SUPPLEMENTARY INFORMATION: 10259 MCAI’’), to correct an unsafe condition for certain Airbus SAS Model A320– 251N and –271N airplanes, and Model A321–253N airplanes. The MCAI states: Low clearance between electrical harness and nearby hydraulic pipes has been detected in the inboard trailing edge of some aeroplanes. This condition, if not detected and corrected, could lead to chafing of electrical harnesses on hydraulic pipes, eventually creating an ignition source in the flammable fluid leakage zone area, possibly resulting in fire or an explosion and loss of the aeroplane. To address this potential unsafe condition, Airbus issued the AOT [alert operators transmission], providing instructions to accomplish a detailed inspection (DET) for clearance and damage, and published the modification SB [Service Bulletin A320–29– 1176], providing instructions to modify the electrical harness routing, increasing the clearance between electrical harness and hydraulic pipes. For the reasons described above, this [EASA] AD requires repetitive DET of the electrical harness and modification of the aeroplane. Related IBR Material Under 1 CFR Part 51 EASA AD 2019–0035 describes procedures for repetitive detailed inspections of certain electrical harnesses for discrepancies (clearance and damage) and corrective actions, if necessary. Corrective actions include repairing the electrical harness or replacing the electrical harness sleeve, and increasing the clearance between the affected electrical harness and hydraulic pipe. This material 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, and it is publicly available through the EASA website. Discussion 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 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. The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0035, dated February 15, 2019 (‘‘EASA AD 2019–0035’’) (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the Requirements of This AD This AD requires accomplishing the actions specified in EASA AD 2019– 0035 described previously through the incorporated by reference of EASA AD 2019–0035, except for any differences identified as exceptions in the PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 E:\FR\FM\20MRR1.SGM 20MRR1 10260 Federal Register / Vol. 84, No. 54 / Wednesday, March 20, 2019 / Rules and Regulations regulatory text of this AD and except as discussed under ‘‘Differences Between this AD and the MCAI.’’ Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. As a result, EASA AD 2019–0035 is incorporated by reference in the FAA final rule. This AD, therefore, requires compliance with the provisions specified in EASA AD 2019–0035, except for any differences identified as exceptions in the regulatory text of this AD. Service information specified in EASA AD 2019–0035 that is required for compliance with EASA AD 2019–0035 is available on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 0121. Differences Between This AD and the MCAI EASA AD 2019–0035 specifies to modify the airplane (modification of the adaptation damper bulkhead fitting for left hand and right hand wings). For this Comments Invited AD, the modification, which would terminate the repetitive inspections required by this AD, is optional. However, we are considering further rulemaking to require this modification. The planned compliance time for the modification would allow enough time to provide notice and opportunity for prior public comment on the merits of the modification. This difference has been coordinated with EASA. 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–2019–0121; Product Identifier 2019–NM–025–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 based on those comments. We will post all comments we receive, without change, to https:// 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. 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 failure to detect and correct chafing of electrical harnesses in the vicinity of hydraulic pipes could result in a potential source of ignition in the flammable fluid leakage zone, and possibly result in a fire or explosion and loss 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. Costs of Compliance We estimate that this AD affects 14 airplanes 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 6 work-hours × $85 per hour = $510 .......................................................................................... $0 $510 $7,140 Labor cost Parts cost Cost per product 16 work-hours × $85 per hour = $1,360 ................................................................................................................. $8,900 $10,260 ESTIMATED COSTS FOR OPTIONAL ACTIONS We estimate the following costs for the necessary on-condition action 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 this on-condition action: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Up to 8 work-hours × $85 per hour = $680 ............................................................................................................ * $0 Cost per product Up to $680. jbell on DSK30RV082PROD with RULES * We have received no definitive data that would enable us to provide parts cost estimates. 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 VerDate Sep<11>2014 16:00 Mar 19, 2019 Jkt 247001 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 PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 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. E:\FR\FM\20MRR1.SGM 20MRR1 Federal Register / Vol. 84, No. 54 / Wednesday, March 20, 2019 / Rules and Regulations 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. List of Subjects in 14 CFR Part 39 jbell on DSK30RV082PROD with RULES Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: VerDate Sep<11>2014 16:00 Mar 19, 2019 Jkt 247001 optional modification specified in paragraph (h)(3) of this AD.

