EPs Flashcards
Hydraulic pump 1 fail & hydraulic pump 2 fail
Land as soon as possible
Flight control/rotor system vibrations or malfunctions on ground
Engine power control levers - OFF
Engine fuel system selectors - OFF
Fuel boost pump switches - OFF
Single engine failure:
Eng1 or Eng2 out
- Achieve safe single engine airspeed
- External cargo/stores - jettison
Tail rotor servo 1 fail with no backup pump on advisory or tail rotor servo 2 on advisory does not appear
Tail rotor servo switch - back up
Hydraulic pump 1 fail without back up pump on advisory
Back up hydraulic pump switch - ON
Flight control/rotor system vibrations or malfunctions in flight
Land as soon as possible
AFTER LANDING:
- ENG POWER CONT levers — OFF
- ENG FUEL SYS selectors — OFF
- FUEL BOOST PUMP switches — OFF
Engine control malfunction DEC/EDECU low side failure
Engine power control lever (low torque, low TGT) - Lockout
Dual engine failure
ENG1 & ENG2 OUT
Autorotate
Main transmission failure
LAND AS SOON AS POSSIBLE: (KEEP POWER APPLIED TO THE MAIN TRANSMISSION DURING DESCENT AND LANDING)
STABILATOR UNCOMMANDED NOSE DOWN PITCH ATTITUDE CHANGE
Cyclic mounted stabilator slew-up switch — Adjust
Lightning strike
Engine power control levers - ADJUST
Land as soon as possible
Loss of tail rotor control
If at low airspeed or hover a right yaw becomes uncontrollable:
- Collective — Reduce
- ENG POWER CONT levers — OFF (5 to 10 feet above touchdown)
Loss of tail rotor control
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)
Loss of tail rotor control
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 to 10 feet above touchdown)
- Collective — Adjust for landing
Fuel 1 pressure and fuel 2 pressure low
Land as soon as possible
Fires: APU/electrical/or engine
- 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
COUPLED FLIGHT DIRECTOR MALFUNCTION
- RMT SBY switch — Press to disengage FD modes
If coupled FD does not disengage: - CPLD switch — Press the uncouple FD
If coupled FD does not disengage: - FPS and TRIM switches — OFF
After FD is uncoupled: - FPS and TRIM switches — ON
Land as soon as possible
A landing at the nearest suitable landing area (e.g. open field). The primary consideration is to ensure the survival of occupants.
Land as soon as practicable
A landing at a suitable landing area. The primary consideration is the urgency of the emergency.
The term AUTOROTATE is defined as
adjusting the flight controls as necessary to establish an autoro-tational descent and landing.
The term EMER ENG SHUTDOWN is defined as
engine shutdown without delay. Engine shutdown in flight is usually not an immediate-action item unless a fire exists.
The term LOCKOUT is defined as
manual con-trol of engine RPM while bypassing DEC/EDECU func-tions. Bypass of the engine control will be required when NP1 or 2 decreases below normal demand speed due to a malfunction of the DEC/EDECU.
Lockout EP
ENG POWER CONT lever — Pull down and advance full forward while maintaining downward pressure, then adjust to set NR as required.
