bargaining table in an attempt to reach a consensus, as opposed to keeping key issues in reserve. The second is a willingness to keep the issues at the table and not take them to other forums. Finally, good faith includes a willingness to move away from some of the positions often taken in a more traditional rulemaking process, and instead explore openly with other parties all ideas that may emerge from the subcommittee’s discussions.

E. Facilitator

The facilitator will act as a neutral in the substantive development of the proposed standard. Rather, the facilitator’s role generally includes:

• Impartially assisting the members of the subcommittee in conducting discussions and negotiations;

• Impartially assisting in performing the duties of the Designated Federal Official under FACA; and
F. Department Representative

The DOE representative will be a fulland active participant in the consensusbuilding negotiations. The Department’s representative will meet regularly with senior Department officials, briefing them on the negotiations and receiving their suggestions and advice so that he or she can effectively represent the Department’s views regarding the issues before the subcommittee. DOE’s representative also will ensure that the entire spectrum of governmental interests affected by the standards rulemaking, including the Office of Management and Budget, the Attorney General, and other Departmental offices, are kept informed of the negotiations and encouraged to make their concerns known in a timely fashion.

G. Subcommittee and Schedule

After evaluating the comments submitted in response to this notice and the requests for nominations, DOE will either inform the members of the subcommittee that they have been selected or determine that conducting a negotiated rulemaking is inappropriate. Due to the court-ordered deadline, DOE plans for the subcommittee to conduct deliberations in the summer and fall of 2011 and hopes that the subcommittee will come to an agreement on a Notice of Proposed Rulemaking in time to publish that proposal by the October 1, 2011 date contained in the settlement agreement described above.

DOE will advise subcommittee members of administrative matters related to the functions of the subcommittee before beginning. DOE will establish a meeting schedule based on the settlement agreement and produce the necessary documents so as to adhere to that schedule. While the negotiated rulemaking process is underway, DOE is committed to performing much of the same analysis as it would during a normal standards rulemaking process and to providing information and technical support to the subcommittee. IV. Comments Requested

DOE requests comments on whether it should use negotiated rulemaking for its rulemaking pertaining to the energy efficiency of distribution transformers and the extent to which the issues, parties, and procedures described above are adequate and appropriate. DOE also requests comments on which parties should be included in a negotiated rulemaking to develop draft language pertaining to the energy efficiency of distribution transformers and suggestions of additional interests and/ or stakeholders that should be represented on the subcommittee. All who wish to participate as members of the subcommittee should submit a request for nomination to DOE. V. Approval of the Office of the Secretary

The Secretary of Energy has approved publication of today’s notice of intent to establish a subcommittee and negotiate a proposed rule.

Issued in Washington, DC, on August 5,
2011. Kathleen Hogan, Deputy Assistant Secretary, Energy Efficiency and Renewable Energy.

**AGENCY**

### : Federal Aviation Administration (FAA), DOT.

**ACTION** 

### : Notice of proposed rulemaking (NPRM).

**SUMMARY**

### : We propose to supersede an existing airworthiness directive (AD) that applies to the products listed above. The existing AD currently requires replacing certain crankshafts. Since we issued that AD, Lycoming Engines discovered that the start date of affected engine models in Mandatory Service Bulletin (MSB) No. 569A, is incorrect. This proposed AD would correct that start date. We are proposing this AD to prevent failure of the crankshaft, whichwill result in total engine power loss, inflight engine failure, and possible loss of the aircraft.

**DATES**

### : We must receive comments on this proposed AD by September 26,

Discussion

On September 20, 2006, we issued AD 2006–20–09, Amendment 39–14778 (71 FR 57407, September 29, 2006), for Lycoming Engines (L)O–360, (L)IO–360, AEIO–360, O–540, IO–540, AEIO–540, (L)TIO–540, IO–580, and IO–720 series reciprocating engines. That AD requires replacing certain crankshafts. That AD resulted from reports of 23 confirmed failures of similar crankshafts in Lycoming Engines 360 and 540 series reciprocating engines. We issued that AD to prevent failure of the crankshaft, which will result in total engine power loss, in-flight engine failure, and possible loss of the aircraft. Actions Since Existing AD was Issued

Since we issued AD 2006–20–09, Lycoming Engines discovered that the March 1, 1997 start date of affected engine models in Mandatory Service Bulletin (MSB) No. 569A, is incorrect.

