTOFF • Firewall valve – OPEN • Autoignition – ARMED • Condition lever – LOW IDLE • Power – As Required • Complete steps 8-10.
Single-Engine Crossfeed • Reference NATOPS • OPEN the crossfeed valve • Turn OFF the boost pump for the non-feeding tank • Wing SOP: Fuel balancing is not authorized • Only use for emergency purposes.
In-Flight Emergencies (Part II) • In-Flight Fire • Smoke/Fire of Unknown Origin • Smoke & Fume Elimination • Oil System Failure • Fuel System Failure • Fuel Leaks • Fuel Siphoning • Electrical System Failure • Propeller Failure • Pilot Emergency Static Air Source
In-Flight Fire • CONFIRM the fire exists. • Sunlight may cause illumination of the warning light. • If secondaries exist, shutdown. • If no secondaries exist, consideration should be given to shutdown.
In-Flight Fire Fire, confirmed.
Smoke/Fire of Unknown Origin • This checklist may be exited once the source is found. • Pausing between last 5 steps may isolate electrical fire. • With the Gang Bar OFF, you will still have AUX battery items available (CRANE) • Maintain VMC if possible! • Land/ditch immediately if fire uncontrollable. • Execute Memory Items: • Crew – Alerted. • Cabin temp mode – OFF • Vent blower – AUTO • Oxygen masks/MIC switches – As Required
Smoke & Fume Elimination • Execute Memory Items: • Oxygen masks/MIC switches – As Required • Pressurization – DUMP • Closing bleed air valves will reduce fumes • Magnetic compass fluid is highly toxic! Execute memory items.
Oil System Failure • Pressure below 85psi is undesirable • Tolerate for completion of flight • Reduce power, land as soon as practicable • Pressure below 40psi, temp above 99 is unsafe, execute a shutdown. • CHIP light – check for secondaries! • Either case, land as soon as possible • If none are detected, engine may be used with discretion for situations requiring power.
Fuel System Failure • Engine driven fuel pump failure leads to flameout • Boost pump failure requires crossfeed or suction lifting • Reference NATOPS! Your range may be affected.
Fuel Leaks • Execute Memory Items: • Condition lever – FUEL CUTOFF • Emergency Shutdown Checklist – Execute • An apparent fuel leak might be fuel siphoning if it originates from the fuel cap.
Fuel Leaks • FUEL SIPHONING: Extreme nose low attitudes will aggravate the fuel siphoning condition (airspeed 140 knots max). • FUEL LEAK: Secure engine with memory items.
Electrical System Failure • Execute Memory Items: • Generator – OFF, reset momentarily, then ON. • (If generator will not reset): • Generator – OFF • Current Limiter (Battery Anmeter) – Checked • Maintain VMC whenever possible. • Know your wet compass characteristics and “Big 5” for total electrical failure (in FTI). You will see this in syllabus.
Propeller Failure • Three levels of “governing”: Primary, overspeed, and the fuel-topping governors. • Practice the FTI CRM brief. • Don’t shut down engine/prop that feathers properly unless secondary indications are noted. • Note: Landing with an overspeeding prop is strongly discouraged. The ultimate goal is to feather the prop.
Propeller Failure • Execute Memory Items: • Attempt to adjust prop RPM; if normal limits exist, continue operation. If not, complete the following: • Power lever – IDLE • Prop lever – FEATHER • Alternate Prop Feathering Checklist – As Required. • Prop Linkage Failure results in 2200 RPM or the last RPM setting. Manipulate the other prop to match them, and land (reversing, as required).
Pilot Emergency Static Air Source • Reference NATOPS Chapter 25 for gauge error • Airspeed and Altitude will be approximately +5 KIAS/+50 feet in error on pilot’s side at approach speeds/altitudes (you will actually be lower and slower).
In-Flight Emergencies (Part III) • Electrothermal Propeller Deice • Surface Deice • Loss of Pressurization • Explosive Decompression • Emergency Descent Procedure • Cabin Door Open Light Illuminated • Flight Guidance Failure • In-flight Damage / Spin/OCF Recovery • Terrain Warning
Electrothermal Propeller Deice • Normal range is 14-18 amps. • 0 or 23 amps is unusable • Imbalance requires manipulating the prop levers to aid in ice removal.
Surface Deice • Stall speeds will significantly increase with the wing deice boots inflated. • If boots fail to deflate, pull the SUR DE-ICE circuit breaker.
Loss of Pressurization • Reference NATOPS. • Approximately 75% N1 is required to maintain pressurization during descent. • Utilizing the TEST position may restore pressurization; pull the PRESS CONTROL CB to remove electrical power and maintain pressure (CAUTION – reset prior to landing!).
Explosive Decompression • Execute Memory Items: • Oxygen masks/MIC switches – As Required • Descend – As Required • Do not confuse fog with smoke. • Descend below 10,000’ to remove mask or below 18,000’ with masks on (3710 cabin altitude limits).
Emergency Descent Procedure • Execute Memory Items: • Power levers – IDLE • Props – FULL FORWARD • Flaps – As Required • Landing gear – As Required • Airspeed – As Required • Windshield heat – As Required • Don’t exceed airframe limitations • For training, stick with just props full forward.
Cabin Door Open Light Illuminated • Don’t attempt to check the door • Ensure that all occupants are seated and belted • Depressurize the cabin • Land
Autopilot Disengagement • Automatic: • Any interruption/failure of power • Failure condition of FGC • Flight control failure • A/P trim failure • Stall condition • Extreme attitude • In any of these cases, the horn will continue until the disc. button on the yoke is pressed. • Manual: • Pushing the AP/YD button (FGP) • Go-Around button (LH throttle) • AP/YD disc. button (yoke) • Manual trim switch (yoke) • DISC bar is positioned down • Avionics Master OFF
