Task Instructions
1. Remove horizontal tail tips.
a. Pull downward on the tip lock latch to remove it from the detent position and rotate the latch approximately 180°.
b. Grasp the tip and slide it away from main horizontal tail until the cylindrical spar clears the structure.
2. Check horizontal tail for binding or interference with vertical tail in forward-aft direction by applying 10-15 lbs of load to the outboard side of horizontal tail forward and aft.
The joint between the vertical tail and the horizontal tail should maintain form and gapping as well.
3. Check horizontal tail for binding or interference in up-down direction by applying 5-10 lbs of load to the outboard side of tail up and down.
The joint between the vertical tail and the horizontal tail should maintain form and gapping as well.
4. Install horizontal tail tips and repeat play steps 2 and 3.
a. Grasp the tip and slide the cylindrical spar fully into the main horizontal tail taking care that the locating pin near the leading edge aligns properly. Ensure that the tip is fully engaged by pressing it firmly into position.
b. Rotate the latch back into the locked position ensuring that it snaps upward into the detent position.
c. With the master switch on, verify that the ‘SECURE WING/TAIL’ light on the annunciator panel has extinguished.
Warning:
The latch for the removable horizontal tail tip must fully cover the red portion of the placard in order for the tail to be locked. An annunciator panel light in the cockpit will warn the pilot when either of the tips is unlocked or not installed correctly.
5. Examine the tips and tail for excessive play. Tips should feel secure without relative motion to the tail.
Verification Method
Confirm results are within acceptable limits.
