[FR Doc. 2014–16645 Filed 7–15–14; 8:45 am] BILLING CODE 4910–13–P VerDate Mar<15>2010 17:37 Jul 15, 2014 Jkt 232001 14 CFR Part 39 [Docket No. FAA–2014–0448; Directorate Identifier 2013–NM–055–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes); and Airbus Model A310 series airplanes. This proposed AD was prompted by a report of early ruptures on the levers of the nose landing gear (NLG) sequence valve. This proposed AD would require a onetime inspection for damage of the landing gear sequence valve levers and pin shearing indicating areas on the NLG and the main landing gears (MLGs); and depending on findings, replacing the sequence valve and lever, or doing a one-time inspection to detect interference between control rods and sequence valves and corrective actions if necessary. We are proposing this AD to detect and correct interference between a landing gear leg and door, which could result in failure of that landing gear to extend and could damage the airplane and injure occupants. We must receive comments on this proposed AD by September 2, 2014. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

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 2013–0058, dated March 11, 2013 (referred to after E:\FR\FM\16JYP1.SGM 16JYP1 41460 Federal Register / Vol. 79, No. 136 / Wednesday, July 16, 2014 / Proposed Rules this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A300 series airplanes; Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes); and Airbus Model A310 series airplanes. The MCAI states: Operators have reported five cases of early ruptures on levers of the nose landing gear (NLG) sequence valve. Analysis showed that these fatigue ruptures were due to an incorrect adjustment of the mechanical links. As the design of the main landing gear (MLG) sequence valve lever is similar, there is sufficient reason to assume that these parts are similarly affected by fatigue. This condition, if not detected and corrected, could lead to interference between landing gear leg and door and consequent failure of the landing gear to extend, possibly resulting in damage to the aeroplane and injury to occupants. For the reasons described above, this [EASA] AD requires a one-time inspection of the sequence valve control lever [for damage, which could include cracking or deformation], of the adjustment of the control rod between doors and landing gear sequence valve and depending on inspections results, accomplishment of applicable corrective actions. The corrective actions include adjusting the control rod between the door and the sequence valves; adjusting mechanical linkages; and replacing/ installing a serviceable valve and lever. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2014– 0448. Relevant Service Information Airbus has issued Service Bulletins: • A300–32–0464, dated July 17, 2012 (for Model A300 airplanes); • A300–32–6110, dated July 17, 2012 (for Model A300–600 airplanes); and • A310–32–2146, dated July 17, 2012 (for Model A310 airplanes). The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. tkelley on DSK3SPTVN1PROD with PROPOSALS FAA’s Determination and Requirements of This Proposed 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 VerDate Mar<15>2010 17:37 Jul 15, 2014 Jkt 232001 referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. ‘‘Contacting the Manufacturer’’ Paragraph in This Proposed AD Since late 2006, we have included a standard paragraph titled ‘‘Airworthy Product’’ in all MCAI ADs in which the FAA develops an AD based on a foreign authority’s AD. The MCAI or referenced service information in an FAA AD often directs the owner/operator to contact the manufacturer for corrective actions, such as a repair. Briefly, the Airworthy Product paragraph allowed owners/ operators to use corrective actions provided by the manufacturer if those actions were FAA-approved. In addition, the paragraph stated that any actions approved by the State of Design Authority (or its delegated agent) are considered to be FAA-approved. In another NPRM, Directorate Identifier 2012–NM–101–AD (78 FR 78285, December 26, 2013), we proposed to prevent the use of repairs that were not specifically developed to correct the unsafe condition, by requiring that the repair approval provided by the State of Design Authority or its delegated agent specifically refer to the FAA AD. This change was intended to clarify the method of compliance and to provide operators with better visibility of repairs that are specifically developed and approved to correct the unsafe condition. In addition, we proposed to change the phrase ‘‘its delegated agent’’ to include a design approval holder (DAH) with State of Design Authority design organization approval (DOA), as applicable, to refer to a DAH authorized to approve required repairs for the proposed AD. One commenter to the other NPRM, Directorate Identifier 2012–NM–101–AD (78 FR 78285, December 26, 2013), stated the following: ‘‘The proposed wording, being specific to repairs, eliminates the interpretation that Airbus messages are acceptable for approving minor deviations (corrective actions) needed during accomplishment of an AD mandated Airbus service bulletin.’’ This comment has made the FAA aware that some operators have misunderstood or misinterpreted the Airworthy Product paragraph to allow the owner/operator to use messages provided by the manufacturer as approval of deviations during the accomplishment of an AD-mandated action. The Airworthy Product PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 paragraph does not approve messages or other information provided by the manufacturer for deviations to the requirements of the AD-mandated actions. The Airworthy Product paragraph only addresses the requirement to contact the manufacturer for corrective actions for the identified unsafe condition and does not cover deviations from other AD requirements. However, deviations to AD-required actions are addressed in 14 CFR 39.17, and anyone may request the approval for an alternative method of compliance to the AD-required actions using the procedures found in 14 CFR 39.19. To address this misunderstanding and misinterpretation of the Airworthy Product paragraph, we have changed that paragraph and retitled it ‘‘Contacting the Manufacturer.’’ This paragraph now clarifies that for any requirement in this proposed AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the FAA, the European Aviation Safety Agency (EASA), or Airbus’s EASA DOA. The Contacting the Manufacturer paragraph also clarifies that, if approved by the DOA, the approval must include the DOA-authorized signature. The DOA signature indicates that the data and information contained in the document are EASA-approved, which is also FAAapproved. Messages and other information provided by the manufacturer that do not contain the DOA-authorized signature approval are not EASA-approved, unless EASA directly approves the manufacturer’s message or other information. This clarification does not remove flexibility previously afforded by the Airworthy Product paragraph. Consistent with long-standing FAA policy, such flexibility was never intended for required actions. This is also consistent with the recommendation of the Airworthiness Directive Implementation Aviation Rulemaking Committee to increase flexibility in complying with ADs by identifying those actions in manufacturers’ service instructions that are ‘‘Required for Compliance’’ with ADs. We continue to work with manufacturers to implement this recommendation. But once we determine that an action is required, any deviation from the requirement must be approved as an alternative method of compliance. Costs of Compliance We estimate that this proposed AD affects 128 airplanes of U.S. registry. E:\FR\FM\16JYP1.SGM 16JYP1 Federal Register / Vol. 79, No. 136 / Wednesday, July 16, 2014 / Proposed Rules We also estimate that it would take about 4 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $43,520, or $340 per product. In addition, we estimate that any necessary follow-on actions would take up to 9 work-hours and require parts costing up to $42,000, for a cost of $42,765 per product. We have no way of determining the number of aircraft that might need these actions. 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. tkelley on DSK3SPTVN1PROD with PROPOSALS Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation: 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.

Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2013– 0118, dated June 3, 2013, to correct an unsafe condition for Agusta Model A109K2, A109E, A119, and AW119MKII helicopters. EASA advises that during an overhaul of an A119 main transmission, part number (P/N) 109– 0400–05–103, a crack on the Gleason crown, P/N 109–0403–07–103, was found. EASA further states that an investigation by Agusta revealed that the crack originated from the bottom of one of the 40 threaded holes in the Gleason crown, and that this partnumbered Gleason crown is also installed on Model A109 helicopters. EASA states that this condition, if not corrected, could cause damage to or loss of the main rotor drive and loss of control of the helicopter. To correct this unsafe condition, EASA AD No. 2013– 0118 requires repetitive magnetic particle inspections of the Gleason crown and, if there is a crack, replacing the Gleason crown with a different partnumbered Gleason crown. EASA AD No. 2013–0118 also prohibits installing a Gleason crown, P/N 109–0403–07– 103, or a Gleason crown assembly, P/N 109–0401–27–101 or P/N 109–0401–27– 109, on any helicopter, as Gleason crown, P/N 109–0403–07–103, is a component of these assemblies. Relevant Service Information We reviewed Agusta Bollettino Tecnico (BT) No. 109EP–128 for Model A109E helicopters, Agusta BT No. 109K–57 for Model A109K2 helicopters, and Agusta BT No. 119–058 for Model E:\FR\FM\16JYP1.SGM 16JYP1

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A300 series airplanes; Airbus Model A300 B4-600, B4-600R, 
and F4-600R series airplanes, and Model A300 C4-605R Variant F 
airplanes (collectively called Model A300-600 series airplanes); and 
Airbus Model A310 series airplanes. This proposed AD was prompted by a 
report of early ruptures on the levers of the nose landing gear (NLG) 
sequence valve. This proposed AD would require a one-time inspection 
for damage of the landing gear sequence valve levers and pin shearing 
indicating areas on the NLG and the main landing gears (MLGs); and 
depending on findings, replacing the sequence valve and lever, or doing 
a one-time inspection to detect interference between control rods and 
sequence valves and corrective actions if necessary. We are proposing 
this AD to detect and correct interference between a landing gear leg 
and door, which could result in failure of that landing gear to extend 
and could damage the airplane and injure occupants.

DATES: We must receive comments on this proposed AD by September 2, 
2014.

