Q

ENGINE TORQUE OR TGT SPIKING/FLUCTUATIONS

TORQUE SPLIT

A

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.

WARNING

PCL movement during engine fluctuations may precipitate an engine failure. Consider performing APU Emergency Start procedure prior to manipulating the PCL. Maintaining a low power setting when moving the PCL will minimize the Nr decay rate if the malfunctioning engine fails.

If engine electronic circuitry is suspected:

  1. PCL (malfunctioning engine) - Momentarily advance to LOCKOUT, then retard to set:
    a. Torque 10% below good engine, or
    b. Matched Ng, or
    c. Matched TGT.

If fluctuations persist:
4. PCL (engine in LOCKOUT) - Retard to idle, then retur to FLY.

  1. Repeat Steps 3 and 4. for other engine, as required.

If an engine instrument is spiking/fluctuationg with no secondary indications:

  1. Land as soon as practicable.

Q

GROUND RESONANCE/UNUSUAL VIBRATIONS ON DECK

A 
If ground resonance is encountered and a
safe takeoff is possible:
*1. Takeoff immediately.
*2. Unusual Vibrations in emergency procedure - Perform
If ground resonance is not encountered, or a safe takeoff is not possible:
*3. Collective - Lower.
*4. PCLS - OFF.
*5. Rotor brake :
Apply as required.
Flight
WARNING
• Ground resonance can occur
rapidly (within three seconds),
and produce violent lateral,
vertical, and circular vibrations
resulting in difficulty reaching
PCs, pilot-induced oscillations and
possible dynamic rollover.
• Failure to ensure that ground
personnel are clear of the rotor arc
and aircraft is free from the deck or
chains may result in loss of aircraft
or ground personnel.
34
Q

TAIL/INTERMEDIATE TRANSMISSION MALFUNCTION

Warnings

A 
WARNING
High power settings require maximum
performance of the tail rotor
drive system and may precipitate
ultimate drive failure.
Consideration should be given to
transiting at an altitude sufficient
to enter an autorotation and
performing the applicable steps of
the Immediate Landing/Ditching
emergency procedure.
35
Q

Loss of tail rotor control

Warnings

A 
WARNING
• Following the appearance
of the #1 TAIL RTR
SERVO caution without
the associated BACK UP
PUMP ON and #2 TAIL RTR
SERVO ON advisories, the
aircraft will demonstrate
normal yaw responses in
flight regimes that do not
require excessive tail rotor
performance; however, at
slower airspeeds, below
approximately 40 KIAS,
more pronounced effects of
loss of tail rotor control may
become more apparent.

After touchdown, rapid
reduction of collective or
PCs may cause excessive
and uncontrollable yaw rates.

• If an uncontrolled right
yaw develops at too low
of an airspeed, loss of
waveoff capability may
result. Increasing collective
may increase the yaw
to unrecoverable rates
Performing Loss Of Tail Rotor
Drive (Altitude And Airspeed
Not Sufficient To Establish
Autorotation) procedure
may be required.
