Download as PDF 48286 Federal Register / Vol. 78, No. 153 / Thursday, August 8, 2013 / Rules and Regulations mstockstill on DSK4VPTVN1PROD with RULES period begins on July 1, and ends on June 30. In an interim rule published in the Federal Register on April 29, 2013, and effective on April 30, 2013 (78 FR 24981, Doc. No. AMS–FV–13–0010, FV13–946–1 IR), § 946.248 was amended by decreasing the assessment rate established for Washington potatoes for the 2013–2014 fiscal year and all subsequent fiscal periods from $0.003 to $0.0025 per hundredweight of potatoes handled. The decrease in the per hundredweight assessment rate allows the Committee to reduce its financial reserve while still providing adequate funding to meet program expenses. Final Regulatory Flexibility Analysis Pursuant to requirements set forth in the Regulatory Flexibility Act (RFA) (5 U.S.C. 601–612), the Agricultural Marketing Service (AMS) has considered the economic impact of this rule on small entities. Accordingly, AMS has prepared this final regulatory flexibility analysis. The purpose of the RFA is to fit regulatory actions to the scale of businesses subject to such actions in order that small businesses will not be unduly or disproportionately burdened. Marketing orders issued pursuant to the Act, and the rules issued thereunder, are unique in that they are brought about through group action of essentially small entities acting on their own behalf. There are 43 handlers of Washington potatoes subject to regulation under the order and approximately 267 producers in the regulated production area. Small agricultural service firms are defined by the Small Business Administration as those having annual receipts of less than $7,000,000, and small agricultural producers are defined as those having annual receipts of less than $750,000. (13 CFR 121.201) During the 2011–2012 marketing year, the Committee reports that 11,018,670 hundredweight of Washington potatoes were shipped into the fresh market. Based on average f.o.b. prices estimated by the USDA’s Economic Research Service and Committee data on individual handler shipments, the Committee estimates that 42, or approximately 98 percent, of the handlers had annual receipts of less than $7,000,000. In addition, based on information provided by the National Agricultural Statistics Service, the average producer price for Washington potatoes for 2011 was $7.90 per hundredweight. The average gross annual revenue for the 267 Washington potato producers is therefore calculated to be approximately VerDate Mar<15>2010 16:04 Aug 07, 2013 Jkt 229001 $326,021. In view of the foregoing, the majority of Washington potato producers and handlers may be classified as small entities. This rule continues in effect the action that decreased the assessment rate established for the Committee and collected from handlers for the 2013– 2014 fiscal year and all subsequent fiscal periods from $0.003 to $0.0025 per hundredweight of potatoes. The Committee also unanimously recommended 2013–2014 expenditures of $37,400. This action will allow the Committee to reduce its financial reserve while still providing adequate funding to meet program expenses. The quantity of assessable potatoes for the 2013–2014 fiscal period is estimated at 10,000,000 hundredweight. Thus, the $0.0025 rate should provide $25,000 in assessment income. Income derived from handler assessments, along with interest income and funds from the Committee’s authorized reserve, will be adequate to cover budgeted expenses. This rule continues in effect the action that decreased the assessment obligation imposed on handlers. Assessments are applied uniformly on all handlers, and some of the costs may be passed on to producers. However, decreasing the assessment rate reduces the burden on handlers and may reduce the burden on producers. In addition, the Committee’s meeting was widely publicized throughout the Washington potato industry. All interested persons were invited to attend the meeting and participate in Committee deliberations on all issues. Like all Committee meetings, the January 30, 2013, meeting was a public meeting. All entities, both large and small, were able to express their views on this issue. 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, Vegetable and Specialty Crops Generic Package. 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 action imposes no additional reporting or recordkeeping requirements on either small or large Washington potato 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. PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 USDA has not identified any relevant Federal rules that duplicate, overlap, or conflict with this rule. Comments on the interim rule were required to be received on or before June 28, 2013. No comments were received. Therefore, for 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/#!documentDetail; D=AMS-FV-13-0010-0001. This action also affirms information contained in the interim rule concerning Executive Orders 12866 and 12988, 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 24981, April 29, 2013) will tend to effectuate the declared policy of the Act. List of Subjects in 7 CFR Part 946 Marketing agreements, Potatoes, Reporting and recordkeeping requirements. PART 946—IRISH POTATOES GROWN IN WASHINGTON Accordingly, the interim rule amending 7 CFR part 946, which was published at 78 FR 24981 on April 29, 2013, is adopted as a final rule, without change.

