Q

ENGINE RESTART

A

CAUTION LIGHT
(If cause of failure is obviously mechanical, as evidenced by abnormal metallic or grinding sounds, do not attempt restart).

If flameout occurs, the control system automatically responds by re-enabling the igniters until the engine has relit. If the Ng speed continues to fall below 50% and the automatic relight did not restart the engine, a pilot initiated restart may be attempted in flight if time and altitude permit.

Q

DRIVESHAFT FAILURE

A

WARNING!

FAILURE OF MAIN DRIVESHAFT TO TRANSMISSION WILL RESULT IN COMPLETE LOSS OF POWER TO MAIN ROTOR. ALTHOUGH COCKPIT INDICATIONS FOR A DRIVESHAFT FAILURE ARE SIMILAR TO AN ENGINE OVERSPEED, IT IS IMPERATIVE THAT AUTOROTATIVE FLGHT PROCEDURES BE ESTABLISHED IMMEDIATELY. FAILURE TO REACT IMMEDIATELY TO LOW RPM AUDIO, RPM LIGHT AND NP/NR TACHOMETER CAN RESULT IN LOSS OF CONTROL.

INDICATIONS:
1. Left yaw
2. Rapid decrease in Nr
3. Rapid increase in Np
4. Low RPM audio
5. Illumination of RPM light
6. MFD switches to ENGINE page
7. Possible increase in noise level due to over speeding engine and driveshaft breakage.

(Engine OVERSPEED trip system will activate at 118% Np causing fuel flow to go to minimum. After initial overspeed, FADEC will Adjust flow to maintain engine at 100% Np.)

PROCEDURE:
1. Maintain heading and altitude control
2. Collective - Adjust as required to maintain 85 to 107% Nr.

(Minimum rate of descent airspeed is 55 KIAS. Maximum glide distance airspeed is 80 KIAS.)

1. FADEC fail audio activated
2. FADEC FAIL warning message illuminated
3. FADEC MANUAL caution message illuminated
4. RESTART FAULT advisory message illuminated
5. FADEC MODE switch MAN light illuminated

PROCEDURE: WARNING!
(Dependent of flight profile (takeoff, climb, or descent) and power setting at time of failure, the transition to manual mode may result in an Nr/Np overspeed or underspeed within 2 to 7 seconds after the FADEC FAIL WARNING, requiring positive movements of collective and throttle to control Nr.)
1. Throttle - if time permits, match throttle bezel position to NG indication.
2. Nr/Np - Maintain 95 to 100% with collective and throttle.
3. FADEC MODE switch - depress one time, muting FADEC fail audio. Auto relight message illuminates.

(Depressing FADEC MODE switch one time, will only mute FADEC fail audio and activate ignition. This step should not be accomplished until pilot is firmly established in MAN control.)

Q

Battery info and notes

A

WARNING!
PRIOR TO BATTERY DEPLETION, ALTITUDE MUST BE REDUCED BELOW 8000’ Hp (JET A) or 4000’ Hp (Jet B). UNUSABLE FUEL MAY BE AS HIGH AS 151.0 POUNDS AFTER THE BATTERY IS DEPLETED DUE TO INABILITY TO TRANSFER FUEL FROM FORWARD CELLS.

Note:
With battery and generator Off, only standby airspeed and altimeter will be available.

Note:
With battery and generator Off, an 80% charged battery will operate left fuel boost pump and left fuel transfer pump for approximately 1.7 hours (2.8 hours with optional 28 amp-hour battery).

Note:
Pedal stop disengages with loss of electrical power.

When throttle is repositioned to the idle stop (during engine shutdown), the PMA will go offline and the engine may flame out.

22
Q

Tail Rotor (General)

A

There is no single emergency procedure for all types of anti-torque malfunctions. One key to a pilot successfully handling a tail rotor emergency lies in the ability to quickly recognize the type of malfunction that has occurred.

23
Q

Complete loss of tail rotor thrust

A

This is a situation involving a break in drive system (e.g. severed driveshaft), wherein tail rotor stops turning and delivers no thrust.

INDICATIONS:
1. Uncontrollable yawing to right (left side slip)
2. Nose down tucking.
3. Possible roll of fuselage

Note:
Severity of initial reaction of helicopter will be affected by airspeed, CG, power being used, and Hd.

