C. Rigging and Adjustment
CAUTION: VERIFY FREE AND CORRECT MOVEMENT OF RUDDER. WHILE IT WOULD SEEM
SELF-EVIDENT, FIELD EXPERIENCE HAS SHOWN THAT THIS CHECK IS
FREQUENTLY MISINTERPRETED OR NOT PERFORMED AT ALL. ACCORDINGLY,
UPON COMPLETION OF RUDDER TRIM RIGGING AND ADJUSTMENT, VERIFY
THAT THE RUDDER MOVES LEFT WHEN THE RUDDER TRIM WHEEL IS
TRIMMED LEFT; AND, THAT THE RUDDER MOVES RIGHT WHEN THE RUDDER
TRIM WHEEL IS TRIMMED RIGHT.
No adjustments are necessary other than those required during installation of the assembly in the
airplane as given in Rudder Trim Controls - Installation, above.
