Answer 1

(W) Secure all loose straps to eliminate emergency egress snags.

Question 2

Cockpit Equipment Checks (N)

Answer 2

(N) While fully restrained, the pilot must be able to reach all

• primary flight controls
• propulsion controls
• emergency controls

Question 3

APU CONTR switch - ON (N, N)

Answer 3

(N) If the APU does not start and the APU ACCUM LOW advisory does not appear with the APU CONTR switch ON, a manual start may be attempted.

(N) If the APU fails, note BITE indications before cycling BATT switch or attempting another start.

Question 4

APU generator switch - ON (W)

Answer 4

(W) Clear the stabilator area - the stabilator will move to the full down position.

Question 5

EDECU - Check signal validation code 15 % (C, C, C)

Answer 5

(C) Ensure 0% or 15% is indicated on the TRQ indicator.

If 25% is displayed - do not fly the helicopter.

(C) Contained in statement above.

(C) Contained in statement above.

Question 6

Doppler/GPS - On and program (N)

Answer 6

(N) Only use map datums WGS-84 and NAD-27

*Ft. Rucker: Use map datum 47

Question 7

Caution/advisory/warning panels - check as required (N, N)

Answer 7

(N) If LOW ROTOR RPM is pulsating in DIM mode - Any cautions or advisories may pulsate as well

(N) The lights on the VSI/HSI and CIS may change when testing the caution/advisories lights. Restore changed light afterwards.

Question 8

Flight Controls - Check first helicopter flight of the day (W, W, N)

Answer 8

(W) Ensure no personal gear is interfering with flight control.

Move gear to eliminate restriction of flight controls.

(W) If #1 or #2 PRI SERVO PRESS appears during collective movement, a servo bypass valve may be jammed. If so - Do not fly the helicopter

(N) Maximum 1.5 inches of free play during collective and pedal movement.

Question 9

Stabilator - Check (W, N)

Answer 9

(W) If any part of the stabilator check fails do not fly the helicopter.

(N) Use the right-side STAB POS indicator. The left indicator may vary with +/- 2°

Question 10

Engine(s) - Start (C, N, C, N, C, C)

Answer 10

(C) If start is attempted with ingition switch OFF, do not place switch ON. Abort the start.

(N) Do not use the FUEL BOOST PUMP CONTROL switches to extinguish the #1 or #2 FUEL PRESS lights.

(C) To avoid damage to starter, do not move EPCL from IDLE to OFF while pressing starter button.

(N) If ENGINE STARTER caution disappears with EPCL in OFF, manual press and hold starter until reaching 52-65%.

(C) If starting the engine within an hour of last shutdown, motor the starter for 60 seconds before advancing EPCLs.

(C) Keep cyclic and pedels centered and collective no more than 1 inch above full down until % RPM R reaches minimum 50%

Question 11

Emergency shutdown criteria (abort start)

Answer 11

• No % RPM R within 45 seconds.
• No TGT TEMP increase within 45 seconds.
• No ENG OIL PRESS within 45 seconds.
• ENGINE STARTER caution disappears (before 52% Ng)
• TGT TEMP reaches 851° before idle is attained (63% Ng)

Question 12

Hydrauic leak test system - Check (N, N)

Answer 12

(N) If holding the switch in the test position, the system will not be checked, because the circuits is manual hold open.

(N) If backup pump is still running after test, move BACKUP HYD PUMP switch to OFF and the to AUTO.

Question 13

Tail rotor servo transfer - Check (N)

Answer 13

(N) If BACK-UP PUMP ON or #2 TAIL RTR SERVO ON does not appear, there is a failure in the LDI system.

Question 14

ENG POWER CONT lever(s) - FLY (W)

Answer 14

(W) Restrict rate of EPCL is movement, to avoid helicopter turning.

Question 15

GPS/DPLR NAV MODE selector - As desired (N)

Answer 15

(N) Do not leave the switch in TEST function. This will delete any preprogrammed routes

Question 16

Collective friction - As required (N)

Answer 16

(N) 3 pounds of friction should prevent pilot induced oscillations (PIO) on the collective

Question 17

Operational Engine HIT/ANTI-ICE check - Accomplish (W, N, W, W, C, N)

Answer 17

(W, N, W, W, C) Do not memo - refer to HIT checklist in logbook

(N) Perform HIT check into wind. Reposition helicopter if neccesary.

Question 18

APU CONTR switch - ON (N)

(during parking and shutdown)

Answer 18

(N) If external power is required for shutdown, connect the external power and move EXT PWR switch to reset and then to ON.

If external ac power is not available, complete shutdown on right engine first.

Question 19

Generators NO.1 and NO.2 switches - OFF (N)

Answer 19

(N) When moving EPCL from FLY to IDLE or generator switch is moved to OFF position, an uncommanded right or left pedal drive (1/4 inch) may accour before returing to neutral within 3 seconds.

Question 20

Engine Power Control levers - IDLE (C, C)

Answer 20

(C) Maintain cyclic in neutral position, or slightly into wind, pedel centered, and collective no more than 1 inch above full down position.

(C) Restrict rate of EPCL is movement, to avoid helicopter turning.

Question 21

Droop stops - Verify in, about 50% RPM R (C)

Answer 21

(C) During not increase collective during coast-down to prevent damage of anti-flap stops.

Question 22

ENG POWER CONT levers - OFF after 2 minutes a Ng SPEED of 90% or less. (C, N)

Answer 22

(C) If shutting engine down from high power setting (above 90% Ng) without 2 minutes cool-down, a restart (if needed) should be done within 5 minutes. If restart cannot be done within 5 minutes, the engine should have 4 hours of cool-down

(N) If droops do not go in during shutdown, try following:

1. Shutdown one engine to lower RPM R
2. Accelerate rotor til above 75% RPM R
3. Repeat shutdown while displacing cyclic slightly
4. if droop stops still does not go in, clear rotor disc area and proceed with shutdown
