Civil Supersonic Airplane Noise Type Certification Standards and 
Operating Rules

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: The Federal Aviation Administration (FAA) is withdrawing a 
previously published Notice of Proposed Rulemaking (NPRM) that proposed 
to amend the Federal Aviation Regulations to revise the airplane type 
certification standards and operating rules. The proposed amendments 
would have required that future civil supersonic airplanes meet noise 
limits consistent with those required for future civil subsonic 
airplanes. The FAA is postponing development of a final rule because it 
cannot ensure that the final rule would be economically reasonable and 
technologically practical at this time. The FAA will continue to gather 
technical information and analyze suggested recommendations for test 
and measurement conditions.

FOR FURTHER INFORMATION CONTACT: Ms. Laurette Fisher, Policy and 
Regulatory Division (AEE-300), Office of Environment and Energy, 
Federal Aviation Administration, 800 Independence Avenue, SW., 
Washington, DC 20591, telephone (202) 267-3561.

SUPPLEMENTARY INFORMATION: On October 30, 1986, the FAA published 
Advance Notice of Proposed Rulemaking No. 86-16 (51 FR 39663), 
announcing its tentative intention to amend 14 CFR parts 36 and 91. The 
comment period for Notice No. 86-16 was reopened on March 12, 1987 (52 
FR 7618) to allow interested parties additional time to comment.
    On May 30, 1990, the FAA published Notice of Proposed Rulemaking 
(NPRM) No. 86-16 (55 FR 22020), proposing to amend 14 CFR parts 36 and 
91. These revisions were intended to aid the development of next-
generation supersonic airplanes by establishing a notice standard for 
supersonic airplanes that is consistent with noise limits for 
conventional (subsonic) airplanes. In the NPRM, the FAA requested that 
the public comment on the following issues: (1) Requirement that future 
supersonic airplanes (SST) meet noise limits consistent with those 
required for future subsonic airplanes, (2) recommendations on test and 
measurement conditions and operational characteristics appropriate for 
future SST's, and (3) cost of the proposed rule.
    After analyzing the comments received on the NPRM, the FAA has 
determined that further investigation and research is necessary before 
developing the final rule. The FAA will continue to gather technical 
information and analyze suggested recommendations for test and 
measurement conditions. A statement concerning FAA policy on this 
matter is published elsewhere in this issue of the Federal Register. 
Accordingly, Notice No. 86-16, Docket No. 25109, published in the 
Federal Register on May 30, 1990 (55 FR 22020), is withdrawn.

    Issued in Washington, DC on July 29, 1994.

Acting Director of Environment and Energy.