Temporary final rule. AGENCY: The Coast Guard is establishing a temporary safety zone on the navigable waters of the Missouri River from mile marker (MM) 450 to MM 625 between St. Joseph, MO and Omaha, NE. This action is necessary to provide for the safety of persons, vessels, and the marine environment on these navigable waters as a result of flooding on the river that has resulted in some reported levee failures and is threatening to overtop additional levees. Entry of vessels or persons into this zone is prohibited unless specifically authorized by the Captain of the Port Sector Upper Mississippi River (COTP) or a designated representative. DATES: This rule is effective without actual notice from March 20, 2019 until jbell on DSK30RV082PROD with RULES SUMMARY: VerDate Sep<11>2014 16:00 Mar 19, 2019 Jkt 247001 I.

SUPPLEMENTARY INFORMATION: II. Background Information and Regulatory History The Coast Guard is issuing this temporary rule without prior notice and opportunity to comment pursuant to authority under section 4(a) of the Administrative Procedure Act (APA) (5 U.S.C. 553(b)). This provision authorizes an agency to issue a rule without prior notice and opportunity to comment when the agency for good cause finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under 5 U.S.C. 553(b)(B), the Coast Guard finds that good cause exists for not publishing a notice of proposed rulemaking (NPRM) with respect to this rule because it is impracticable. It is impracticable because we must establish this safety zone immediately and lack sufficient time to provide a reasonable comment period and then consider those comments before issuing this rule. The NPRM process would delay the establishment of the safety zone and compromise public safety. Under 5 U.S.C. 553(d)(3), the Coast Guard finds that good cause exists for making this rule effective less than 30 days after publication in the Federal Register. Delaying this rule would be contrary to public interest because immediate action is necessary to PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 respond to the potential safety hazards associated with floodwaters threatening to overtop levees along the river. III. Legal Authority and Need for Rule The Coast Guard is issuing this rule under authority in 46 U.S.C. 70034. The COTP has determined that potential hazards associated with flood waters threaten to overtop levees along the river. The United States Army Corps of Engineers (USACE) Kansas City District has expressed concern that vessel traffic in the affected area could cause damage to the levees resulting in overtopping or failure. This rule is necessary to ensure the safety of persons, vessels, and the marine environment on these navigable waters due to the flood impacts to USACE levees. IV. Discussion of the Rule On March 14, 2019, the USACE Kansas City District contacted the Coast Guard to report flood waters approaching the tops of levees along the Missouri River between Mile Marker (MM) 450 and MM 550 and requested a river closure to ensure the safety of persons, vessels, and the marine environment that would result if floodwaters overtop the levees. On March 15, 2019, the Plattsmouth Fire Department reported a levee break along the river and requested a river closure to MM 625 at Omaha, NE. This rule establishes a temporary safety zone from March 15, 2019 until April 1, 2019, or until cancelled by the Captain of the Port Sector Upper Mississippi River (COTP). The safety zone will be enforced on all navigable waters of the Missouri River from MM 450 to MM 625, unless reduced in scope by the COTP as flood conditions warrant. No vessel or person will be permitted to enter the safety zone without obtaining permission from the COTP or a designated representative. A designated representative is a commissioned, warrant, or petty officer of the U.S. Coast Guard (USCG) assigned to units under the operational control of USCG Sector Upper Mississippi River. To seek permission to enter, contact the COTP or a designated representative via VHF–FM channel 16, or through USCG Sector Upper Mississippi River at 314– 269–2332. Persons and vessels permitted to enter the safety zone must comply with all lawful orders or directions issued by the COTP or designated representative. The COTP or a designated representative will inform the public of the effective period for the safety zone as well as any changes in the dates and times of enforcement, as well as reductions in size of the safety zone as flood conditions improve, through E:\FR\FM\20MRR1.SGM 20MRR1

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0035, dated February 15, 2019 
(``EASA AD 2019-0035'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus SAS Model A320-251N and -271N airplanes, 
and Model A321-253N airplanes. The MCAI states:

    Low clearance between electrical harness and nearby hydraulic 
pipes has been detected in the inboard trailing edge of some 
aeroplanes.
    This condition, if not detected and corrected, could lead to 
chafing of electrical harnesses on hydraulic pipes, eventually 
creating an ignition source in the flammable fluid leakage zone 
area, possibly resulting in fire or an explosion and loss of the 
aeroplane.
    To address this potential unsafe condition, Airbus issued the 
AOT [alert operators transmission], providing instructions to 
accomplish a detailed inspection (DET) for clearance and damage, and 
published the modification SB [Service Bulletin A320-29-1176], 
providing instructions to modify the electrical harness routing, 
increasing the clearance between electrical harness and hydraulic 
pipes.
    For the reasons described above, this [EASA] AD requires 
repetitive DET of the electrical harness and modification of the 
aeroplane.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0035 describes procedures for repetitive detailed 
inspections of certain electrical harnesses for discrepancies 
(clearance and damage) and corrective actions, if necessary. Corrective 
actions include repairing the electrical harness or replacing the 
electrical harness sleeve, and increasing the clearance between the 
affected electrical harness and hydraulic pipe. This material 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, and it is publicly available through the EASA 
website.

