## Discrepancy

AT T/O WITH FLAP 20 DEGREES THE YOKE WOULD STICK AT ABOUT THE POINT OF 2 UNITS OF RIGHT AILERON TRIM.  AFT FLAP WERE AT 10 DEGREES THE YOKE WOULD STICK AT THE SAME POINT, BUT TAKE LESS PRESSURE TO OVERCOME THE PROBLEM, ON APPROACH NO INDICATION OF STICKING WITH FLAPS UP OR AT NIL FLAPS SETTING DOWN TO 30 DEGREES.  VERIFIED YOKE AND AILERONS, NOT BINDING PRIOR TO DEPARTURE WITH FLAPS UP AND FLAPS DOWN IAW MM 27-11-00.
