DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 23

 
Damage Tolerance and Fatigue Evaluation of Structure

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; technical amendment.

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

SUMMARY: This action corrects a paragraph reference that appeared in 
the final rule, Airworthiness Standards; Airframe Rules Based on 
European Joint Aviation Requirements, which the FAA published in the 
Federal Register on February 9, 1996. In that final rule, the FAA 
inadvertently changed a paragraph reference. The intent of this action 
is to correct the error in the regulation to ensure the requirement is 
clear and accurate.

DATES: Effective Date: April 11, 2008.

FOR FURTHER INFORMATION CONTACT: Pat Mullen, Regulations and Policy, 
ACE-111, Federal Aviation Administration, 901 Locust Street, Kansas 
City, MO 64106; telephone (816) 329-4111; e-mail pat.mullen@faa.gov.

SUPPLEMENTARY INFORMATION: On February 9, 1996, the FAA published in 
the Federal Register (61 FR 5147) a final rule that amended Sec.  
23.573(b) by removing the reference ``Sec.  23.571(c)'' and adding the 
reference ``Sec.  23.571(a)(3)'' in its place. Paragraph (a)(3) of 
Sec.  23.571 does not exist, and the reference to Sec.  23.571(c) 
should have remained. This document corrects Sec.  23.573(b) to reflect 
the correct paragraph reference, Sec.  23.571(c). This correction will 
not impose any additional requirements.

Technical Amendment

    This technical amendment will correct Sec.  23.573(b) to properly 
reference Sec.  23.571(c).

Justification for Immediate Adoption

    Because this action corrects an incorrect paragraph reference, the 
FAA finds that notice and public comment under 5 U.S.C. 553(b) is 
unnecessary. For the same reason, the FAA finds that good cause exists 
under 5 U.S.C. 553(d) for making this rule effective upon publication.
