## Discrepancy

DURING CRUISE FLIGHT, AP TRIM IS RWD POSTED ON AND OFF EVERY FEW SECONDS. AUTO-PILOT DISCONNECTED.  NOTICED THAT AILERON IS EXTREMELY HARD TO MOVE ALMOST BLOCKED.  IN DESCENT WITHOUT AUTO-PILOT, WE NOTICED THAT THE ELEVATOR ALSO COULD NOT BE MOVED (FL310-300 / SAT -50 C).  AROUND FL290 AND AFTER APPLYING STRONG INPUT, THE AILERON CAME FREE WITH A JERK.  AROUND FL130 (TAT 0C), ELEVATOR FREE AGAIN.  APPROACH AND LANDING NORMAL.  AILERON AND ELEVATOR SERVO MOUNT CHANGED.  OPERATIONAL TESTS ON A/P SERVOS SUCCESSFULLY PERFORMED.  AILERON SERVO CYCLE 18126/ HOURS 23075 ELEVATOR SERVO CYCLE 19592/ HOURS 24455.
