SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2005-15-11, Amendment 39-14200 (70 FR
43025, July 26, 2005) (AD 2005-15-11). AD 2005-15-11 applied to all BAE
Systems (Operations) Limited Model 4101 airplanes. AD 2005-15-11
required repetitive detailed and specialized inspections to detect
fatigue damage in the fuselage, replacement of certain bolt assemblies,
and corrective actions if necessary. The FAA issued AD 2005-15-11 to
address fatigue damage of the fuselage, door, engine nacelle,
empennage, and wing structures, which could result in reduced
structural integrity of the airplane.
The FAA also proposed to supersede AD 2016-07-09, Amendment 39-
18454 (81 FR 21263, April 11, 2016) (AD 2016-07-09). AD 2016-07-09
applied to all BAE Systems (Operations) Limited Model 4101 airplanes.
AD 2016-07-09 required a revision of the maintenance or inspection
program. The FAA issued AD 2016-07-09 to address failure of certain
structurally significant items, including the main landing gear and
nose landing gear, which could result in reduced structural integrity
of the airplane; and to prevent fuel vapor ignition sources, which
could result in a fuel tank explosion and consequent loss of the
airplane.
The FAA also proposed to supersede AD 2018-19-24, Amendment 39-
19425 (83 FR 49786, October 3, 2018) (AD 2018-19-24). AD 2018-19-24
applied to all BAE Systems (Operations) Limited Model 4101 airplanes.
AD 2018-19-24 required a one-time detailed inspection of a certain
fuselage frame and repair, if necessary, and a revision of the
maintenance or inspection program, as applicable, to incorporate new or
revised maintenance instructions and airworthiness limitations. The FAA
issued AD 2018-19-24 to address cracking in fuselage frame 90, which
could cause it to fail and thereby compromise the structural integrity
of the aircraft pressure hull. The FAA also issued AD 2018-19-24 to
address fatigue damage of various airplane structures, which could
result in reduced structural integrity of the airplane. AD 2018-19-24
specifies that accomplishing the revision required by that AD
terminates all requirements of AD 2005-15-11.
The NPRM published in the Federal Register on October 21, 2022 (87
FR 63973). The NPRM was prompted by AD G-2022-0006, dated March 30,
2022, issued by the Civil Aviation Authority (CAA), which is the
aviation authority for the United Kingdom (U.K.) (U.K. CAA) (referred
to after this as the MCAI). The MCAI states that the repetitive
inspection requirements for Structural Significant Items (SSI) 53-10-
029 were not addressed in European Union Aviation Safety Agency (EASA)
AD 2017-0187, and additional SSI inspections are necessary (inspections
for cracking of Hi-Shear (now LISL) collars). The MCAI also states that
failure to comply with new or more restrictive actions could result in
an unsafe condition.
In the NPRM, the FAA proposed to continue to require the actions in
ADs 2016-07-09 and 2018-19-24 and require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations. The FAA is issuing this AD
to address fatigue damage of various airplane structures and failure of
certain structurally significant items, which could result in reduced
structural integrity of the airplane. The FAA is also issuing this AD
to address fuel vapor ignition sources, which could result in a fuel
tank explosion and consequent loss of the airplane.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2022-1298.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
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
referenced above. The FAA reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD to address the unsafe condition on this product.
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.

(83 FR 49786, October 3, 2018); and
BAE Systems (Operations) Limited Alert Service Bulletin
J41-A53-058, dated December 6, 2016, which the Director of the Federal
Register approved for incorporation by reference as of November 7, 2018
(83 FR 49786, October 3, 2018).
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 the ADDRESSES section.
Costs of Compliance
The FAA estimates that this AD would affect 10 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA estimates the total cost per operator for the retained
actions from AD 2016-07-09 to be $7,650 (90 work-hours x $85 per work-
hour).
The FAA estimates the total cost per operator for the retained
maintenance or inspection program revision from AD 2018-19-24 to be
$7,650 (90 work-hours x $85 per work-hour).
The FAA has determined that revising the 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. Therefore, the
agency estimates the average total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).
The FAA estimates the total cost per operator for the new 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 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.
