Startup and Shutdown- W, C, N

Warning- Stabilator will move to full trailing edge down position upon application of AC power. Assure stabilator area is clear prior to energizing stabilator system.

Note- Only use map datum WGS-84 and NAD-27
Use map datum 47. Ref pg 3-73 (-10)

Note
Pulsating of any cautions or advisories with the LOW ROTOR RPM warnings may occur in DIM mode

Note
The switch legend on the VSI/HIS and the CIS mode select panel may change when the caution/advisory panel BRT/DIM – TEST switch is set to TEST. This can also occur in flight. The original indications may be restored by pressing the applicable switches

Warning - Prior to flight, the user must perform control sweeps to ensure that there are no flight control interference problems with aviator worn gear. If a restriction is found, the interfering gear must be adjusted/moved to eliminate the restriction

Note- The force applied to the pedals with SAS and BOOST off during pre-flight checks should be limited to only that required to contact a system stop.

Warning- If #1 PRI SERVO PRESS or #2 PRI SERVO PRESS caution appears during collective movement, a servo bypass valve may be jammed. If the situation occurs, do not fly the helicopter

Note- During collective and pedal movement, check for not more than 1.5 inches of free play in control

Warning- If any part of stabilator check fails do not fly helicopter

Note- For the purpose of this check, the right STAB POS indicator shall be used. The left STAB POS indicator may vary from right indicator as much as +/- 2 degrees throughout the check

Caution- If start is attempted with ENGINE IGNITION switch OFF, do not place switch ON. Abort the start

Note- During engine start, the #1 or #2 FUEL PRESS cautions may appear briefly. The FUEL BOOST PUMP CONTROL switches shall not be used to extinguish the #1 or #2 FUEL PRESSURE cautions during an engine start sequence

Caution-To avoid damage to the engine start switch actuators, do not move the ENG POWER CONT lever from IDLE to OFF while pressing the starter button

Caution-During engine start and run up, ensure that cyclic is kept in neutral, collective no more than one inch above full down and pedals centered until %RPM R reaches 50% minimum to prevent damage to anti-flap bracket bushing

Note- If an ENGINE STARTER caution disappears when the starter button is released, and the ENG POWER CONT lever is OFF, the start attempt may be continued by pressing and holding the starter button until 52% to 65% Ng SPEED is reached; the release the button

Note- When performing the HYD LEAK TEST, all leak detection/isolation system components are checked electrically. Manually holding the HYD LEAK TEST switch in the test position does not allow the leak detection/isolation system to be checked automatically. It manually holds the circuits open. The switch must be placed in the TEST position and released

Note-If the backup pump is still running following the hydraulic leak test, cycle the BACKUP HYD PUMP switch to OFF then back to AUTO

Note - Failure of the BACK–UP PUMP ON advisory or the #2 TAIL RTR SERVO ON advisory to appear indicates a failure in the leak detection/isolation system

Warning- Restrict the rate of ENG POWER CONT lever’s movement, when the tail wheel lock pin is not engaged. Rapid application of ENG POWER CONT levers can result in turning the helicopter, causing personnel injury or loss of life

Note- If a consecutive or random route was programmed, do not allow the system to perform the test function. Performing the test function will delete any preprogrammed routes

Note- A slight amount of collective friction (approx 3 pounds) should be used to prevent pilot induced collective oscillations

Warning- Fuel Boost Pump control switches shall remain on during all pressurized fuel transfer operation and remain on for 10 minutes after transfer operation have ceased. Failure to observe this warning may cause engine flameout

Warning- Engine anti-ice bleed and start valve malfunction can cause engine flameout

Note- Refer to HIT Test/Anti Ice check in helicopter log book. HIT/Anti Ice checks while operating in adverse conditions (e.g. dust, desert, coastal beach area, dry river beds) may be deferred (max of 5 flight hours) until a suitable location is reached.

Note
If the helicopter is equipped with two FAT gages and the readings are different, the higher reading will be used
Warning- Do not cycle anti-ice bleed and start valve more than once. Valve malfunctions can cause engine flameout at low power settings or during rapid collective movements. Do not fly the aircraft if the ENG ANTI – ICE advisory will not disappear 

Note
A malfunctioning engine anti-ice and engine anti-ice system may result in power losses as much as 40% less in the 30 minute max torque available. If any part of the engine anti ice check fails, do not fly the helicopter
Note
When using the HIT table, round FAT up and pressure altitude to nearest value

Caution- During shutdown ensure that cyclic is kept in neutral or displaced slightly into prevailing wind, collective no more than one inch above full down and pedals centered

Caution- Restrict the rate of PCL movement, when the tail wheel lock pin is not engaged. Abrupt application of PCL can result in turning the helicopter
Note- AHRS During shutdown, when PCL’s are moved from FLY to IDLE position, or generator switch is moved to OFF position, and electrical power assignment is changed from main gen to APU gen. An uncommanded right or left pedal drive of up to ¼ inch may occur, returning to neutral position within 3 seconds

Caution
To prevent damage to anti-flap stops, do not increase collective pitch at any time during rotor coast-down

Caution- Before moving PCL OFF, engine must be cooled for 2 minutes at an Ng Speed of 90% or less. If an engine is shut down from a high power setting (above 90%) without being cooled for 2 minutes, and it is necessary to restart the engine, the restart should be done within 5 minutes after shutdown. If the restart cannot be done within 5 minutes, the engine should be allowed to cool for 4 hours before attempting an engine restart
