Indications

Question 1

Answer 1

Dual Eng Failure

Question 2

Answer 2

SINGLE ENGINE FAILURE

CAUTION: Erroneous engine out indications may occur with malfunctions such as an alternator failure or engine underspeed (NP Failed Low <93) conditions

Question 3

Answer 3

ENGINE 1 OR ENGINE 2 OVERSPEED

CAUTION: NP overspeed protection may cause engine flameout gen-erating the ENGINE * AUTO IGN Advisory. If auto-ignition is success-ful, the NP overspeed flameout and auto-ignition cycle may repeat until the overpseed condition is corrected. The engine will not re-ignite following a NG overspeed protection event. See SINGLE EN-GINE FAILURE

If conditions persist - Achieve safe single engine flight conditions or land - Identify high NG engine as affected — Reference NG to manage engine power - POWER LEVER (affected engine) — Retard to equalize TQ or Ng

Question 4

Answer 4

NP FAILED LOW - LOW ROTOR RPM

Subsequent Actions
If conditions persists
- Achieve safe single engine flight conditions or land
- POWER LEVER (affected engine) — LOCKOUT and then retard to equalize torque output on both engines

Question 5

Answer 5

Engine compressor Stall

Subsequent Actions If condition persists
- Achieve safe single engine flight conditions
- POWER LEVER (affected engine) — Retard If TGT decreases and there is no further evidence of a stall
- POWER LEVER (affected engine) — FLY If stall condition recurs
- Achieve safe single engine flight conditions
- POWER LEVER (affected engine) — IDLE
- Continue per SINGLE ENGINE FAILURE

Question 6

Answer 6

APU Fire

If the APU FIRE button remains illuminated after pressing the PRI and RES FIRE DISCH buttons indicating that the fire is NOT extinguished, the crew should LAND WITHOUT DELAY.

Subsequent Actions
- ECS — OFF (ACFT UTIL page) to reduce smoke in crew station After landing
- EMERGENCY SHUTDOWN

Question 7

Answer 7

HYDRAULIC FAILURE - PRIMARY & UTILITY HYDRAULIC PSI LOW

WARNING 1: Immediate emergency action must follow failure of both hydraulic systems, any hesitation could result in loss of helicop-ter control.

WARNING 2: Movement of the flight controls prior to activation of the EMERG HYD button may cause the crewmember to decouple the ARDD which will result in a loss of control in the respective axes.

WARNING 3: Once the EMERG HYD button is pressed on, it must remain on. Flight control inputs and elevated G loading must be kept to a minimum. Aircrew will not be able to move the flight controls when the Accumulator (ACC) Hydraulic Pressure drops below ap-proximately 1650 PSI.

Subsequent Actions - Monitor Accumulator (ACC) hydraulic pressure

Question 8

Answer 8

LOSS OF TAIL ROTOR THRUST - CONTINUED FLIGHT NOT POS-SIBLE / LOW AIRSPEED OR HOVER

WARNING: If engine POWER LEVERS are not selected off prior to cushioning touchdown, Yaw to the right will increase significantly as the collective is increased.

CAUTION: The CHOP button is not on the BATT Bus. If the CHOP button is used to minimize main rotor torque, the crew must immedi-ately retard the POWER LEVERS to IDLE or OFF to prevent rapid engine acceleration and increased Yaw after the generators drop of-fline (74-77% NR)

Question 9

Answer 9

TAIL ROTOR FIXED PITCH - LOW AIRSPEED OR HOVER

WARNING: Special attention should be given to collective applica-tion after touchdown. Fully lowering the collective could result in air-craft roll in a high power fixed pitch condition

Question 10

Answer 10

MAIN TRANSMISSION TAIL ROTOR BEVEL IDLER GEAR SET FAILURE

WARNING 1: Decoupling the AARD will result in loss of control in the respective axis, even after the emergency hydraulics are acti-vated.

