**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule. **SUMMARY :**  We are superseding Airworthiness Directive (AD) 2009–05– 09 for Bell Model 412, 412CF, and 412EP helicopters. AD 2009–05–09 required reidentifying each affected part-numbered main rotor yoke (yoke) on its data plate, reducing the retirement life of the reidentified yoke, and revising the Airworthiness Limitations section of the maintenance manual or the Instructions for Continued Airworthiness (ICAs) accordingly. This new AD retains the requirements of AD 2009–05–09 with the exception of the P/N marking location. This AD was prompted by fatigue analysis that shows the retirement life should be reduced on certain yokes. We are issuing this AD to correct the unsafe condition on these helicopters.

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2009–05–09, Amendment 39–15833 (74 FR 11001, March 16, 2009). AD 2009–05–09 applied to Bell Model 412, 412CF, and


### 63859 Federal Register / Vol. 78, No. 207 / Friday, October 25, 2013 / Rules and Regulations

412EP helicopters. The NPRM published in the Federal Register on June 11, 2013 (78 FR 34958). The NPRM proposed to retain the requirements of AD 2009–05–09 to reidentify each affected part-numbered yoke based on whether it was ever installed on a Model 412CF helicopter or on a Model 412 or 412EP helicopter with a slope landing kit, reduce the retirement life of each reidentified yoke, revise the Airworthiness Limitations section of the maintenance manual or ICAs accordingly, and record each reidentified yoke P/N and the reduced retirement life on the component history card or equivalent record. However, the NPRM proposed to change the requirement to reidentify the yoke by etching the new P/N on the side of the yoke instead of on the data plate.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 34958, June 11, 2013) or on the determination of the cost to the public.

FAA’s Determination

We have reviewed the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed except for minor editorial changes in paragraphs (f)(2) and (f)(3) to clarify the intent of paragraph (f)(2) and to remove an unnecessary reference. These minor editorial changes are consistent with the intent of the proposals in the NPRM (78 FR 34958, June 11, 2013) and will not increase the economic burden on any operator nor increase the scope of the AD. Costs of Compliance

We estimate that this AD will affect 115 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. It will take about 3 work hours to review and revise the records to reflect the new retirement life and reidentify the P/N at an average labor rate of $85 per work hour. Based on these estimates, the cost will be $255 per helicopter and $29,325 for the U.S. operator fleet. Replacing a yoke will take about 20 work hours and $50,196 for the required parts for a cost of $51,896 per helicopter. 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

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 that this AD:

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

(2) Is not a ‘‘significant rule’’ under 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** 

■ 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2009–05–09, Amendment 39–15833 (74 FR 11001, March 16, 2009), and adding the following new AD:
2013–20–18 Bell Helicopter Textron, Inc.: Amendment 39–17624; Docket No. FAA–2013–0500; Directorate Identifier 2012–SW–45–AD.
(a) Applicability

This AD applies to Model 412 and 412EP helicopters with a main rotor yoke assembly (yoke), part number (P/N) 412–010–101–123, –127, –129, or –133, installed; and Model 412CF helicopters with a yoke, P/N 412–010– 101–127 or –129, installed; certificated in any category.
(b) Unsafe Condition

This AD defines the unsafe condition as fatigue cracking of a yoke, failure of the yoke, and subsequent loss of control of the helicopter.

(c) Affected ADs

This AD supersedes AD 2009–05–09, Amendment 39–15833 (74 FR 11001, March 16, 2009).

(d) Effective Date

This AD becomes effective November 29,
2013. (e) Compliance

You are responsible for performing each action required by this AD within the specified compliance time, unless it has been accomplished previously.
(f) Required Actions

Within 10 hours time-in-service (TIS): (1) Review the helicopter records to determine all of the helicopter models on which an affected yoke has been installed since its production and the hours TIS of each affected yoke.

(2) If an affected part-numbered yoke has ever been installed on a Model 412CF helicopter or on a Model 412 or 412EP helicopter with a slope landing kit, P/N 412– 704–012–101, installed, do the following:

(i) Reidentify the P/N on the side of the yoke by using a vibrating stylus and etching two lines through the last three digits of the existing P/N and etching ‘‘137FM’’ adjacent to where you etched through the last three digits of the original P/N. This converts each affected yoke P/N to a new yoke P/N 412– 010–101–137FM. The serial number remains the same.

Note 1 to paragraph (f)(2)(i) of this AD:The ‘‘FM’’ P/N suffix denotes a fieldmodified part.

