Light-sport category aircraft certificated pursuant to 14 CFR part 21, section 21.190 have mandatory compliance with all manufacturer safety directives. service Bulletins A service bulletin contains a recommendation from the manufacturer, with which that manufacturer believes the aircraft owner should comply, that often reflects a safety-of-flight issue that the manufacturer believes should be addressed within a certain time- frame. It may result from an improvement developed by the manufacturer, or it may address a defect in a product or published documentation. The manufacturer responds to one of these situa-tions by issuing a service bulletin that recommends a certain type of inspection, replacing certain components, performing maintenance in a specific manner, or limiting operations under specified conditions. Sometimes, compliance with a service bulletin may be triggered by the occurrence of a particular event (e.g., the lapse of time or operation under certain types of conditions). FAA Form 337, major repair and Alteration A mechanic who performs a major repair or major alteration shall record the work on FAA Form 337 and have the work inspected and approved by a mechanic who holds an inspection authorization (IA). (Light-sport aircraft do not require Form 337 when altering a non-approved product.) A signed copy shall be given to the owner and another copy sent to the FAA Aircraft Registration Branch (AFS-750) in Oklahoma City, Oklahoma within 48 hours of aircraft approval for return to service. However, when a major repair is done by a certificated repair station, the customer’s work order may be used and a release given as outlined in 14 CFR Part 43, Appendix B, Recording of Major Repairs and Major Alterations. You can obtain additional information and instructions for completing FAA Form 337 in Advisory Circular (AC) 43-9 (as revised), Aircraft Maintenance Records. Figure 8-2 at the end of this chapter is a sample FAA Form 337. 中国通航网 www.ga.cn 通航翻译 www.aviation.cn 本文链接地址：Plane Sense General Aviation Information 通用航空信息 2(25) |
