Download as PDF 37682 Federal Register / Vol. 76, No. 124 / Tuesday, June 28, 2011 / Proposed Rules action for purposes of E.O. 12866, and the OIRA Administrator has not designated this proposed determination as a significant energy action under E.O. 12866 or any successor order. Therefore, this proposed determination is not a significant energy action. Accordingly, DOE has not prepared a Statement of Energy Effects for this proposed determination. L. Review Under the Information Quality Bulletin for Peer Review On December 16, 2004, OMB, in consultation with the Office of Science and Technology Policy (OSTP), issued its Final Information Quality Bulletin for Peer Review (the Bulletin). 70 FR 2664 (January 14, 2005). The Bulletin establishes that certain scientific information shall be peer reviewed by qualified specialists before it is disseminated by the Federal government, including influential scientific information related to agency regulatory actions. The purpose of the Bulletin is to enhance the quality and credibility of the Government’s scientific information. DOE has determined that the analyses conducted for this rulemaking do not constitute ‘‘influential scientific information,’’ which the Bulletin defines as ‘‘scientific information the agency reasonably can determine will have or does have a clear and substantial impact on important public policies or private sector decisions.’’ 70 FR 2667 (January 14, 2005). The analyses were subject to predissemination review prior to issuance of this rulemaking. DOE will determine the appropriate level of review that would be applicable to any future rulemaking to establish energy conservation standards for fans, blowers and fume hoods. VI. Public Participation emcdonald on DSK2BSOYB1PROD with PROPOSALS A. Submission of Comments DOE will accept comments, data, and information regarding this notice of proposed determination no later than the date provided at the beginning of this notice. After the close of the comment period, DOE will review the comments received and determine whether fans, blowers, fume hoods is covered equipment under EPCA. Comments, data, and information submitted to DOE’s e-mail address for this proposed determination should be provided in WordPerfect, Microsoft Word, PDF, or text (ASCII) file format. Submissions should avoid the use of special characters or any form of encryption, and wherever possible comments should include the electronic VerDate Mar<15>2010 16:26 Jun 27, 2011 Jkt 223001 signature of the author.

If DOE determines that fans, blowers, and fume hoods qualify as covered equipment, DOE will consider a test procedure and energy conservation standards for fans, blowers, and fume hoods. Members of the public will be given an opportunity to submit written and oral comments on any proposed test procedure and standards. Issued in Washington, DC, on June 21, 2011. Kathleen B. Hogan, Deputy Assistant Secretary, Energy Efficiency and Renewable Energy. [FR Doc. 2011–16134 Filed 6–27–11; 8:45 am] BILLING CODE 6450–01–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2011–0085; Directorate Identifier 2000–NE–19–AD] RIN 2120–AA64 Airworthiness Directives; Teledyne Continental Motors (TCM) and RollsRoyce Motors Ltd. (R–RM) Series Reciprocating Engines Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to certain TCM and R–RM series reciprocating engines. The existing AD currently requires replacement of certain magnetos if they fall within the specified serial number (S/N) range, inspection of the removed magneto to verify that the stop pin is still in place, and, if the stop pin is not in place, inspection of the engine gear train, crankcase, and accessory case. Since we issued that AD, we became aware of an error in the previous AD applicability in the range of magneto S/Ns affected, and of the need to include certain engines made by R–RM, under license of TCM. This proposed AD would correct the range of S/Ns affected, require the same replacement and inspections, and would add R–RM C–125, C–145, O–300, IO–360, TSIO– 360, and LTSIO–520–AE series reciprocating engines to the applicability. We are proposing this AD to correct the unsafe condition on these products. DATES: We must receive comments on this proposed AD by August 12, 2011.

