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.

Manager, Transport Airplane Directorate, Aircraft Certification
Service, ANM-100.