ACTION: Final rule; request for comments. AGENCY: We are adopting a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and SUMMARY: E:\FR\FM\08AUR1.SGM 08AUR1 Federal Register / Vol. 78, No. 153 / Thursday, August 8, 2013 / Rules and Regulations A321 series airplanes. This AD requires an inspection to determine airplane configuration and part numbers of the landing gear control interface unit and main landing gear (MLG) door actuators; and, for affected airplanes, repetitive inspections of the opening sequence of the MLG door actuator, and replacement of the MLG door actuator if necessary. This AD also provides optional terminating action for the repetitive inspections. This AD was prompted by a report of a MLG failing to extend during landing, and a determination that a certain configuration of landing gear control interface unit and actuators may result in masking of centralized fault display system messages that are necessary to mitigate risks associated with failure of MLG extension or downlocking. We are issuing this AD to detect and correct such a configuration, which could prevent the full extension or down-locking of the MLG, possibly resulting in MLG collapse during landing and consequent damage to the airplane and injury to occupants. DATES: This AD becomes effective August 23, 2013. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 23, 2013. We must receive comments on this AD by September 23, 2013. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

SUPPLEMENTARY INFORMATION: establish the configuration and, for those aeroplanes, repetitive inspections of the opening sequence of the MLG door actuator and, depending on findings, replacement of the MLG door actuator. This [EASA] AD also provides optional terminating action by disconnection of the interlink for certain LGCIUs, or in-service modification of the aeroplane by installation of MLG actuator Part Number (P/N) 114122014 through Airbus SB A320–32–1407 (Airbus production mod. 153655). Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Emergency Airworthiness Directive 2013–0132–E, dated June 25, 2013 (referred to after this as the ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Doing an inspection of the door opening sequence of the left-hand and right-hand doors of the MLG of an airplane, as required by paragraph (h) of this AD, is an acceptable alternative method to comply with the requirements of paragraphs (j) and (l) of AD 2011–13–11, Amendment 39–16734 (76 FR 37241, June 27, 2011), for that airplane. You may obtain further information by examining the MCAI in the AD docket. Some operators reported slow operation of the main landing gear (MLG) door opening/ closing sequence, leading to the generation of Centralized Fault Display System (CFDS) messages/ECAM [electronic centralized aircraft monitor] warnings during the landing gear retraction or extension sequence. Investigations showed that the damping ring and associated retaining ring of the MLG door actuator deteriorate. The resultant debris increases the friction inside the actuator which can be sufficiently high to restrict opening of the MLG door by gravity, during operation of the landing gear alternate (free-fall) extension system. This condition, if not detected and corrected, could prevent the full extension and/or down-locking of the MLG, possibly resulting in MLG collapse during landing and consequent damage to the aeroplane and injury to occupants. To address this potential unsafe condition, EASA issued [EASA] AD 2011–0069 (currently at R1) [http://ad.easa.europa.eu/ blob/easa_ad_2011_0069_R1.pdf/AD_20110069R1_1] [which corresponds to FAA AD 2011–13–11, Amendment 39–16734 (76 FR 37241, June 27, 2011)] to require an amendment of the applicable Airplane Flight Manual (AFM), repetitive checks of specific CFDS messages, and repetitive inspections of the opening sequence of the MLG door actuator and, depending on findings, corrective action. Since that AD [EASA AD 2011–0069R1] was issued, following a recent occurrence with a gear extension problem, additional analyses by Airbus have revealed that the CFDS expected specific messages may be not generated and as a result, repetitive checks of messages are not effective for aeroplanes fitted with landing gear control interface unit (LGCIU) interlink communication ARINC 429 (applied in production through Airbus Modification (mod.) 39303, or in service through Airbus Service Bulletin (SB) A320– 32–1409), in combination with certain LGCIUs and MLG door actuators installed. For the reasons described above, this [EASA] Emergency AD requires identification of the affected aeroplanes to PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 Relevant Service Information Airbus has issued Alert Operators Transmission (AOT) A32N001–13, dated June 24, 2013; and Airbus Service Bulletin A320–32–1407, dated May 14, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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. 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. Since the issuance of FAA AD 2011–13–11, Amendment 39–16734 (76 FR 37241, June 27, 2011), we have received a report of a MLG failing to extend during landing. We have also been notified that a certain configuration of LGCIU and actuators may result in masking of CFDS messages that are necessary to mitigate risks associated with failure of MLG E:\FR\FM\08AUR1.SGM 08AUR1 48288 Federal Register / Vol. 78, No. 153 / Thursday, August 8, 2013 / Rules and Regulations extension or down-locking. This condition could possibly result in MLG collapse during landing and consequent damage to the airplane and injury to occupants. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. 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–2013–0671; Directorate Identifier 2013–NM–124– 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 http:// 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. Costs of Compliance We estimate that this AD affects 851 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Configuration and part number determination. MLG door repetitive inspection 1 work-hour × $85 per hour = $85. 2 work-hours × $85 per hour = $170 per inspection cycle. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in 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. mstockstill on DSK4VPTVN1PROD with RULES 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 that this AD: VerDate Mar<15>2010 16:04 Aug 07, 2013 Jkt 229001 Parts cost Cost on U.S. operators Cost per product $0 $85 ....................................... $72,335. $0 $170 per inspection cycle .... $144,670 per inspection cycle. 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. We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A318, A319, A320, and

