Abstract
The FAA is superseding Airworthiness Directive (AD) 2020-16- 01, which applied to all Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2020-16-01 required repetitive cleaning and greasing of affected cargo door seals (both original equipment manufacturer (OEM) and parts manufacturer approval (PMA) parts). This AD was prompted by reports of low halon concentration in the forward and aft cargo compartments due to air leakage through cargo compartment door seals, and the FAA's determination that improved cargo door seals must be installed and that certain flight operations must be limited until the improved cargo door seals are installed. This AD retains certain actions required by AD 2020-16-01 and requires replacing certain forward and aft cargo compartment door seals with new seals and installing a placard on the cargo compartment doors; and for certain airplanes, revising the existing airplane flight manual (AFM) to implement an operational limitation for certain routes. The FAA is issuing this AD to address the unsafe condition on these products.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-16-
01, which applied to all Airbus SAS Model A318, A319, A320, and A321
series airplanes. AD 2020-16-01 required repetitive cleaning and
greasing of affected cargo door seals (both original equipment
manufacturer (OEM) and parts manufacturer approval (PMA) parts). This
AD was prompted by reports of low halon concentration in the forward
and aft cargo compartments due to air leakage through cargo compartment
door seals, and the FAA's determination that improved cargo door seals
must be installed and that certain flight operations must be limited
until the improved cargo door seals are installed. This AD retains
certain actions required by AD 2020-16-01 and requires replacing
certain forward and aft cargo compartment door seals with new seals and
installing a placard on the cargo compartment doors; and for certain
airplanes, revising the existing airplane flight manual (AFM) to
implement an operational limitation for certain routes. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective April 11, 2022.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of April 11,
2022.
The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2020-16-01, Amendment 39-21185 (85 FR
47013, August 4, 2020) (AD 2020-16-01). AD 2020-16-01 applied to all
Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2020-
16-01 required repetitive cleaning and greasing of affected cargo door
seals (both OEM and PMA parts). The NPRM published in the Federal
Register on October 22, 2021 (86 FR 58597). The NPRM was prompted by
reports of low halon concentration in the forward and aft cargo
compartments due to air leakage through cargo compartment door seals,
and the FAA's determination that additional rulemaking is necessary to
require replacement of PMA part number (P/N) D5237106020400S with
improved cargo door seals and to limit certain flight operations until
the improved cargo door seals are installed. In the NPRM, the FAA
proposed to retain certain actions required by AD 2020-16-01; require
replacing certain forward and aft cargo compartment door seals with new
seals and installing a placard on the cargo compartment doors; and for
certain airplanes, implement an operational limitation for certain
routes. In the NPRM, the FAA proposed to limit the applicability to
airplanes that have certain PMA parts installed because the FAA issued
AD 2021-18-04, Amendment 39-21705 (86 FR 51265, September 15, 2021) (AD
2021-18-04) to address the OEM parts.
The FAA is issuing this AD to address low halon concentration. This
condition, if not corrected, could affect the fire extinguishing system
efficiency in the cargo compartments, possibly resulting in failure of
the system to contain a cargo compartment fire.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from Air Line Pilots Association, Inc.
(ALPA), who supported the NPRM without change, and United Airlines, who
also supported the NPRM. The FAA also received additional comments from
United Airlines. The following presents the comments received on the
NPRM and the FAA's response to each comment.
Request for Clarification if the Proposed AD Replaces or Supersedes a
Certain AD
United Airlines requested that the FAA clarify whether the proposed
AD would ``supersede'' AD 2020-16-01, as specified in the SUMMARY of
the NPRM, or would ``replace'' AD 2020-16-01, as specified in paragraph
(b) of the proposed AD.
The FAA agrees to clarify. The words supersede and replace have the
same meaning and are interchangeable. The word ``replace'' used in
paragraph (b) of this AD is required by the Office of the Federal
Register. The FAA has not changed this AD in this regard.
Request To Allow Later Revisions of Service Information
United Airlines requested that the FAA allow the use of later
approved revisions of Airbus Service Bulletin A320-52-1195, Revision
01, dated December 15, 2020, and Airbus Service Bulletin A320-52-1196,
dated October 12, 2020, as acceptable methods of compliance with the
requirements of the new proposed AD.
The FAA may not refer to any document that does not yet exist in an
AD. In general terms, the FAA is required by Office of the Federal
Register (OFR) regulations for approval of materials incorporated by
reference, as specified in 1 CFR 51.1(f), to either publish the service
document contents as part of the actual AD language; or submit the
service document to the OFR for approval as referenced material, in
which case the FAA may only refer to such material in the text of an
AD. The AD may refer to the service document only if the OFR approved
it for incorporation by reference. See 1 CFR part 51.
