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 Examining the AD Docket 14 CFR Part 39 [Docket No. FAA–2018–0761; Product Identifier 2018–NM–088–AD] RIN 2120–AA64 Airworthiness Directives; Airbus SAS Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350–941 airplanes. This proposed AD was prompted by reports that, for multimaterial (hybrid) joints of the passenger door frame fittings, the interfay sealant was not applied between all surfaces of the joint parts. This proposed AD would require modification of the hybrid joints of the passenger doors by applying additional corrosion protection to the hybrid joints of the passenger door frame fittings. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by October 19, 2018. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, 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 PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 for the Member States of the European Union, has issued EASA AD 2018–0108, dated May 15, 2018 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Airbus SAS model A350–941 airplanes. The MCAI states: Due to the misinterpretation of the prevailing requirements for multimaterial (hybrid) joints of the passenger door frame fittings, the interfay sealant, which prevents water ingress, was only applied on the surface in direct contact with the aluminum parts and not between all surfaces of the joint parts. For sealing of multi-material-stacks involving aluminum, application of interfay sealant is necessary between all assembled parts, even between parts made of corrosion resistant material, in order to ensure a double barrier to prevent water ingress in the joint and subsequent potential galvanic corrosion on the aluminum holes. This condition, if not corrected, could lead to failure of the door to perform its intended function, possibly resulting in reduced evacuation capacity from the aeroplane during an emergency and consequent injury to occupants. To address this unsafe condition, Airbus developed production mod 110790 and mod 109554 to improve protection against corrosion, and issued the SB [Airbus Service Bulletin A350–52–P012, Revision 00, dated September 7, 2017] to provide modification instructions for in-service pre-mod aeroplanes. For the reasons described above, this [EASA] AD requires a modification by adding sealant and protective treatment on the affected passenger doors. 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–2018– 0761. Related Service Information Under 1 CFR Part 51 Airbus SAS has issued Service Bulletin A350–52–P012, Revision 00, dated September 7, 2017. This service information describes procedures for modification of the hybrid joints of the left-hand and right-hand sides of the passenger door frame fittings at doors 1, 2, 3 and 4, by applying additional corrosion protection. 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. E:\FR\FM\04SEP1.SGM 04SEP1 Federal Register / Vol. 83, No. 171 / Tuesday, September 4, 2018 / Proposed Rules FAA’s Determination 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 the relevant information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would require accomplishing the actions specified in 44845 the service information described previously. Costs of Compliance We estimate that this proposed AD affects 1 airplane of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Parts cost Cost per product Cost on U.S. operators 60 work-hours × $85 per hour = $5,100 ..................................................................................... $0 $5,100 $5,100 sradovich on DSK3GMQ082PROD with PROPOSALS According to the manufacturer, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all known costs in our cost estimate. 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We determined that this proposed AD would not have federalism implications VerDate Sep<11>2014 16:36 Aug 31, 2018 Jkt 244001 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

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0108, dated May 15, 2018 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Airbus SAS model A350-941 airplanes. The 
MCAI states:

    Due to the misinterpretation of the prevailing requirements for 
multimaterial (hybrid) joints of the passenger door frame fittings, 
the interfay sealant, which prevents water ingress, was only applied 
on the surface in direct contact with the aluminum parts and not 
between all surfaces of the joint parts. For sealing of multi-
material-stacks involving aluminum, application of interfay sealant 
is necessary between all assembled parts, even between parts made of 
corrosion resistant material, in order to ensure a double barrier to 
prevent water ingress in the joint and subsequent potential galvanic 
corrosion on the aluminum holes.
    This condition, if not corrected, could lead to failure of the 
door to perform its intended function, possibly resulting in reduced 
evacuation capacity from the aeroplane during an emergency and 
consequent injury to occupants.
    To address this unsafe condition, Airbus developed production 
mod 110790 and mod 109554 to improve protection against corrosion, 
and issued the SB [Airbus Service Bulletin A350-52-P012, Revision 
00, dated September 7, 2017] to provide modification instructions 
for in-service pre-mod aeroplanes.
    For the reasons described above, this [EASA] AD requires a 
modification by adding sealant and protective treatment on the 
affected passenger doors.

    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-2018-
0761.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued Service Bulletin A350-52-P012, Revision 00, 
dated September 7, 2017. This service information describes procedures 
for modification of the hybrid joints of the left-hand and right-hand 
sides of the passenger door frame fittings at doors 1, 2, 3 and 4, by 
applying additional corrosion protection. 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.

FAA's Determination

    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 the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 1 airplane of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
60 work-hours x $85 per hour = $5,100........................              $0           $5,100           $5,100
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. We do not control warranty coverage for 
affected individuals. As a result, we have included all known costs in 
our cost estimate.

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

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

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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 airworthiness 
directive (AD):

Airbus SAS: Docket No. FAA-2018-0761; Product Identifier 2018-NM-
088-AD.

(a) Comments Due Date

    We must receive comments by October 19, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus SAS Model A350-941 airplanes, 
certificated in any category, as identified in Airbus Service 
Bulletin A350-52-P012, Revision 00, dated September 7, 2017.

(d) Subject

    Air Transport Association (ATA) of America Code 52, Doors.

(e) Reason

    This AD was prompted by reports that, for multimaterial (hybrid) 
joints of the passenger door frame fittings, the interfay sealant 
was not applied between all surfaces of the joint parts. We are 
issuing this AD to prevent water ingress in the hybrid joints and 
subsequent galvanic corrosion of the aluminum holes. This condition, 
if not corrected, could lead to failure of the door, resulting in 
reduced evacuation capacity from the airplane during an emergency 
and consequent injury to occupants.

(f) Compliance

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

(g) Modification of Passenger Door Hybrid Joints

    Within 48 months after the date of issuance of the original 
certificate of airworthiness or the original export certificate of 
airworthiness, whichever occurs earlier: Apply additional corrosion 
protection (e.g., primer/topcoat or corrosion prevention compound) 
to the hybrid joints of the left-hand and right-hand sides of the 
passenger door frame fittings at doors 1, 2, 3 and 4, in accordance 
with the Accomplishment Instructions of Airbus Service Bulletin 
A350-52-P012, Revision 00, dated September 7, 2017.

(h) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Section, Transport Standards Branch, FAA, has the 
authority to approve AMOCs for this

[[Page 44846]]

AD, if requested using the procedures found in 14 CFR 39.19. In 
accordance with 14 CFR 39.19, send your request to your principal 
inspector or local Flight Standards District Office, as appropriate. 
If sending information directly to the International Section, send 
it to the attention of the person identified in paragraph (i)(2) of 
this AD. Information may be emailed to: [email protected]. Before using any approved AMOC, notify your 
appropriate principal inspector, or lacking a principal inspector, 
the manager of the local flight standards district office/
certificate holding district office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or the European Aviation 
Safety Agency (EASA); or Airbus SAS's EASA Design Organization 
Approval (DOA). If approved by the DOA, the approval must include 
the DOA-authorized signature.
    (3) Required for Compliance (RC): If any service information 
contains procedures or tests that are identified as RC, those 
procedures and tests must be done to comply with this AD; any 
procedures or tests that are not identified as RC are recommended. 
Those procedures and tests that are not identified as RC may be 
deviated from using accepted methods in accordance with the 
operator's maintenance or inspection program without obtaining 
approval of an AMOC, provided the procedures and tests identified as 
RC can be done and the airplane can be put back in an airworthy 
condition. Any substitutions or changes to procedures or tests 
identified as RC require approval of an AMOC.
