Airworthiness Directives; Turbomeca S.A. Turboshaft Engines, 23830-23832 [2013-09349]

Download as PDF tkelley on DSK3SPTVN1PROD with RULES 23830 Federal Register / Vol. 78, No. 78 / Tuesday, April 23, 2013 / Rules and Regulations U.S. Commercial. This change provides greater flexibility to handlers in the marketing of the Colorado potato crop. Authority for this action is contained in §§ 948.21 and 948.22. This relaxation is expected to benefit the producers, handlers, and consumers of Colorado potatoes by allowing a greater quantity of fresh potatoes from the production area to enter the market. This anticipated increase in volume is expected to translate into greater returns for handlers and producers, and more purchasing options for consumers. This action is not expected to increase costs associated with the order requirements. Rather, this action makes additional product available to the market and has the potential to increase industry returns. The opportunities and benefits that may result from this rule are equally available to all Colorado potato handlers and producers, regardless of their size. In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35), the order’s information collection requirements have been previously approved by the Office of Management and Budget (OMB) and assigned OMB No. 0581–0178 (Generic Vegetable and Specialty Crops). No changes in those requirements as a result of this action are necessary. Should any changes become necessary, they would be submitted to OMB for approval. This rule will not impose any additional reporting or recordkeeping requirements on either small or large grapefruit handlers. As with all Federal marketing order programs, reports and forms are periodically reviewed to reduce information requirements and duplication by industry and public sector agencies. In addition, USDA has not identified any relevant Federal rules that duplicate, overlap or conflict with this rule. Further, the Committee’s meeting was widely publicized throughout the Colorado potato industry and all interested persons were invited to attend the meeting and participate in Committee deliberations. Like all Committee meetings, the July 19, 2012, meeting was a public meeting and all entities, both large and small, were able to express their views on this issue. Comments on the interim rule were required to be received on or before March 4, 2013. No comments were received. Therefore, for the reasons given in the interim rule, we are adopting the interim rule as a final rule, without change. To view the interim rule, go to: http://www.regulations.gov/ VerDate Mar<15>2010 14:43 Apr 22, 2013 Jkt 229001 #!documentDetail;D=AMS-FV-12-00430001. This action also affirms information contained in the interim rule concerning Executive Orders 12866 and 12988, the Paperwork Reduction Act (44 U.S.C. Chapter 35), and the E-Gov Act (44 U.S.C. 101). After consideration of all relevant material presented, it is found that finalizing the interim rule, without change, as published in the Federal Register (78 FR 3, January 2, 2013) will tend to effectuate the declared policy of the Act. List of Subjects in 7 CFR Part 948 Marketing agreements, Potatoes, Reporting and recordkeeping requirements. Accordingly, the interim rule that amended 7 CFR part 948 and was published at 78 FR 3 on January 2, 2013, is adopted as a final rule, without change. Dated: April 17, 2013. David R.

