This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Discussion of Comments
A notice of proposed policy was published in the Federal Register on May 30, 2003 (68 FR 32570). Five (5) commenters responded to the request for comments.
The policy provides applicants with information on how the FAA will evaluate petitions for exemption from § 25.841(a), as amended by Amendment 25-87. For airplanes with wing-mounted engines, this regulation in effect limits the maximum operating altitude of airplanes approved to this standard to 40,000 feet. An Aviation Rulemaking Advisory Committee (ARAC) recommended that the FAA to develop a new safety standard, which is being addressed in rulemaking activities. That committee also asked for interim policy to be used during the rulemaking process, to provide relief because high altitude operations offer benefits in terms of reduced fuel consumption and better airspace utilization. This policy applies to the regulatory provisions regarding cabin pressure failures caused by uncontained engine failures. This policy does not provide relief from the regulatory cabin pressure limits for the more common types of failures (i.e., environmental systems and structural failures).
The final policy as well as the disposition of public comments is available on the Internet at the following address: http://www.airweb.faa.gov/rgl.
