Factual narrative
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.
