### 40897 Federal Register / Vol. 80, No. 134 / Tuesday, July 14, 2015 / Rules and Regulations

553(a)(2) of the APA, we have determined that notice and public comment are unnecessary and contrary to the public interest. Under 5 U.S.C. 553(b)(A) and (B) of the APA, an agency may publish regulations in final form when they involve matters of agency organization or where the agency for good cause finds that notice and public comment are impracticable, unnecessary, or contrary to the public interest. As discussed above, this amendment results from recent address changes due to the relocation of one field office. Because the amendment will provide accurate and current information on field office addresses to the public, it would be contrary to the public interest to delay amending the regulation. III. Regulatory Flexibility Act

Pursuant to section 605(b) of the Regulatory Flexibility Act (5 U.S.C. 601 et seq. ), FCA hereby certifies that the final rule will not have a significant economic impact on a substantial number of small entities. Each of the banks in the Farm Credit System (System), considered together with its affiliated associations, has assets and annual income in excess of the amounts that would qualify them as small entities. Therefore, System institutions are not ‘‘small entities’’ as defined in the Regulatory Flexibility Act. List of Subjects in 12 CFR Part 600

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to the specified products. The NPRM was published in the Federal Register on April 10, 2015 (80 FR 19244). The NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

It has been identified that misalignment between the quill shaft of the engine and the Power Turbine (PT) shaft may lead to a rupture of the quill shaft.

This condition, if not detected and corrected, could lead to overspeed of the PT and consequent uncontained engine failure, possibly resulting in damage to the aeroplane and injury to occupants and/or persons on the ground.

Related Service Information Under 1 CFR Part 51

We reviewed GE Aviation Czech s.r.o. Alert Service Bulletins (ASBs) No. M601E–11/28, M601E–11A/15, and M601F/26, all Revision 2, all dated January 23, 2015. This service information describes procedures for inspecting the M601 reduction gearbox and supporting cone. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the **ADDRESSES** section of this AD.


### 40898 Federal Register / Vol. 80, No. 134 / Tuesday, July 14, 2015 / Rules and Regulations

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 19244, April 10, 2015).

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed. Costs of Compliance

We estimate that this AD affects 16 engines installed on airplanes of U.S. registry. We also estimate that it would take about 112 hours per engine to comply with this AD. The average labor rate is $85 per hour. Required parts cost about $21,376 per engine. Based on these figures, we estimate the cost of this AD on U.S. operators to be $494,336. Our cost estimate is exclusive of possible warranty coverage. Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ‘‘Subtitle VII: Aviation Programs,’’ describes in more detail the scope of the Agency’s authority.

We are issuing this rulemaking under the authority described in ‘‘Subtitle VII, Part A, Subpart III, Section 44701: General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this AD:

(1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866,

(2) Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and

(4) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

**PART 39—AIRWORTHINESS DIRECTIVES**

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. The NPRM published in the Federal Register on June 11, 2014 (79 FR 33484). The NPRM was prompted by reports of fatigue cracks found in the upper corners of the forward entry door skin cutout. The NPRM proposed to require repetitive inspections for cracking in the upper corners of the forward entry door skin cutout, and repair if necessary. Accomplishment of this repair or a preventive modification would terminate the repetitive inspections. We are issuing this AD to detect and correct cracking in the doorway upper corners, which could result in cabin depressurization.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (79 FR 33484, June 11, 2014) and the FAA’s response to each comment. Support for the NPRM (79 FR 33484, June 11, 2014)

Boeing stated that it supports the NPRM (79 FR 33484, June 11, 2014). Request To Clarify Terminating Action

Southwest Airlines (SWA) requested confirmation that paragraph 3.B.4. of the Accomplishment Instructions of Boeing Alert Service Bulletin 737–53A1163, Revision 1, dated January 8, 2014, is an acceptable terminating action for the inspection requirements of paragraph (g)(1) of this NPRM (79 FR 33484, June 11, 2014) for the repaired door corners.

SWA stated that the repairs provided in Part 3 of the Accomplishment
