Must complete air rudder removal and elevator pushrod removal in order before completing the hori-
zontal tail removal. (See “Air Rudder Removal” on page 12-9.)(See “Elevator Pushrod Removal” on page
12-10.)
TASK INSTRUCTIONS:
1. Prepare a way to support the horizontal tail just above the vertical tail once the two are sepa-
rated. This can be with padded scaffolding, ladders, or with two helpers.
2. Remove the forward ME000640 surface plug at the top right side of the vertical tail tip.
3. Remove the safety wire from the heads of the aft vertical tail/horizontal tail attach bolts.
4. At the forward vertical tail/horizontal tail attach, accessed through the forward access hole on
the right side of the vertical tail tip, remove the AN4C10A bolt and NAS1149C0432. The bolt
threads into a nutplate.
5. Remove the two AN4CH10A drilled-head bolts and NAS1149C0432 washers from the aft vertical
tail/horizontal tail joint. These bolts thread into nutplates in the vertical tail spar.
CAUTION: The horizontal tail will not be attached at this point.
6. Carefully raise the horizontal tail a few inches above the vertical tail, feeding the two wire
harnesses through the vertical tail tip rib to gain slack. Support the horizontal tail in the position.
7. Disconnect the multi-pin wire connector and coaxial cable connectors at the vertical tail/hori-
zontal tail joint.
8. Remove the horizontal tail.
VERIFICATION METHOD:
Once horizontal tail is completely detached from the aircraft, this task is complete.
