Abstract
The FAA proposes to supersede Airworthiness Directives (ADs) 2005-15-11, 2016-07-09, and 2018-19-24, which apply to all BAE Systems (Operations) Limited Model 4101 airplanes. AD 2005-15-11 requires repetitive detailed and specialized inspections to detect fatigue damage in the fuselage, replacement of certain bolt assemblies, and corrective actions if necessary. AD 2016-07-09 requires a revision of the maintenance or inspection program, as applicable. AD 2018-19-24 requires 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. Since the FAA issued those ADs, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 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 proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; BAE Systems (Operations) Limited
Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directives (ADs)
2005-15-11, 2016-07-09, and 2018-19-24, which apply to all BAE Systems
(Operations) Limited Model 4101 airplanes. AD 2005-15-11 requires
repetitive detailed and specialized inspections to detect fatigue
damage in the fuselage, replacement of certain bolt assemblies, and
corrective actions if necessary. AD 2016-07-09 requires a
[[Page 63974]]
revision of the maintenance or inspection program, as applicable. AD
2018-19-24 requires 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. Since
the FAA issued those ADs, the FAA has determined that new or more
restrictive airworthiness limitations are necessary. This proposed AD
would continue to require the actions in AD 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 proposing this AD to address the unsafe
condition on these products.

Background
The FAA issued AD 2005-15-11, Amendment 39-14200 (70 FR 43025, July
26, 2005) (AD 2005-15-11) for all BAE Systems (Operations) Limited
Model 4101 airplanes. AD 2005-15-11 was prompted by MCAI originated by
the Civil Aviation Authority (CAA), which is the aviation authority for
the United Kingdom (U.K.) (U.K. CAA). The U.K. CAA issued AD 2005-15-11
to correct an unsafe condition identified by a review of primary
airframe fatigue test results and a Maintenance Steering Group 3 (MSG-
3) analysis, which found a need to issue an AD to detect and correct
fatigue damage of the fuselage, door, engine nacelle, empennage, and
wing structures, which could result in reduced structural integrity of
the airplane.
AD 2005-15-11 requires 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 issued AD 2016-07-09, Amendment 39-18454 (81 FR 21263,
April 11, 2016) (AD 2016-07-09), for all BAE Systems (Operations)
Limited Model 4101 airplanes. AD 2016-07-09 was prompted by MCAI
originated by the European Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Union. EASA
issued AD 2014-0043, dated February 21, 2014 (EASA AD 2014-0043), to
correct an unsafe condition identified as failure of certain
structurally significant items, including the main landing gear and
nose landing gear, and fuel vapor ignition sources.
AD 2016-07-09 requires 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 issued AD 2018-19-24, Amendment 39-19425 (83 FR 49786,
October 3, 2018) (AD 2018-19-24), for all BAE Systems (Operations)
Limited Model 4101 airplanes. AD 2018-19-24 was prompted by MCAI
originated by
[[Page 63975]]
EASA. EASA issued AD 2017-0187, September 22, 2017 (EASA AD 2017-0187),
to correct an unsafe condition identified as cracking in fuselage frame
90 and fatigue damage of various airplane structures.
AD 2018-19-24 requires 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.
Actions Since ADs 2015-15-11, 2016-07-09, and 2018-19-24 Were Issued
Since the FAA issued ADs 2015-15-11, 2016-07-09, and 2018-19-24,
the U.K. CAA superseded EASA ADs 2014-0043 and 2017-0187, and issued
U.K. CAA AD G-2022-0006, dated March 30, 2022 (U.K. CAA AD G-2022-0006;
also referred to as the MCAI). U.K. CAA AD G-2022-0006 states that the
repetitive inspection requirements for Structural Significant Items
(SSI) 53-10-029 were not addressed in EASA AD 2017-0187, and additional
SSI inspections are necessary (inspections for cracking of Hi-Shear
(now LISL)) collars. U.K. CAA AD G-2022-0006 also states that failure
to comply with new or more restrictive actions could result in an
unsafe condition. 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 U.K. CAA AD G-2022-
0006 in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2022-
1298.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Chapter 05 of BAE Systems (Operations) Limited
J41Aircraft Maintenance Manual (AMM), Revision 44, dated June 15, 2021,
for effectivity group 403; and BAE Systems (Operations) Limited J41
AMM, Revision 44, dated June 15, 2021, for effectivity group 408. This
service information specifies airworthiness limitations for fuel tank
systems and certification maintenance requirements. These documents are
distinct since they apply to different airplanes.
This proposed AD would also require:
<bullet> Subjects 05-10-10, ``Airworthiness Limitations''; 05-10-
20, ``Certification Maintenance Requirements''; and 05-10-30,
``Critical Design Configuration Control Limitations (CDCCL)--Fuel
System''; of Chapter 05, ``Airworthiness Limitations,'' of the BAE
Systems (Operations) Limited J41 AMM, Revision 38, dated September 15,
2013, which the Director of the Federal Register approved for
incorporation by reference as of May 16, 2016 (81 FR 21263, April 11,
2016);
<bullet> BAE Systems (Operations) Limited Service Bulletin J41-51-
001, Revision 4, dated July 11, 2017, which the Director of the Federal
Register approved for incorporation by reference as of November 7, 2018
(83 FR 49786, October 3, 2018); and
<bullet> 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.
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 and
service information described above. The FAA is issuing this NPRM after
determining that the unsafe condition described previously is likely to
exist or develop on other products of the same type design.
Proposed Requirements of This NPRM
This proposed AD would retain none of the requirements of AD 2005-
15-11; certain requirements of AD 2016-07-09; and all requirements of
AD 2018-19-24. This proposed AD would require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations.
This proposed AD would require revisions to certain operator
maintenance documents to include new actions (e.g., inspections) and
Critical Design Configuration Control Limitations (CDCCLs). Compliance
with these actions and CDCCLs 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 according to paragraph
(o)(1) of this proposed AD.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 10 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 2016-07-09 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 proposed
actions to be $7,650 (90 work-hours x $85 per work-hour).

The FAA has received no definitive data on which to base the cost
estimates for the on-condition actions specified in this AD.
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.

in the ``Time Between Checks'' column in Subject 05-10-20, or within
90 days after May 16, 2016 (the effective date of AD 2016-07-09),
whichever occurs later; except for tasks that specify ``first flight
of the day'' in the ``Time Between Checks'' column in Subject 05-10-
20, the
[[Page 63977]]
initial compliance time is the first flight of the next day after
doing the revision required by paragraph (g) of AD 2016-07-09, or
within 90 days after May 16, 2016, whichever occurs later.
(h) Retained Restrictions on Alternative Actions, Intervals, and/or
(CDCCLs), With No Changes
This paragraph restates the requirements of paragraph (j) of AD
2016-07-09, with no changes. Except as required by paragraph (m) of
this AD, after the maintenance or inspection program, as applicable,
has been revised as required by paragraph (g) of this AD, no
alternative actions (e.g., inspections), intervals, and/or CDCCLs
may be used unless the actions, intervals, and/or CDCCLs are
approved as an alternative method of compliance (AMOC) in accordance
with the procedures specified in paragraph (o)(1) of this AD.
(i) Retained Inspection, With No Changes
This paragraph restates the requirements of paragraph (g) of AD
2018-19-24, with no changes. At the compliance times specified in
