Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2016-20-12, AD 2018-17-21, and AD 2019-14-04, which apply to certain 
Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2019-
14-04 requires revising the existing maintenance or inspection program, 
as applicable, to incorporate new or more restrictive airworthiness 
limitations and terminates the provisions of AD 2018-17-21, which in 
turn terminates the provisions of AD 2016-20-12. Since the FAA issued 
AD 2019-14-04, the FAA has determined that new or more restrictive 
airworthiness limitations are necessary. This proposed AD would require 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is proposed for incorporation by reference (IBR). 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 October 25, 
2024.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to 
Timothy Dowling, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, 
Suite 410, Westbury, NY 11590; telephone 206-231-3667; email 
[email protected]. Any commentary that the FAA receives that is 
not specifically designated as CBI will be placed in the public docket 
for this rulemaking.

Background

    The FAA issued AD 2019-14-04, Amendment 39-19682 (84 FR 35812, July 
25, 2019) (AD 2019-14-04), for certain Airbus SAS Model A318, A319, 
A320, and A321 series airplanes. AD 2019-14-04 was prompted by an MCAI 
originated by EASA, which is the Technical Agent for the Member States 
of the European Union. EASA issued AD 2018-0231, dated October 25, 2018 
(EASA AD 2018-0231) (which corresponds to FAA AD 2019-14-04), to 
correct an unsafe condition.
    AD 2019-14-04 requires revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive fuel airworthiness limitations. The FAA issued AD 2019-14-
04 to address the potential of ignition sources inside fuel tanks, 
which, in combination with flammable fuel vapors, could result in a 
fuel tank explosion and consequent loss of the airplane. AD 2019-14-04 
specifies that accomplishing the revision required by that AD 
terminates all requirements of AD 2018-17-21, Amendment 39-19375 (83 FR 
44209, August 30, 2018) (AD 2018-17-21). AD 2018-17-21 specifies that 
accomplishing the revision required by that AD terminates all 
requirements of AD 2016-20-12, Amendment 39-18678 (81 FR 72507, October 
20, 2016) (AD 2016-20-12). This proposed AD would supersede AD 2016-20-
12 and AD 2018-17-21 as those ADs have already been terminated.

Actions Since AD 2019-14-04 Was Issued

    Since the FAA issued AD 2019-14-04, EASA superseded AD 2018-0231 
and issued EASA AD 2024-0047, dated February 19, 2024 (EASA AD 2024-
0047) (referred to after this as the MCAI), for all Airbus SAS Model 
A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -
114, -115, -131, -132, -133, -151N, -153N, and -171N airplanes; Model 
A320-211, -212, -214, -215, -216, -231, -232, -233, -251N, -252N, -
253N, -271N, -272N, and -273N airplanes; and Model A321-111, -112, -
131, -211, -212, -213, -231, 232, -251N, -251NX, -252N, -252NX, -253N, 
-253NX, -271N, -271NX, -272N, and -272NX airplanes. Model A320-215 
airplanes are not certified by the FAA and are not included on the U.S. 
type certificate data sheet; this proposed AD therefore does not 
include those airplanes in the applicability. The MCAI states that new 
or more restrictive airworthiness limitations have been developed.
    Airplanes with an original airworthiness certificate or original 
export certificate of airworthiness issued after November 6, 2023, must 
comply with the airworthiness limitations specified as part of the 
approved type design and referenced on the type certificate data sheet; 
this proposed AD therefore does not include those airplanes in the 
applicability.
    The FAA is proposing this AD to address the potential of ignition 
sources inside fuel tanks, which, in combination with flammable fuel 
vapors, could result in a fuel tank explosion and consequent loss of 
the airplane. You may examine the MCAI in the AD docket at 
regulations.gov under Docket No. FAA-2024-2138.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed EASA AD 2024-0047. This material specifies new or 
more restrictive airworthiness limitations for fuel airworthiness 
limitations items and critical design configuration control limitations 
(CDCCLs).
    This proposed AD would also require Airbus A318/A319/A320/A321 
Airworthiness Limitations Section (ALS), Part 5, Fuel Airworthiness 
Limitations (FAL), Revision 05, dated June 13, 2018, which the Director 
of the Federal Register approved for incorporation by reference as of 
August 29, 2019 (84 FR 35812, July 25, 2019).
    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

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this NPRM after determining that 
the unsafe condition described previously is likely to exist or develop 
in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all of the requirements of AD 2019-
14-04. This proposed AD would also require revising the existing 
maintenance or inspection program, as applicable, to incorporate 
additional new or more restrictive airworthiness limitations, which are 
specified in EASA AD 2024-0047 already described, as proposed for 
incorporation by reference. Any differences with EASA AD 2024-0047 are 
identified as exceptions in the regulatory text of this AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
Critical Design Configuration Control

[[Page 73318]]

