PROCEDURE
1.
Turn the Master switch ON.
2.
Trim the trim tab to the maximum down deflection (i.e. the aircraft will pitch up in flight).
3.
Turn the Master switch OFF.
4.
Loosen the lock nut (1), i.e. screw it backward on the threaded rod (2), away from the eye-
bolt (3).
5.
Remove the split pin, pin and washer (4) and disconnect the eye-bolt from the trim tab horn (5).
6.
Adjust the eye-bolt on the threaded rod, temporarily reattach to the trim tab horn and measure
the trim tab deflection downwards relative to the elevator upper surface (use a protractor or
measure the downward displacement of the trim tab trailing edge). Repeat step 4 until the
deflection measures equal to 25°.
7.
Do not reuse split pin. Fit new. Note that the pin is inserted with the split pin and washer facing
towards the aircraft fuselage.
8.
Tighten the lock nut against the eye-bolt.
9.
Before flight, verify correct operation and travel (refer to paragraph 1.13) of the elevator trim tab.
