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

**SUMMARY :**  We are superseding an existing airworthiness directive (AD) for RR RB211–Trent 700 series turbofan engines. That AD currently requires, for the step aside gearbox (SAGB), repositioning of the oil metering jet up into the oil distributor within the bevel gearshaft, followed by initial and repetitive visual inspections of the magnetic chip detector (MCD). Since we issued that AD, RR has demonstrated that the repositioning of the oil metering jet eliminates the need for the repetitive inspections. This AD changes the applicability from RB211–Trent 700 series turbofan engines, to RB211–Trent 768–60 and Trent 772–60 turbofan engines. This AD also eliminates the visual inspections of the MCD from the AD requirements. This AD was prompted by RR demonstrating that the repositioning of the oil metering jet eliminates the need for the repetitive inspections, by the need to correct the AD applicability, and by the need to eliminate the visual inspections of the MCD. We are issuing this AD to prevent in-flight engine shutdowns caused by SAGB driving bevel gearshaft ball bearing failure.

**DATES :**  This AD is effective April 27,
2011.

The Director of the Federal Register previously approved the incorporation by reference of a certain publication listed in this AD as of October 1, 1998 (63 FR 49416, September 16, 1998).

We must receive any comments on this AD by May 27, 2011.

**SUPPLEMENTARY INFORMATION :** 

Discussion

On September 8, 1998, we issued AD 98–19–12, Amendment 39–10754 (63 FR 49416, September 16, 1998), for RR RB211–Trent 700 series turbofan engines. That AD requires, for the SAGB, repositioning of the oil metering jet up into the oil distributor within the bevel gearshaft, followed by initial and repetitive visual inspections of the MCD. That AD resulted from reports of uncommanded engine shutdowns caused by failure of the SAGB driving bevel gearshaft ball bearing due to oil starvation. We issued that AD to prevent in-flight engine shutdowns caused by SAGB driving bevel gearshaft ball bearing failure.

Actions Since AD Was Issued

Since we issued AD 98–19–12, RR has demonstrated that the repositioning of the oil metering jet eliminates the need for the repetitive inspections. Also, since we issued that AD, Rolls Royce put into service, its RB211–Trent 772B–


### 20230 Federal Register / Vol. 76, No. 70 / Tuesday, April 12, 2011 / Rules and Regulations

60 model turbofan engine, which does not have the unsafe condition that AD sought to correct. Since the AD applicability states that it is for RB211– Trent 700 series turbofan engines, that applicability includes the RB211–Trent 772B–60 engines, and it shouldn’t.

FAA’s Determination

We are issuing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.
AD Requirements

This AD retains the oil metering jet repositioning requirements of AD 98–19–12. This AD also eliminates the initial and repetitive visual inspections of the MCD, required by AD 98–19–12. This AD also corrects the applicability from RB211–Trent 700 series turbofan engines, to, RB211–Trent 768–60 turbofan engines prior to serial No. 41052, and RB211–Trent 772–60 turbofan engines prior to serial No.
41052. FAA’s Justification and Determination of the Effective Date

Since no domestic operators use RB211–Trent 768–60 or RB211–Trent 772–60 turbofan engines, we find that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the **ADDRESSES** section. Include the docket number FAA–2011–0233 and Directorate Identifier 98–ANE–10–AD at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those
comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance

We estimate that this AD affects no engines installed on airplanes of U.S. registry. The elimination of visual inspection requirements by this AD, adds no additional economic burden. 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

**SUPPLEMENTARY INFORMATION :** 

Discussion

We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That SNPRM published in the Federal Register on December 17, 2010 (75 FR 78937). The original notice of proposed rulemaking (74 FR 67829, December 21, 2009) proposed to require removing power turbine blades, part number (P/N) 4–141–084–06 from service, using a drawdown schedule. The SNPRM proposed to require expanding and clarifying the applicability to include more engine models and power turbine blade P/Ns that could have the unsafe condition, and clarifying the applicability by specifying power turbine rotor P/Ns instead of the blade P/Ns.

Comments

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

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 will affect 240 engines installed on aircraft of U.S. registry. We also estimate that it will take about 30 work-hours per engine to perform the actions, and that the average labor rate is $85 per work-hour. If all removed power turbine rotors get replaced, required parts will cost about $70,000 per engine. Based on these figures, we estimate the total cost of the AD to U.S. operators to be $17,412,000. 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),
