Airworthiness Directives; Airbus SAS Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2019-03-
10, which applied to all Airbus SAS Model A300 series airplanes; and
Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model
A300 C4-605R Variant F airplanes (collectively called Model A300-600
series airplanes). AD 2019-03-10 required repetitive detailed visual
inspections of the main landing gear (MLG) leg components and
replacement of the MLG leg if cracked components are found. This AD
continues to require the actions required by AD 2019-03-10. For certain
airplanes, this AD also requires modification of the MLG hinge arm by
installing improved MLG hinge arm/barrel pins; an out-of-roundness
check of removed pins; repetitive inspections of any affected pins and
the associated connecting rod bushes, and replacement of the MLG leg if
cracked components are found; and installation of an improved spacer;
as specified in a European Union Aviation Safety Agency (EASA) AD,
which is incorporated by reference. This AD was prompted by reports of
cracks in MLG leg components and a determination that additional
actions (including inspections, modifications, and checks) are needed
to address the unsafe condition. The FAA is issuing this AD to address
the unsafe condition on these products.
DATES: This AD is effective July 16, 2021.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of July 16,
2021.

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0145, dated July 1, 2020 (EASA
AD 2020-0145) (also referred to as the Mandatory Continuing
Airworthiness Information, or the MCAI), to correct an unsafe condition
for all Airbus SAS Model A300 series airplanes; Model A300-600 series
airplanes; and Model A300F4-608ST airplanes. EASA AD 2020-0145
supersedes EASA AD 2018-0170, dated August 6, 2018 (which corresponds
to FAA AD 2019-03-10, Amendment 39-19562 (84 FR 5595, February 22,
2019) (AD 2019-03-10)). Model A300F4-608ST 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.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2019-03-10. AD 2019-03-10 applied to all
Airbus SAS Model A300 and A300-600 series airplanes. The NPRM published
in the Federal Register on December 8, 2020 (85 FR 78971). The NPRM was
prompted by reports of cracks in MLG leg components, and a
determination that additional actions (including inspections,
modifications, and out-of-roundness checks) are needed to address the
unsafe condition. The NPRM proposed to continue to require the actions
required by AD 2019-03-10. For certain airplanes, this AD also requires
modification of the MLG hinge arm by installing improved MLG hinge arm/
barrel pins; an out-of-roundness check of removed pins; repetitive
inspections of any affected pins and the associated connecting rod
bushes, and replacement of the MLG leg if cracked components are found;
and installation of an improved spacer; as specified in an EASA AD.
The FAA is issuing this AD to address cracking of certain
components in the MLG leg, which could result in an MLG collapse, and
consequent damage to the airplane and injury to the airplane occupants.
See the MCAI for additional background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The following presents the comments
received on the NPRM and the FAA's response to each comment.
Support for the NPRM
The Air Line Pilots Association, International (ALPA) and an
anonymous commenter indicated support for the NPRM.
Request To Clarify Inspection Threshold for Certain Airplanes
United Parcel Service (UPS Airlines) asked that the proposed AD be
revised to add a statement to clarify that the general visual
inspection (GVI) for Group 2 airplanes begins within 30 months after
the effective date of the FAA AD. UPS Airlines stated that it has been
accomplishing Airbus Service Bulletin A300-32-6120 at gear overhaul,
which replaces the old hinge arm barrel pin with a new hinge arm barrel
pin, prior to release of Airbus Service Bulletin A300-32-6121. UPS
Airlines further pointed out that Airbus Service Bulletin A300-32-6121
was released after Airbus Service Bulletin A300-32-6120 (pin
replacement), and added installation of a new spacer during gear
overhaul. UPS Airlines added that EASA AD 2020-0145 does not have clear
instructions for the initial inspection start date for airplanes with
modifications accomplished using Airbus Service Bulletin A300-32-6120
that have not accomplished Airbus Service Bulletin A300-32-6121.
Further, UPS Airlines asserted that this request is in line with the
30-month pin replacement threshold for airplanes equipped with the
older pin. Airplanes with the newer pins installed in the past three
years without the spacer installation, UPS Airlines also asserted, are
less prone to any safety or operational concerns than those with the
older pins.
The FAA does not agree with the commenter's request. In developing
an appropriate compliance time for this AD, the FAA considered the
urgency associated with the subject unsafe condition as well as the
recommendations of the manufacturer. The compliance time for the
initial GVI for Group 2 airplanes is ``Within 30 months after pin
replacement,'' as specified in EASA AD 2020-0145. Airbus Service
Bulletin A300-32-6120, which provides instructions for pin replacement,
was issued September 24, 2019. Therefore, the earliest possible
compliance time for the inspection would be 30 months from September
24, 2019. The FAA has not changed this AD in this regard.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this final rule as proposed, except for minor
editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
EASA AD 2020-0145 describes procedures for repetitive detailed
visual inspections of the MLG leg components and replacement of the MLG
leg if cracked components are found. EASA AD 2020-0145 also describes
procedures, for certain airplanes, for modification of the MLG hinge
arm by installing improved pins, which would terminate the repetitive
detailed inspections required by AD 2019-03-10; an out-of-roundness
check of removed pins; repetitive inspections of affected pins and the
associated connecting rod bushes for cracking, and replacement of the
MLG leg if cracked
[[Page 31099]]
components are found; and installation of an improved spacer, which
would terminate the repetitive pin and rod bushes inspections. EASA AD
2020-0145 also describes procedures for reporting results of the out-
of-roundness check to Safran.
Safran Landing Systems has issued Safran Service Bulletin 470-32-
840, dated December 3, 2019. This service information describes
procedures for inspecting the hinge arm pins of the MLG barrel to
detect local out-of-roundness.
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.
Costs of Compliance
The FAA estimates that this AD affects 128 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:

Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the
Information Collection Clearance Officer, Federal Aviation
Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.
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.