PROCEDURE: Hovering
Close throttle and perform a hovering autorotation landing. A slight rotation can be expected on touchdown.
In flight
Reduce throttle to idle, immediately enter autorotation, and maintain a minimum airspeed of 55 KIAS during descent.

Note:
When a suitable landing site is not available, vertical fin may permit controlled flight at low power levels and sufficient airspeed. During final stages of approach, a mild flare should be executed, making sure all power to rotor is off. Maintain helicopter in a slight flare and smoothly use collective to execute a soft, slightly nose-high landing. Landing on aft portion of skids will tend to correct side drift. This technique will, in most cases, result in a run-On type landing.
Caution
In run-On type landing after touching down, do not use cyclic to reduce forward speed.

24
Q

Fixed pitch failures

A

This is a situation involving inability to change tail rotor thrust (blade angle) with anti-torque pedals.

INDICATIONS:
1. Lack of directional response
2. Locked pedals

Note:
If pedals cannot be moved with a moderate amount of force, do not attempt to apply a maximum effort, since a more serious malfunction could result. If helicopter is in a trimmed condition when malfunction occurred, Q and airspeed should be noted and helicopter flown to a suitable landing area. Certain combinations of Q, Nr, and airspeed will correct a yaw attitude, and these combinations should be used to land the helicopter.

PROCEDURE:

Note:
Pull pedal stop emergency release to ensure pedal stop is retracted.
Hovering
Do not close throttle unless a severe right yaw occurs. If pedals lock in any position at a hover, landing from a hover can be accomplished with greater safety under power-controlled flight rather than by closing throttle and entering autorotation.

                              I flight - left pedal applied In a high power condition, helicopter will yaw to left when power is reduced. Power and airspeed should be Adjusted to a value where a comfortable yaw angle can be maintained. If airspeed is increased, vertical fin will become more effective and an increased left yaw attitude will develop. To accomplish landing, established a power-on approach with sufficiently low airspeed (zero if necessary) to attain a rate of descent with a comfortable side slip angle. (A decrease in Np decreases tail rotor thrust.) As collective is increased just before touchdown, left yaw will be reduced.

                      In flight - right pedal applied In cruise flight or reduced power situation, helicopter will yaw to right when power is increased. A low power, run-On type landing will be necessary by gradually reducing throttle to maintain heading while adding collective to cushion landing. If right ya becomes excessive, close throttle completely.
25
Q

Loss of hydraulic pressure

A

INDICATIONS:
1. HYDRAULIC SYS caution message illuminated
2. Grinding or howling noise from pump
3. Increase in force required to move flight controls
4. Feedback forces may be evident during flight control movement

PROCEDURE:
1. Reduce airspeed to 70 to 100 KIAS
2. HYD System circuit breaker - Out. If hydraulic power is not restored, push breaker in.
3. For extended flight set comfortable airspeed, up to 120 KIAS, to minimize control forces.
5. Land as soon as practical
6. A run-On landing at effective translational lift speed (approximately 15 knots) is recommended.

26
Q

Flight control actuator malfunction

A

An actuator hardover can occur in any flight control axis, but a cyclic cam jam will only occur in the fore and aft axis. An actuator hardover is manifested by uncommanded movements of one or two flight controls. If two controls move, the pilot will find one of these controls will require a higher than normal control force to oppose the movement. This force cannot be trimmed to zero without turning the HYD SYS switch Off. Once the hydraulic boost is off, the forces on the affected flight control will be similar to the “normal” hydraulic Off forces.

INDICATIONS:
1. Uncommanded flight control movements
2. High flight control forces to oppose movement in one axis
3. Feedback forces only in affected flight control axis
4. Flight control forces normal in unaffected axis

PROCEDURE:
1. Attitude - maintain
2. HYD SYS switch - Off
3. Airspeed - set to 70 to 100 KIAS
4. Land as soon as possible

Q

Cyclic Cam Jam

A

A cyclic cam jam can only occur in the fore and aft axis, whereas, an actuator hardover can occur in any flight control axis. A cyclic cam jam is manifested when a commanded control movement requires a higher than normal fore and aft spring force. The force felt when moving the cyclic for and aft with a cam jam is the result of overriding a spring capsule.

INDICATIONS:
1. High (approximately 15 pounds fore and aft cyclic control forces.
2. Normal pedal, collective and lateral cyclic control forces.

PROCEDURE:
1. Helicopter pitch attitude - Maintain normal pitch attitudes with forward or aft cyclic force
CAUTION