SUPPLEMENTARY INFORMATION: emcdonald on DSK2BSOYB1PROD with PROPOSALS 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–2011–0085; Directorate Identifier 2000–NE–19–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 VerDate Mar<15>2010 16:26 Jun 27, 2011 Jkt 223001 closing date and may amend this proposed AD because of those comments. We will post all comments we receive, without change, to https:// 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 June 17, 2002, we issued AD 2002–13–04, Amendment 39–12792 (FR 67 43230, June 27, 2002), for TCM C– 125, C–145, O–300, IO–360, TSIO–360, and LTSIO–520–AE series reciprocating engines. That AD requires, within 10 flight hours after the effective date of that AD, replacement of certain magnetos if they fall within the specified S/N range, inspection of the removed magneto to verify that the stop pin is still in place, and, if the stop pin is not in place, inspection of the engine gear train, crankcase, and accessory case. That AD resulted from reports of engine failures on certain TCM reciprocating engines. We issued that AD to prevent engine failure and loss of control of the airplane due to migration of the magneto impulse coupling stop pin out of the magneto frame and into the gear train of the engine. Actions Since Existing AD Was Issued Since we issued AD 2002–13–04, we became aware of an error in the applicability paragraph of that AD, in the range of S/Ns affected. That AD applicability listed magneto S/Ns of 99110001 through 9912999 inclusive. This proposed AD supersedure would correct the applicability to state magneto S/Ns of 99110001 through 99129999 inclusive, and add R–RM C– 125, C–145, O–300, IO–360, TSIO–360, and LTSIO–520–AE series reciprocating engines built under license of TCM, to the applicability. 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 the same type design. Proposed AD Requirements This proposed AD would retain all requirements of AD 2002–13–04. This proposed AD would also correct the range of S/Ns affected, and would add R–RM C–125, C–145, O–300, IO–360, TSIO–360, and LTSIO–520–AE series reciprocating engines to the applicability. Since AD 2002–13–04 was issued, the AD format has been revised, PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table: REVISED PARAGRAPH IDENTIFIERS Requirement in AD 2002–13–04 Corresponding requirement in this proposed AD paragraph (a) paragraph (b) paragraph (c) paragraph (f) paragraph (g) paragraph (h) Costs of Compliance We estimate that this proposed AD would affect 100 R–RM C–125, C–145, O–300, IO–360, TSIO–360, and LTSIO– 520–AE series reciprocating engines installed on airplanes of U.S. registry. We also estimate that it would take about 2 work-hours per engine to perform the inspections, and that the average labor rate is $85 per work-hour. Based on these figures, we estimate the total cost of the proposed AD to U.S. operators to be $17,000. Our cost estimate is exclusive of 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. E:\FR\FM\28JNP1.SGM 28JNP1 37684 Federal Register / Vol. 76, No. 124 / Tuesday, June 28, 2011 / Proposed Rules 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, Safety.

Airworthiness Directives; Teledyne Continental Motors (TCM) and 
Rolls-Royce Motors Ltd. (R-RM) Series Reciprocating Engines

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 certain TCM and R-RM series reciprocating engines. 
The existing AD currently requires replacement of certain magnetos if 
they fall within the specified serial number (S/N) range, inspection of 
the removed magneto to verify that the stop pin is still in place, and, 
if the stop pin is not in place, inspection of the engine gear train, 
crankcase, and accessory case. Since we issued that AD, we became aware 
of an error in the previous AD applicability in the range of magneto S/
Ns affected, and of the need to include certain engines made by R-RM, 
under license of TCM. This proposed AD would correct the range of S/Ns 
affected, require the same replacement and inspections, and would add 
R-RM C-125, C-145, O-300, IO-360, TSIO-360, and LTSIO-520-AE series 
reciprocating engines to the applicability. We are proposing this AD to 
correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by August 12, 2011.

Discussion

    On June 17, 2002, we issued AD 2002-13-04, Amendment 39-12792 (FR 
67 43230, June 27, 2002), for TCM C-125, C-145, O-300, IO-360, TSIO-
360, and LTSIO-520-AE series reciprocating engines. That AD requires, 
within 10 flight hours after the effective date of that AD, replacement 
of certain magnetos if they fall within the specified S/N range, 
inspection of the removed magneto to verify that the stop pin is still 
in place, and, if the stop pin is not in place, inspection of the 
engine gear train, crankcase, and accessory case. That AD resulted from 
reports of engine failures on certain TCM reciprocating engines. We 
issued that AD to prevent engine failure and loss of control of the 
airplane due to migration of the magneto impulse coupling stop pin out 
of the magneto frame and into the gear train of the engine.

Actions Since Existing AD Was Issued

    Since we issued AD 2002-13-04, we became aware of an error in the 
applicability paragraph of that AD, in the range of S/Ns affected. That 
AD applicability listed magneto S/Ns of 99110001 through 9912999 
inclusive. This proposed AD supersedure would correct the applicability 
to state magneto S/Ns of 99110001 through 99129999 inclusive, and add 
R-RM C-125, C-145, O-300, IO-360, TSIO-360, and LTSIO-520-AE series 
reciprocating engines built under license of TCM, to the applicability.

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 the same type design.

Proposed AD Requirements

    This proposed AD would retain all requirements of AD 2002-13-04. 
This proposed AD would also correct the range of S/Ns affected, and 
would add R-RM C-125, C-145, O-300, IO-360, TSIO-360, and LTSIO-520-AE 
series reciprocating engines to the applicability. Since AD 2002-13-04 
was issued, the AD format has been revised, and certain paragraphs have 
been rearranged. As a result, the corresponding paragraph identifiers 
have changed in this proposed AD, as listed in the following table:

                      Revised Paragraph Identifiers

                                     Corresponding  requirement in  this

          paragraph (a)                        paragraph (f)
          paragraph (b)                        paragraph (g)
          paragraph (c)                        paragraph (h)
------------------------------------------------------------------------

Costs of Compliance

    We estimate that this proposed AD would affect 100 R-RM C-125, C-
145, O-300, IO-360, TSIO-360, and LTSIO-520-AE series reciprocating 
engines installed on airplanes of U.S. registry. We also estimate that 
it would take about 2 work-hours per engine to perform the inspections, 
and that the average labor rate is $85 per work-hour. Based on these 
figures, we estimate the total cost of the proposed AD to U.S. 
operators to be $17,000. Our cost estimate is exclusive of 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.

