Federal Aviation Administration

 
Consensus Standards, Standard Practice for Design, Alteration, 
and Certification of Airplane Electrical Wiring Systems

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability; request for comments.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of consensus standards 
and the Federal Aviation Administration (FAA) intention to accept the 
ASTM International's F2639-07 Standard Practice for Design, Alteration, 
and Certification of Airplane Electrical Wiring Systems (Standard 
Practice) as an acceptable means of compliance to 14 CFR part 23 
sections concerning electrical wiring systems. By this notice, the FAA 
finds the standards to be acceptable methods and procedures for design, 
alteration, and certification of electrical wiring systems for normal, 
utility, acrobatic, and commuter category airplanes.

DATES: Comments must be received on or before October 25, 2010.

ADDRESSES: Comments may be mailed to: Federal Aviation Administration, 
Small Airplane Directorate, Regulations and Policy, ACE-111, Attention: 
James Brady, Room 301, 901 Locust, Kansas City, Missouri 64106 or by e-
mail to: james.brady@faa.gov. All comments must be marked: Consensus 
Standards Comments and must specify the standard being addressed by 
ASTM F2639-07 Standard Practice for Design, Alteration, and 
Certification of Airplane Electrical Wiring Systems.

FOR FURTHER INFORMATION CONTACT: James Brady, Aerospace Engineer, 
Regulations and Policy Office (ACE-111), Small Airplane Directorate, 
Aircraft Certification Service, Federal Aviation Administration, 901 
Locust, Room 301, Kansas City, Missouri 64106; telephone (816) 329-
4132; e-mail: james.brady@faa.gov.

SUPPLEMENTARY INFORMATION: This notice announces the availability of 
consensus standards. The FAA expects a suitable consensus standard to 
be reviewed at least every two years. The two-year review cycle will 
result in a standard revision or reapproval. A standard is issued under 
a fixed designation (i.e., F2639-07); the number immediately following 
the designation indicates the year of original adoption or, in the case 
of revision, the year of last revision. A number in parentheses 
indicates the year of last reapproval. A reapproval indicates a two-
year review cycle completed with no technical changes. A superscript 
epsilon ([epsiv]) indicates an editorial changes since the last 
revision or reapproval. A notice of availability (NOA) will only be 
issued for new or revised standards. Reapproved standards issued with 
no technical changes or standards issued with editorial changes only 
(i.e., superscript epsilon ([epsiv])) are considered accepted by the 
FAA without need for an NOA.
    Comments Invited: Interested persons are invited to submit such 
written data, views, or arguments, as they may desire. Communications 
should identify the consensus standard number and be submitted to the 
address specified above. All communications received on or before the 
closing date for comments will be forwarded to ASTM International 
Committee F39 for consideration. The standard may be changed in light 
of the comments received. The FAA will address all comments received 
during the recurring review of the consensus standard and will 
participate in the consensus standard revision process.
    Background: Under the provisions of the revised Office of 
Management and Budget (OMB) Circular A-119, ``Federal Participation in 
the Development and Use of Voluntary Consensus Standards and in 
Conformity Assessment Activities,'' dated February 10, 1998, industry 
and the FAA have been working with ASTM International to develop 
consensus standards for the design, fabrication, modification, 
inspection, and maintenance of electrical systems installed on normal 
and utility category airplanes.
    These consensus standards satisfy the FAA's goal for airworthiness 
certification and a verifiable minimum safety level for normal, 
utility, acrobatic, and commuter category airplanes. Instead of 
developing airworthiness standards through the rulemaking process, the 
FAA participates as a member of Committee F39 in developing these 
standards. The use of the consensus standard process assures government 
and industry discussion and agreement on appropriate standards for the 
required level of safety.

The Consensus Standards in This Notice of Availability

    The FAA has reviewed the standards presented in this NOA for 
compliance with the regulatory requirements of the rule. Any normal, 
utility, acrobatic, and commuter aircraft issued an airworthiness 
certificate, which has been designed, manufactured, operated, and 
maintained, in accordance with this and previously accepted ASTM 
consensus standards provides the public with the appropriate level of 
safety established under the regulations. The FAA maintains a listing 
of all accepted standards on the FAA Web site.
    The FAA finds the following new consensus standards acceptable for 
certification of the specified aircraft. The consensus standard listed 
below may be used unless the FAA publishes a specific notification 
otherwise.
    ASTM Designation F 2639-07, titled: Standard Practice for Design, 
Alteration, and Certification of Airplane Electrical Wiring Systems.
