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 §§ 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 

§§ 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 

§§ 27.573 and 29.573. 

Issued in Washington, DC, on August 13, 

2012.

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 § 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 

§ 29.571 publication. 

Under the Paperwork Reduction Act, 

the FAA submitted the new information 

collection requirements for OMB 

review. OMB approved the collection on
