King Airs are equipped with a right hand and left hand aileron, which is a flight control surface found on the trailing edges of each fixed wing. The ailerons work together to control the aircraft's roll. Part number 101-130001-626 is the manufacturer's spare for a right hand aileron on the King Air B200 aircraft model. The alternate and spare part numbers will vary based on the plane's serial number. Call us for exchange or repair options. Our on-site repair shop has approved capabilities on all flight control surfaces.
