Analysis

The plt reported that during arrival to the destination arpt, he heard a loud bang & the acft began rolling to the right. He reported that he was unable to control the roll with the ailerons, so he reduced power on the left eng & applied left rudder. The crew was then able to maintain directional control of the acft & made a safe landing. After landing, the left aileron was found to be bent at the 2nd hinge point. An investigation revealed that on 2/20/84, the screws on the outboard hinge of the left aileron were improperly installed. This allowed the outboard section of the aileron to come loose.
