Preflight Checklist (continued)
18. Disengage the rotor brake. Verify full forward,
aft, left and right travel in cyclic. Verify both cyclics
move together and are not obstructed.
19. Check rotor head. From the rear of the aircraft,
pull on the rotor, push on the rotor and check for any
play in the bearings. Rotate the rotor clockwise and
counter-clockwise and check for play in the torque
tube bushings. Give the rotor blade a gentle push
and watch the tip as it moves around 180 degrees.
Repeat for the other rotor. Any “jump” in the travel
or noise could signify main rotor bearing damage.
20. Re-engage rotor. Check rotor trim setting.
21. Walk around body and verify all body connecting
screws, windshield screws and access panel screws
are installed and tight.
22. Check seat belts. Secure rear seat belts and
seat pad if not carrying a passenger.
23. If required, check landing lights, strobes and
position lights.
