Advisory Circular 36-4C, Noise Standards: Aircraft Type and 
Airworthiness Certification

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability.

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

SUMMARY: The Federal Aviation Administration (FAA) is publishing a 
notice of availability of the draft advisory circular on ``Noise 
Standards: Aircraft Type and Airworthiness Certification.'' This notice 
is intended to assist interested persons who are reviewing a notice of 
proposed rulemaking on noise certification standards for subsonic jet 
airplanes and subsonic transport category large airplanes that is 
currently out for public comment. It also solicits comments on this 
draft circular.

DATES: Comments must be received on or before October 10, 2000.

ADDRESSES: Copy of the draft AC 36-4C may be obtained on the FAA's web 
site (http://www.aee.faa.gov/ac-36-4c), or by mail by contacting the 
Office of Environment and Energy at the address listed in the FOR 
FURTHER INFORMATION CONTACT section.

FOR FURTHER INFORMATION CONTACT: Mr. Thomas L. Connor, Noise Division 
(AEE-100), Office of Environment and Energy, FAA, 800 Independence 
Avenue, SW., Washington, DC 20591; telephone (202) 267-8933.

SUPPLEMENTARY INFORMATION: The draft Advisory Circular (AC) 36-4C, 
``Noise Standards: Aircraft Type and Airworthiness Certification'' 
contains information concerning the standards and requirements for 
aircraft noise certification and presents explanatory information, as 
necessary, to identify acceptable means of compliance.
    The draft AC contains a section-by-section review of the 14 CFR 
part 36. The draft AC presents acceptable noise certification 
procedures for normal, utility, acrobatic, and commuter

category small airplanes, transport category airplanes and normal and 
transport category rotorcraft.
    The FAA recently proposed changes to the noise certification 
standards for subsonic jet airplanes and subsonic transport category 
large airplanes that were published in the Federal Register in a notice 
of proposed rulemaking (65 FR 42796, July 11, 2000). The comment period 
closes on October 10, 2000. These proposed changes are based on the 
joint effort of the FAA, the European Joint Aviation Authorities, and 
Aviation Rulemaking Advisory Committee, to harmonize the U.S. noise 
certification regulations and the European Joint Aviation Requirements 
for subsonic jet airplanes and subsonic transport category large 
airplanes. The draft AC 36-4C, ``Noise Standards: Aircraft Type and 
Airworthiness Certification'' is referred to in the above NPRM and, 
therefore, the draft AC is being made available by the FAA to review in 
conjunction with this NPRM. Comments are invited on the draft AC and 
should be submitted along with comments on the companion NPRM through 
the NPRM docket (Docket No. FAA-2000-7587).
    The FAA intends to issue the final AC 36-4C concurrently with the 
final rule on the noise certification standards for subsonic jet 
airplanes and subsonic transport category large airplanes.

    Issued in Washington, DC, on August 2, 2000.
James D. Erikson,
Director of Environment and Energy.
