4. Remove the access panel from the bottom of the aft
fuselage. Examine the bellcrank and directional control
hydraulic actuator supports for corrosion and mechanical
damage. Examine the actuator for hydraulic leaks and worn
bearings. Make sure it is correctly attached. (F4)
5. Examine the forward tail rotor driveshaft hanger assembly
for cracks at the mount ears, corrosion or mechanical damage.
Make sure it is correctly attached. Examine the bearing for
discoloration caused by an overheat condition. If applied, check
grease seal to bearing outer race index mark for alignment;
marks must be within 1/8 inch (3.2 mm) of each other. Examine
bearing for any obvious wear or damage and roughness. If any
doubt exists, proceed with inspection of the bearing for
roughness with driveshaft disconnected. (E1/E2)
