The pilot lowered the flaps to 35 degrees while on final approach to runway 21. He noted aileron binding as the flaps traveled to 35 degrees, and at the same time heard a snap under the floor of the cockpit. After landing the flaps were not retracted. The airplane was taxied to the terminal where it was observed that the right outboard flap panel had became detached from the flap aft roller bearings at the inboard flap track. The flap was in contact with the aileron, which interfered with aileron control. The manufacturer had published a Safety Communique during May 1997. The Communique dealt with the inspection of the outboard flap attachment brackets and aft roller bearings of Beech 1900 series airplanes. The incident airplane was scheduled to have the inspection complied with during the next 30 days. The airplane had accumulated about 3,317 flight hours and 7,069 landings. An inspection of the remainder of the operator's fleet of Beech 1900D airplanes revealed that eight additional airplanes failed the inspection criteria, but had not reached the assigned number of cycles specified in the Communique.
Probable Cause: The right outboard flap detaching from the flap aft roller bearings, at the flap track, which was a result of the manufacturer's inadequate inspection program.