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 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 EASA AD 
2019-0035 described previously through the incorporated by reference of 
EASA AD 2019-0035, except for any differences identified as exceptions 
in the

[[Page 10260]]

regulatory text of this AD and except as discussed under ``Differences 
Between this AD and the MCAI.''

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA worked with Airbus and EASA to develop a process to 
use certain EASA ADs as the primary source of information for 
compliance with requirements for corresponding FAA ADs. As a result, 
EASA AD 2019-0035 is incorporated by reference in the FAA final rule. 
This AD, therefore, requires compliance with the provisions specified 
in EASA AD 2019-0035, except for any differences identified as 
exceptions in the regulatory text of this AD. Service information 
specified in EASA AD 2019-0035 that is required for compliance with 
EASA AD 2019-0035 is available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0121.

Differences Between This AD and the MCAI

    EASA AD 2019-0035 specifies to modify the airplane (modification of 
the adaptation damper bulkhead fitting for left hand and right hand 
wings). For this AD, the modification, which would terminate the 
repetitive inspections required by this AD, is optional. However, we 
are considering further rulemaking to require this modification. The 
planned compliance time for the modification would allow enough time to 
provide notice and opportunity for prior public comment on the merits 
of the modification. This difference has been coordinated with EASA.

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 failure to detect and correct chafing of electrical harnesses 
in the vicinity of hydraulic pipes could result in a potential source 
of ignition in the flammable fluid leakage zone, and possibly result in 
a fire or explosion and loss 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.

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-2019-0121; Product 
Identifier 2019-NM-025-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 based on 
those comments.
    We will post all comments we receive, without change, to https://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 14 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.

16 work-hours x $85 per hour = $1,360.          $8,900          $10,260
------------------------------------------------------------------------

    We estimate the following costs for the necessary on-condition 
action 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 this on-condition action:

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
           Labor cost               Parts cost       Cost per  product
------------------------------------------------------------------------
Up to 8 work-hours x $85 per              \*\ $0  Up to $680.

------------------------------------------------------------------------
* We have received no definitive data that would enable us to provide
  parts cost estimates.

    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.

[[Page 10261]]

    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):

2019-05-09 Airbus SAS: Amendment 39-19591; Docket No. FAA-2019-0121; 
Product Identifier 2019-NM-025-AD.

(a) Effective Date

    This AD becomes effective April 4, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus SAS Model A320-251N and -271N 
airplanes, and Model A321-253N airplanes, certificated in any 
category, as identified in European Aviation Safety Agency (EASA) AD 
2019-0035, dated February 15, 2019 (``EASA AD 2019-0035'').

(d) Subject

    Air Transport Association (ATA) of America Code 92, Electric and 
electronic common installation.

(e) Reason

    This AD was prompted by reports of low clearance between the 
electrical harness and nearby hydraulic pipes in the inboard 
trailing edge of the wing. We are issuing this AD to address this 
condition, which, if not detected and corrected, could lead to 
chafing of electrical harnesses in the vicinity of hydraulic pipes 
and could result in a potential source of ignition in the flammable 
fluid leakage zone, and possibly result in a fire or explosion and 
loss of the airplane.

(f) Compliance

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

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, EASA AD 2019-0035.

(h) Exceptions to EASA AD 2019-0035

    (1) For purposes of determining compliance with the requirements 
of this AD: Where EASA AD 2019-0035 refers to its effective date, 
this AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2019-0035 does not apply 
to this AD.
    (3) Where paragraph (4) of EASA AD 2019-0035 specifies to modify 
the airplane in accordance with Airbus Service Bulletin A320-29-
1176, this AD does not require modification of the airplane, but 
this AD allows that modification as an optional terminating action 
for the required repetitive inspections.
    (4) The provisions of paragraph (6) of EASA AD 2019-0035 are 
allowed in the optional modification specified in paragraph (h)(3) 
of this AD.

(i) No Reporting Requirement

    Although certain service information referenced in EASA AD 2019-
0035 specifies to submit certain information to the manufacturer, 
this AD does not include that requirement.

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 instructions from a manufacturer, the instructions must be 
accomplished using a method approved by the Manager, International 
Section, Transport Standards Branch, FAA; or 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): For any service information 
referenced in EASA AD 2019-0035 that contains RC procedures and 
tests: Except as required by paragraph (j)(2) of this AD, RC 
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.
