Always ask the question: "Does the logbook reflect what has actually been done to the airplane?" If so, then the owner should have confidence that the logbooks are reasonably accurate. If the logbook contains maintenance or alteration actions that are currently not part of the airplane, then further investigation may be in order to determine the importance of the missing action. Likewise, if the airplane is altered without any logbook entries, then you should investigate the alterations to determine the effect on the performance of the airplane. B. Aircraft Records: The FAA provides records for specific aircraft, propellers, and engines. By sending a request to the FAA with the aircraft N number, an owner can receive a copy of all the records on that particular aircraft. Because airplane N numbers can change, you should also make a similar request for aircraft make, model, and serial number. If these two do not match, then you may need to further investigate as to why. Records available include registrations, bills-of-sale, repair and alteration form 337s, supplemental type certificates (STC), and other information. You should also compare this paperwork to the physical airplane to determine if any unrecorded modifications have been made. These records are sent either on microfiche, on CD, or on paper for some older aircraft. There is a nominal charge to open the aircraft file and copy the material. Information regarding records requests is available from the FAA at Flight Standards Service (AFS-750), Box 25504, Oklahoma City, OK 73125 or at the following website: http://diy.dot.gov. C. Type Certificate Data Sheets (TCDS): The TCDS contains relevant data specific to a model type. The FAA awards a type certificate (TC) only after the applicant shows compliance with the safety regulations as specified by the certification basis listed on the TCDS. The TCDS is a summary of the baseline technical description of the model type, which includes information such as performance, weights, center of gravity limits, and engine and propeller specifications. You can access the TCDS database at the following FAA website: http://www.airweb.faa.gov/rgl or by clicking the following hotlink: type certificate data sheet. 中国通航网 www.ga.cn 通航翻译 www.aviation.cn 本文链接地址：Best Practices Guide for Maintaining Aging General Aviation Airplanes(5) |
