If free play exceeds 0.125 inches, inspect and replace worn travel control arm assembly (P/N 96220-00) and check rudder trim barrel (P/N 96596-00) for end play, shimming as needed. After adjustments, re-check free play. Repeat inspections every 100 hours time in service unless modified with P/N 760800V.
