Service bulletin changes are notmandatory to maintain the aircrafts compliance with ASTMstandards.7. Service Letter Documents7.1 The manufacturer should issue

16、 service letters on anysubject that is considered helpful to the owners. Such letters areintended to maintain a good rapport with the owners, encour-age feedback on service and other problems, or to circulateitems of interest that an owner may feel would be of value toother owners. A service letter

Continuation of Airworthiness8.1 Copies MaintainedIn order to help insure that the fleetof aircraft remains airworthy even after the original manufac-turer has ceased to exist as a viable business entity, the originalmanufacturer or other responsible or

18、ganization shall maintaindocumentation on file showing compliance with applicablespecifications. This documentation showing compliance withthe standards and any “safety of flight” shall be copied andmaintained at a physically safe location. For purposes of thisspecification, a physically safe locati

This documentation shall be retainedeven after the original manufacturer ceases business activity,such that in the event that a future entity wishes to continuesupporting the airworthiness of the make and model involved,they may do so by making use of the original manufact

21、urersdocumentation. The original manufacturer may either keepthese documents on file such that they will be available at anyfuture date, or shall turn them over to a responsible agencysuch as the FAA, or other industry entity, for safekeeping. Thelocation and contact for accessing these documents sh
