Aircraft Electrical Load and Power Source Capacity Analysis

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability; request for comments.

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

SUMMARY: This notice announces a Federal Aviation Administration (FAA) 
proposed policy on recognizing ASTM International's F2490-05 Standard 
Guide for Aircraft Electrical Load and Power Source Capacity Analysis 
as an acceptable means of compliance to 14 CFR part 23, 23.1351(a)(2). 
The Standard Guide provides acceptable methods and procedures to 
determine electrical system capacity needed to provide worst-case 
combinations of electrical loads during all phases of airplane 
operations. This notice is necessary to advise the public of this FAA 
policy and give all interested persons an opportunity to present their 
views on it.

DATES: Comments must be received on or before May 12, 2006.

ADDRESSES: Mail comments to: Federal Aviation Administration, Small 
Airplane Directorate, Continued Operational Safety, ACE-113, Attention: 
Barry Ballenger, Room 301, 901 Locust, Kansas City, Missouri 64106. 
Specify the standard being addressed by ASTM designation and title and 
mark all comments: Consensus Standards Comments.

FOR FURTHER INFORMATION CONTACT: Barry Ballenger, Aerospace Engineer, 
Continued Operational Safety Branch (ACE-113), Small Airplane 
Directorate, Aircraft Certification Service, Federal Aviation 
Administration, 901 Locust, Room 301, Kansas City, Missouri 64106; 
telephone (816) 329-4152; e-mail: [email protected].
    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. 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

    The FAA finds the following new consensus standard acceptable for 
normal and utility, acrobatic, and commuter category airplanes. The 
consensus standard listed below may be used unless the FAA publishes a 
specific notification otherwise.
    a. ASTM Designation F 2490-05, titled: Standard Guide for Aircraft 
Electrical Load and Power Source Capacity Analysis.
