           Note 4: On the basis of currently available fatigue substantiating data only one spar cap assembly replacement is permitted without further evaluation. This will normally allow only a single life extension from spar cap replacement or reinforcement/modification.

           Note 5: Models not listed in the schedule generally have fatigue lives greater than 30000 hours and are thus unlikely to be affected.

 Compliance: As specified in the Requirement.

           Background:  The retirement lives of this Directive are based directly on data provided by the manufacturer. Amendment 7 was raised to clarify the strap configuration for those models which were fitted with any one of a number of strap configurations during their production life. For all models, the internal straps were fitted to S/N 1731 and subsequent. Amendment 8 corrects some typographical errors.