(ii) Treat the etched surface with chemical film, and apply primer and paint.

(iii) Record the reidentified P/N on the applicable component history card or equivalent record.

(3) If you cannot determine all the model helicopters on which an affected yoke has been installed since its production or whether it has ever been installed on a Model 412 or 412EP helicopter with a slope landing kit, P/N 412–704–012–101, installed, perform the actions required by paragraphs (f)(2)(i) through (f)(2)(iii) of this AD.

(4) For each reidentified yoke, P/N 412– 010–101–137FM, reduce the retirement life


### 63860 Federal Register / Vol. 78, No. 207 / Friday, October 25, 2013 / Rules and Regulations

from 5,000 hours TIS to 4,500 hours TIS. Record the revised life limit on the applicable component history card or equivalent record.

(5) Revise the Airworthiness Limitations section of the applicable maintenance manual or the Instructions for Continued Airworthiness by reducing the retirement life from 5,000 hours TIS to 4,500 hours TIS for each reidentified yoke, P/N 412–010–101–
137FM.
(g) Special Flight Permit

Special flight permits will not be issued.

**14 CFR Part 71**

**[Docket No. FAA–2013–0817; Airspace Docket No. 13–AWP–14]** 

**RIN 2120–AA66**

**Amendment of Class D Airspace; Kwajalein Island, Marshall Islands, RMI** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Final rule, technical amendment.

**SUMMARY :**  This action amends the Kwajalein Island Class D airspace description by amending the geographic coordinates for Bucholz Army Airfield (AAF), Kwajalein Island, Marshall Islands, RMI. The Bucholz AAF geographic coordinates information was updated in the Kwajalein Island Class E airspace descriptions in 2011, but was inadvertently overlooked in the Kwajalein Island Class D airspace description. This action ensures the safety of aircraft operating in the Kwajalein Island airspace area. This is an administrative action and does not affect the operating requirements of the airspace.

**DATES :**  Effective date 0901 UTC, December 12, 2013. The Director of the Federal Register approves this incorporation by reference action under 1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and publication of conforming amendments.

**FOR FURTHER INFORMATION CONTACT :**  Colby Abbott, Airspace Policy and ATC Procedures Group, Office of Airspace Services, Federal Aviation Administration, 800 Independence Avenue SW., Washington, DC 20591; telephone: (202) 267–8783.

**SUPPLEMENTARY INFORMATION :**  History

In 2010, the FAA published a final rule, technical amendment in the Federal Register (75 FR 61993, October 7, 2010) that removed reference to the decommissioned Kwajalein Tactical Air Navigation (TACAN) navigation aid from the Kwajalein Island Class E airspace area legal descriptions. Subsequent to that rule being published, it was determined that the Bucholz AAF geographic coordinates were in error. As a result, the FAA published a final rule, correction in the Federal Register (76 FR 2572, January 14, 2011) to correcting the Bucholz AAF geographic coordinates information in the Kwajalein Island Class E airspace descriptions and to match the FAA’s aeronautical database. Unfortunately, consideration for correcting the Bucholz AAF geographic coordinates in the Kwajalein Island Class D airspace description was overlooked at that time and is now being corrected.

The Rule

This action amends Title 14 Code of Federal Regulations (CFR) part 71 by amending the geographic coordinates for Bucholz AAF in the Kwajalein Island, Marshall Islands, RMI, Class D airspace legal description to reflect current FAA aeronautical database information. The geographic coordinates for Bucholz AAF, are changed from (lat.
08 ° 43 ′00 ′′ N., long. 167 ° 44 ′00 ′′ E) to (lat.
08 ° 43 ′ 12 ′′ N., long. 167 ° 43 ′ 54 ′′ E.) This action more accurately depicts the center of the Kwajalein Island Class D airspace area with no other changes to the dimensions or altitudes of the Class D airspace area. Therefore, notice and public procedures under 5 U.S.C. 553(b)
are unnecessary.

Class D airspace areas are published in paragraph 5000 of FAA Order 7400.9X dated August 7, 2013, and effective September 15, 2013, which is incorporated by reference in 14 CFR 71.1. The Class D airspace area listed in this action will be published subsequently in the Order.

The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. Therefore, this regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under Department of Transportation (DOT) Regulatory Policies and Procedures (44 FR 11034; February 26, 1979); and (3) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. Since this is a routine matter that only affects air traffic procedures and air navigation, it is certified that this rule, when promulgated, does not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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.

This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is
