What was found
(CAN) DURING LANDING PHASE AIRCRAFT ROLLED TO LT WHEN APPROACH FLAPS WERE SELECTED. ROLL RESPONSE WAS CORRECTED WITH AILERON TRIM INPUT. FURTHER FLAP DEPLOYMENT DID NOT CREATE ANY FURTHER CONTROL DIFFICULTY. MAINTENANCE INSPECTED AIRCRAFT AND DISCOVERED THAT THE RT OUTER FLAP WAS NOT SYMETRICAL TO OTHER FLAPS. THE IB FLAP HANGAR HAD CHANGED POSITIONS DUE TO A CRACK IN THE REAR SPAR WEB AT THE FLAP HANGAR ATTACH POINT. SEVERAL OTHER ANGLES AND BRACKETS WERE ALSO BROKEN. A REPAIR SCHEME WAS REQUESTED FROM MFG.
