(RAASH)
Rotor speed
Attitude
Altitude
Speed
Heading

Question 3

Dual-Engine Failure

Answer 3

• Autorotate

Question 4

Single-Engine Failure

Answer 4

• Achieve safe single engine airspeed (if possible)

- External cargo/stores - Jettison (if required)

Question 5

Fires: APU/Electrical/Engine

If ENG EMER OFF Handle/APU fire T-handle illuminates in flight:

Answer 5

• Airspeed adjust to 80 KIAS or less
• ENG POWER CONT lever - OFF
• ENG EMER OFF handle/APU fire T-handle - Pull (as appropriate)
• FIRE EXTGH switch - MAIN/RESERVE as required

If an electrical fire is present:
- BATT and GENERATORS switches - OFF

Question 6

Engine Control Malfunction - (DEC/EDECU) Low Side Failure

Answer 6

If NR continues to decrease and single engine flight is not possible:
- ENG POWER CONT lever (low Q/TGT engine) - LOCKOUT (Maintain Q approximately 10% below other engine)

Question 7

Stabilator Uncommanded Nose Down Pitch Attitude Change

Answer 7

If an uncommanded nose down pitch attitude occurs:

- Cyclic mounted stabilator slew-up switch - Adjust (as required to arrest nose down pitch rate)

Question 8

Flight Control/Rotor System Vibrations or Malfunctions on Ground

Answer 8

• ENG POWER CONT levers - OFF
• ENG FUEL SYS selectors - OFF
• FUEL BOOST PUMP switches - OFF

Question 9

Lightning Strike

Answer 9

• ENG POWER CONT levers - Adjust (as required to control NP and NR)

Question 10

Loss of Tail Rotor Control

Answer 10

If during cruise flight a right yaw becomes uncontrollable:

• AUTOROTATE - Maintain airspeed at or above 80 KIAS
• ENG POWER CONT LEVERS - OFF (during deceleration when intended point of landing is assured)

If at low airspeed or hover a right yaw becomes uncontrollable:

• Collective - Reduce
• ENG POWER CONT levers - OFF (5-10 feet above touchdown)

If an uncontrolled left yaw develops during low airspeed or hover:

• ENG POWER CONT levers - Retard
• Collective - Increase (NR will decrease)
• ENG POWER CONT levers - OFF (5-10 feet above touchdown)
• Collective - Adjust for landing

Question 11

1 Hydraulic Pump No Back-Up Pump

Answer 11

BACK-UP HYD PUMP switch - ON

Question 12

Tail Rtr Servo #1 Caution and Back-Up Pump on does not appear

Answer 12

TAIL SERVO switch - BACK-UP

Subsequent actions:
Backup hydraulic pump switch: On

Question 13

Emergency Release of Rescue Hoist (External)

Answer 13

• If possible, relieve tension on the cable.

- On either pilot’s or crew panel CABLE CUT button - Press

Question 14

Hoist Runaway or Motor Brake Failure (External)

Answer 14

• Hoist Operator announce runaway
• Hoist Operator pendant thumbwheel UP/DOWN as required to control cable/load

If control is possible:
- Maintain positive pressure in corrective direction

If control is not possible:
- Pilots hoist control panel PILOT OVERRIDE switch - UP or DN, as required to control cable/load

If control is possible (Motor Brake Failure):

• Maintain positive pressure in corrective direction
• See Urgency to Land

If control is not possible (Hoist Runaway):

• HOIST POWER SWITCH - OFF
• See Urgency to Land
