The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2015–3883; Directorate Identifier 2014–SW–029–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Helicopters Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332L2 and EC225LP helicopters. This proposed AD would require installing a cut-out for the left-hand (LH) and right-hand (RH) rail support junction profiles and inspecting splices, frame 5295, and related equipment for a crack. This proposed AD is prompted by reports of cracks on frame 5295 and on splices installed to prevent those cracks. The proposed actions are intended to detect a crack in frame 5295, which could lead to loss of the helicopter frame’s structural integrity and consequently, loss of helicopter control. DATES: We must receive comments on this proposed AD by March 7, 2016. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Docket: Go to http://www.regulations.gov.

Discussion EASA, which is the Technical Agent for the Member States of the European Union, issued AD No. 2014–0098–E, dated April 25, 2014, to correct an unsafe condition for AS332L2 and EC225LP helicopters. EASA AD No. 2014–0098–E applies to helicopters with a frame 5295 that have been reinforced by installing aluminium splices on the RH and LH fuselage external skins. EASA advises of a report of a crack detected on the reinforced frame during a scheduled inspection of a helicopter. According to EASA, the crack initiated on a splice in an area hidden by the overlapping junction profile of the cabin sliding door rail support, and then spread to the frame. EASA states that a crack in frame 5295, if not detected and corrected, could lead to loss of structural integrity of the helicopter frame and subsequent loss of control of the helicopter. To address this condition, EASA issued AD No. 2014–0098–E to require repetitive inspections of the splices for a crack, as well as cutting out the rail support junction profiles to provide a convenient access to identify cracks in a splice. FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information Under 1 CFR Part 51 We reviewed Airbus Helicopters Alert Service Bulletin (ASB) No. EC225– 05A038 for Model EC225LP helicopters and ASB No. AS332–05.00.97 for Model E:\FR\FM\05JAP1.SGM 05JAP1 192 Federal Register / Vol. 81, No. 2 / Tuesday, January 5, 2016 / Proposed Rules AS332L2 helicopters. The ASBs, both Revision 0 and both dated April 15, 2014, report cracks were found in the splice and frame 5295 on a Model AS332L2 helicopter during a major inspection. The splice had been added in compliance with Modification 0726517. Had an optional rail support cut-out been accomplished on the aircraft to allow for a visual check of the splice for frame 5295, it would have revealed the crack in the splice, prompting its repair and consequently limiting the damage to frame 5295. As a result, the ASBs call for the rail support cut-out on the RH and LH side of the frame as well as periodic visual inspections of frame 5295 and related equipment. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. We reviewed Airbus Service Bulletin (SB) No. 53–003, Revision No. 4, for Model EC225LP helicopters and SB No. 53.01.52, Revision 5, for Model AS332L2 helicopters, both dated July 23, 2010. The SBs specify procedures to reinforce frame 5295 by installing a new titanium plate underneath the fitting and a new widened aluminum splice below the upper corner of the door. We also reviewed Airbus Helicopters Service Bulletin No. 05–019, Revision 4, dated September 22, 2014, for Model EC225LP helicopters, which proposes that you cut out the junction profiles to perform periodic visual inspections. asabaliauskas on DSK5VPTVN1PROD with PROPOSALS Proposed AD Requirements This proposed AD would require the following before a splice reaches 1,700 hours time-in-service (TIS), within 50 hours TIS, or before the helicopter reaches 11,950 hours TIS, whichever occurs later: • Installing the rail support cut-out and identifying the right-hand and lefthand junction profile. • Inspecting each splice for a crack, and repairing or replacing the splice if there is a crack. This proposed AD would then require, at intervals not to exceed 110 hours TIS, inspecting each splice for a crack, and repairing or replacing the splice if there is a crack. Differences Between This Proposed AD and the EASA AD The EASA AD requires contacting Airbus Helicopters if there is a crack in the affected parts. This proposed AD would make no such requirement. 18:34 Jan 04, 2016 Jkt 238001 Costs of Compliance We estimate that this proposed AD would affect 4 helicopters of U.S. Registry and that labor costs average $85 a work-hour. Based on these estimates, we expect the following costs: Installing the cut-outs on frame 5295 would require 40 work hours for a labor cost of $3,400. Parts would cost $5,000 for total cost per helicopter of $8,400 and $33,600 for the U.S. fleet. Inspecting helicopter frame 5295 would require 2 work-hours for a labor cost of $170 per helicopter. No parts would be needed for a total U.S. fleet cost of $680 per inspection cycle. Authority for This Rulemaking Other Related Service Information VerDate Sep<11>2014 The EASA AD sets various timelines for the repair or replacement of affected parts if a crack exists. This proposed AD would require the repair or replacement of affected parts before further flight if a crack exists. 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, 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); PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; and 4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION: On December 7, 2015, the Department announced its intention to explore the feasibility of conducting a reg neg to: • Ensure that the same in-flight entertainment (IFE) available to all passengers is accessible to passengers with disabilities; • Provide individuals dependent on in-flight medical oxygen greater access to air travel consistent with Federal safety and security requirements; • Determine the appropriate definition of a service animal; • Establish safeguards to reduce the likelihood that passengers wishing to travel with their pets will be able to falsely claim that their pets are service animals; • Address the feasibility of accessible lavatories on new single aisle aircraft; • Address whether premium economy is a different class of service from standard economy as airlines are required to provide seating accommodations to passengers with disabilities within the same class of service; and • Require airlines to report annually to the Department the number of requests for disability assistance they receive and the time period within which wheelchair assistance is provided to passengers with disabilities. The Department requested that all comments be submitted no later than January 6, 2016. On December 21, 2015, the Department received a letter from 11 disability advocacy organizations representing diverse interests expressing their concern that the designated comment period does not allow enough time for stakeholders to fully consider the impact of engaging in a negotiated rulemaking on these issues of critical concern to people with disabilities. The disability advocacy organizations noted that as a result of the holidays, the 30day comment period is effectively reduced by nearly two weeks. They noted that the notice and comment process would be more effective if all stakeholders had sufficient time to consider and comment on the efficacy of conducting a negotiated rulemaking on each of the proposed issues. We agree that an extension of the comment period is appropriate given the effective shortening of the comment period by observance of the holidays. We believe that a 15-day extension to E:\FR\FM\05JAP1.SGM 05JAP1

