Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2022-25-18, which applies to certain BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ series airplanes. AD 2022-25-18 requires repetitive inspections for cracking of the main landing gear (MLG) side stay outer link and replacement if necessary. Since the FAA issued AD 2022-25-18, additional investigations of the causes of the cracking were conducted. This proposed AD would require a reduction of the repetitive visual inspection interval, provide optional repetitive special detailed inspections, accomplishing a one-off dimensional tolerance check and performing a repetitive lubrication of the MLG side stay outer link pivot, as specified in a United Kingdom (U.K.) Civil Aviation Authority (CAA) (U.K. CAA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2022-25-18, which applies to certain BAE Systems (Operations) Limited
Model BAe 146 and Model Avro 146-RJ series airplanes. AD 2022-25-18
requires repetitive inspections for cracking of the main landing gear
(MLG) side stay outer link and replacement if necessary. Since the FAA
issued AD 2022-25-18, additional investigations of the causes of the
cracking were conducted. This proposed AD would require a reduction of
the repetitive visual inspection interval, provide optional repetitive
special detailed inspections, accomplishing a one-off dimensional
tolerance check and performing a repetitive lubrication of the MLG side
stay outer link pivot, as specified in a United Kingdom (U.K.) Civil
Aviation Authority (CAA) (U.K. CAA) AD, which is proposed for
incorporation by reference (IBR). The FAA is proposing this AD to
address the unsafe condition on these products.

Background
The FAA issued AD 2022-25-18, Amendment 39-22274 (87 FR 75915,
December 12, 2022; corrected December 27, 2022 (87 FR 79236)) (AD 2022-
25-18), for certain BAE Systems (Operations) Limited Model BAe 146 and
Model Avro 146-RJ series airplanes. AD 2022-25-18 was prompted by an
MCAI originated by the U.K. CAA, which is the aviation authority for
the United Kingdom. U.K. CAA issued AD G-2022-0018, dated October 18,
2022, to correct an unsafe condition.
AD 2022-25-18 requires repetitive inspections for cracking of the
MLG side stay outer link and replacement if necessary. The FAA issued
AD 2022-25-18 to address cracking on the shoulders of a MLG side stay
outer link. The unsafe condition, if not addressed, could lead to
failure of the MLG side stay outer link and MLG collapse, which could
result in a runway departure and the engine or wing contacting the
ground. The engine or wing contacting the ground could result in damage
to the airplane, an increased risk of fire, the airplane flipping, and
injury to occupants.
Actions Since AD 2022-25-18 Was Issued
Since the FAA issued AD 2022-25-18, U.K. CAA superseded AD G-2022-
0018, dated October 18, 2022, and issued AD G-2023-0004R1, dated
November 16, 2023 (U.K. CAA AD G-2023-004R1) (also referred to as the
MCAI), to correct an unsafe condition for all BAE Systems (Operations)
Limited Model BAe 146-301, BAe 146-100A, -200A, and -300A airplanes and
Model Avro 146-RJ70A, 146-RJ85A, 146-RJ100A. Model BAe 146-301
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 MCAI states that further
investigation resulted in a reduced repetitive detailed visual
inspection interval and an option to do repetitive special detailed
inspections; a new requirement for a one-time dimensional tolerance
check; and a requirement to perform a repetitive lubrication of the MLG
side stay outer link pivot.
The FAA is proposing this AD to address cracking of the MLG side
stay outer link. The unsafe condition, could lead to failure of the MLG
side stay outer link and MLG collapse, which could result in a runway
departure and the engine or wing contacting the ground. The engine or
wing contacting the ground could result in damage to the airplane, an
increased risk of fire, the airplane flipping, and injury to occupants.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2023-2400.
Related Service Information Under 1 CFR Part 51
U.K. CAA AD G-2023-004R1 specifies procedures for doing repetitive
detailed visual inspections or special detailed inspections for
cracking of the MLG side stay outer link and replacement if necessary;
a one-time dimensional tolerance check of the MLG side stay outer link
and corrective actions including replacement if necessary: and
repetitive lubrication of the MLG side stay outer link pivot.
The FAA reviewed BAE Systems (Operations) Limited Alert Service
Bulletin (ASB) ASB.32-A189, Revision 2, dated August 3, 2023. This
service information describes procedures for doing, among other
actions, detailed visual inspections and special detailed inspections
(fluorescent dye penetrant) for cracking of the MLG side stay outer
link, replacement of the side stay outer link; a one-time dimensional
tolerance check of the MLG side stay outer link; removing the side stay
outer link and contacting the manufacturer; re-applying protective
treatment/paint; and lubrication of the MLG side stay outer link pivot.
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 and
service information 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 requires accomplishing the actions specified in
U.K. CAA AD G-2023-0004R1 described previously, except for any
differences identified as exceptions in the regulatory text of this
proposed AD.
Interim Action
The FAA considers that this proposed AD would be an interim action.
If final action is later identified, the FAA might consider further
rulemaking then.
[[Page 89341]]
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 U.K. CAA AD G-2023-004R1 by reference in
the FAA final rule. This proposed AD would, therefore, require
compliance with U.K. CAA AD G-2023-004R1 in its entirety through that
incorporation, except for any differences identified as exceptions in
the regulatory text of this proposed AD. Service information required
by U.K. CAA AD G-2023-004R1 for compliance will be available at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2023-2400 after the FAA final rule
is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 20 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170........................... $0 $170 $3,400
----------------------------------------------------------------------------------------------------------------
Estimated Costs for On-Condition Actions
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 5 work-hours x $85 per Up to $3,000...... Up to $3,425.
hour = Up to $425.
------------------------------------------------------------------------
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.
