    Discussion
    
        This advisory circular applies to Part 25 of the Federal Aviation 
    Regulations for transport category airplanes for which a new, amended, 
    or supplemental type certificate is requested. The policy extracts 
    contained in the AC are presented in order to provide guidelines which 
    can help in understanding and resolving certification issues or making 
    approval decisions. In the past, advisory and guidance information 
    applicable to transport airplane electrical systems and equipment 
    installations has been formally published within ACs. However in many 
    instances policy has been developed and applied to specific 
    certification projects without formal publication. This policy was 
    documented in the form of policy memorandums, issue papers which were 
    distributed to the FAA Aircraft Certification Offices, or in the form 
    of letters sent to commercial companies, other U.S. government 
    agencies, U.S. Congressional representatives, or foreign certification 
    and airworthiness authorities. In many instances this information was 
    not organized in a way that allowed easy access. This AC is intended to 
    document existing policy so that the public and FAA personnel have 
    access to this information. The excerpts from memoranda and letters 
    provided in this AC represent historical views of regulations and 
    requirements which may have evolved since the issue of policy in the 
    extract, and may be applicable to a specific airplane model depending 
    on the certification basis. The applicant and the cognizant 
    certificating authority are advised to check and ensure, at the 
    earliest practical moment, that a specific policy extract applies to 
    any specific airplane type certification programs.
    
        Issued in Renton, Washington, on September 8, 1998.
