SUPPLEMENTARY INFORMATION: VerDate Mar<15>2010 14:45 Mar 09, 2011 Jkt 223001 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 2010–0132, dated June 28, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During a recent in-service event the flight crew of a Trent 700 powered A330 aircraft reported a temporary Engine Pressure Ratio (EPR) shortfall on engine 2 during the takeoff phase of the flight. The ENG STALL warning was set. The flight crew followed the standard procedures which included reducing throttle to idle. The engine recovered and provided the demanded thrust level for the remainder of the flight. Data analysis confirmed a temporary fuel flow restriction and subsequent recovery, and indicated that also engine 1 experienced a temporary fuel flow restriction shortly after the initial event on engine 2, again followed by a full recovery. The engine 1 EPR shortfall was insufficient to trigger any associated warning and was only noted through analysis of the flight data. No flight crew action was necessary to recover normal performance on this engine. The remainder of the flight was uneventful. Based on previous industry-wide experience, the investigation of the event has focused on the possibility for ice to temporarily restrict the fuel flow. While no direct fuel system fault has been identified, the operation of the water scavenge system at Rib 3 cannot be excluded as being a contributory factor. Testing and analysis are continuing to identify the root cause of the event. The scenario of ice being shed and causing a temporary blockage in the engine fuel system may lead to a temporary fuel flow restriction to the engine. This may result in a possible engine surge or stall condition, and in the engine not being able to provide the commanded thrust. Therefore, as a precautionary measure to reduce the possibility of ingesting ice into the engine fuel feed system, EASA EAD 2010– 0042–E [which corresponds to FAA AD 2010–08–08] required to: —Deactivate the automatic Standby Fuel Pump Scavenge System, which operates during Taxi and Take-off by removing relays Functional Item Numbers (FIN) 80QA1 and 80QA2 (this will not affect normal standby pump operation) for aeroplanes identified in the applicability section of this AD and on which this deactivation has not been performed in production through the modification 200801, and —Prohibit the dispatch with * * * [a] MAIN Fuel Pump inoperative on all aeroplanes identified in the applicability section of this AD. This AD * * * is issued to extend the applicability to the newly certified model A330–243F. This AD also requires revising the Limitations section of the airplane flight PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 manual to advise the flight crew of the dispatch prohibition. You may obtain further information by examining the MCAI in the AD docket. FAA’s Determination and Requirements of This AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future. Differences Between the AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a Note within the AD. FAA’s Determination of the Effective Date Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. 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–2011–0156; Directorate Identifier 2010–NM–231– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, E:\FR\FM\10MRR1.SGM 10MRR1 Federal Register / Vol. 76, No. 47 / Thursday, March 10, 2011 / Rules and Regulations 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 we receive about this AD. 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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. jdjones on DSK8KYBLC1PROD with RULES Regulatory Findings § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: ■ 2011–06–04 Airbus: Amendment 39–16628. Docket No. FAA–2011–0156; Directorate Identifier 2010–NM–231–AD.

AGENCY: We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires you to incorporate operating limitations of maximum operating altitude of 37,000 feet into Section 2, Limitations, of the airplane flight manual (AFM). This AD requires you to incorporate operating limitations of maximum operating altitude of 30,000 feet into Section 2, Limitations, of the AFM. This AD was prompted by several incidents of engine surge. We are issuing this AD to prevent hard carbon buildup on the static vane, which could result in engine surges. Engine surges may result in a necessary reduction in thrust and decreased power for the affected engine. In some cases, this could result in flight and landing under single-engine conditions. It is also possible this could affect both engines at the same time, requiring dual-engine shutdown. DATES: This AD is effective March 21, 2011.