WARNING 2: Hydraulic power may be limited to as little as 30 - 41 seconds.

WARNING 3: If engine power levers are not selected off prior to cushioning touchdown, yaw to the right will increase significantly as the collective is increased.

Question 11

Answer 11

MAIN XMSN INPUT DRIVE CLUTCH FAILURE - IN FLIGHT

• Achieve safe single engine flight conditions or land

Subsequent Actions
- POWER LEVER (affected engine) — IDLE If NP drops below NR
- POWER LEVER (affected engine) — OFF See SINGLE ENGINE FAILURE (CARD W-6)
- LAND AS SOON AS PRACTICABLE If NP does not drop below NR
- LAND AS SOON AS POSSIBLE - POWER LEVERS — OFF both engines simultaneously

Question 12

Answer 12

DUAL MP FAILURE - MP1 AND MP2 FAIL
- At night (NVS Flight) - Exit the NOE environment

WARNING 1: Loss of aircraft notifications (Voice, Warnings, MSTR WARN, MSTR CAUT, Advisories), except fire warning lights, will occur during a dual MP failure. The fire detection/extinguishing panel remains fully operational.

WARNING 2: In the event of a dual MP failure, aircraft ARM/SAFE state remains in the last commanded selection. Do not fire the weap-ons as weapon system inhibits are not available. Crews must ensure the weapons are de-actioned to safe the aircraft.

Question 13

Answer 13

FLIGHT CONTROL MALFUNCTION

• FMC release button — Press

WARNING 1: If experiencing a flight control restriction, both crew stations must verify collective friction position (if applicable) and that the flight controls are clear of foreign objects.
WARNING 2: Force TRIM will not be turned off except in a failed or partial failed state. Positive control of the cyclic and pedals must be maintained when the MAG FORCE TRIM OFF Caution is dis-played on the EUFD

Uncommanded Inputs -
FMC – Re-engage unaffected FMC axes (A/C UTIL page)
If Uncommanded Inputs clear - LAND AS SOON AS PRACTICABLE
If Uncommanded Inputs remain - LAND AS SOON AS POSSIBLE

Question 14

Answer 14

BUCS Fail

• Transfer flight controls to rear crew station

Subsequent Actions - Attempt to re-engage FMC axes on ACFT UTIL page (if disen-gaged). If axes re-engages and BUCS FAIL Caution is removed, continue mission

WARNING 1: A severance between crew stations will generate a BUCS FAIL * Caution.

WARNING 2: BUCS FAIL and FMC DISENGAGED Cautions will be displayed following a PRI HYD PSI LOW Caution.

Question 15

Answer 15

DUAL ENGINE FUEL PSI LOW

FUEL Page, BOOST button — Press ON

Land as soon as Possible

WARNING: With ENG 1 FUEL PSI LOW and ENG 2 FUEL PSI LOW Cautions the crew should be prepared to establish a flight pro-file that facilitates autorotation

Question 16

Answer 16

SINGLE GENERATOR AND SINGLE RTRU FAIL

Affected GEN 1 or GEN 2 — OFF/RESET, then ON (see CAU-TION)

LAND AS SOON AS PRACTICABLE

CAUTION: Failure or reset of GEN 2 may result in BUCS FAIL and a FMC DISENGAGED Cautions and a loss of one or more FMC channels. After completing a GEN 2 RESET, reset the BUCS FAIL and the FMC DISENGAGED Cautions by re-engaging the affected FMC channels. If the BUCS FAIL is not associated with the GEN 2 Failure or reset, the pilot should assume other problems have oc-curred and refer to BUCS FAIL

Answer 17

GENERATOR 1 AND GENERATOR 2 FAIL - COMPLETE LOSS OF ELECTRICAL POWER

LAND AS SOON AS POSSIBLE

• GEN 1 and GEN 2 — OFF/RESET, then ON (see CAUTION) If either generator recovered - Continue with SINGLE GENERATOR AND SINGLE RTRU FAIL
