Normal Procedures

Question 0

Systems check

Answer 0

Uncommanded control movement or motoring with hydraulic system off may indicate hydraulic system malfunction.

1. HYD SYS switch — OFF.
2. HYDRAULIC SYSTEM message — Illuminated.
3. HYD SYS switch — HYD SYS (on).
4. HYDRAULIC SYS message — Extinguished.

Question 1

Startup sequence

Answer 1

1. Collective — Full down.
2. Cyclic and pedals — Centered and CYC CTR message extinguished.
3. Throttle — Idle position.
4. START switch — Momentarily press (hold for approximately 1 second) and observe START and AUTO RELIGHT messages are illuminated.
5. PSI — Monitor start limitations.
6. START message — Extinguished at 50% NG (starter has disengaged).
7. AUTO RELIGHT message — Extinguished at 60% NG.
8. Engine and transmisison oil pressures.
9. Idle — 63 ±1% NG.
10. BATT switch — ON (if applicable).
11. GEN switch — GEN (on); observe GEN FAIL message extinguishes.
12. Voltmeter — 28.5 ±0.5 volts.

Question 2

Engine run up

Answer 2

1. Throttle — Increase smoothly to FLY detent position while maintaining torque below 40%. Check RPM warning light and audio extinguished at 95% NR.
2. NR and NP needles — Check matching and indicating 100%.
3. ELT (if installed) — Check for inadvertent transmission.
4. Flight controls — Check freedom with minimum friction.
5. ENG ANTI ICE switch — ENG ANTI ICE (on); check for MGT increase and illumination of ENGINE ANTI-ICE message.

NOTE

If temperature is below 5°C (40°F) and visible moisture is present, ENG ANTI ICE shall be on.

6. ENG ANTI ICE switch — OFF; check MGT returns to normal and ENGINE ANTI-ICE message extinguishes; then ENGINE ANTI ICE (on) if required.
7. PITOT HEATER — Confirm operation (increase in ammeter load).
8. PART SEP switch (if installed) — As required.

Question 3

Hydraulic system check

Answer 3

1. Collective — Full down.
2. NR — 100% RPM.
3. HYD SYS switch — OFF.
4. HYDRAULIC SYSTEM message — Illuminated.
5. Cyclic — Centered.
6. Cyclic control — Check normal operation by moving cyclic forward and aft, then left and right (approximately 1 inch). Center cyclic.
7. Collective — Check normal operation by increasing collective slightly (1 to 2 inches). Repeat two to three times as required. Return to full down position.
8. Pedals — Check normal operation by displacing pedals slightly (1 inch).
9. HYD SYS switch — HYD SYS (on).
10. HYDRAULIC SYSTEM message — Extinguished.
11. Cyclic and collective friction — Set as desired.

Question 4

Before take off

Answer 4

5. Radio(s) — Check as required.
6. Flight controls — Position and adjust frictions for takeoff.

CAUTION

F A I L U R E T O P O S I T I O N A N D MAINTAIN THROTTLE IN FLY DETENT POSITION PRIOR TO TAKEOFF AND DURING NORMAL FLIG HT OPERATIONS CAN LIMIT AVAILABLE ENGINE POWER.

7. Throttle — Open to FLY detent position. Check 99 to 100% NR/NP.
8. Engine, transmission, and electrical instruments — Within limits.
9. Flight and navigation instruments — Check.
10. FUEL QTY — Note indication.
11. FUEL QTY FWD TANK button — Press, note fuel remaining in forward cell.

Question 5

Engine shutdown

Answer 5

1. Collective — Full down.
2. Cyclic and pedals — Centered and CYC CTR message extinguished.
3. Cyclic friction — Increase so that cyclic maintains centered position.
4. LDG LTS switch — OFF.
5. Throttle — Reduce to idle stop. Check RPM warning light illuminated and audio on at 95% NR.

NOTE

If dual controls are installed, guard throttle to prevent inadvertent manipulation from copilot position.

6. RPM warning light — Press to mute audio.
7. MGT — Stabilize at idle for 2 minutes.
8. ENG ANTI ICE switch — OFF.
9. FUEL BOOST/XFR LEFT circuit breaker switch — OFF.

NOTE

Left fuel boost and transfer pumps will continue to operate until either LEFT FUEL BOOST/XFR circuit breaker switch (highlighted with yellow border) or FUEL VALVE switch is positioned to OFF. These pumps operate directly from battery and will not be deactivated when BATT switch is OFF. Battery power will be depleted if both switches remain on.

10. ELT (if installed) — Check for inadvertent transmission.
11. GEN switch — OFF.
12. FADEC OVSPD TEST button — If required; press, hold 1 second, and release.

Overspeed shutdown test should be accomplished on first engine shutdown of the day. ENGINE OVSPD message will momentarily illuminate in addition to those messages/lights that illuminate during a normal shutdown.

13. IDLE REL switch — Press and hold.

CAUTION

POSITIONING THROTTLE OUT OF CUTOFF DURING NG SPOOL DOWN MAY CAUSE POST ENGINE SHUTDOWN FIRE.

14. Throttle — Closed; check MGT and NG decreasing, ENGINE OUT warning message illuminated and audio on at 55 ±1%.
15. MASTER W/C light — Press to extinguish and mute audio.

CAUTION

AVOID RAPID ENGAGEMENT OF ROTOR BRAKE IF HELICOPTER IS ON ICE OR OTHER SLIPPERY OR LOOSE SURFACE TO PREVENT ROTATION OF HELICOPTER.

16. Rotor brake (if installed) — Apply full rotor brake at or below 40% NR. Return rotor brake handle to stowed position just prior to main rotor stopping.
17. FUEL VALVE switch — OFF.

CAUTION

DO NOT INCREASE COLLECTIVE OR APPLY LEFT TAIL ROTOR PEDAL

18. Pilot — Remain on flight controls until rotor has come to a complete stop.
19. ANTI COLL LT switch — As desired.
20. All remaining overhead switches, except HYD SYS switch — OFF.

NOTE

Ensure engine rotation has completely stopped prior to positioning BATT switch to OFF.

21. BATT switch — OFF, with NG at 0%.

CAUTION

APPLICABLE MAINTENANCE ACTION MUST BE PERFORMED PRIOR TO FURTHER FLIGHT IF A FADEC MESSAGE HAS ILLUMINATED DURING THE PREVIOUS FLIGHT OR ON ENGINE SHUTDOWN.

NOTE

If shutting down at, or refueling to, between approximately 193 to 211 pounds total fuel quantity, up to 18 pounds of fuel may remain in forward fuel cell as unusable.
