### 6669 Federal Register / Vol. 77, No. 27 / Thursday, February 9, 2012 / Rules and Regulations

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); and

3. 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 a regulatory 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 AD:
2012–02–04 Rolls-Royce plc: Amendment 39–16927; Docket No. FAA–2012–0004; Directorate Identifier 2012–NE–01–AD. (a) Effective Date This airworthiness directive (AD) becomes effective February 24, 2012.
(b) Affected ADs

None. (c) Applicability

This AD applies to Rolls-Royce plc RB211– Trent 553–61, RB211–Trent 553A2–61, RB211–Trent 556–61, RB211–Trent 556A2– 61, RB211–Trent 556B–61, RB211–Trent 556B2–61, RB211–Trent 560–61, and RB211– Trent 560A2–61 turbofan engines that have not complied with Rolls-Royce plc Service Bulletin No. RB.211–73–G723, and that have any of the following fuel tube part numbers installed:

(1) FW57605. (2) FW17689. (3) FW57604. (4) FK30710. (5) FW57578. (6) FK30713.
(d) Reason

This AD was prompted by reports of wear found between the securing clips and the low-pressure (LP) fuel tube outer surface, which reduces the fuel tube wall thickness, leading to fracture of the fuel tube and consequent fuel leak. We are issuing this AD to prevent engine fuel leaks, which could result in risk to the airplane.
(e) Actions and Compliance

Unless already done, do the following onetime actions within 1,600 flight hours after the effective date of this AD.

(1) Visually inspect the fuel tube clips holding the LP fuel tube run from the LP fuel pump to the fuel-oil-heat exchanger, and the clips holding the LP fuel tube run from the LP filter to the high-pressure (HP) fuel pump, for evidence of damage or wear and replace as necessary. Do this in accordance with paragraphs 3.A(4)(a) through 3.A(4)(c) of Rolls-Royce plc Alert Service Bulletin No. RB.211–73–AG797, dated October 26, 2011.

(2) Clean and dry the LP fuel tube run from the LP fuel pump to the fuel-oil-heat exchanger, and the LP fuel tube run from the LP filter to the HP fuel pump.

(i) Visually inspect for evidence of damage, wear near the clip locations, and for fuel leakage.

(ii) Reject the tube and replace it if evidence of fuel leakage or contact frettage to a depth of greater than 0.1 mm (0.004 in.) on the outer surface of a bend, or 0.2 mm (0.008 in.) in any other area, is evident.
(f) Alternative Methods of Compliance (AMOCs)

The Manager, Engine Certification Office, may approve AMOCs for this AD. Use the procedures found in 14 CFR 39.19 to make your request. (g) Related Information

(1) For more information about this AD, contact Alan Strom, Aerospace Engineer, Engine Certification Office, FAA, Engine & Propeller Directorate, 12 New England Executive Park, Burlington, MA 01803; email: alan.strom@faa.gov; phone: (781) 238– 7143; fax: (781) 238–7199.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on August 9, 2011 (76 FR 48749). That NPRM proposed to require inspecting certain S/N first stage turbine disks, P/N 3101520–1 and P/N
3107079–1.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM. Conclusion

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

We estimate that this AD affects 90 engines installed on airplanes of U.S. registry. We also estimate that it will take about 20 work-hours per engine to perform these actions, and that the average labor rate is $85 per work-hour. Required parts cost about $19,000 per engine. We estimate that one disk will fail the initial inspection and that repetitive inspections will be performed on 89 engines. We estimate that one engine will fail the repetitive inspections and that further repetitive inspections will be performed on 88 engines. We estimate that an additional one disk will fail those repetitive inspections before retirement. Based on these figures, we estimate the total cost of the AD to U.S. operators to be $511,155. 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, 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

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

**ACTION :**  Final rule; request for
comments.

**SUMMARY :**  We are superseding an existing airworthiness directive (AD) for Superior Air Parts and Lycoming Engines fuel-injected reciprocating engines. That AD currently requires removing AVStar Fuel Systems, Inc. (AFS) fuel servos installed after May 20, 2010, if the servo contained an AFS diaphragm, part number (P/N) AV2541801 or P/N AV2541803, from certain production lots. This AD expands the applicability, and changes the compliance interval for all affected Superior Air Parts, Lycoming Engines,and Continental Motors, Inc., fuelinjected reciprocating engines. This AD was prompted by an accident involving a Piper PA32R–301 airplane, and by the discovery of additional engines being affected by the unsafe condition since we issued the existing AD. We are issuing this AD to prevent an in-flight engine shutdown due to a failed fuel servo diaphragm, and damage to the airplane.

**DATES :**  This AD is effective February 24,
2012.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of August 16, 2011 (76 FR 45655, August 1, 2011).

We must receive any comments on this AD by March 26, 2012.
