Airworthiness Directives; Turbomeca Model Arriel 1E2, 1S, and 1S1 Turboshaft Engines, 11940-11942 [2011-4832]

Download as PDF jdjones on DSK8KYBLC1PROD with RULES2 11940 Federal Register / Vol. 76, No. 43 / Friday, March 4, 2011 / Rules and Regulations to which the Order overlaps, duplicates, or conflicts with other Federal rules, and, to the extent feasible, with State and local regulations; and (5) the length of time since the Order has been evaluated or the degree to which technology, economic conditions, or other factors have changed in the area affected by the Order. Based on its review, the Department has concluded that there is a continued need for the Order. According to the Council’s World Blueberry Acreage and Production Report, highbush blueberry acreage in North America increased from 71,075 acres in 2005 to an estimated 95,607 acres in 2008, a 35 percent increase in just three years. The United States share of this total increased from 56,665 acres in 2005 to 74,992 acres in 2008, a 32 percent increase. Highbush blueberry production volume is expected to increase significantly in the coming years. Regarding the nature of complaints or comments received from the public concerning the Order, as previously mentioned twenty comments were received. They are discussed in the following paragraphs. One commenter opposed the program stating that government funds should not be used to market blueberries. However, the blueberry program is funded by producers and importers of blueberries. The program is developed by the industry to expand the markets for blueberries in the United States. Nineteen commenters supported the program and considered it to be effective in promoting blueberries. All the commenters stated that the program is needed to increase blueberry consumption due to increase blueberry production. One commenter stated that investing in promotion now to build a future is necessary even in poor economic conditions. Twelve commenters in favor of the program stated that further research of blueberries is needed to stay competitive in a global industry. Six commenters stated the program is needed to develop health claims for blueberries. One commenter who supports the program stated that the ability for growers from different production areas to work together in an effort to increase consumption through product research and marketing programs has proven effective for many other crops. Ten commenters stated that the assessment dollars are collected fairly from all U.S. production and imports and the Council utilizes the funds in a cost effective manner. VerDate Mar<15>2010 13:26 Mar 03, 2011 Jkt 223001 AMS provides Federal oversight of the blueberry program. The Order is not unduly complex, and AMS has not identified any Federal rules, or State and local regulations that duplicate, overlap, or conflict with the Order. Over the years, regulatory changes have been made to address industry operation changes and to improve program administration. Regarding evaluations of the program or the degree to which technology, economic conditions, or other factors have changed in the area affected by the Order, section 512 (a)(6) of the Act and section 1218.55 of the Order require the Council to evaluate the program and to comply with the independent evaluation provision of the Federal Agricultural Improvement and Reform Act of 1996 (FAIR) [7 U.S.C. 7201]. The goal of these evaluations is to assure that the Order and the regulations implemented under it fit the needs of the industry and are consistent with the Act. The Council conducted an evaluation of the program under the FAIR in 2006. This evaluation, ‘‘An Economic Analysis of Domestic Market Impacts of the U.S. Highbush Blueberry Council,’’ concluded that the promotional spending by the Council clearly had a positive effect on demand. The next evaluation is scheduled to be conducted late in 2011. Based upon its review, AMS has determined that the Order should be continued. AMS plans to continue working with the blueberry industry in maintaining an effective program. Dated: February 25, 2011. David R. Shipman, Acting Administrator, Agricultural Marketing Service.

ACTION: Final rule; request for comments. AGENCY: PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 This action supersedes emergency airworthiness directive (AD) 2011–05–51 that was sent previously to all known U.S. owners and operators of the products listed above. That AD requires inspecting the fuel ejector in the body of the fuel ejector assembly for proper installation by checking that the circlip is properly seated in its groove. That AD was prompted by three reports of incorrectly assembled low-pressure fuel system ejectors; with one of them resulting in an uncommanded engine in-flight shutdown. This AD requires the same actions and compliance times as the emergency AD, after receipt of the emergency AD, and expands the AD applicability by including helicopters having one or two affected engines and experiencing no starting difficulties. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: SUMMARY: In October 2009, Turbomeca issued SB [Service Bulletin] No. 292 73 0826, Version A that instructed operators to check the effectiveness of the bonding of the ejector jet installed on the low-pressure fuel system between the tank and the high-pressure fuel pump. So far, Turbomeca have been informed of three discrepancies with the reassembly of the ejector following a maintenance procedure performed during accomplishment of Turbomeca SB No. 292 73 0826, Version A. In all three cases, the discrepancies led to a ‘‘one-off’’ abnormal evolution of gas generator (NG) rating during engine starting. In one of these cases, this resulted in an uncommanded in-flight shutdown, during a cruising phase at 8,000 feet. We are issuing this AD to prevent uncommanded engine in-flight shutdown of one or both engines in a two-engine helicopter and an emergency autorotation landing or accident. DATES: This AD becomes effective March 9, 2011. We must receive comments on this AD by April 4, 2011. The Director of the Federal Register approved the incorporation by reference of Turbomeca Mandatory Service Bulletin (MSB) No. A292 73 0834, Version B, dated February 8, 2011, listed in the AD as of March 9, 2011.

SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive EASA AD No. 2011–0023–E, dated February 9, 2011 (corrected on February 10, 2011) (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: jdjones on DSK8KYBLC1PROD with RULES2 In October 2009, Turbomeca issued SB [Service Bulletin] No. 292 73 0826, Version A that instructed operators to check the effectiveness of the bonding of the ejector jet installed on the low-pressure fuel system between the tank and the high-pressure fuel pump.

In one of these cases, this resulted in an uncommanded in-flight shutdown, during a cruising phase at 8,000 feet. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information We reviewed Turbomeca MSB No. A292 73 0834, Version B, dated February 8, 2011, and SB No. 292 73 VerDate Mar<15>2010 13:26 Mar 03, 2011 Jkt 223001 0826, Version B, dated February 4, 2011. This service information describes procedures for inspecting for proper ejector installation. FAA’s Determination and Requirements of This AD This product has been approved by the aviation authority of France, and is approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. This AD requires inspecting the fuel ejector in the body of the fuel ejector assembly for proper installation by checking that the circlip is properly seated in its groove, for all affected engines. This AD requires the same actions and compliance times as emergency AD 2011–05–51, after receipt of the emergency AD, and expands the AD applicability by including helicopters having one or two affected engines and experiencing no starting difficulties. FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because of the high risk of uncommanded engine in-flight shutdown of one or both engines in a two-engine helicopter and an emergency autorotation landing or accident. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2011–0141; Directorate Identifier 2011–NE–06–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this 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 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 11941 will also post a report summarizing each substantive verbal contact with FAA personnel concerning this AD. Using the search function of the Web site, anyone can find and read the comments in any of our dockets, including, if provided, the name of the individual who sent the comment (or signed the comment on behalf of an association, business, labor union, etc.). You may review the DOT’s complete Privacy Act Statement in the Federal Register published on April 11, 2000 (65 FR 19477–78). 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 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 AD and placed it in the AD docket.

Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This action supersedes emergency airworthiness directive (AD) 
2011-05-51 that was sent previously to all known U.S. owners and 
operators of the products listed above. That AD requires inspecting the 
fuel ejector in the body of the fuel ejector assembly for proper 
installation by checking that the circlip is properly seated in its 
groove. That AD was prompted by three reports of incorrectly assembled 
low-pressure fuel system ejectors; with one of them resulting in an 
uncommanded engine in-flight shutdown. This AD requires the same 
actions and compliance times as the emergency AD, after receipt of the 
emergency AD, and expands the AD applicability by including helicopters 
having one or two affected engines and experiencing no starting 
difficulties. This AD results from mandatory continuing airworthiness 
information (MCAI) issued by an aviation authority of another country 
to identify and correct an unsafe condition on an aviation product. The 
MCAI describes the unsafe condition as:

    In October 2009, Turbomeca issued SB [Service Bulletin] No. 292 
73 0826, Version A that instructed operators to check the 
effectiveness of the bonding of the ejector jet installed on the 
low-pressure fuel system between the tank and the high-pressure fuel 
pump.
    So far, Turbomeca have been informed of three discrepancies with 
the reassembly of the ejector following a maintenance procedure 
performed during accomplishment of Turbomeca SB No. 292 73 0826, 
Version A.
    In all three cases, the discrepancies led to a ``one-off'' 
abnormal evolution of gas generator (NG) rating during engine 
starting. In one of these cases, this resulted in an uncommanded in-
flight shutdown, during a cruising phase at 8,000 feet.

    We are issuing this AD to prevent uncommanded engine in-flight 
shutdown of one or both engines in a two-engine helicopter and an 
emergency autorotation landing or accident.

