The MCAI states: the unsafe condition described previously is likely to exist or develop in other products of the same type design. During some flight tests of [Airbus SAS] A320 and A321 NEO (new engine option) aeroplanes, the regulated bleed temperature was measured above the design target with a temperature regulation shift phenomenon. The investigation results show that incorrect temperature regulation can degrade pneumatic system components located downstream of the pre-cooler. This condition, if not corrected, could lead to hot air leakage and consequent bleed loss, possibly resulting in the reduction of the system equipment safety margin. To address this potential unsafe condition, Airbus developed an improved BMC SW, and issued the SB [service bulletin] A320–36– 1078 to provide instructions for BMC SW uploading. For the reasons described above, this [EASA] AD requires modification of the affected parts and prohibits (re)installation of affected parts. Explanation of Required Compliance Information Related IBR Material Under 1 CFR Part 51 EASA AD 2019–0094 describes procedures for uploading BMC SW standard 4.3. 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. 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 a bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because the agency evaluated all the relevant information and determined Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2019–0094 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. 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 2019–0094 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 219–0094 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in the EASA AD does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in the EASA AD. Service information specified in EASA AD 2019–0094 that is required for compliance with EASA AD 2019–0094 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2019– 0522 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 85 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: jbell on DSK3GLQ082PROD with PROPOSALS ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 4 work-hours × $85 per hour = $340 .......................................................................................... $0 $340 $28,900 VerDate Sep<11>2014 18:54 Jul 05, 2019 Jkt 247001 PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 E:\FR\FM\08JYP1.SGM 08JYP1 32340 Federal Register / Vol. 84, No. 130 / Monday, July 8, 2019 / Proposed Rules The Proposed Amendment 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. The FAA is 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 and associated appliances to the Director of the System Oversight Division. Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: Regulatory Findings jbell on DSK3GLQ082PROD with PROPOSALS (i) Other FAA AD Provisions Authority for This Rulemaking The FAA 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. Will not affect intrastate aviation in Alaska; and 3. 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.

AD 2017–12–07 requires replacing the affected left temperature control valve and control cabin trim air modulating valve. AD 2017–12–07 resulted from reports of in-flight failure of the left temperature control valve and control cabin trim air modulating valve. The FAA issued AD 2017–12–07 to address the possible occurrence of temperatures in excess of 100 degrees Fahrenheit in the flight deck or the passenger cabin during cruise, which could lead to the impairment of the flightcrew and prevent continued safe flight and landing. Actions Since AD 2017–12–07 Was Issued Since AD 2017–12–07 was issued, it has been determined that the affected parts may be installed as rotable spares on airplanes outside of the applicability of AD 2017–12–07, thereby subjecting those airplanes to the unsafe condition.

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus SAS Model A320-251N and -271N airplanes, and Model A321-
251N, -253N, -271N, and -272N airplanes. This proposed AD was prompted 
by reports that the regulated bleed temperature was measured above the 
design target with a temperature regulation shift phenomenon, and 
investigation results show that incorrect temperature regulation can 
degrade pneumatic system components located downstream of the pre-
cooler. This proposed AD would require uploading improved bleed 
monitoring computer (BMC) software (SW), as specified in a European 
Aviation Safety Agency (EASA) AD, which will be incorporated by 
reference. The FAA is proposing this AD to address the unsafe condition 
on these products.

DATES: The FAA must receive comments on this proposed AD by August 22, 
2019.

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0094, dated April 26, 2019 
(``EASA AD 2019-0094'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A320-251N and -271N airplanes, and 
Model A321-251N, -253N, -271N, and -272N airplanes. The MCAI states:

    During some flight tests of [Airbus SAS] A320 and A321 NEO (new 
engine option) aeroplanes, the regulated bleed temperature was 
measured above the design target with a temperature regulation shift 
phenomenon. The investigation results show that incorrect 
temperature regulation can degrade pneumatic system components 
located downstream of the pre-cooler.
    This condition, if not corrected, could lead to hot air leakage 
and consequent bleed loss, possibly resulting in the reduction of 
the system equipment safety margin.
    To address this potential unsafe condition, Airbus developed an 
improved BMC SW, and issued the SB [service bulletin] A320-36-1078 
to provide instructions for BMC SW uploading.
    For the reasons described above, this [EASA] AD requires 
modification of the affected parts and prohibits (re)installation of 
affected parts.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0094 describes procedures for uploading BMC SW 
standard 4.3. 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.

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 a bilateral agreement with the State of Design Authority, the FAA 
has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is proposing this AD because the agency 
evaluated all the relevant information and determined the unsafe 
condition described previously is likely to exist or develop in other 
products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2019-0094 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this AD.

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 2019-0094 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with EASA 
AD 219-0094 in its entirety, through that incorporation, except for any 
differences identified as exceptions in the regulatory text of this 
proposed AD. Using common terms that are the same as the heading of a 
particular section in the EASA AD does not mean that operators need 
comply only with that section. For example, where the AD requirement 
refers to ``all required actions and compliance times,'' compliance 
with this AD requirement is not limited to the section titled 
``Required Action(s) and Compliance Time(s)'' in the EASA AD. Service 
information specified in EASA AD 2019-0094 that is required for 
compliance with EASA AD 2019-0094 will be available on the internet at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2019-0522 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 85 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

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.
    The FAA is 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 and associated appliances to the 
Director of the System Oversight Division.

Regulatory Findings

    The FAA 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. Will not affect intrastate aviation in Alaska; and
    3. 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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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-2019-0522; Product Identifier 2019-NM-
082-AD.

(a) Comments Due Date

    The FAA must receive comments by August 22, 2019.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus SAS Model A320-251N and -271N 
airplanes, and Model A321-251N, -253N, -271N, and -272N airplanes, 
certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 36, Pneumatic.

accordance with, European Aviation Safety Agency (EASA) AD 2019-
0094, dated April 26, 2019 (``EASA AD 2019-0094'').

(h) Exceptions to EASA AD 2019-0094

    (1) For purposes of determining compliance with the requirements 
of this AD: Where EASA AD 2019-0094 refers to its effective date, 
this AD requires using the effective date of this AD.
    (2) The ``Remarks'' section of EASA AD 2019-0094 does not apply 
to this AD.

(i) 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 (j)(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 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 2019-0094 that contains RC procedures and 
tests: Except as required by paragraph (i)(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.
