S-61R Pelican/Emergency Procedures
SECTION 7. EMERGENCY PROCEDURES
Contents
1 Engine Failure
1.1 Emergency Engine Shutdown
- Speed Selector – SHUT-OFF
- Fuel Valve - CLOSED
- Boost Pumps and Crossfeed – CLOSED
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.
- Ignition Switch - NORMAL
- Fire emergency shutoff selector handle - IN
- Speed selector (inop. engine) – SHUT-OFF
- Emergency fuel control lever - CLOSED.
- Fuel shut-off valve switch - OPEN.
- Crossfeed valve switch - AS REQUIRED.
- Boost pump switches - ON.
- Starter button – PRESS (until > 19% N1).
- Speed selector - GRD IDLE.
- Engine instruments – CHECKED
- Speed Selectors – MATCH TORQUES
While the engine is accelerating, check N1, TIT, Fuel Levels, N2, oil temp/press.
2 Single Engine Operation
2.1 To Continue Flight
- Speed Selector – 110%
- Collective Pitch – Climb at 150-200 fpm to safe autorotation height. Monitor RPM
- Engine Restart – ACCOMPLISH (if possible)
- Engine Shutdown – ACCOMPLISH (if restart is not possible)
- Land – AS SOON AS PRACTICAL
2.2 Single Engine Landing
- Speed Selector – 110%
- Approach Speed – 70 Knots
- At 150 feet AGL, reduce speed and rate of descent.
- Collective – Increase slightly to cushion the landing.
- Ground Contact – Slightly nose high, gently reduce collective and apply forward cyclic.
2.3 Single Engine Water Takeoff
- Off-load fuel, equipment and passengers as required.
- Fuel Dump Values – CLOSED
- Speed Selector – 110%
- Emerg. Fuel Lever - CLOSED
- Cyclic – Forward to maximum water taxi speed
- Collective – Raise for takeoff. Monitor RPM
- Climb - Establish
3 Fire (Engine/APU)
3.1 Engine Fire
- Speed Selector (affected eng.) – SHUT-OFF
- Fire Shutoff Handle – PULL
- Fire Extinguisher – MAIN (RESERVE if necessary)
- Boost Pumps (affected eng.) – OFF
- Crew – ALERTED
3.2 APU Fire
- APU Fuel Shutoff – SHUTOFF
- APU Fire Ext. – FIRE EXT.
- APU Master – OFF
4 Landing Gear Failure
4.1 Failure to Retract
- Landing Gear Lever – DOWN
- Gear down and locked – CONFIRM
- Land – AS SOON AS PRACTICAL
4.2 Failure to Extend
- Landing Gear Lever – DOWN
- Alt. Gear Lever – PULL
- Gear down and locked – CONFIRM
- Land – AS SOON AS PRACTICAL
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.
5 Emergency Start
5.1 Battery Start Procedures
- Rotor Brake – OFF
- Battery – OFF
- Accomplish all items in BEFORE STARTING ENGINE section as possible without turning on battery power.
- Start Mode – MANUAL
- Battery – ON
- No. 1 Engine – START
- Speed Selector – SHUT-OFF
- Start Switch – PRESS
- Wait – Min. 10 sec. and N1 above 19%
- Speed Selector – IDLE then slowly increase to 45% N1
- Starter – ABORT (disengage starter)
- All Gages – CHECKED
- Speed Selector – Increase slowly with minimum torque to 103%.
- Start Mode – NORMAL
- No. 2 Engine – Start using normal procedures
5.2 Start with Emergency Fuel Levers
This procedure should be avoided except when absolutely necessary to complete mission.
- Start Procedures – As normal up through advancing speed control to IDLE
- Emerg. Fuel Lever – Advance slowly to accelerate N1 to 56%.
- Emerg. Fuel Lever – Close slowly
- If engine continues to run at 56%, follow normal procedures.
- If N1 starts to drop off as the lever is closed, slowly reopen to restore 56% idle speed
6 Flight with Emergency Fuel Levers
- The Emergency Fuel Levers (EFL) bypass normal fuel meter to control fuel flow directly.
- If using EFLs due to fuel controller failure, control will only be possible above the valve position at the time of the controller failure.
- Collective changes must be made very slowly with reference to N2 for the affected engine to avoid rotor stall, or engine overspeed.
- Increases in collective will require increases on the EFL. Decreases in collective will require decreases in the EFL.
