System Design Analysis; Proposed Changes to Airworthiness 
Standards and Advisory Circular

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of availability of Aviation Rulemaking Advisory 
Committee (ARAC) recommendations.

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

SUMMARY: The Federal Aviation Administration (FAA) announces the 
availability of the ARAC-recommended proposed changes to the 
airworthiness standards for transport category airplanes regarding 
equipment, systems, and installations, and Advisory Circular (AC) 
25.1309-1A, ``System Design Analysis,'' for potential use, upon 
request, in the certification of applicable airplane systems. The FAA 
has not yet adopted these ARAC recommendations.

FOR FURTHER INFORMATION CONTACT: Mr. Linh Le, Federal Aviation 
Administration, Transport Airplane Directorate, Transport Standards 
Staff, Safety Management Branch, ANM-117, 1601 Lind Avenue SW., Renton, 
WA 98055-4056; telephone (425) 227-1105; fax (425) 227-1320; e-mail: 
[email protected].

SUPPLEMENTARY INFORMATION: Reference: FAA policy memorandum 00-113-1034 
``Use of ARAC (Aviation Rulemaking Advisory Committee) Recommended 
Rulemaking not yet formally adopted by the FAA, as a basis for 
equivalent level of safety or exemption to Part 25.''
    This policy memorandum describes a standardized, streamlined 
approach for the use of draft FAA/JAA harmonized regulations as a basis 
for an equivalent level of safety finding or an exemption to part 25. 
It may be found on the Internet at the following address: http://www.faa.gov/certification/aircraft/anminfo/document/final/aracesf/index.htm.

Background

    After a multi-year review of the current Sec.  25.1309 and AC 
25.1309-1A, the ARAC submitted to the FAA their recommendations for a 
rule change and a revised advisory circular in August 2002. The ARAC-
recommended proposed changes to 14 CFR 25.1309 and AC 25.1309-1A are 
available on the Internet at the following address: http://www1.faa.gov/avr/arm/aractransairengine.cfm?nav=6. If you do not have 
access to the Internet, you can obtain a copy of the policy by 
contacting the person listed under FOR FURTHER INFORMATION CONTACT.
    The procedure for using ARAC recommendations for rule changes that 
are not yet adopted by the FAA is described in the FAA policy 
memorandum 00-113-1034 referenced above. The memorandum describes the 
process for requesting an equivalent safety finding, as well as 
petitioning for an exemption.
    A specific portion of the proposed changes to AC 25.1309-1A that 
should not be used as an acceptable means of compliance is paragraph 
8.d, which describes an alternative method of compliance by exemption. 
The FAA does not concur with paragraph 8.d and intends to exclude 
paragraph 8.d from the final AC. The remainder of the proposed changes 
to the AC may be used as an acceptable means of compliance to the 
proposed revision to Sec.  25.1309, or to the existing Sec.  25.1309.

    Issued in Renton, Washington, on April 14, 2003.
Mike Kaszycki,
Acting Manager, Transport Airplane Directorate, Aircraft Certification 
Service.
