Tail rotor control rod at gearbox and pitch control links at rotor for
excessive bearing play, free movement and security. Pitch control for
evidence of seal rotation or loss of grease.
Tail rotor teeter bearings for axial or radial play.
Overrunning clutch for proper operation; turn rotor in forward
direction, by hand - engine must decouple; turn rotor in reverse
direction - engine must rotate (listen for turbine noise during rev erse
rotation).
NOTE:
Normal seal drag may be sufficient to rotate engine at low
RPM.
Drive fork for failure between metal cones and elastomeric elements
in bearing assembly. Apply teetering force by hand (stop-to-stop) to
rotate blades. Inspect elastomers for radial molded ridges on each
bearing face as teetering takes place. Discontinuity in molded ridges
indicates bearing failure.
NOTE:
Light swelling, pock marks and crumbs are surface
conditions and do not indicate b earing failure.
ENGINE COMPARTMENT
Rear cross beams for yielding (evidence of hard landing).
Fuel cell for leakage and security.
Drain fuel sample from fuel cell sump drain valve into suitable
container. Check for water and/or contaminants in fuel sample. If
fuel is contaminated, refer to Rolls Royce Operation and
Maintenance Manual, Publication No. 10W2 for corrective action,
prior to flight.
Check fuel cell sump drain valve and bottom of fuselage for
evidence of leakage.
Check engine oil level; replenish if low.
Battery clean and secure.