[[Page 48287]]

A321 series airplanes. This AD requires an inspection to determine 
airplane configuration and part numbers of the landing gear control 
interface unit and main landing gear (MLG) door actuators; and, for 
affected airplanes, repetitive inspections of the opening sequence of 
the MLG door actuator, and replacement of the MLG door actuator if 
necessary. This AD also provides optional terminating action for the 
repetitive inspections. This AD was prompted by a report of a MLG 
failing to extend during landing, and a determination that a certain 
configuration of landing gear control interface unit and actuators may 
result in masking of centralized fault display system messages that are 
necessary to mitigate risks associated with failure of MLG extension or 
down-locking. We are issuing this AD to detect and correct such a 
configuration, which could prevent the full extension or down-locking 
of the MLG, possibly resulting in MLG collapse during landing and 
consequent damage to the airplane and injury to occupants.

DATES: This AD becomes effective August 23, 2013.

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 
Emergency Airworthiness Directive 2013-0132-E, dated June 25, 2013 
(referred to after this as the ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

Some operators reported slow operation of the main landing gear 
(MLG) door opening/closing sequence, leading to the generation of 
Centralized Fault Display System (CFDS) messages/ECAM [electronic 
centralized aircraft monitor] warnings during the landing gear 
retraction or extension sequence. Investigations showed that the 
damping ring and associated retaining ring of the MLG door actuator 
deteriorate. The resultant debris increases the friction inside the 
actuator which can be sufficiently high to restrict opening of the 
MLG door by gravity, during operation of the landing gear alternate 
(free-fall) extension system.
    This condition, if not detected and corrected, could prevent the 
full extension and/or down-locking of the MLG, possibly resulting in 
MLG collapse during landing and consequent damage to the aeroplane 
and injury to occupants.
    To address this potential unsafe condition, EASA issued [EASA] 
AD 2011-0069 (currently at R1) [http://ad.easa.europa.eu/blob/easa_ad_2011_0069_R1.pdf/AD_2011-0069R1_1] [which corresponds to FAA 
AD 2011-13-11, Amendment 39-16734 (76 FR 37241, June 27, 2011)] to 
require an amendment of the applicable Airplane Flight Manual (AFM), 
repetitive checks of specific CFDS messages, and repetitive 
inspections of the opening sequence of the MLG door actuator and, 
depending on findings, corrective action.
    Since that AD [EASA AD 2011-0069R1] was issued, following a 
recent occurrence with a gear extension problem, additional analyses 
by Airbus have revealed that the CFDS expected specific messages may 
be not generated and as a result, repetitive checks of messages are 
not effective for aeroplanes fitted with landing gear control 
interface unit (LGCIU) interlink communication ARINC 429 (applied in 
production through Airbus Modification (mod.) 39303, or in service 
through Airbus Service Bulletin (SB) A320-32-1409), in combination 
with certain LGCIUs and MLG door actuators installed.
    For the reasons described above, this [EASA] Emergency AD 
requires identification of the affected aeroplanes to establish the 
configuration and, for those aeroplanes, repetitive inspections of 
the opening sequence of the MLG door actuator and, depending on 
findings, replacement of the MLG door actuator.
    This [EASA] AD also provides optional terminating action by 
disconnection of the interlink for certain LGCIUs, or in-service 
modification of the aeroplane by installation of MLG actuator Part 
Number (P/N) 114122014 through Airbus SB A320-32-1407 (Airbus 
production mod. 153655).

    Doing an inspection of the door opening sequence of the left-hand 
and right-hand doors of the MLG of an airplane, as required by 
paragraph (h) of this AD, is an acceptable alternative method to comply 
with the requirements of paragraphs (j) and (l) of AD 2011-13-11, 
Amendment 39-16734 (76 FR 37241, June 27, 2011), for that airplane.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Alert Operators Transmission (AOT) A32N001-13, 
dated June 24, 2013; and Airbus Service Bulletin A320-32-1407, dated 
May 14, 2013. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI.

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.

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. Since the 
issuance of FAA AD 2011-13-11, Amendment 39-16734 (76 FR 37241, June 
27, 2011), we have received a report of a MLG failing to extend during 
landing. We have also been notified that a certain configuration of 
LGCIU and actuators may result in masking of CFDS messages that are 
necessary to mitigate risks associated with failure of MLG

[[Page 48288]]

extension or down-locking. This condition could possibly result in MLG 
collapse during landing and consequent damage to the airplane and 
injury to occupants. Therefore, we determined that notice and 
opportunity for public comment before issuing this AD are impracticable 
and that good cause exists for making this amendment effective in fewer 
than 30 days.

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-2013-0671; Directorate 
Identifier 2013-NM-124-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 http://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.

Costs of Compliance

    We estimate that this AD affects 851 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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 that 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);
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
