Discussion

On February 25, 2013, at 78 FR 12646, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 to include an AD that would apply to Agusta Model AB412 and AB412 EP, and Bell Model 412, 412CF, and 412EP helicopters with certain Dart crosstubes installed. The NPRM proposed to require establishing a component history card for each crosstube, P/N D412–664–203; revising the airworthiness limitations of the maintenance manual to establish a life limit of 10,000 landings for each crosstube; and removing from service any crosstube with more than 10,000 landings. The proposed requirements were intended to prevent failure of the crosstube and subsequent collapse of the landing gear.

The NPRM was prompted by AD No. CF–2012–14R1, dated May 9, 2012, issued by Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada. TCCA issued AD No. CF–2012–14R1 to correct an unsafe condition for the Dart high gear aft crosstube assembly, part number (P/N) D412–664–203, approved under TCCA Supplemental Type Certificate (STC) SH01–9, FAA STC No. SR01298NY, and European Aviation Safety Agency STC IM.R.S.01304, and installed on Agusta Model AB412 and AB412 EP and Bell Model 412, 412EP, and 412CF helicopters. TCCA advises that they have received five reports of these crosstubes failing. According to TCCA, based on these reports, the affected crosstube requires a life limitation of 10,000 landings. As a result, TCCA issued AD No. CF–2012–14R1, which


### 49114 Federal Register / Vol. 78, No. 156 / Tuesday, August 13, 2013 / Rules and Regulations

requires amending the instructions for continued airworthiness (ICA) to establish the new life limitation, and removing from service all crosstubes with more than 10,000 landings.

Comments

We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (78 FR 12646, February 25, 2013).

FAA’s Determination

These helicopters have been approved by the aviation authority of Canada and are approved for operation in the United States. Pursuant to our bilateral agreement with Canada, TCCA, its technical representative, has notified us of the unsafe condition described in the TCCA AD. We are issuing this AD because we evaluated all information provided by TCCA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed.

Related Service Information

We reviewed Dart ICA No. ICA– D212–664, Revision 8, dated October 20, 2011, which contains the airworthiness limitations, inspection requirements, proper placards and markings, and maintenance procedures for crosstube P/N D212–664 and D412–664. Revision 8 establishes a life limit of 10,000 landings for crosstube P/N D412–664–
203. Costs of Compliance

We estimate that this AD will affect 76 helicopters of U.S. Registry. Based on an average labor cost of $85 per hour, we estimate that operators may incur the following costs in order to comply with this AD. Creating a component history card and amending the ICA requires about 1 work-hour, for a cost per helicopter of $85 and a total cost to U.S. operators of $6,460. Replacing a crosstube that has exceeded its life-limit requires about 6 work-hours and required parts will cost about $10,351, for a total cost per helicopter of $10,861. 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 helicopters 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.

We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket. 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 adding the following new airworthiness directive (AD):

This AD applies to Agusta S.p.A. Model AB412 and AB412 EP helicopters and Bell Helicopter Textron Model 412, 412CF, and 412EP helicopters with a DART AerospaceLtd. high gear aft crosstube (crosstube), partnumber (P/N) D412–664–203 installed under Supplemental Type Certificate (STC) No. SR01298NY, certificated in any category.

**SUPPLEMENTARY INFORMATION :**  AD 2012– 11–02, Amendment 39–17065 (77 FR 37790, June 25, 2012), applies to certain Eurocopter Model EC135 helicopters. AD 2012–11–02 currently requires, in part, visually checking the ring frame which connects the tail rotor Fenestron housing to the tailboom for a crack before further flight and thereafter at each preflight check, and allows this check to be performed by a pilot if certain regulatory recordkeeping requirements are met. As such, AD 2012–11–02 currently includes the following as the last sentence under paragraph (f)(1): ‘‘The record must be maintained as required by 14 CFR 91.173, 121.380, or 134.439.’’

As published, the reference to 14 CFR 91.173 is incorrect. The correct reference is to 14 CFR 91.417.

No other part of the preamble or regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register