SUPPLEMENTARY INFORMATION: Discussion On November 17, 2008, we issued AD 2008–24–07, amendment 39–15747 (73 FR 70866, November 24, 2008), for certain Eclipse Aviation Corporation (Eclipse) Model EA500 airplanes equipped with a Pratt and Whitney Canada, Corp. (PWC) PW610F–A engine. That AD requires you to incorporate operating limitations into Section 2, Limitations, of the airplane flight manual (AFM). That AD resulted from several incidents of engine surge. We issued that AD to prevent hard carbon buildup on the static vane, which could result in engine surges. Engine surges may result in a necessary reduction in thrust and decreased power for the affected engine. In some cases, this could result in flight and landing under single-engine conditions. flight shutdown of the affected engine. This could occur in flight and require landing under single-engine conditions. It is also possible that this could affect both engines at the same time, requiring dual-engine shutdown. FAA’s Determination We are issuing 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. AD Requirements This AD requires you to incorporate operating limitations of maximum operating altitude of 30,000 feet into Section 2, Limitations, of the AFM. Interim Action We consider this AD interim action. The PWC PW610F–A engine is certificated in Canada and is certificated as a foreign type-validated engine under FAA TCDS E00074EN. The FAA understands that Transport Canada (the airworthiness authority for Canada) and PWC are considering potential actions to address the engine aspects of this condition. In the meantime, the FAA is issuing this AD on the Eclipse Model EA500 to address the immediate unsafe condition and to mandate the altitude limitation. Actions Since AD was Issued FAA’s Justification and 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 a reduction of available thrust or an in-flight shutdown of the affected engine might occur. This could occur in flight and require landing under single-engine conditions. It is also possible that this could affect both engines at the same time, requiring dual-engine shutdown. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Since we issued AD 2008–24–07, the unsafe condition of engine surges due to hard carbon build up blocking the static vanes has continued to occur at 37,000 feet altitude and lower. Six known events have occurred, five of which were at or below 37,000 feet altitude and four of which were in a two-week period. Operating effects may include a reduction of available thrust or an in- Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section.

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) originated 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:

    During a recent in-service event the flight crew of a Trent 700 
powered A330 aircraft

[[Page 13076]]

reported a temporary Engine Pressure Ratio (EPR) shortfall on engine 
2 during the take-off phase of the flight. * * *
    Data analysis confirmed a temporary fuel flow restriction and 
subsequent recovery, and indicated that also engine 1 experienced a 
temporary fuel flow restriction shortly after the initial event on 
engine 2 * * *.
    Based on previous industry-wide experience, the investigation of 
the event has focused on the possibility for ice to temporarily 
restrict the fuel flow. * * *
    * * * The scenario of ice being shed and causing a temporary 
blockage in the engine fuel system may lead to a temporary fuel flow 
restriction to the engine. This may result in a possible engine 
surge or stall condition, and in the engine not being able to 
provide the commanded thrust.
* * * * *
    This AD requires actions that are intended to address the unsafe

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 2010-0132, dated June 28, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During a recent in-service event the flight crew of a Trent 700 
powered A330 aircraft reported a temporary Engine Pressure Ratio 
(EPR) shortfall on engine 2 during the take-off phase of the flight. 
The ENG STALL warning was set. The flight crew followed the standard 
procedures which included reducing throttle to idle. The engine 
recovered and provided the demanded thrust level for the remainder 
of the flight.
    Data analysis confirmed a temporary fuel flow restriction and 
subsequent recovery, and indicated that also engine 1 experienced a 
temporary fuel flow restriction shortly after the initial event on 
engine 2, again followed by a full recovery. The engine 1 EPR 
shortfall was insufficient to trigger any associated warning and was 
only noted through analysis of the flight data. No flight crew 
action was necessary to recover normal performance on this engine. 
The remainder of the flight was uneventful.
    Based on previous industry-wide experience, the investigation of 
the event has focused on the possibility for ice to temporarily 
restrict the fuel flow. While no direct fuel system fault has been 
identified, the operation of the water scavenge system at Rib 3 
cannot be excluded as being a contributory factor.
    Testing and analysis are continuing to identify the root cause 
of the event. The scenario of ice being shed and causing a temporary 
blockage in the engine fuel system may lead to a temporary fuel flow 
restriction to the engine. This may result in a possible engine 
surge or stall condition, and in the engine not being able to 
provide the commanded thrust.
    Therefore, as a precautionary measure to reduce the possibility 
of ingesting ice into the engine fuel feed system, EASA EAD 2010-
0042-E [which corresponds to FAA AD 2010-08-08] required to:

--Deactivate the automatic Standby Fuel Pump Scavenge System, which 
operates during Taxi and Take-off by removing relays Functional Item 
Numbers (FIN) 80QA1 and 80QA2 (this will not affect normal standby 
pump operation) for aeroplanes identified in the applicability 
section of this AD and on which this deactivation has not been 
performed in production through the modification 200801, and
--Prohibit the dispatch with * * * [a] MAIN Fuel Pump inoperative on 
all aeroplanes identified in the applicability section of this AD.

    This AD * * * is issued to extend the applicability to the newly 
certified model A330-243F.

    This AD also requires revising the Limitations section of the 
airplane flight manual to advise the flight crew of the dispatch 
prohibition. You may obtain further information by examining the MCAI 
in the AD docket.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

Differences Between the AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the AD.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

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-2011-0156; Directorate 
Identifier 2010-NM-231-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic,

[[Page 13077]]

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 we 
receive about this AD.

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.