To allow operators to use later revisions of the referenced
document (issued after publication of the AD), either the FAA must
revise the AD to reference specific later revisions, or operators must
request approval to use later revisions as an alternative method of
compliance with this AD under the provisions of paragraph (m) of this
AD.
Inquiry Regarding Affected AD Number in AD 2018-18-04
United Airlines stated that paragraph (b) of AD 2021-18-04,
``Affected ADs,'' refers to AD 2020-16-01. United Airlines inquired
whether the FAA is planning to revise the ``Affected ADs'' paragraph of
AD 2021-18-04 with the new proposed AD number that is superseding or
replacing AD 2020-16-01.
The FAA agrees to clarify. AD 2021-18-04 applies only to OEM parts
and affects AD 2020-16-01 because AD 2020-16-01 applied to both OEM
parts and PMA parts. This AD applies only to PMA parts and supersedes
AD 2020-16-01. The terminating actions for cleaning and greasing as
required by AD 2021-18-04, AD 2020-16-01, and this new AD (that will
replace AD 2020-16-01), are the same: Replace the seals with new seal
part numbers as specified in the service information. However, AD 2021-
18-04 does not affect this AD as each AD is independent of each other.
It is not necessary to change paragraph (b) of AD 2021-18-04 to refer
to this AD because this AD does not contain any requirements for OEM
parts.
Clarification of Operational Limitation
Paragraph (j) of the proposed AD included an operational limitation
and specified that amending the existing AFM was one method to comply
with the requirement. The FAA has determined that revising the existing
AFM is the method most operators would use to comply with the
requirement. In addition, the FAA determined the AFM revision should
refer to the operational limitation language as specified in a figure
for clarity. The FAA has revised paragraph
[[Page 12567]]
(j) of this AD to require revising the existing AFM to include an
operational limitation specified in figure 1 to paragraph (j) of this
AD. Operators may request an alternative method of compliance using the
procedures specified in paragraph (m) of this AD if they have
alternative methods to comply with the operational limitations that
provide an equivalent level of safety.
Conclusion
The FAA reviewed the relevant data, considered any comments
received, and determined that air safety requires adopting this AD as
proposed. Except for minor editorial changes, this AD is adopted as
proposed in the NPRM. None of the changes will increase the economic
burden on any operator.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Airbus Service Bulletin A320-52-1195, Revision 01,
dated December 15, 2020, and Airbus Service Bulletin A320-52-1196,
dated October 12, 2020. This service information specifies procedures
for replacing the forward and aft cargo compartment door seals with new
seals, among other actions, and installing a placard on the cargo
compartment doors. These documents are distinct since they apply to
different airplane models.
This AD also requires European Union Aviation Safety Agency (EASA)
AD 2021-0049, dated February 18, 2021, which the Director of the
Federal Register approved for incorporation by reference as of October
20, 2021 (86 FR 51265, September 15, 2021).
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 ADDRESSES.
Costs of Compliance
The FAA estimates that this AD affects 1,768 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this 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.
Regulatory Findings
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) 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.

(e) Unsafe Condition
This AD was prompted by reports of low halon concentration in
the forward and aft cargo compartments due to air leakage through
cargo compartment door seals, and the certification of improved
cargo door seals. The FAA is issuing this AD to address low halon
concentration. This condition, if not corrected, could affect the
fire extinguishing system efficiency in the cargo compartments,
possibly resulting in failure of the system to contain a cargo
compartment fire.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Definition
For the purposes of this AD, a ``PMA part'' is defined as any
PMA part approved for the type design forward and aft cargo

to PMA P/N D5237106020400S.
(h) Retained Cleaning and Greasing, With Revised Compliance Language
This paragraph restates the requirements of paragraph (g) of AD
2020-16-01, with revised compliance language. Within 6 months after
the airplane date of manufacture, or 3 months after August 19, 2020
(the effective date of AD 2020-16-01), whichever occurs later, and,
thereafter, at intervals not exceeding 6 months, clean and grease
each PMA part, in accordance with the instructions specified in
paragraph (1) or (2) of European Union Aviation Safety Agency (EASA)
AD 2021-0049, dated February 18, 2021. Accomplishing the actions
required by paragraph (i) of this AD on an airplane terminates the
actions required by this paragraph for that airplane only, and for
the specific cargo door locations with PMA parts only.
(i) Modification
Within 96 months after the effective date of this AD, replace
the seals of the PMA part with new seals and install a placard on
the cargo compartment doors, in accordance with the method specified
in paragraph (i)(1) or (2) of this AD. Accomplishing the actions
required by this paragraph terminates the actions required by
paragraph (h) of this AD for that airplane only, and for the
specific cargo door locations where PMA parts were replaced only.
(1) Do the actions in accordance with the Accomplishment
Instructions of Airbus Service Bulletin A320-52-1195, Revision 01,
dated December 15, 2020, or Airbus Service Bulletin A320-52-1196,
