Subject: Use of ARAC Transport Airplane and Engine Subcommittee (TAE) recommended rulemaking not yet formally adopted by the Federal Aviation Administration (FAA) as a basis for an equivalent level of safety finding or an exemption to part 25.

Background: Applicants in a number of active certification projects propose to adopt draft FAA/European Aviation Safety Agency (EASA) harmonized regulations into their certification bases. To address this issue, the Transport Airplane Directorate issued a policy memo titled: "INFORMATION: 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," dated January 4, 2001. The memo describes a standardized, streamlined approach for the use of draft FAA/JAA (now EASA) harmonized regulations as a basis for an equivalent safety finding (EFS) (or, in some cases, an exemption) to part 25.

  • List of Part 25 Rules with ARAC Recommendations Eligible for ESF or Exemption
  • Some recommendations from the working groups are for advisory material only, and do not propose changes to the regulations. The draft advisory material, in these cases, may be proposed as an acceptable method of compliance. Obtaining FAA acceptance of these draft advisory materials as an acceptable means of compliance would be accomplished through the existing certification processes.

    Please note that the information in this webpage was developed in consideration of all the part 25 recommendations that the FAA has received as of 7/17/2013. This website will be updated periodically to remove those recommendations that have been formally adopted by the FAA as an amendment to 14 CFR part 25 and consider additional recommendations forwarded to the FAA. If you have any questions regarding the information on this website, please contact James Wilborn or Mel Johnson of the Transport Airplane Directorate.