SUPPLEMENTARY INFORMATION: ADDRESSES: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on December 11, 2012 (77 FR 73557). That NPRM proposed to correct an unsafe condition for the specified products. The mandatory continuing airworthiness information (MCAI) states: Following detailed analysis and review of in-service feedback performed by Turbomeca on the Arriel 1 engines, the chapter 05–10 Airworthiness Limitation Section (ALS) of Arriel 1 Maintenance Manuals has been updated in order to clarify the definition and update the requirements relative to the cycle counting aid system (modification introduced in production by Turbomeca modification TU207 or TU243 and in-service, respectively, by Turbomeca Service Bulletin (SB) 292 80 0190 or SB 292 80 0168), add associated maintenance tasks, and modify the Power Turbine (PT) partial cycle counting method. The SBs referenced above introduced the tachometer. The tachometer’s cyclecounting feature, in some instances, produced results inconsistent with ground run checks. The inaccurate cycle-counting results of the tachometer can lead to exceeding life limits on critical rotating parts, which can cause uncontained engine failure and damage to the helicopter. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (77 FR 73557, December 11, 2012). Actions Since We Issued the Proposed Rule Since we issued the NPRM (77 FR 73557, December 11, 2012), the European Aviation Safety Agency (EASA) issued revised MCAI (EASA AD 2012–0187R2, dated December 6, 2012), which states that for affected engines that have a tachometer installed, but the E:\FR\FM\23APR1.SGM 23APR1 Federal Register / Vol. 78, No. 78 / Tuesday, April 23, 2013 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES tachometer is not used to count cycles, then no further action is required. Changes to Actions and Compliance Section of This AD We evaluated the revised MCAI (EASA AD 2012–0187R2, dated December 6, 2012), and we agree that for affected engines that have a tachometer installed, but the tachometer is not used to count cycles, then no further compliance action is required. We changed paragraph (e) of the final rule by inserting a new paragraph (e)(1) to read: ‘‘(1) If a tachometer is installed on the engine, but is not used to count cycles, then no further action is required.’’ We also changed paragraph (e)(2) of this AD to clarify the objective of the daily check. The objective is not only to compare the cycle-count values from the tachometer and the daily check, but also to verify that they agree. The NPRM (77 FR 73557, December 11, 2012) stated: ‘‘During the post flight maintenance inspection after the last flight of each day, compare the cycles counted by the engine’s tachometer unit with the cycles counted by the primary counting method.’’ The changed paragraph in this AD states: ‘‘During the post-flight maintenance inspection after the last flight of each day, verify that the cycles counted by the engine’s tachometer unit agree with the cycles counted by the primary counting method.’’ We also changed paragraph (e)(4) of this AD to clearly state that the groundrun functional check required every 1,000 operating hours is in addition to the daily inspections required by this AD. The NPRM (77 FR 73557, December 11, 2012) stated: ‘‘If the engine tachometer cyclecounting feature remains accurate, then every 1,000 operating hours, perform a ground-run functional check of the tachometer unit cycle-counting feature.’’ The changed paragraph in this AD states: ‘‘If the engine tachometer cyclecounting feature remains accurate, then every 1,000 operating hours, perform a ground-run functional check of the tachometer unit cycle-counting feature in addition to the daily inspections required in paragraph (e)(2) of this AD. If the tachometer cycle-counting feature fails the check, thereafter, use only the primary cycle-counting method to count cycles.’’ Changes to Cost of Compliance We also changed the Costs of Compliance section of this AD. Paragraph (e)(4) of this AD requires a VerDate Mar<15>2010 14:43 Apr 22, 2013 Jkt 229001 functional check of the tachometer cycle counting feature every 1,000 operating hours. The NPRM (77 FR 73557, December 11, 2012) did not include the cost of the functional check in the estimated annual costs of compliance, while this AD does include that cost. The fleet cost for the functional check every 1,000 operating hours is $181,050, bringing the new total estimated fleet cost of compliance for this AD to $19,493,050. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that the changes we have made, that is, the change based on revised MCAI and the editorial changes made to improve clarity, will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance We estimate that this AD will affect about 1,420 engines installed in helicopters of U.S. registry. We do not have an estimate of how many engine tachometers will fail the inspection, so we have estimated the cost of repetitive inspections of engine tachometer units for one year and the cost of a required 1000-hour functional check. We estimate that an average of 320 checks will be required per year, and that it will take about 30 minutes per engine to perform a check of the engine’s tachometer unit cycle-counting feature. We estimate the 1,000-operating-hour functional check to take 1.5 hours to complete. The average labor rate is $85 per hour. No parts will be required. Based on these figures, we estimate the total cost of the AD on U.S. operators to be $19,493,050. 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 PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 23831 that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings We 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 this AD: (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); and (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. Examining the AD Docket You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information.

