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) 
2016-10-08, AD 2017-05-10, and AD 2019-01-05, which apply to certain 
Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes; 
and AD 2019-20-13, which applies to certain Airbus SAS Model A330-200, 
A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, and A340-
600 series airplanes. AD 2016-10-08 requires determining the flight 
cycles accumulated on certain trimmable horizontal stabilizer actuators 
(THSAs), and replacing the THSA if necessary. AD 2017-05-10, AD 2019-
01-05, and AD 2019-20-13 require revising the existing maintenance or 
inspection program, as applicable. Since the FAA issued those ADs, 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 additional new or more restrictive airworthiness 
limitations, 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 8, 
2022.

which is not specifically designated as CBI will be placed in the 
public docket for this rulemaking.

Background

    The FAA issued AD 2016-10-08, Amendment 39-18519 (81 FR 31844, May 
20, 2016) (AD 2016-10-08), which applies to certain Airbus SAS Model 
A330-200, A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, 
and A340-600 series airplanes. Airbus SAS Model A340-200, A340-300, 
A340-500, and A340-600 series airplanes were included in AD 2016-10-08, 
but are not included in this proposed AD. Airbus SAS Model A340-200, 
A340-300, A340-500, and A340-600 series airplanes are not included in 
this proposed AD because EASA included these airplanes in EASA AD 2021-
0250, dated November 17, 2021 (EASA AD 2021-0250), and the FAA has 
added the MCAI to the required airworthiness actions list (RAAL) for 
Model A340 airplanes. AD 2016-10-08 requires inspecting certain THSAs 
to determine the number of total flight cycles the THSA has 
accumulated, and replacing the THSA if necessary. The FAA issued AD 
2016-10-08 to detect and correct premature wear of the carbon friction 
disks on the no-back brake of the THSA. Such a condition could lead to 
reduced braking efficiency in certain load conditions and, in 
conjunction with the inability of the power gear train to keep the ball 
screw in its last commanded position, could result in uncommanded 
movements of the trimmable horizontal stabilizer and loss of control of 
the airplane.
    The FAA issued AD 2017-05-10, Amendment 39-18821 (82 FR 13379, 
March 13, 2017) (AD 2017-05-10), which applies to certain Airbus SAS 
Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 
2017-05-10 requires revising the maintenance or inspection program to 
incorporate new maintenance requirements and airworthiness limitations. 
The FAA issued AD 2017-05-10 to prevent reduced structural integrity 
and reduced control of these airplanes due to the failure of system 
components.
    The FAA issued AD 2019-01-05, Amendment 39-19544 (84 FR 4310, 
February 15, 2019) (AD 2019-01-05), which applies to certain Airbus SAS 
Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 
2019-01-05 requires revising the existing maintenance or inspection 
program to incorporate new maintenance requirements and airworthiness 
limitations. The FAA issued AD 2019-01-05 to prevent reduced airplane 
control due to the failure of system components. AD 2019-01-05 
specifies that accomplishing the revision required by paragraph (g) of 
that AD terminates all requirements of AD 2017-05-10.
    The FAA issued AD 2019-20-13, Amendment 39-19766 (84 FR 56378, 
October 22, 2019) (AD 2019-20-13), which applies to certain Airbus SAS 
Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 
2019-20-13 requires revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. The FAA issued AD 2019-20-13 to address the 
failure of system components, which could reduce the controllability of 
the airplane. AD 2019-20-13 specifies that accomplishing the actions 
required by that AD terminates all requirements of AD 2019-01-05. 
Additionally, AD 2019-20-13 specifies that accomplishing the action 
required by task number 274400-00004-1-E of Airbus A330 Airworthiness 
Limitations Section (ALS) Part 4, System Equipment Maintenance 
Requirements (SEMR), Revision 07, dated October 15, 2018, within the 
compliance time specified for that task in Airbus A330 Airworthiness 
Limitations Section (ALS) Part 4, System Equipment Maintenance 
Requirements (SEMR), Revision 07, dated October 15, 2018, terminates 
all requirements of AD 2017-25-13, Amendment 39-19127 (82 FR 59960, 
December 18, 2017) (AD 2017-25-13), for Airbus SAS Model A330-200, -200 
Freighter, and -300 series airplanes only. Lastly, AD 2019-20-13 
specifies that accomplishing the action required by task number 213100-
00001-1-E of Airbus A330 Airworthiness Limitations Section (ALS) Part 
4, System Equipment Maintenance Requirements (SEMR), Revision 07, dated 
October 15, 2018, within the compliance time specified for that task in 
Airbus A330 Airworthiness Limitations Section (ALS) Part 4, System 
Equipment Maintenance Requirements (SEMR), Revision 07, dated October 
15, 2018, terminates all requirements of AD 2014-16-22, Amendment 39-
17946 (79 FR 49442, August 21, 2014) (AD 2014-16-22) for Airbus SAS 
Model A330-200, -200 Freighter, and -300 series airplanes only.