[[Page 37684]]

    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, 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.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by removing airworthiness directive 
(AD) 2002-13-04, Amendment 39-12792 (67 FR 43230, June 27, 2002), and 
adding the following new AD:

    Teledyne Continental Motors (TCM) and Rolls-Royce Motors Ltd. 
(R-RM) Series Reciprocating Engines: Docket No. FAA-2011-0085; 
Directorate Identifier 2000-NE-19-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by August 12, 
2011.

(b) Affected ADs

    This AD supersedes AD 2002-13-04, Amendment 39-12792.

(c) Applicability

    This AD applies to TCM and R-RM C-125, C-145, O-300, IO-360, 
TSIO-360, and LTSIO-520-AE series reciprocating engines with 
Champion Aerospace (formerly Unison Industries) Slick Magnetos, 
models 6314, 6324, and 6364, with magneto serial numbers (S/Ns) of 
99110001 through 99129999 inclusive.

(d) Unsafe Condition

    This AD was prompted by an error in the previous AD 
applicability in the range of magneto S/Ns affected, and by the need 
to include certain engines made by R-RM, under license of TCM. We 
are issuing this AD to prevent engine failure and loss of control of 
the airplane due to migration of the magneto impulse coupling stop 
pin out of the magneto frame and into the gear train of the engine.

(e) Compliance

    Comply with this AD within 10 flight hours after the effective 
date of this AD, unless already done.

(f) Replacement of Magneto

    Replace any magneto that has a S/N of 99110001 through 99129999, 
inclusive, with a magneto that does not have a serial number in that 
range. If magneto is not in this S/N range, no further action is 
required by this AD.

(g) Inspections

    Inspect each removed magneto to verify that the impulse coupling 
stop pin is present. If the pin is missing, do the following:
    (1) For C-125, C-145, O-300, IO-360, and TSIO-360 series 
engines, do the following:
    (i) Remove magnetos, alternator or generator, and starter 
adapter from the accessory case.
    (ii) Remove the accessory case from the crankcase and oil sump.
    (iii) Visually inspect the entire engine gear train for damaged 
or broken gears and gear teeth.
    (iv) Inspect visible portions of the engine crankcase and 
accessory case for damage due to the stop pin becoming lodged 
between the engine gear train and the crankcase or accessory case.
    (v) If the accessory case is damaged, repair or replace the 
accessory case.
    (vi) If the engine crankcase is damaged, disassemble the engine, 
and repair or replace the crankcase.
    (vii) Inspect the oil pump drive gear teeth and inner cam gear 
teeth for damage. Replace any engine drive train component that has 
been damaged.
    (viii) Replace any damaged gear, and magnaflux the mating gears 
using the applicable engine overhaul manual.
    (2) For LTSIO-520-AE series engines, do the following:
    (i) Remove the starter adapter, fuel pump, vacuum pumps, 
accessory drive pads, and both magnetos.
    (ii) Visually inspect the entire engine gear train for damaged 
or broken gears and gear teeth.
    (iii) If any damage has occurred, remove the engine from the 
airplane, disassemble the engine, and inspect it for damage. If any 
damage is found, repair as necessary.
    (iv) Replace any damaged gear, and magnaflux the mating gears 
using the applicable engine overhaul manual.
    (v) Inspect the interior portions of the engine crankcase for 
damage due to the stop pin becoming lodged between the gear train 
and the crankcase. If the crankcase is damaged, repair or replace 
the crankcase.

(h) Installation Prohibition

    After the effective date of this AD, do not install any Champion 
Aerospace (formerly Unison Industries) Slick magnetos, model 6314, 
6324, or 6364 that have a S/N of 99110001 through 99129999 
inclusive, on any engine.

(i) Alternative Methods of Compliance

    The Manager, Atlanta Aircraft Certification Office, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19.

(j) Related Information

    (1) A cross-reference for part numbers (P/Ns) for Champion 
Aerospace (formerly Unison Industries) Slick magneto model 6314 (TCM 
P/N 653271), model 6324 (TCM P/N 653292), and model 6364 (TCM P/N 
649696) can be found in TCM Mandatory Service Bulletin MSB00-6D,