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 2013-0058, dated March 11, 2013 (referred to 
after

[[Page 41460]]

this as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition for all Airbus Model A300 
series airplanes; Airbus Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes); and Airbus Model A310 series 
airplanes. The MCAI states:

    Operators have reported five cases of early ruptures on levers 
of the nose landing gear (NLG) sequence valve.
    Analysis showed that these fatigue ruptures were due to an 
incorrect adjustment of the mechanical links. As the design of the 
main landing gear (MLG) sequence valve lever is similar, there is 
sufficient reason to assume that these parts are similarly affected 
by fatigue.
    This condition, if not detected and corrected, could lead to 
interference between landing gear leg and door and consequent 
failure of the landing gear to extend, possibly resulting in damage 
to the aeroplane and injury to occupants.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of the sequence valve control lever [for damage, 
which could include cracking or deformation], of the adjustment of 
the control rod between doors and landing gear sequence valve and 
depending on inspections results, accomplishment of applicable 
corrective actions.

The corrective actions include adjusting the control rod between the 
door and the sequence valves; adjusting mechanical linkages; and 
replacing/installing a serviceable valve and lever. You may examine the 
MCAI in the AD docket on the Internet at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2014-0448.

Relevant Service Information

    Airbus has issued Service Bulletins:
     A300-32-0464, dated July 17, 2012 (for Model A300 
airplanes);
     A300-32-6110, dated July 17, 2012 (for Model A300-600 
airplanes); and
     A310-32-2146, dated July 17, 2012 (for Model A310 
airplanes).

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 Proposed 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 proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

``Contacting the Manufacturer'' Paragraph in This Proposed AD

    Since late 2006, we have included a standard paragraph titled 
``Airworthy Product'' in all MCAI ADs in which the FAA develops an AD 
based on a foreign authority's AD.
    The MCAI or referenced service information in an FAA AD often 
directs the owner/operator to contact the manufacturer for corrective 
actions, such as a repair. Briefly, the Airworthy Product paragraph 
allowed owners/operators to use corrective actions provided by the 
manufacturer if those actions were FAA-approved. In addition, the 
paragraph stated that any actions approved by the State of Design 
Authority (or its delegated agent) are considered to be FAA-approved.
    In another NPRM, Directorate Identifier 2012-NM-101-AD (78 FR 
78285, December 26, 2013), we proposed to prevent the use of repairs 
that were not specifically developed to correct the unsafe condition, 
by requiring that the repair approval provided by the State of Design 
Authority or its delegated agent specifically refer to the FAA AD. This 
change was intended to clarify the method of compliance and to provide 
operators with better visibility of repairs that are specifically 
developed and approved to correct the unsafe condition. In addition, we 
proposed to change the phrase ``its delegated agent'' to include a 
design approval holder (DAH) with State of Design Authority design 
organization approval (DOA), as applicable, to refer to a DAH 
authorized to approve required repairs for the proposed AD.
    One commenter to the other NPRM, Directorate Identifier 2012-NM-
101-AD (78 FR 78285, December 26, 2013), stated the following: ``The 
proposed wording, being specific to repairs, eliminates the 
interpretation that Airbus messages are acceptable for approving minor 
deviations (corrective actions) needed during accomplishment of an AD 
mandated Airbus service bulletin.''
    This comment has made the FAA aware that some operators have 
misunderstood or misinterpreted the Airworthy Product paragraph to 
allow the owner/operator to use messages provided by the manufacturer 
as approval of deviations during the accomplishment of an AD-mandated 
action. The Airworthy Product paragraph does not approve messages or 
other information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
the approval for an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed that paragraph and 
retitled it ``Contacting the Manufacturer.'' This paragraph now 
clarifies that for any requirement in this proposed AD to obtain 
corrective actions from a manufacturer, the action must be accomplished 
using a method approved by the FAA, the European Aviation Safety Agency 
(EASA), or Airbus's EASA DOA.
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DOA, the approval must include the DOA-authorized 
signature. The DOA signature indicates that the data and information 
contained in the document are EASA-approved, which is also FAA-
approved. Messages and other information provided by the manufacturer 
that do not contain the DOA-authorized signature approval are not EASA-
approved, unless EASA directly approves the manufacturer's message or 
other information.
    This clarification does not remove flexibility previously afforded 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the Airworthiness 
Directive Implementation Aviation Rulemaking Committee to increase 
flexibility in complying with ADs by identifying those actions in 
manufacturers' service instructions that are ``Required for 
Compliance'' with ADs. We continue to work with manufacturers to 
implement this recommendation. But once we determine that an action is 
required, any deviation from the requirement must be approved as an 
alternative method of compliance.

Costs of Compliance

    We estimate that this proposed AD affects 128 airplanes of U.S. 
registry.

[[Page 41461]]

    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $43,520, or $340 
per product.
    In addition, we estimate that any necessary follow-on actions would 
take up to 9 work-hours and require parts costing up to $42,000, for a 
cost of $42,765 per product. We have no way of determining the number 
of aircraft that might need these actions.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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.
