Airworthiness Standards; Rotor Overspeed Requirements; Correction

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; correction.

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

SUMMARY: The FAA is correcting an unintentional error in the preamble 
of the final rule, Airworthiness Standards; Rotor Overspeed 
Requirements, published on July 18, 2011 (76 FR 42020). The final rule 
established uniform rotor overspeed design and test requirements for 
aircraft engines and turbochargers certificated by the FAA and the 
European Aviation Safety Agency (EASA). This document corrects an error 
in the preamble.

DATES: Effective September 8, 2011.

SUPPLEMENTARY INFORMATION

Background

    On Monday, July 18, 2011, the FAA published a final rule entitled 
``Airworthiness Standards; Rotor Overspeed Requirements'' (76 FR 
42022). The final rule revised the aircraft turbine engine rotor 
overspeed type certification standards.
    During the review process, we determined a portion of the section 
entitled ``Total Estimated Benefits and Costs of this Proposed Rule'' 
should be removed. We found that this section included a discussion of 
a comment that had already been fully discussed in the paragraph headed 
``Material Properties of Test Rotors''. We are therefore eliminating 
discussion of this comment in the benefits and costs section of the 
preamble.

Correction to Preamble

    1. On page 42022, third column, revise the first full paragraph of 
``Total Estimated Benefits and Costs of This Proposed Rule'' to read as 
follows:

    ``Industry must currently certificate to the two standards that 
are substantively similar, but have a few slightly different testing 
and documentation procedures and requirements. The rule harmonizes 
these procedures and requirements to the higher standard and, 
thereby, may increase safety. In addition, by reducing the amount of 
duplicative testing that would need to be either witnessed or 
analyzed by the FAA, the FAA is better able to prioritize its 
resources to other, more safety critical areas. Consequently, we 
determined that unquantifiable future minimal benefits from the rule 
may also accrue. The FAA concludes that the combination of cost 
savings and potential increased safety benefits will make this rule 
cost beneficial. Further, we therefore determined that this rule is 
not a ``significant regulatory action'' as defined in section 3(f) 
of Executive Order 12866, and is not ``significant'' as defined in 
DOT'S Regulatory Policies and Procedures.''

    This correction ensures correct understanding of and FAA response 
to comments received. There are no changes to the existing regulatory 
text.
