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) 
2019-20-10, which applies to certain Airbus SAS Model A318 series 
airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 
airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 
airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and 
-232 airplanes. AD 2019-20-10 requires repetitive rototest inspections 
of the holes at the door stop fittings for any cracking, and corrective 
actions if necessary. Since the FAA issued AD 2019-20-10, a 
clarification of a certain compliance time for the rototest inspection 
was added. This proposed AD would clarify a certain compliance time and 
continue to require repetitive rototest inspections of the holes at the 
door stop fittings for any cracking, and repair if necessary, as 
specified in a European Union Aviation Safety Agency (EASA) AD, which 
is proposed for incorporation 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 2, 
2021.

Background

    The FAA issued AD 2019-20-10, Amendment 39-19763 (84 FR 61526, 
November 13, 2019) (AD 2019-20-10), which applies to certain Airbus SAS 
Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -
131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, 
-232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -
213, -231, and -232 airplanes. AD 2019-20-10 requires repetitive 
rototest inspections of the holes at the door stop fittings for any 
cracking, and corrective actions if necessary. The FAA issued AD 2019-
20-10 to address cracking of the web holes at the door stop fittings, 
which could affect the structural integrity of the airplane.

Actions Since AD 2019-20-10 Was Issued

    Since the FAA issued AD 2019-20-10, a clarification of the initial 
compliance time for the rototest inspection, related to the 
incorporation of certain airworthiness limitations (ALI) tasks has been 
added. Certain airworthiness limitations (ALI) tasks referenced in EASA 
AD 2018-0289, dated December 21, 2018 (which corresponds to FAA AD 
2019-20-10) were initially applicable only to the left- and right-hand 
door stop fitting holes at position 1 or 7 at fuselage frame (FR)20, 
and, at a later stage, were made applicable to the left- and right-hand 
door stop fitting holes at position 1 or 7 at fuselage FR16. An 
operator reported a possible misunderstanding of the compliance time in 
EASA AD 2018-0289. Therefore, EASA determined that the compliance time 
language related to accomplishment of those ALI tasks needed to be 
clarified.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0289R1, dated February 10, 2021 
(EASA AD 2018-0289R1) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Airbus SAS Model A318 series airplanes; Model A319-111, -
112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, 
-212, -214, -215, -216, -231, -232, and -233 airplanes; and Model A321-
111, -112, -131, -211, -212, -213, -231, and -232 airplanes. EASA AD 
2018-0289R1 supersedes EASA AD 2018-0289 (which corresponds to FAA AD 
2019-20-10). Model A320-215 airplanes are not certificated by the FAA 
and are not included on the U.S. type certificate data sheet; this AD 
therefore does not include those airplanes in the applicability.
    This proposed AD was prompted by a report that cracks were detected 
on FR16 and FR20 web holes and passenger door intercostal fitting holes 
at the door stop fitting locations. The FAA is proposing this AD to 
address cracking of the web holes at the door stop fittings, which 
could affect the structural integrity of the airplane. See the MCAI for 
additional background information.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2019-20-10, this proposed AD would retain all of the 
requirements of AD 2019-20-10. Those requirements are referenced in 
EASA AD 2018-0289R1, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

Related Service Information Under 1 CFR Part 51

    EASA AD 2018-0289R1 describes procedures for repetitive rototest 
inspections of the holes at the door stop fittings for any cracking and 
repair if necessary. 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 the FAA's 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 FAA 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2018-0289R1 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 initially 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. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2018-
0289R1 will be incorporated by reference in the FAA final rule. This 
proposed AD would, therefore, require compliance with EASA AD 2018-
0289R1 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 2018-0289R1 that is required for 
compliance with EASA AD 2018-0289R1 will be available on the internet 
at https://www.regulations.gov by searching for and locating Docket No. 
FAA-2021-0501 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 1,528 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

    The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need this on-condition action:

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.

List of Subjects in 14 CFR Part 39

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