2. PCL (malfunctioning engine)—Retard to set:
a. Torque 10% below good engine, or
b. Matched Ng, or
c. Matched TGT.
C = Np overspeed
N = High collective
N = Ng is a highly reliable signal
N = Torque signal may be erratic or drop off
Engine High Side Failure on Deck
- PCLs - IDLE
Engine Low Side Failure
1 x A
Identification
- Engine Malfunction in Flight emergency procedure - Perform.
A = controlling engine in LOCKOUT
ID =
1. TRQ is 10% below good engine
2. Ng is 5% or less than good engine
3. Np is at or below 98%
4. Nr is at or below 97%
Engine Torque or TGT Spiking/Fluctuations
1 x W
If an engine instrument is spiking/fluctuating and inducing secondary indications in Ng, Np, and/or Nr:
1. Engine Malfunction in Flight emergency procedure —Perform.
If fuel contamination is suspected:
2. Land as soon as possible.
W = PCL movement
Compressor Stall
1 x C
- Engine Malfunction in Flight emergency procedure - Perform.
- PCL (malfunctioning engine) - IDLE
C = Ng Decay Relight feature
Engine High Speed Shaft Failure
1 x C
1 x N
- Engine Malfunction in Flight emergency procedure - Perform.
- PCL (malfunctioning engine) - OFF.
C = engine will overspeed
N = Np sensor unreliable
Abort Start
1 x C
5 x Indications
To abort start:
1. PCL - OFF.
2. ENGINE IGNITION switch - OFF.
If engine oil pressure is indicated:
3. Starter - Engage.
C = failure to secure fuel flow (ENG overtemp)
Indications:
1. Ng does not reach 14% within 6 seconds after starter initiation.
2. No oil pressure within 30 seconds after starter initiation (do not motor engine).
3. No light-off within 30 seconds after moving PCL to IDLE.
4. ENG Starter advisory disappears before reaching 52% Ng.
5. TGT is likely to exceed 851°C before idle speed is attained.
Engine Malfunction During Hover/Takeoff
- Control Nr
- CONTGCY PWR switch - ON.
If a suitable landing exists or unable to transition to forward flight: - Set level attitude, eliminate drift, cushion landing.
If able to transition to forward flight: - Engine Malfunction in Flight emergency procedure - Perform.
Dual Engine Failure
- Autorotation - Establish.
- Immediate landing/ditching emergency procedure - Perform.
If time and altitude permit: - Emergency air restart emergency procedure - Perform.
Single Engine Failure in Flight
1 x Advisory about ENG OUT light
- Engine Malfunction in Flight emergency procedure - Perform.
Advisory = Warning light is activated by the vertical instrument when Ng decreases below 55%. In the event of an isolated Ng signal failure, the ENG OUT light will be illuminated with the engine operating normally.
Engine Air Restart

- PCL(s) - Advance to FLY after starter dropout.
W = APU unavailable
C = crossbreed starts
N = single or dual engine starts
APU emergency start
- ECS - OFF.
- AIR SOURCE ECS/START switch - APU.