Limitations (CDCCLs). Compliance with these actions and CDCCLs is 
required by 14 CFR 91.403(c). For airplanes that have been previously 
modified, altered, or repaired in the areas addressed by this proposed 
AD, the operator may not be able to accomplish the actions described in 
the revisions. In this situation, to comply with 14 CFR 91.403(c), the 
operator must request approval for an alternative method of compliance 
(AMOC) according to paragraph (l)(1) of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, the 
FAA proposes to incorporate EASA AD 2024-0047 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2024-0047 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 EASA AD 2024-0047 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 EASA AD 2024-
0047. Material required by EASA AD 2024-0047 for compliance will be 
available at regulations.gov by searching for and locating Docket No. 
FAA-2024-2138 after the FAA final rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections), intervals, or CDCCLs may be used unless the actions, 
intervals, and CDCCLs are approved as an AMOC in accordance with the 
procedures specified in the AMOCs paragraph under ``Additional AD 
Provisions.'' This new format includes a ``New Provisions for 
Alternative Actions, Intervals, and CDCCLs'' paragraph that does not 
specifically refer to AMOCs, but operators may still request an AMOC to 
use an alternative action, interval, or CDCCL.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 1,920 airplanes of U.S. registry. The FAA estimates the 
following costs to comply with this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2019-14-04 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate.
    The FAA estimates the total cost per operator for the new proposed 
actions to be $7,650 (90 work-hours x $85 per work-hour).

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.

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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

(d) Subject

    Air Transport Association (ATA) of America Code 05, Time Limits/
Maintenance Checks.

(e) Unsafe Condition

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
issuing this AD to address the potential of ignition sources inside 
fuel tanks, which, in combination with flammable fuel vapors, could 
result in a fuel tank explosion and consequent loss of the airplane.

(f) Compliance

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

(g) Retained Revision of the Existing Maintenance or Inspection 
Program, With No Changes

    This paragraph restates the requirements of paragraph (g) of AD 
2019-14-04, with no changes. For airplanes with an original 
airworthiness certificate or original export certificate of 
airworthiness issued on or before June 13, 2018: Within 90 days 
after August 29, 2019 (the effective date of AD 2019-14-04), revise 
the existing maintenance or inspection program, as applicable, to 
incorporate the information specified in Airbus A318/A319/A320/A321 
Airworthiness Limitations Section (ALS), Part 5, Fuel Airworthiness 
Limitations (FAL), Revision 05, dated June 13, 2018. The initial 
compliance time for doing the tasks is at the time specified in 
Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS), 
Part 5, Fuel Airworthiness Limitations (FAL), Revision 05, dated 
June 13, 2018, or within 90 days after August 29, 2019, whichever 
occurs later. Accomplishing the revision of the existing maintenance 
or inspection program required by paragraph (i) of this AD 
terminates the requirements of this paragraph.

(h) Retained Restrictions on Alternative Actions, Intervals, and 
Critical Design Configuration Control Limitations (CDCCLs), With a New 
Exception

    This paragraph restates the requirements of paragraph (h) of AD 
2019-14-04, with a new exception. Except as required by paragraph 
(i) of this AD, after the maintenance or inspection program has been 
revised as required by paragraph (g) of this AD, no alternative 
actions (e.g., inspections), intervals, or CDCCLs may be used unless 
the actions, intervals, and CDCCLs are approved as an alternative 
method of compliance (AMOC) in accordance with the procedures 
specified in paragraph (l)(1) of this AD.

(i) New Revision of the Existing Maintenance or Inspection Program

    Except as specified in paragraph (j) of this AD: Comply with all

accordance with, European Union Aviation Safety Agency (EASA) AD 
2024-0047, dated February 19, 2024 (EASA AD 2024-0047). 
Accomplishing the revision of the existing maintenance or inspection 
program required by this paragraph terminates the requirements of 
paragraph (g) of this AD.

(j) Exceptions to EASA AD 2024-0047

    (1) This AD does not adopt the requirements specified in 
paragraphs (1) and (2) of EASA AD 2024-0047.
    (2) Paragraph (3) of EASA AD 2024-0047 specifies revising ``the 
AMP,'' within 12 months after its effective date, but this AD 
requires revising the existing maintenance or inspection program, as 
applicable, within 90 days after the effective date of this AD.
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2024-0047 is at the applicable 
``limitations'' and ``associated thresholds'' as incorporated by the 
requirements of paragraph (3) of EASA AD 2024-0047, or within 90 
days after the effective date of this AD, whichever occurs later.
    (4) This AD does not adopt the provisions specified in 
paragraphs (4) and (5) of EASA AD 2024-0047.
    (5) This AD does not adopt the ``Remarks'' section of EASA AD 
2024-0047.

(k) New Provisions for Alternative Actions, Intervals, and CDCCLs

    After the existing maintenance or inspection program has been 
revised as required by paragraph (i) of this AD, no alternative 
actions (e.g., inspections), intervals, and CDCCLs are allowed 
unless they are approved as specified in the provisions of the 
``Ref. Publications'' section of EASA AD 2024-0047.

(l) Additional AD Provisions

    The following provisions also apply to this AD:
