Airworthiness Directives; Turbomeca S.A. Turboshaft Engines, 8092-8094 [2012-3255]

Download as PDF 8092 Federal Register / Vol. 77, No. 30 / Tuesday, February 14, 2012 / Rules and Regulations annotation does not specify the plant source of lecithin and, therefore, nonorganic de-oiled lecithin from nonsoy and nonorganic sources may be used when organic equivalents are not available. A substance is considered commercially available if it is available in an appropriate form, quality, or quantity to fulfill an essential function in a system of organic production or handling, as determined by the certifying agent in the course of reviewing the organic plan. In summary, this annotation change would not limit the use of lecithin to organic de-oiled soy lecithin. Non-soy sources that are non-GMO and nonorganic would remain acceptable under § 205.606, and accredited certifying agents would continue to require any nonorganic deoiled lecithin to be sourced from nonGMO sources as long as de-oiled lecithin is not commercially available in organic form. Changes Requested But Not Made Commenters requested that the proposed action be amended for § 205.606 to allow the use of non-GMO, non-allergenic lecithin. We have not made that change because we believe this request is mostly accommodated by the proposed action. Nonorganic forms of de-oiled lecithin can be used when the organic version is not commercially available. The NOP regulations define commercially available as a production input in an appropriate form, quality, or quantity to fulfill an essential function in a system of organic production or handling, as determined by the certifying agent in the course of reviewing the organic plan. Therefore, if a processor intends to make a soy-free product containing lecithin, in which de-oiled is the appropriate form, the processor may use nonorganic de-oiled lecithin from sunflower, canola or other sources if lecithin from the preferred sources is not available in organic form. If a product requires a form of lecithin other than de-oiled, such as fluid or powered, the lecithin must be sourced organically. The NOSB recommendation was finalized in May 2009. We believe that processors have had adequate notice to pursue the procurement of non-soy forms of organic lecithin if their products are intended to be soy free. pmangrum on DSK3VPTVN1PROD with RULES List of Subjects in 7 CFR Part 205 14:25 Feb 13, 2012 Jkt 226001 PART 205—NATIONAL ORGANIC PROGRAM 1.

Turboshaft Engines Federal Aviation Administration (FAA), DOT. ACTION: Final rule. AGENCY: We are superseding an existing airworthiness directive (AD) for all Turbomeca S.A. Arriel 2B and 2B1 turboshaft engines. That AD currently requires checking the transmissible torque between the low-pressure (LP) pump impeller and the high-pressure (HP) pump shaft on high-pressure/lowpressure (HP/LP) pump hydromechanical metering units (HMUs) that do not incorporate Modification TU 147. This new AD requires inspection and possible replacement of the HMU. This AD was prompted by three additional cases of uncoupling of the HP/LP pump HMU LP fuel pump impeller and the HP fuel pump shaft, since the existing AD was issued. We are issuing this AD to prevent an uncommanded in-flight shutdown, which can result in a forced autorotation landing or accident. DATES: This AD is effective March 20, 2012. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 20, 2012. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of March 11, 2010 (75 FR 5689, February 4, 2010).

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2010–03–06, Amendment 39–16189 (75 FR 5689, February 4, 2010). That AD applies to the specified products. The NPRM published in the Federal Register on November 7, 2011 (76 FR 68661). That NPRM proposed to require inspection and possible replacement of the HMU. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comment received on the proposal and the FAA’s response to that comment. pmangrum on DSK3VPTVN1PROD with RULES Claim That the Shop Rate Is Too Low One commenter, Advanced Helicopter Services, claimed that our shop rate in the proposed AD was too low. We do not agree. We used the hourly labor rate determined by the Office of Management and Budget. We did not change the AD. Clarification of Paragraph (e)(1)(ii) Since we issued the NPRM (76 FR 68661, November 7, 2011), we determined that paragraph (e)(1)(ii) was unclear and made changes to clarify the population affected. We also reformatted the compliance instruction in this paragraph for clarity. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting the AD with the change described previously. VerDate Mar<15>2010 14:25 Feb 13, 2012 Jkt 226001 Costs of Compliance Based on the service information, we estimate that this AD will affect about 540 engines installed on helicopters of U.S. registry. We also estimate that it will take about 2.5 work-hours per engine to comply with this AD. The average labor rate is $85 per work-hour. Replacement HMUs will cost about $12,000 per engine. Based on these figures, if all of the HMUs were to fail the check, we estimate the cost of the AD on U.S. operators to be $6,594,750. 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 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.

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) 2010–03–06, Amendment 39–16189 (75 FR 5689, February 4, 2010), and adding the following new AD: ■ 2012–03–11 Turbomeca S.A.: Amendment 39–16953; Docket No. FAA–2009–0889; Directorate Identifier 2009–NE–35–AD. (a) Effective Date This airworthiness directive (AD) is effective March 20, 2012. (b) Affected ADs This AD supersedes AD 2010–03–06, Amendment 39–16189 (75 FR 5689, February 4, 2010). (c) Applicability This AD applies to all Turbomeca S.A. Arriel 2B and 2B1 turboshaft engines. (d) Unsafe Condition This AD was prompted by three additional cases of uncoupling of the high-pressure/lowpressure (HP/LP) pump hydro-mechanical metering unit (HMU) low-pressure (LP) fuel pump impeller and the high-pressure (HP) fuel pump shaft, since AD 2010–03–06 (75 FR 5689, February 4, 2010) was issued. However, these failures were in HMUs that were modified to post-TU 147 configuration HMUs. The investigation indicates that these HMUs may also need to be replaced. We are issuing this AD to prevent an uncommanded in-flight shutdown, which can result in a forced autorotation landing or accident. (e) Compliance Comply with this AD within the compliance times specified, unless already done. (1) Check the transmissible torque between the LP fuel pump impeller and the HP fuel pump shaft as follows: (i) For HMUs that do not incorporate Modification TU 147, check the torque before accumulating 500 engine flight hours (EFH) since March 11, 2010 (the effective date of AD 2010–03–06 (75 FR 5689, February 4, 2010)). Use Paragraph 2 of Turbomeca Alert Mandatory Service Bulletin (MSB) No. A292 73 2830, Version B, dated July 10, 2009, to do the check. (ii) For HMUs that incorporated Modification TU 147 on or before March 31, 2010 and those HMUs that are not listed in Figures 2 or 3 of Turbomeca Alert MSB No. A292 73 2836, Version A, dated August 17, 2010: E:\FR\FM\14FER1.SGM 14FER1 8094 Federal Register / Vol. 77, No. 30 / Tuesday, February 14, 2012 / Rules and Regulations (A) Check the torque within 750 EFH from the effective date of this AD, but no later than 14 months after the effective date of this AD. (B) Use Paragraph 2 of Turbomeca Alert MSB No. A292 73 2836, Version A, dated August 17, 2010, to do the check. (2) If the HMU does not pass the torque check, then replace the HMU with an HMU that is eligible for installation. (f) HMU Reinstallation Do not install any HMU removed from service by this AD until it has been checked in accordance with Paragraph 2 of Turbomeca Alert MSB No. A292 73 2836, Version A, dated August 17, 2010, or checked in accordance with Paragraph 2 of Turbomeca Alert MSB No. A292 73 2830, Version B, dated July 10, 2009, and found eligible for installation.

SUMMARY: FOR FURTHER INFORMATION CONTACT: (i) Material Incorporated by Reference VerDate Mar<15>2010 Issued in Burlington, Massachusetts, on February 6, 2012. Peter A.

Mary Beth Sullivan, Counsel, Office of the Inspector General, at (202) 551– 6039, Securities and Exchange Commission, 100 F Street NE., Washington, DC 20549. SUPPLEMENTARY INFORMATION: I. Discussion Section 8G(d)(1) of the Inspector General Act of 1978 (‘‘IG Act’’) 1 provides: ‘‘Each Inspector General shall report to and be under the general supervision of the head of the designated Federal entity, but shall not report to, or be subject to supervision by, any other officer or employee of such designated Federal entity.’’ Prior to the Dodd-Frank Wall Street Reform and Consumer Protection Act (‘‘Dodd-Frank Act’’),2 section 8G(a)(4) of the IG Act defined the ‘‘head of the designated Federal entity’’ to mean, unless specifically designated by statute, the chief policymaking officer or board of the designated Federal entity as identified in a list published annually by the Director of the Office of Management and Budget (‘‘OMB’’). OMB’s annual lists identified the ‘‘Chairperson’’ as the head of the SEC. Section 989B of the Dodd-Frank Act amended the IG Act to provide that the ‘‘head of the designated Federal entity’’ with a board or commission (such as the SEC) means ‘‘the board or commission of the designated Federal entity * * * .’’ Accordingly, the Inspector General must now report to, and be under the general supervision of, the full Commission. These amendments conform the Commission’s rules that address the reporting line of the Commission’s Inspector General to the amendments made by the Dodd-Frank Act to the IG Act by replacing references to the ‘‘Chairman’’ in these rules with references to the ‘‘Commission’’. II. Related Matters A. Administrative Procedure Act and Other Administrative Laws The Commission has determined that these amendments to its rules relate solely to the agency’s organization, procedure, or practice. Accordingly, the provisions of the Administrative Procedure Act regarding notice of proposed rulemaking and opportunity for public participation are not applicable.3 The Regulatory Flexibility Act, therefore, does not apply.4 Because these rules relate solely to the agency’s organization, procedure, or practice and do not substantially affect the rights or obligations of non-agency parties, they are not subject to the Small Business Regulatory Enforcement Fairness Act.5 Finally, these amendments do not contain any collection of information requirements as defined by the Paperwork Reduction Act of 1995, as amended.6 B. Cost-Benefit Analysis The Commission is sensitive to the costs and benefits imposed by its rules. The amendments adopted today are procedural in nature and will produce the benefit of conforming the Commission’s rules to amendments made to the IG Act that require the Commission’s Inspector General to report to and be under the general supervision of the full Commission. The Commission also believes that these amendments will not impose any costs on non-agency parties, or that if there are any such costs, they are negligible. C. Consideration of Burden on Competition Section 23(a)(2) of the Exchange Act requires the Commission, in making rules pursuant to any provision of the Exchange Act, to consider among other 35 1 Public Law 95–452; 92 Stat. 1101 (1978), as amended. 2 Public Law 111–203; 124 Stat. 1376 (2010).

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for all Turbomeca S.A. Arriel 2B and 2B1 turboshaft engines. That AD 
currently requires checking the transmissible torque between the low-
pressure (LP) pump impeller and the high-pressure (HP) pump shaft on 
high-pressure/low-pressure (HP/LP) pump hydro-mechanical metering units 
(HMUs) that do not incorporate Modification TU 147. This new AD 
requires inspection and possible replacement of the HMU. This AD was 
prompted by three additional cases of uncoupling of the HP/LP pump HMU 
LP fuel pump impeller and the HP fuel pump shaft, since the existing AD 
was issued. We are issuing this AD to prevent an uncommanded in-flight 
shutdown, which can result in a forced autorotation landing or 
accident.

DATES: This AD is effective March 20, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of March 20, 
2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of March 
11, 2010 (75 FR 5689, February 4, 2010).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2010-03-06, Amendment 39-16189 (75 FR 5689, 
February 4, 2010). That AD applies to the specified products. The NPRM 
published in the Federal Register on November 7, 2011 (76 FR 68661). 
That NPRM proposed to require inspection and possible replacement of 
the HMU.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comment received on the proposal 
and the FAA's response to that comment.

Claim That the Shop Rate Is Too Low

    One commenter, Advanced Helicopter Services, claimed that our shop 
rate in the proposed AD was too low.
    We do not agree. We used the hourly labor rate determined by the 
Office of Management and Budget. We did not change the AD.

Clarification of Paragraph (e)(1)(ii)

    Since we issued the NPRM (76 FR 68661, November 7, 2011), we 
determined that paragraph (e)(1)(ii) was unclear and made changes to 
clarify the population affected. We also reformatted the compliance 
instruction in this paragraph for clarity.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the change described previously.

Costs of Compliance

    Based on the service information, we estimate that this AD will 
affect about 540 engines installed on helicopters of U.S. registry. We 
also estimate that it will take about 2.5 work-hours per engine to 
comply with this AD. The average labor rate is $85 per work-hour. 
Replacement HMUs will cost about $12,000 per engine. Based on these 
figures, if all of the HMUs were to fail the check, we estimate the 
cost of the AD on U.S. operators to be $6,594,750.

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 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.

    This AD supersedes AD 2010-03-06, Amendment 39-16189 (75 FR 
5689, February 4, 2010).

(c) Applicability

    This AD applies to all Turbomeca S.A. Arriel 2B and 2B1 
turboshaft engines.

(d) Unsafe Condition

    This AD was prompted by three additional cases of uncoupling of 
the high-pressure/low-pressure (HP/LP) pump hydro-mechanical 
metering unit (HMU) low-pressure (LP) fuel pump impeller and the 
high-pressure (HP) fuel pump shaft, since AD 2010-03-06 (75 FR 5689, 
February 4, 2010) was issued. However, these failures were in HMUs 
that were modified to post-TU 147 configuration HMUs. The 
investigation indicates that these HMUs may also need to be 
replaced. We are issuing this AD to prevent an uncommanded in-flight 
shutdown, which can result in a forced autorotation landing or 
accident.

(e) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) Check the transmissible torque between the LP fuel pump 
impeller and the HP fuel pump shaft as follows:
    (i) For HMUs that do not incorporate Modification TU 147, check 
the torque before accumulating 500 engine flight hours (EFH) since 
March 11, 2010 (the effective date of AD 2010-03-06 (75 FR 5689, 
February 4, 2010)). Use Paragraph 2 of Turbomeca Alert Mandatory 
Service Bulletin (MSB) No. A292 73 2830, Version B, dated July 10, 
2009, to do the check.
    (ii) For HMUs that incorporated Modification TU 147 on or before 
March 31, 2010 and those HMUs that are not listed in Figures 2 or 3 
of Turbomeca Alert MSB No. A292 73 2836, Version A, dated August 17, 
2010:

[[Page 8094]]

    (A) Check the torque within 750 EFH from the effective date of 
this AD, but no later than 14 months after the effective date of 
this AD.
    (B) Use Paragraph 2 of Turbomeca Alert MSB No. A292 73 2836, 
Version A, dated August 17, 2010, to do the check.
    (2) If the HMU does not pass the torque check, then replace the 
HMU with an HMU that is eligible for installation.

(f) HMU Reinstallation

    Do not install any HMU removed from service by this AD until it 
has been checked in accordance with Paragraph 2 of Turbomeca Alert 
MSB No. A292 73 2836, Version A, dated August 17, 2010, or checked 
in accordance with Paragraph 2 of Turbomeca Alert MSB No. A292 73 
2830, Version B, dated July 10, 2009, and found eligible for 
installation.

(g) 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.
