## Discrepancy

HAND FLEW THE ENTIRE FLIGHT WITH NO AUTOPILOT AND REQUIRED 3 DEGREES OF AILERON TRIM UPON FURTHER INVESTIGATION, PER MEL 27-13-2-0-1 AILERON DEFLECT INOP IS NOT TO BE DISPLAYED PRIOR TO BREAKER LOCKOUT AND ALLOWABLE DEFLECTION A NEUTRAL MUST BE 0 PLUS OR MINUS 1. FOUND AILERON DEFLECT INOP MESSAGE DISPLAYED AND INDICATED DEFLECTION OF LT O/B AILERON TO BE 6.875 DEGREES. THIS IS THE CAUSE FOR TRIM.
