Summary:

During a short flight between the islands of Saint Eustatius and Saint Kitts, Caribbean, the pilot noticed that the ailerons felt “sluggish” but the aircraft landed successfully at Saint Kitts. It was found that a drive rod for the right aileron had broken and a spherical bearing, fitted to one end of the rod, had corroded heavily and was seized. Several safety actions have been taken to reduce the maintenance interval for control rods due to an increased risk of corrosion from the environmental factors where the aircraft operated. This investigation was delegated by the Dutch Safety Board to the AAIB in accordance with paragraph 5.1 of ICAO Annex 13.
