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 full 

and 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, which 

will 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, 

2011. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments.

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2006–24785; Directorate Identifier 

2006–NE–20–AD’’ at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed 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 proposed AD. 

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. 

(5) For engines identified in paragraphs (f), 

(g), (h), or (i) of this AD, owners or operators 

may make an entry in the AD status log 

required by 14 CFR 91.417(a)(2)(v) that this 

AD required no action for compliance. 

(g) If Lycoming Engines manufactured new, 

rebuilt, overhauled, or repaired your engine, 

or replaced the crankshaft in your engine 

before January 1, 1997, and you have not had 

the crankshaft replaced, no further action is 

required. 

(h) If Table 1, Table 2, Table 3, or Table 

4 of Lycoming MSB No. 569A, dated April 

11, 2006, lists your engine serial number 

(S/N), and Table 5 of MSB No. 569A, dated 

April 11, 2006, does not list your crankshaft 

S/N, no further action is required. 

(i) For engine model TIO–540–U2A, S/N 

L–4641–61A, no action is required. 

Engines for Which Action Is Required 

(j) If Table 1, Table 2, Table 3, or Table 4 

of Lycoming MSB No. 569A, dated April 11, 

2006, lists your engine S/N, and Table 5 of 

MSB No. 569A, dated April 11, 2006, lists 

your crankshaft S/N, replace the affected 

crankshaft with a crankshaft that is not listed 

in Table 5 of MSB No. 569A at the earliest 

of the following: 

(1) The time of the next engine overhaul as 

specified in Lycoming Engines Service 

Instruction No. 1009AS, dated May 25, 2006; 

or 

(2) The next separation of the crankcase, or 

(3) No later than 12 years from the time the 

crankshaft first entered service or was last 

overhauled, whichever is later. 

(k) If Table 1, Table 2, Table 3, or Table 

4 of Lycoming MSB No. 569A, dated April 

11, 2006, does not list your engine S/N, and 

Table 5 of MSB No. 569A does list your 

crankshaft S/N (an affected crankshaft was 

installed as a replacement), replace the 

affected crankshaft with a crankshaft that is 

not listed in Table 5 of MSB No. 569A at the 

earliest of the following: 

(1) The time of the next engine overhaul as 

specified in Lycoming Engines Service 

Instruction No. 1009AS, dated May 25, 2006; 

or 

(2) The next separation of the crankcase, or 

(3) No later than 12 years from the time the 

crankshaft first entered service or was last 

overhauled, whichever is later. 

Prohibition Against Installing Certain 

Crankshafts 

(l) After the effective date of this AD, do 

not install any crankshaft that has a S/N 

listed in Table 5 of Lycoming MSB No. 569A, 

dated April 11, 2006, into any engine. 

Alternative Methods of Compliance (AMOC)
