ROTOR RPM (N

) – Set to 100%

Cyclic – Centered, friction removed.

Hydraulic System – Check as follows:

HYDR SYS NO. 1 switch – OFF. Check MASTER CAUTION light illuminates

and #1 HYDR SYST caution light illuminates. Hydraulic system no. 1

pressure decreases.

Cyclic – Check normal operation by moving cyclic in an “X” pattern, right

forward to left aft, then left forward to right aft (approximately 1 inch). Center

cyclic.

Collective – Check normal operation by increasing collective slightly (1 to 2

inches). Return to down position.

Note

Boost for tail rotor controls is furnished by hydraulic

system no. 1 only. When hydraulic system no. 1 is being

checked, tail rotor controls will be unboosted.

Pedals – Displace slightly left and right. Note an increase in force required to

move pedals.

Warning

DO NOT TURN BOTH HYDRAULIC SYSTEMS OFF AT

SAME TIME DUE TO EXCESSIVE FORCE REQUIRED

TO MOVE FLIGHT CONTROLS.

extinguishes and hydraulic system no. 1 pressure returns to normal. #1