SUPPLEMENTARY INFORMATION: SUMMARY: PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 I. Background The Energy Policy Act of 1992 (EPAct 92 or Act) established federal programs to encourage the development of alternative fuels and alternative fueled vehicles (AFVs). Section 406(a) of the Act directed the Commission to establish uniform labeling requirements for alternative fuels and AFVs. Under the Act, such labels must provide ‘‘appropriate information with respect to costs and benefits [of alternative fuels and AFVs], so as to reasonably enable the consumer to make choices and comparisons.’’ 1 In addition, the required labels must be ‘‘simple and, where appropriate, consolidated with other labels providing information to the consumer.’’ 2 In response to EPAct 92, the Commission published the Alternative Fuels Rule in 1995.3 The Rule requires labels on new and used AFVs that run on liquid and non-liquid fuels, such as ethanol and other alcohols, including E85 ethanol-gasoline mixtures, natural gas, liquefied petroleum gas, hydrogen, coal-derived liquid fuels, fuels derived from biological materials (e.g., 100% biodiesel), and electricity. The labels for new AFVs disclose the vehicle’s estimated driving range (i.e., the travel distance on a single charge or tank of fuel), general factors consumers should consider before buying an AFV, and toll-free telephone numbers and Web sites for additional information from the Department of Energy (DOE) and NHTSA.4 Labels for used AFVs contain only the general buying factors and DOE/NHTSA contact information.5 The Rule also requires labels on fuel dispensers for non-liquid alternative fuels, such as electricity, compressed natural gas, and hydrogen. The labels for electricity provide the charging system’s kilowatt capacity, voltage, and other related information. The labels for other non-liquid fuels disclose the fuel’s commonly used name and principal component (expressed as a percentage). II. Regulatory Review In a 2011 Advance Notice of Proposed Rulemaking (ANPR), the Commission initiated its regulatory review of the Alternative Fuels Rule to, among other 1 42 U.S.C. 13232(a). 2 Id. 3 60 FR 26926 (May 19, 1995). Rule requires manufacturers to have a reasonable basis for the vehicle cruising range, and, for certain AFVs, specifies the test method for calculating that range. 16 CFR 309.22. 5 The general factors listed on the current label include fuel type, operating costs, fuel availability, performance, convenience, energy security, energy renewability, and emissions.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 
1S, and 1S1 turboshaft engines. This AD requires daily post-flight 
checks of the engine tachometer's unit cycle-counting feature. This AD 
also requires ground-run functional checks within every 1,000 operating 
hours. This AD was prompted by detailed analysis and review of the 
accuracy of the engine's tachometer cycle-counting feature. We are 
issuing this AD to prevent uncontained engine failure and damage to the 
helicopter.

DATES: This AD becomes effective May 28, 2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on December 11, 2012 
(77 FR 73557). That NPRM proposed to correct an unsafe condition for 
the specified products. The mandatory continuing airworthiness 
information (MCAI) states:

    Following detailed analysis and review of in-service feedback 
performed by Turbomeca on the Arriel 1 engines, the chapter 05-10 
Airworthiness Limitation Section (ALS) of Arriel 1 Maintenance 
Manuals has been updated in order to clarify the definition and 
update the requirements relative to the cycle counting aid system 
(modification introduced in production by Turbomeca modification 
TU207 or TU243 and in-service, respectively, by Turbomeca Service 
Bulletin (SB) 292 80 0190 or SB 292 80 0168), add associated 
maintenance tasks, and modify the Power Turbine (PT) partial cycle 
counting method.

    The SBs referenced above introduced the tachometer. The 
tachometer's cycle-counting feature, in some instances, produced 
results inconsistent with ground run checks. The inaccurate cycle-
counting results of the tachometer can lead to exceeding life limits on 
critical rotating parts, which can cause uncontained engine failure and 
damage to the helicopter.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 73557, December 11, 
2012).

Actions Since We Issued the Proposed Rule

    Since we issued the NPRM (77 FR 73557, December 11, 2012), the 
European Aviation Safety Agency (EASA) issued revised MCAI (EASA AD 
2012-0187R2, dated December 6, 2012), which states that for affected 
engines that have a tachometer installed, but the

[[Page 23831]]

tachometer is not used to count cycles, then no further action is 
required.