Actions Since AD 2016-10-08, AD 2017-05-10, AD 2019-01-05, and AD 2019-
20-13 Were Issued

    Since the FAA issued AD 2016-10-08, AD 2017-05-10, AD 2019-01-05, 
and AD 2019-20-13, the FAA has determined that new or more restrictive 
airworthiness limitations are necessary. The required actions mandated 
in AD 2016-10-08 are incorporated into Airbus A330 Airworthiness 
Limitations Section (ALS) Part 4, System Equipment Maintenance 
Requirements (SEMR), Revision 08, dated July 1, 2021 (which is referred 
to in EASA AD 2021-0250, dated November 17, 2021) (EASA AD 2021-0250) 
(also referred to as the MCAI).
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0250 to correct an unsafe 
condition for all Airbus SAS Model A330-201, -202, -203, -223, and -243 
airplanes; Model A330-223F and -243F airplanes; Model A330-301, -302, -
303, -321, -322, -323, -341, -342, and -343 airplanes; Model A330-841 
airplanes; and Model A330-941 airplanes.
    Airplanes with an original airworthiness certificate or original 
export certificate of airworthiness issued after July 1, 2021, must 
comply with the airworthiness limitations specified as part of the 
approved type design and referenced on the type certificate data sheet; 
this AD therefore does not include those airplanes in the 
applicability.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to address the failure of system components, which 
could reduce the controllability of the airplane. See the MCAI for 
additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0250 describes airworthiness limitations for system 
equipment maintenance requirements.
    This proposed AD would require Airbus Service Bulletin A330-27-
3199, dated July 15, 2014, which the Director of the Federal Register 
approved for incorporation by reference as of June 24, 2016 (81 FR 
31844, May 20, 2016).
    This proposed AD would also require A330 Airworthiness Limitations 
Section (ALS) Part 4, System Equipment Maintenance Requirements (SEMR), 
Revision 07, dated October 15, 2018, which the Director of the Federal 
Register approved for incorporation by reference as of November 26, 
2019 (84 FR 56378, October 22, 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 the 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 the requirements of AD 2016-10-08 and 
AD 2019-20-13. This proposed AD would require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, which are specified in EASA 
AD 2021-0250 described previously, as proposed for incorporation by 
reference. Accomplishing the actions required by this proposed AD would 
terminate all requirements of AD 2014-16-22 for Airbus SAS Model A330-
200, -200 Freighter, and -300 series airplanes only, and would 
terminate all requirements of AD 2017-25-13 for Airbus SAS Model A330-
200, -200 Freighter, and -300 series airplanes only. Any differences 
with EASA AD 2021-0250 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). 
Compliance with these actions 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 (s)(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 2021-0250 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2021-0250 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 EASA AD 2021-0250 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 2021-
0250. Service information required by EASA AD 2021-0250 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2022-0682 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) or intervals may be used unless the actions and intervals 
are approved as an AMOC in accordance with the procedures specified in 
the AMOCs paragraph under ``Additional FAA Provisions.'' This new 
format includes a ``New Provisions for Alternative Actions and 
Intervals'' paragraph that does not specifically refer to AMOCs, but 
operators may still request an AMOC to use an alternative action or 
interval.

Costs of Compliance

    The FAA estimates that this proposed AD affects 138 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 2016-10-08 to be $255 per product (3 work-hours x $85 
per work-hour) for inspecting the THSA for a total cost for U.S. 
operators of $35,190. The retained on-condition cost for AD 2016-10-08 
is $724,511 per product (23 work-hours x $85 per work-hour). The FAA 
estimates the total cost per operator for the retained actions from AD 
2019-20-13 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

[[Page 37457]]

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.
