1 Emergency Procedures

1.1 Engine Failure

1.1.1 Emergency Engine Shutdown

1. Speed Selector – SHUT-OFF
2. Fuel Valve - CLOSED
3. Boost Pumps and Crossfeed – CLOSED

1.1.2 Engine Restart in Flight

A failed engine should not be restarted unless it can be determined that it is safe to do so.

1. Ignition Switch - NORMAL
2. Fire emergency shutoff selector handle - IN
3. Speed selector (inop. engine) – SHUT-OFF
4. Emergency fuel control lever - CLOSED.
5. Fuel shut-off valve switch - OPEN.
6. Crossfeed valve switch - AS REQUIRED.
7. Boost pump switches - ON.
8. Starter button – PRESS (until > 19% N1).
9. Speed selector - GRD IDLE.
10. Engine instruments – CHECKED
While the engine is accelerating, check N1, TIT, Fuel Levels, N2, oil temp/press.
11. Speed Selectors – MATCH TORQUES

1.2 Single Engine Operation

1.2.1 To Continue Flight

1. Speed Selector – 110%
2. Collective Pitch – Climb at 150-200 fpm to safe autorotation height. Monitor RPM
3. Engine Restart – ACCOMPLISH (if possible)
4. Engine Shutdown – ACCOMPLISH (if restart is not possible)
5. Land – AS SOON AS PRACTICAL

1.2.2 Single Engine Landing

1. Speed Selector – 110%
2. Approach Speed – 70 Knots
3. At 150 feet AGL, reduce speed and rate of descent.
4. Collective – Increase slightly to cushion the landing.
5. Ground Contact – Slightly nose high, gently reduce collective and apply forward cyclic.

1.2.3 Single Engine Water Takeoff

1. Off-load fuel, equipment and passengers as required.
2. Fuel Dump Values – CLOSED
3. Speed Selector – 110%
4. Emerg. Fuel Lever - CLOSED
5. Cyclic – Forward to maximum water taxi speed
6. Collective – Raise for takeoff. Monitor RPM
7. Climb - Establish

1.3 Fire (Engine/APU)

1.3.1 Engine Fire

1. Speed Selector (affected eng.) – SHUT-OFF
2. Fire Shutoff Handle – PULL
3. Fire Extinguisher – MAIN (RESERVE if necessary)
4. Boost Pumps (affected eng.) – OFF
5. Crew – ALERTED

1.3.2 APU Fire

1. APU Fuel Shutoff – SHUTOFF
2. APU Fire Ext. – FIRE EXT.
3. APU Master – OFF

1.4 Landing Gear Failure

1.4.1 Failure to Retract

1. Landing Gear Lever – DOWN
2. Gear down and locked – CONFIRM
3. Land – AS SOON AS PRACTICAL

1.4.2 Failure to Extend

1. Landing Gear Lever – DOWN
2. Alt. Gear Lever – PULL
3. Gear down and locked – CONFIRM
4. Land – AS SOON AS PRACTICAL

1.4.3 Failure to Lock

If gear fail to indicate down and locked, land with minimum vertical and horizontal airspeed.

Note: Do not attempt to actuate gear until repairs have been made.

1.5 Emergency Start

1.5.1 Battery Start Procedures

1. Rotor Brake – OFF
2. Battery – OFF
3. Accomplish all items in BEFORE STARTING ENGINE section as possible without turning on battery power.
4. Start Mode – MANUAL
5. Battery – ON
6. No. 1 Engine – START
   1. Speed Selector – SHUT-OFF
   2. Start Switch – PRESS
   3. Wait – Min. 10 sec. and N1 above 19%
   4. Speed Selector – IDLE then slowly increase to 45% N1
   5. Starter – ABORT (disengage starter)
7. All Gages – CHECKED
8. Speed Selector – Increase slowly with minimum torque to 103%.
9. Start Mode – NORMAL
10. No. 2 Engine – Start using normal procedures

1.5.2 Start with Emergency Fuel Levers

This procedure should be avoided except when absolutely necessary to complete mission.

1. Start Procedures – As normal up through advancing speed control to IDLE
2. Emerg. Fuel Lever – Advance slowly to accelerate N1 to 56%.
3. Emerg. Fuel Lever – Close slowly
4. If engine continues to run at 56%, follow normal procedures.

1.6 Flight with Emergency Fuel Levers

1. The Emergency Fuel Levers (EFL) bypass normal fuel meter to control fuel flow directly.
2. If using EFLs due to fuel controller failure, control will only be possible above the valve position at the time of the controller failure.
3. Collective changes must be made very slowly with reference to N2 for the affected engine to avoid rotor stall, or engine overspeed.
4. Increases in collective will require increases on the EFL. Decreases in collective will require decreases in the EFL.

2 Servicing

2.1 General

This section describes the servicing model for your S61R. Servicing included normal servicing such as topping off of fluids, and refueling the aircraft, and
