Task Instructions
1. Pull downward on the tip lock latch to remove it from the detent position and rotate the latch approximately 180°.
2. Grasp the tip and slide it away from main horizontal tail until the cylindrical spar clears the structure.
3. Support the horizontal tail tip on a soft protective surface.
4. Inspect the minimum pin diameter of the two anti-rotation pins that protrude from the surface of the tip’s root rib. Inspection can be completed with a micrometer and caliper.
Figure 207. Anti-Rotation Pins
Note:
Pin diameter measurement needs to be taken on the circular surface of the pin, avoiding the flats used for removal.
Verification Method
Record results and check that wear is within these limits. Replace if outside limit (Horizontal Tail Tip Pin)
Minimum pin diameter =.240”
