1、Designation: F2425 05a (Reapproved 2018)Standard Specification forContinued Airworthiness System for Weight-Shift-ControlAircraft1This standard is issued under the fixed designation F2425; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revi

2、sion, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 The following continued airworthiness requirementsapply for the manufacture of weight-shift-control

3、aircraft andtheir qualification for possible certification.1.2 This specification applies to aircraft seeking civil avia-tion authority approval, in the form of flight certificates, flightpermits, or other like documentation.1.3 This standard does not purport to address all of thesafety concerns, if

4、 any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory requirements prior to use.1.4 This international standard was developed in accor-dance with interna

Safety Directives5.1 A safety directive shall be distributed to all registeredowners and appropriate CAAwhen a condition is found to existthat may also exist in other aircraft in the fleet and

10、 which wouldcause a deviation from original design or unsafe condition forflight, rendering the aircraft unairworthy. This change, main-tenance procedure, inspection procedure, or other proceduresdeemed appropriate by the manufacturer is mandatory andmust be performed and documented in the individua

Such letters areintended to maintain a good rapport with the owners, encour-age feedback on service and other problems, or to circulateitems of

19、 interest that an owner may feel would be of value toother owners. A service letter does not include any mandatoryowner actions.8. 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

20、 exist as a viable business entity, the originalmanufacturer or other responsible organization 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 p

21、hysically safe location. For purposes of thisspecification, a physically safe location is one which is at least33 m (100 ft) from the main production facility, such that a firecould not destroy both sets of records.8.2 Access AssuranceThis documentation shall be avail-able in such a manner that it c

22、an be obtained for commercialuse in the event that existing avenues of recovering theinformation is destroyed. 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

23、of the make and model involved,they may do so by making use of the original manufacturersdocumentation. 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 indust

24、ry entity, for safekeeping. Thelocation and contact for accessing these documents shall bepresented in the AOI, and any revision to this information shallbe disseminated through service bulletins to the aircraft own-ers.8.3 Aircraft Owners Ability to Question a SafetyPublicationAn aircraft owner may

25、 submit written commentsand questions regarding any safety publication to the organi-zation who issued the publication. The issuing organizationmust respond in writing to any such request within 30 days.The request and response must be retained with the records ofthe publication and made available t

26、o any interested party.8.4 Owner Responsibilities:8.4.1 Each owner of a weight-shift-control aircraft shallread and comply with the maintenance and continued airwor-thiness information and instructions provided by the manufac-turer.8.4.2 Each owner of a weight-shift-control aircraft shallprovide cur

27、rent contact information to the manufacturer orCAA which maintains the list of registered owners.8.4.3 The owner of a weight-shift-control aircraft shallnotify the manufacturer of any safety of flight issue orsignificant service difficulty upon discovery. This notificationmust be made in a manner ac

28、ceptable to the manufacturer.8.4.4 The owner of a weight-shift-control aircraft shall beresponsible for complying with all manufacturer issued noticesof mandatory corrective action.9.