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Helicopters Model AS332L2 and EC225LP helicopters. This 
proposed AD would require installing a cut-out for the left-hand (LH) 
and right-hand (RH) rail support junction profiles and inspecting 
splices, frame 5295, and related equipment for a crack. This proposed 
AD is prompted by reports of cracks on frame 5295 and on splices 
installed to prevent those cracks. The proposed actions are intended to 
detect a crack in frame 5295, which could lead to loss of the 
helicopter frame's structural integrity and consequently, loss of 
helicopter control.

DATES: We must receive comments on this proposed AD by March 7, 2016.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Docket: Go to http://www.regulations.gov. Follow the online instructions for sending your 
comments electronically.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, issued AD No. 2014-0098-E, dated April 25, 2014, to 
correct an unsafe condition for AS332L2 and EC225LP helicopters. EASA 
AD No. 2014-0098-E applies to helicopters with a frame 5295 that have 
been reinforced by installing aluminium splices on the RH and LH 
fuselage external skins. EASA advises of a report of a crack detected 
on the reinforced frame during a scheduled inspection of a helicopter. 
According to EASA, the crack initiated on a splice in an area hidden by 
the overlapping junction profile of the cabin sliding door rail 
support, and then spread to the frame.
    EASA states that a crack in frame 5295, if not detected and 
corrected, could lead to loss of structural integrity of the helicopter 
frame and subsequent loss of control of the helicopter. To address this 
condition, EASA issued AD No. 2014-0098-E to require repetitive 
inspections of the splices for a crack, as well as cutting out the rail 
support junction profiles to provide a convenient access to identify 
cracks in a splice.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other products of the same type design.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Helicopters Alert Service Bulletin (ASB) No. 
EC225-05A038 for Model EC225LP helicopters and ASB No. AS332-05.00.97 
for Model

