            Applicability: All model 369 series helicopters, fitted with a driveshaft coupling within the S/N range 5200 thru 5309.

            Requirement: Action in accordance with McDonnell Douglas SIN No HN-216, DN-157, EN-47 or FN-35, as applicable. If the S/N cannot be identified the coupling must be replaced unless its history is known and can be tracked to delivery. McDonnell Douglas will advise S/N fitted to specific aircraft at delivery upon request.

            Compliance: At next periodic inspection for issue of a Maintenance Release or by 15 August 1989, whichever occurs first.

            Background: Due to possible cracking of the transmission driveshaft coupling a one time inspection of the coupling serial number against the serial number listing contained in the compliance document is required.

            This Amendment clarifies Requirements for those couplings that have lost the S/N decal.