Relevant Service Information

We reviewed Lycoming Engines MSB No. 569A, dated April 11, 2006. That MSB describes procedures for replacing crankshafts listed by serial number in that MSB. We also reviewed Lycoming Engines Supplement No. 1 to MSB 569A, dated May 27, 2009. The supplement corrects the start date of affected engine models, to January 1,
1997.

FAA’s Determination

We are proposing 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 these same type designs. Proposed AD Requirements

This proposed AD would retain all of the requirements of AD 2006–20–09. This proposed AD would change the start date of affected engine models, from March 1, 1997, to January 1, 1997. Costs of Compliance

We estimate that this proposed AD would require no additional costs of compliance over those in the original AD, AD 2006–20–09, which are $60,384,000. This proposed AD carries over the original costs of compliance. We estimate that this proposed AD would affect 3,774 engines installed on airplanes of U.S. registry. Because the proposed AD compliance interval coincides with engine overhaul or other engine maintenance, we estimate no additional labor hours will be needed to comply with this proposed AD. Parts would cost about $16,000 per engine. Based on these figures, we estimate the total cost of the proposed AD to be $60,384,000. Our estimate is independent of any 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 have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation:

(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, 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. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 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) 2006–20–09, Amendment 39–14778 (71 FR 57407, September 29, 2006), and adding the following new AD:
Lycoming Engines (formerly Textron Lycoming): Docket No. FAA–2006– 24785; Directorate Identifier 2006–NE– 20–AD.

Comments Due Date

(a) The FAA must receive comments on this AD action by September 26, 2011.

Affected ADs

(b) This AD supersedes AD 2006–20–09, Amendment 39–14778.
Applicability

(c) This AD applies to those Lycoming Engines (L)O–360, (L)IO–360, AEIO–360, O– 540, IO–540, AEIO–540, (L)TIO–540, IO–580, and IO–720 series reciprocating engines listed by engine model number and serial number in Table 1, Table 2, Table 3, or Table 4 of Lycoming Mandatory Service Bulletin (MSB) 569A, dated April 11, 2006, and those engines with crankshafts listed by crankshaft serial number in Table 5 of Lycoming MSB 569A, dated April 11, 2006. These applicable engines are manufactured new or rebuilt, overhauled, or had a crankshaft installed after January 1, 1997. These engines are installed on, but not limited to, the following aircraft:

Unsafe Condition

(d) This AD results from Lycoming Engines discovering that the March 1, 1997 start date of affected engine models in Mandatory Service Bulletin (MSB) No. 569A, is incorrect. Lycoming Engines issued Supplement 1 to MSB No. 569A, dated May 27, 2009, which corrected the date of affected engine models, to January 1, 1997. We are issuing this AD to prevent failure of the crankshaft, which will result in total engine power loss, in-flight engine failure, and possible loss of the aircraft.
Compliance

(e) You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
Engines for Which No Action Is Required

(f) If your engine meets any of the following conditions, and you have not had the crankshaft replaced since meeting the condition, no further action is required:

(1) Engines that are in compliance with Lycoming MSB No. 552 (AD 2002–19–03) or MSB No. 553 (AD 2002–19–03 Table 3 or Table 5); or

(2) Engines that are in compliance with Lycoming MSB No. 566 AD (2005–19–11); or

(3) Engines that are in compliance with Lycoming Supplement No. 1 to MSB No. 566 (AD 2006–06–16); or

(4) Engines that are in compliance with the original issue of Lycoming MSB No. 569, MSB No. 569A, and Supplement 1 to MSB No. 569A.
