Fatigue Tolerance Evaluation of Metallic Structures; OMB Approval 
of Information Collection

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; OMB approval of information collection.

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

SUMMARY: This document notifies the public of the Office of Management 
and Budget's (OMB's) approval of the information collection requirement 
contained in the FAA's final rule, ``Fatigue Tolerance Evaluation of 
Metallic Structures,'' which was published on December 2, 2011.

DATES: The rule published on December 2, 2011, and became effective on 
January 31, 2012. However, at the time of publication, the new 
information collection requirements imposed by 14 CFR 29.571, lacked 
OMB approval. This document announces receipt of OMB's June 28, 2012 
approval.

SUPPLEMENTARY INFORMATION: The final rule, ``Fatigue Tolerance 
Evaluation of Metallic Structures,'' published in the Federal Register 
(76 FR 75435) on December 2, 2011. In that rule, the FAA addresses 
advances in structural fatigue substantiation technology for metallic 
structures that provides an increased level of safety by avoiding or 
reducing the likelihood of the catastrophic fatigue failure of a 
metallic structure. These increased safety requirements help ensure 
that should serious accidental damage occur during manufacturing or 
within the operational life of the rotorcraft, the remaining structure 
could withstand, without failure, any fatigue loads that are likely to 
occur, until the damage is detected or the part is replaced.
    In a correction document (77 FR 4890), published February 1, 2012, 
the FAA revised the DATES section of the final rule, noting that 
affected parties were not required to comply with the new information 
collection requirements in Sec.  29.571 until OMB approved the FAA's 
request to collect the information. Section 29.571 includes new 
provisions requiring an applicant, when trying to obtain type 
certification of a rotorcraft, to submit substantiating data to show 
that the rotorcraft complies with specific certification requirements. 
OMB's approval for the information collection requirement was pending 
at the time of Sec.  29.571 publication.
    Under the Paperwork Reduction Act, the FAA submitted the new 
information collection requirements for OMB review. OMB approved the 
collection on

June 28, 2012, and assigned the information collection OMB Control 
Number 2120-0752, which expires on June 30, 2015.
    This publication informs affected parties of the approval and 
announces that as of June 28, 2012, affected parties are required to 
comply with the new information collection requirements in Sec.  
29.571.

    Issued in Washington, DC, on August 13, 2012.

Acting Director, Office of Rulemaking.