[[Page 192]]

AS332L2 helicopters. The ASBs, both Revision 0 and both dated April 15, 
2014, report cracks were found in the splice and frame 5295 on a Model 
AS332L2 helicopter during a major inspection. The splice had been added 
in compliance with Modification 0726517. Had an optional rail support 
cut-out been accomplished on the aircraft to allow for a visual check 
of the splice for frame 5295, it would have revealed the crack in the 
splice, prompting its repair and consequently limiting the damage to 
frame 5295. As a result, the ASBs call for the rail support cut-out on 
the RH and LH side of the frame as well as periodic visual inspections 
of frame 5295 and related equipment. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section.

Other Related Service Information

    We reviewed Airbus Service Bulletin (SB) No. 53-003, Revision No. 
4, for Model EC225LP helicopters and SB No. 53.01.52, Revision 5, for 
Model AS332L2 helicopters, both dated July 23, 2010. The SBs specify 
procedures to reinforce frame 5295 by installing a new titanium plate 
underneath the fitting and a new widened aluminum splice below the 
upper corner of the door. We also reviewed Airbus Helicopters Service 
Bulletin No. 05-019, Revision 4, dated September 22, 2014, for Model 
EC225LP helicopters, which proposes that you cut out the junction 
profiles to perform periodic visual inspections.

Proposed AD Requirements

    This proposed AD would require the following before a splice 
reaches 1,700 hours time-in-service (TIS), within 50 hours TIS, or 
before the helicopter reaches 11,950 hours TIS, whichever occurs later:
     Installing the rail support cut-out and identifying the 
right-hand and left-hand junction profile.
     Inspecting each splice for a crack, and repairing or 
replacing the splice if there is a crack.
    This proposed AD would then require, at intervals not to exceed 110 
hours TIS, inspecting each splice for a crack, and repairing or 
replacing the splice if there is a crack.

Differences Between This Proposed AD and the EASA AD

    The EASA AD requires contacting Airbus Helicopters if there is a 
crack in the affected parts. This proposed AD would make no such 
requirement.
    The EASA AD sets various timelines for the repair or replacement of 
affected parts if a crack exists. This proposed AD would require the 
repair or replacement of affected parts before further flight if a 
crack exists.

Costs of Compliance

    We estimate that this proposed AD would affect 4 helicopters of 
U.S. Registry and that labor costs average $85 a work-hour. Based on 
these estimates, we expect the following costs:
    Installing the cut-outs on frame 5295 would require 40 work hours 
for a labor cost of $3,400. Parts would cost $5,000 for total cost per 
helicopter of $8,400 and $33,600 for the U.S. fleet.
    Inspecting helicopter frame 5295 would require 2 work-hours for a 
labor cost of $170 per helicopter. No parts would be needed for a total 
U.S. fleet cost of $680 per inspection cycle.

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, 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 to the extent that 
it justifies making a regulatory distinction; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.

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

Airbus Helicopters: Docket No. FAA-2015-3883; Directorate Identifier 
2014-SW-029-AD.

(a) Applicability

    This AD applies to Model AS332L2 and Model EC225LP helicopters 
with an extended aluminum splice installed on frame 5295, 
certificated in any category.

    Note 1 to paragraph (a) of this AD:  Helicopters with 
modification (MOD) 0726517 have an extended aluminum splice 
installed.

(b) Unsafe Condition

    This AD defines the unsafe condition as a crack on helicopter 
frame 5295. This condition could result in structural failure of the 
frame and subsequent loss of control of the helicopter.

(c) Comments Due Date

    We must receive comments by March 7, 2016.

(d) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(e) Required Actions

    (1) Before a splice reaches 1,700 hours time-in-service (TIS), 
within 50 hours TIS, or before the helicopter reaches 11,950 hours 
TIS, whichever occurs later, do the following:
    (i) Install the rail support cut-out and identify the right-hand 
and left-hand junction