DATES: This AD becomes effective March 9, 2011.
    We must receive comments on this AD by April 4, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of Turbomeca Mandatory Service Bulletin (MSB) No. A292 73 
0834, Version B, dated February 8, 2011, listed in the AD as of March 
9, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive EASA AD No. 2011-0023-E, dated February 9, 2011 
(corrected on February 10, 2011) (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    In October 2009, Turbomeca issued SB [Service Bulletin] No. 292 
73 0826, Version A that instructed operators to check the 
effectiveness of the bonding of the ejector jet installed on the 
low-pressure fuel system between the tank and the high-pressure fuel 
pump.
    So far, Turbomeca have been informed of three discrepancies with 
the reassembly of the ejector following a maintenance procedure 
performed during accomplishment of Turbomeca SB No. 292 73 0826, 
Version A.
    In all three cases, the discrepancies led to a ``one-off'' 
abnormal evolution of gas generator (NG) rating during engine 
starting. In one of these cases, this resulted in an uncommanded in-
flight shutdown, during a cruising phase at 8,000 feet.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    We reviewed Turbomeca MSB No. A292 73 0834, Version B, dated 
February 8, 2011, and SB No. 292 73 0826, Version B, dated February 4, 
2011. This service information describes procedures for inspecting for 
proper ejector installation.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of France, 
and is approved for operation in the United States. Pursuant to our 
bilateral agreement with France, EASA has notified us of the unsafe 
condition described in the MCAI and service information referenced 
above. We are issuing this AD because we evaluated all information 
provided by EASA and determined the unsafe condition exists and is 
likely to exist or develop on other products of the same type design. 
This AD requires inspecting the fuel ejector in the body of the fuel 
ejector assembly for proper installation by checking that the circlip 
is properly seated in its groove, for all affected engines. This AD 
requires the same actions and compliance times as emergency AD 2011-05-
51, after receipt of the emergency AD, and expands the AD applicability 
by including helicopters having one or two affected engines and 
experiencing no starting difficulties.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because of 
the high risk of uncommanded engine in-flight shutdown of one or both 
engines in a two-engine helicopter and an emergency autorotation 
landing or accident.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2011-0141; Directorate 
Identifier 2011-NE-06-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this 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 
with FAA personnel concerning this AD. Using the search function of the 
Web site, anyone can find and read the comments in any of our dockets, 
including, if provided, the name of the individual who sent the comment 
(or signed the comment on behalf of an association, business, labor 
union, etc.). You may review the DOT's complete Privacy Act Statement 
in the Federal Register published on April 11, 2000 (65 FR 19477-78).

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 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 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.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2011-05-08 Turbomeca: Amendment 39-16617; Docket No. FAA-2011-0141; 
Directorate Identifier 2011-NE-06-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective March 9, 
2011.

Affected ADs

    (b) This AD supersedes emergency AD 2011-05-51, issued on 
February 15, 2011.

Applicability

    (c) This AD applies to Turbomeca Arriel 1E2, 1S, and 1S1 
turboshaft engines that have incorporated Turbomeca Service Bulletin 
(SB) No. 292 73 0826, Version A, dated October 13, 2009, or 
incorporated Turbomeca Internal Consign No. 298468. These engines 
are installed on, but not limited to, Eurocopter Deutschland MBB 
BK117-C2 and BK117-C1, and Sikorsky S-76A series and S-76C series, 
helicopters.

Reason

    (d) This AD was prompted by three reports of incorrectly 
assembled low-pressure fuel system ejectors; with one of them 
resulting in an uncommanded engine in-flight shutdown. We are 
issuing this AD to prevent uncommanded engine in-flight shutdown of 
one or both engines in a two-engine helicopter and an emergency 
autorotation landing or accident.

Actions and Compliance

    (e) Comply with this AD within the compliance times specified, 
unless already done.

Fuel Ejector Inspection

    (f) Inspect the fuel ejector in the body of the fuel ejector 
assembly for proper installation by checking that the circlip is 
properly seated in its groove. Use Paragraph 2.B of the Instructions 
to be Incorporated, of Turbomeca Mandatory Service Bulletin (MSB) 
No. A292 73 0834, Version B, dated February 8, 2011 to do the 
inspection. Inspect at the following compliance times:
    (1) For helicopters having at least one of the two affected 
engines experiencing starting difficulties, inspect within 5 flight 
hours (FH) after receipt of emergency AD 2011-05-51 or after the 
effective date of this AD, whichever occurs first.
    (2) For helicopters having only one affected engine, and 
experiencing starting difficulties in that engine, inspect within 20 
FH after receipt of emergency AD 2011-05-51 or after the effective 
date of this AD, whichever occurs first.
    (3) For helicopters having one or two affected engines and 
experiencing no starting difficulties, inspect within 100 FH after 
the effective date of this AD.

Inspection Results

    (g) If you find a fuel ejector improperly installed in the body 
of the fuel ejector assembly, replace the fuel ejector assembly 
before further flight with a serviceable fuel ejector assembly.

Definition

    (h) For the purpose of this AD, starting difficulties occur when 
N1 stagnation or variations are encountered. During starting, N1 
rise shall be continuous and linear up to ground idle.

Credit for Actions Accomplished in Accordance With Previous Service 
Information

    (i) Inspections and replacements done using Turbomeca MSB No. 
A292 73 0834, Version A, dated February 4, 2011, or Turbomeca SB No. 
292 73 0826, Version B, dated February 4, 2011, before the effective 
date of this AD, satisfy the requirements of this AD.

Alternative Methods of Compliance (AMOCs)

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