Damage Tolerance and Fatigue Evaluation of Composite Rotorcraft 
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, ``Damage Tolerance and Fatigue 
Evaluation of Composite Rotorcraft Structures,'' which was published on 
December 1, 2011.

DATES: The rule published on December 1, 2011, and became effective on 
January 30, 2012. However, at the time of publication, the new 
information collection requirements imposed by 14 CFR 27.573 and 29.573 
lacked OMB approval. This document announces receipt of OMB's June 28, 
2012 approval.

SUPPLEMENTARY INFORMATION: The final rule, ``Damage Tolerance and 
Fatigue Evaluation of Composite Rotorcraft Structures,'' published in 
the Federal Register (76 FR 74655) on December 1, 2011. In that rule, 
the FAA amended its regulations to require evaluation of fatigue and 
residual static strength of composite rotorcraft structures using a 
damage tolerance evaluation, or a fatigue evaluation if the applicant 
establishes that a damage tolerance evaluation is impractical.
    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. Sec.  27.573 and 29.573 until OMB 
approved the FAA's request to collect the information. Sections 27.573 
and 29.573 include new provisions requiring an applicant to submit 
damage tolerance and fatigue evaluation information for principal 
composite structural elements or components, detail design points, and 
fabrication techniques. OMB approval for the information collection 
requirement was pending at the time of Sec. Sec.  27.573 and 29.573 
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 2120-0753, which expires on December 31, 2012.
    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. Sec.  
27.573 and 29.573.

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

Acting Director, Office of Rulemaking.
