ACTION: Final rule. AGENCY: Background The FAA is adopting a new airworthiness directive (AD) for all BAE Systems (Operations) Limited Model 4101 airplanes. This AD was prompted by in-service cracking of the passenger door edge member, seal carrier, and inner skin, adjacent to the roller guide bracket. This AD requires a one-time inspection of the external visible surface of the inner skin, door edge member, and seal carrier adjacent to the roller bracket attachment brackets; and the inner skin, door edge member, and seal carrier at the roller bracket attachment bore, and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 23, 2023.

SUPPLEMENTARY INFORMATION: The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all BAE Systems (Operations) Limited Model 4101 airplanes. The NPRM published in the Federal Register on April 14, 2023 (88 FR 22920). The NPRM was prompted by AD G–2022–0019, dated October 31, 2022, issued by The Civil Aviation Authority (CAA), which is the aviation authority for the United Kingdom (U.K.) (referred to after this as the MCAI). The MCAI states that in-service cracking occurred on the Jetstream 41 passenger door edge member, seal carrier, and inner skin, adjacent to the roller guide bracket. BAE Systems (Operations) Limited reviewed the fatigue test data and existing inspection requirements, and concluded a new inspection is needed to address this potential unsafe condition. In the NPRM, the FAA proposed to require a one-time inspection of the external visible surface of the inner skin, door edge member, and seal carrier adjacent to the roller bracket attachment brackets; and the inner skin, door edge member, and seal carrier at the roller bracket attachment bore, and repair if necessary. The FAA is issuing this AD to address undetected cracking of the E:\FR\FM\19JYR1.SGM 19JYR1 Federal Register / Vol. 88, No. 137 / Wednesday, July 19, 2023 / Rules and Regulations passenger door.

You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–0929. 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. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. 46067 procedures for a one-time eddy current inspection of the external visible surface of the inner skin, door edge member, and seal carrier adjacent to the roller bracket attachment brackets for cracking; a one-time eddy current inspection of the inner skin, door edge member, and seal carrier at the roller bracket attachment bores for cracking; and repair.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
BAE Systems (Operations) Limited Model 4101 airplanes. This AD was 
prompted by in-service cracking of the passenger door edge member, seal 
carrier, and inner skin, adjacent to the roller guide bracket. This AD 
requires a one-time inspection of the external visible surface of the 
inner skin, door edge member, and seal carrier adjacent to the roller 
bracket attachment brackets; and the inner skin, door edge member, and 
seal carrier at the roller bracket attachment bore, and repair if 
necessary. The FAA is issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective August 23, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 23, 
2023.

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all BAE Systems 
(Operations) Limited Model 4101 airplanes. The NPRM published in the 
Federal Register on April 14, 2023 (88 FR 22920). The NPRM was prompted 
by AD G-2022-0019, dated October 31, 2022, issued by The Civil Aviation 
Authority (CAA), which is the aviation authority for the United Kingdom 
(U.K.) (referred to after this as the MCAI). The MCAI states that in-
service cracking occurred on the Jetstream 41 passenger door edge 
member, seal carrier, and inner skin, adjacent to the roller guide 
bracket. BAE Systems (Operations) Limited reviewed the fatigue test 
data and existing inspection requirements, and concluded a new 
inspection is needed to address this potential unsafe condition.
    In the NPRM, the FAA proposed to require a one-time inspection of 
the external visible surface of the inner skin, door edge member, and 
seal carrier adjacent to the roller bracket attachment brackets; and 
the inner skin, door edge member, and seal carrier at the roller 
bracket attachment bore, and repair if necessary. The FAA is issuing 
this AD to address undetected cracking of the

[[Page 46067]]

passenger door. The unsafe condition, if not addressed, could result in 
a partial failure of the passenger door, and consequent reduced 
structural integrity of the passenger door.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0929.

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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed BAe JETSTREAM Series 4100 Service Bulletin J41-52-
065, Revision 1, dated June 8, 2022. This service information specifies 
procedures for a one-time eddy current inspection of the external 
visible surface of the inner skin, door edge member, and seal carrier 
adjacent to the roller bracket attachment brackets for cracking; a one-
time eddy current inspection of the inner skin, door edge member, and 
seal carrier at the roller bracket attachment bores for cracking; and 
repair.
    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 affects 12 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------

    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.
