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 regulations.gov 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:
     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);
     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
     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).

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.