Changes to Actions and Compliance Section of This AD

    We evaluated the revised MCAI (EASA AD 2012-0187R2, dated December 
6, 2012), and we agree that for affected engines that have a tachometer 
installed, but the tachometer is not used to count cycles, then no 
further compliance action is required. We changed paragraph (e) of the 
final rule by inserting a new paragraph (e)(1) to read:
    ``(1) If a tachometer is installed on the engine, but is not used 
to count cycles, then no further action is required.''
    We also changed paragraph (e)(2) of this AD to clarify the 
objective of the daily check. The objective is not only to compare the 
cycle-count values from the tachometer and the daily check, but also to 
verify that they agree. The NPRM (77 FR 73557, December 11, 2012) 
stated:
    ``During the post flight maintenance inspection after the last 
flight of each day, compare the cycles counted by the engine's 
tachometer unit with the cycles counted by the primary counting 
method.''
    The changed paragraph in this AD states:
    ``During the post-flight maintenance inspection after the last 
flight of each day, verify that the cycles counted by the engine's 
tachometer unit agree with the cycles counted by the primary counting 
method.''
    We also changed paragraph (e)(4) of this AD to clearly state that 
the ground-run functional check required every 1,000 operating hours is 
in addition to the daily inspections required by this AD. The NPRM (77 
FR 73557, December 11, 2012) stated:
    ``If the engine tachometer cycle-counting feature remains accurate, 
then every 1,000 operating hours, perform a ground-run functional check 
of the tachometer unit cycle-counting feature.''
    The changed paragraph in this AD states:
    ``If the engine tachometer cycle-counting feature remains accurate, 
then every 1,000 operating hours, perform a ground-run functional check 
of the tachometer unit cycle-counting feature in addition to the daily 
inspections required in paragraph (e)(2) of this AD. If the tachometer 
cycle-counting feature fails the check, thereafter, use only the 
primary cycle-counting method to count cycles.''

Changes to Cost of Compliance

    We also changed the Costs of Compliance section of this AD. 
Paragraph (e)(4) of this AD requires a functional check of the 
tachometer cycle counting feature every 1,000 operating hours. The NPRM 
(77 FR 73557, December 11, 2012) did not include the cost of the 
functional check in the estimated annual costs of compliance, while 
this AD does include that cost. The fleet cost for the functional check 
every 1,000 operating hours is $181,050, bringing the new total 
estimated fleet cost of compliance for this AD to $19,493,050.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We determined that the changes we have made, that is, the 
change based on revised MCAI and the editorial changes made to improve 
clarity, will not increase the economic burden on any operator or 
increase the scope of the AD.

Costs of Compliance

    We estimate that this AD will affect about 1,420 engines installed 
in helicopters of U.S. registry. We do not have an estimate of how many 
engine tachometers will fail the inspection, so we have estimated the 
cost of repetitive inspections of engine tachometer units for one year 
and the cost of a required 1000-hour functional check. We estimate that 
an average of 320 checks will be required per year, and that it will 
take about 30 minutes per engine to perform a check of the engine's 
tachometer unit cycle-counting feature. We estimate the 1,000-
operating-hour functional check to take 1.5 hours to complete. The 
average labor rate is $85 per hour. No parts will be required. Based on 
these figures, we estimate the total cost of the AD on U.S. operators 
to be $19,493,050.

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 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 this AD:
    (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); and
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


[[Page 23832]]




Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2013-08-22 Turbomeca S.A.: Amendment 39-17440; Docket No. FAA-2012-
1131; Directorate Identifier 2012-NE-34-AD.

(a) Effective Date

    This AD becomes effective May 28, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Turbomeca S.A. Arriel 1A1, 1A2, 1B, 1C, 1C1, 
1C2, 1D, 1D1, 1E2, 1K1, 1S, and 1S1 turboshaft engines that have 
incorporated Modification TU 207 or TU 243, or have incorporated 
Turbomeca Service Bulletin (SB) No. 292 80 0168 or SB No. 292 80 
0190.

(d) Reason

    This AD was prompted by detailed analysis and review of the 
accuracy of the engine's tachometer cycle-counting feature. We are 
issuing this AD to prevent uncontained engine failure and damage to 
the helicopter.

(e) Actions and Compliance

    (1) If a tachometer is installed on the engine, but is not used 
to count cycles, then no further action is required.
    (2) During the post-flight maintenance inspection after the last 
flight of each day, verify that the cycles counted by the engine's 
tachometer unit agree with the cycles counted by the primary 
counting method.
    (3) If the numbers are different, use the primary counting 
method thereafter to determine all cycle counts. Do not use the 
values from the tachometer cycle-counting feature.
    (4) If the engine tachometer cycle-counting feature remains 
accurate, then every 1,000 operating hours, perform a ground-run 
functional check of the tachometer unit cycle-counting feature in 
addition to the daily inspections in paragraph (e)(2) of this AD. If 
the tachometer cycle-counting feature fails the check, thereafter, 
use only the primary cycle-counting method to count cycles.
    (5) If the tachometer is replaced, follow the instructions in 
paragraphs (e)(2), (e)(3), and (e)(4) of this AD.

(f) 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.
