Service Letters are issued to explain service policies and introduce new products, or processes approved for Textron Lycoming engines. Service Instructions describe modification, processes and other information pertinent to maintenance repair and overhaul of Textron Lycoming engines. Service Bulletins (published since April 1960) describe mandatory procedures that must be observed for safety reasons, and readily identified by the mandatory heading printed in red. Service Bulletins, Letters and Instructions are available to all from authorized Textron Lycoming distributors, or from the factory; the latest edition of Service Letter No. L114 describes the subscription policy regarding these publications. 1 ALPHABETICAL LISTING OF TEXTRON LYCOMING SERVICE BULLETINS, LETTERS AND INSTRUCTIONS PUB.
