SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0244, dated November 13, 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: During inspection on an aeroplane in final assembly line, un-torqued nuts on slat and flap shaft junctions have been reported. This condition, if not detected and corrected, in case of two or more nuts missing or incorrectly torqued on a shaft junction and concurrent failure of a different shaft, could lead to uncommanded slat or flap movement, possibly resulting in loss of control of the aeroplane. To address this potential unsafe condition, Airbus published the SB [Service Bulletin A350–27–P022] to provide applicable instructions. For the reasons describe above, this [EASA] AD requires a one-time detailed inspection (DET) of each affected junction, and, depending on findings, accomplishment of applicable corrective action(s). Corrective actions include ensuring correct torque on all nuts and bolts, applying torque red line markings on affected nuts, and replacing any missing bolt. You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 and locating Docket No. FAA–2019– 0122. Related Service Information Under 1 CFR Part 51 Airbus has issued Service Bulletin A350–27–P022, Revision 00, dated June 6, 2018. This service information describes procedures for a one-time inspection of each junction of flap torque-shaft 2 and slat torque-shafts 2 and 4 for discrepancies (including missing torque marking on any nut, any untorqued nut, or any missing bolt). The service information also describes procedures for torqueing any affected nuts and bolts, applying torque red line markings on affected nuts, and replacing any missing bolts. 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 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. Requirements of This AD This AD requires accomplishing the actions specified in the service information described previously. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because two or more missing or incorrectly torqued nuts on a junction of certain slat and flap shafts, concurrent failure of an alternate flap shaft, and consequent uncommanded slat or flap movement, could result in loss of control of the airplane. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reasons stated above, we find that good cause exists for making this amendment effective in less than 30 days.

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 based on those comments. We will post all comments we receive, without change, to https:// 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–2019–0122; 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 1 airplane of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 12 work-hours × $85 per hour = $1,020 ..................................................................................... $0 $1,020 $1,020 We estimate the following costs to do any necessary on-condition actions that would be required based on the results of any required actions. We have no way of determining the number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 3 work-hours × $85 per hour = $255 ...................................................................................................................... $1,000 $1,255 According to the manufacturer, some or all of the costs of this 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 AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. VerDate Sep<11>2014 16:22 Mar 21, 2019 Jkt 247001 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 and associated appliances to the Director of the System Oversight Division. 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.

SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0244, dated November 13, 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:

    During inspection on an aeroplane in final assembly line, un-
torqued nuts on slat and flap shaft junctions have been reported.
    This condition, if not detected and corrected, in case of two or 
more nuts missing or incorrectly torqued on a shaft junction and 
concurrent failure of a different shaft, could lead to uncommanded 
slat or flap movement, possibly resulting in loss of control of the 
aeroplane.
    To address this potential unsafe condition, Airbus published the 
SB [Service Bulletin A350-27-P022] to provide applicable 
instructions.
    For the reasons describe above, this [EASA] AD requires a one-
time detailed inspection (DET) of each affected junction, and, 
depending on findings, accomplishment of applicable corrective 
action(s).

    Corrective actions include ensuring correct torque on all nuts and 
bolts, applying torque red line markings on affected nuts, and 
replacing any missing bolt. 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-2019-0122.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A350-27-P022, Revision 00, dated 
June 6, 2018. This service information describes procedures for a one-
time inspection of each junction of flap torque-shaft 2 and slat 
torque-shafts 2 and 4 for discrepancies (including missing torque 
marking on any nut, any untorqued nut, or any missing bolt). The 
service information also describes procedures for torqueing any 
affected nuts and bolts, applying torque red line markings on affected 
nuts, and replacing any missing bolts.
    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 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.

Requirements of This AD

    This AD requires accomplishing the actions specified in the service 
information described previously.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because two or more missing or incorrectly torqued nuts on a junction 
of certain slat and flap shafts, concurrent failure of an alternate 
flap shaft, and consequent uncommanded slat or flap movement, could 
result in loss of control of the airplane. Therefore, we find good 
cause that notice and opportunity for prior public comment are 
impracticable. In addition, for the reasons stated above, we find that 
good cause exists for making this amendment effective in less than 30 
days.

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

    We estimate the following costs to do any necessary on-condition 
actions that would be required based on the results of any required 
actions. We have no way of determining the number of aircraft that 
might need these on-condition actions:

    According to the manufacturer, some or all of the costs of this 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 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 and 
associated appliances to the Director of the System Oversight Division.

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.

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

2019-05-10 Airbus SAS: Amendment 39-19592; Docket No. FAA-2019-0122; 
Product Identifier 2018-NM-164-AD.

(a) Effective Date

    This AD becomes effective April 8, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus SAS Model A350-941 airplanes, 
certificated in any category, manufacturer serial numbers as 
identified in Airbus Service Bulletin A350-27-P022, Revision 00, 
dated June 6, 2018.

[[Page 10670]]

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Reason

    This AD was prompted by a report of un-torqued nuts on certain 
slat and flap shaft junctions of the wings. We are issuing this AD 
to address two or more missing or incorrectly torqued nuts on a 
junction of certain slat and flap shafts, concurrent failure of an 
alternate flap shaft, and consequent uncommanded slat or flap 
movement, which could result in loss of control of the airplane.

(f) Compliance

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

(g) One-Time Inspection and Corrective Action

    Within 3 months after the effective date of this AD: Do a one-
time detailed inspection (including a torque check on any affected 
nut) on each junction of flap torque-shaft 2 and slat torque-shafts 
2 and 4 of the right and left hand wing for discrepancies (including 
missing torque marking on any nut, any untorqued nut, or any missing 
bolt), and do all applicable corrective actions in accordance with 
the Accomplishment Instructions of Airbus Service Bulletin A350-27-
P022, Revision 00, dated June 6, 2018. Do all applicable corrective 
actions at the applicable times specified in paragraph 1.E., 
``Compliance,'' of Airbus Service Bulletin A350-27-P022, Revision 
00, dated June 6, 2018.

(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 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: 9-ANM-116-AMOC-REQUESTS@faa.gov. 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.
