ACTION: Final rule. AGENCY: The FAA is superseding Airworthiness Directive (AD) 99–25–11 for certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146– RJ series airplanes. AD 99–25–11 required repetitive inspections for cracks along the face of the retraction attachment boss in the nose landing gear (NLG) sidewall; and corrective action, if necessary. This AD was prompted by a report of a crack found on the left-hand sidewall well on the NLG, and by the determination that additional airplanes are subject to the identified unsafe condition. This AD continues to require the actions in AD 99–25–11, and expands the applicability. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective March 17, 2023. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of March 17, 2023. The Director of the Federal Register approved the incorporation by reference of a certain other publication listed in this AD as of February 1, 2000 (64 FR 72522, December 28, 1999).

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 99–25–11, Amendment 39–11454 (64 FR 72522, December 28, 1999) (AD 99–25–11). AD 99–25–11 applied to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146–RJ series airplanes. AD 99–25–11 required repetitive eddy current inspections for cracks along the face of the retraction attachment boss in the NLG sidewall; and corrective action, if necessary. AD 99–25–11 was prompted by issuance of MCAI by a foreign civil aviation authority. The FAA issued AD 99–25– 11 to address cracking along the face of the retraction attachment boss in the NLG sidewall, which could result in premature extension of the NLG or result in depressurization of the airplane. FAA AD 99–25–11 corresponds to British AD 015–10–98. The NPRM published in the Federal Register on October 31, 2022 (87 FR 65541). The NPRM was prompted by AD G–2021–0016R1, dated February 18, 2022 (U.K. CAA AD G–2021–0016R1) (also referred as the MCAI), issued by the Civil Aviation Authority, which is the aviation authority for the United Kingdom. U.K. CAA AD G–2021– 0016R1 superseded European Union E:\FR\FM\10FER1.SGM 10FER1 8748 Federal Register / Vol. 88, No. 28 / Friday, February 10, 2023 / Rules and Regulations Aviation Safety Agency (EASA) AD 2007–0305, dated December 20, 2007, which superseded British AD 015–10– 98. The FAA did not issue an AD corresponding to EASA AD 2007–0305. The MCAI states that evidence of cracking was found on several in-service airplanes in the bore and along the face of the retraction jack attachment boss on the left-hand NLG sidewall. Undetected cracking of the NLG sidewall could lead to explosive decompression of the fuselage near to the flightcrew (since the NLG sidewall forms part of the nose fuselage pressure shell), leading to significant structural damage to the airframe and/or incapacitation of the flightcrew. The effectivity of each revision of Inspection Service Bulletin ISB.53–152 before Revision 8 was limited to airplanes that were not modified by torque tightening modification HCM01641A in production. BAE Systems (Operations) Limited has received reports of two airplanes with cracks at the NLG retraction jack attachment boss; those airplanes were post-modification HCM01641A and as such were not subject to the requirements of FAA AD 99–25–11. As a result of new findings and further analysis, BAE Systems (Operations) Limited issued Revision 8 of ISB.53– 152, dated February 19, 2018, which extends the effectivity to all BAe 146 and Avro 146–RJ airplanes, except for airplanes post-modification HCM20011A, HCM20012A, HCM20013A, HCM20313A, HCM20314A, or HMC20315A. Revisions prior to Revision 8 of ISB.53–152 included provisions for continued operation with certain crack conditions, which was also allowed in FAA AD 99–25–11 if approved as specified in paragraph (h)(1) of this AD. The U.K. CAA and the FAA have determined that continued operation with known cracks is not acceptable. Therefore, this AD does not allow flight with cracks. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1313. In the NPRM, the FAA proposed to continue to require the actions in AD 99–25–11 and expand the applicability. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs. 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 Systems (Operations) Limited Inspection Service Bulletin ISB.53–152, Revision 8, dated February 19, 2018. This service information describes procedures for repetitive eddy current inspections for cracking in the bore and along the face of the retraction attachment boss in the left-hand NLG sidewall, and repair or replacement of a cracked sidewall. The FAA also reviewed British Aerospace Service Bulletin SB.53–152, dated October 8, 1998, which the Director of the Federal Register approved for incorporation by reference as of February 1, 2000 (64 FR 72522, December 28, 1999). 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 ADDRESSES. Costs of Compliance The FAA estimates that this AD affects 20 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Retained actions from AD 99– 25–11. New proposed actions ........... 1 work-hour × $85 per hour = $85 per inspection cycle. 2 work-hours × $85 per hour = $170. The FAA has received no definitive data on which to base the cost estimates for the on-condition actions specified in this AD. lotter on DSK11XQN23PROD with RULES1 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 VerDate Sep<11>2014 15:43 Feb 09, 2023 Jkt 259001 Parts cost Cost per product $0 $85 per inspection cycle ........ $1,700 per inspection cycle. 0 170 per inspection cycle ........ 3,400 per inspection cycle. 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 has 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 PO 00000 Frm 00020 Fmt 4700 Cost on U.S. operators Sfmt 4700 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.

Airworthiness Directives; BAE Systems (Operations) Limited 
Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 99-25-11 
for certain BAE Systems (Operations) Limited Model BAe 146 and Avro 
146-RJ series airplanes. AD 99-25-11 required repetitive inspections 
for cracks along the face of the retraction attachment boss in the nose 
landing gear (NLG) sidewall; and corrective action, if necessary. This 
AD was prompted by a report of a crack found on the left-hand sidewall 
well on the NLG, and by the determination that additional airplanes are 
subject to the identified unsafe condition. This AD continues to 
require the actions in AD 99-25-11, and expands the applicability. The 
FAA is issuing this AD to address the unsafe condition on these 
products.

DATES: This AD is effective March 17, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 17, 
2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
February 1, 2000 (64 FR 72522, December 28, 1999).

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2022-1313; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 99-25-11, Amendment 39-11454 (64 FR 72522, 
December 28, 1999) (AD 99-25-11). AD 99-25-11 applied to certain BAE 
Systems (Operations) Limited Model BAe 146 and Avro 146-RJ series 
airplanes. AD 99-25-11 required repetitive eddy current inspections for 
cracks along the face of the retraction attachment boss in the NLG 
sidewall; and corrective action, if necessary. AD 99-25-11 was prompted 
by issuance of MCAI by a foreign civil aviation authority. The FAA 
issued AD 99-25-11 to address cracking along the face of the retraction 
attachment boss in the NLG sidewall, which could result in premature 
extension of the NLG or result in depressurization of the airplane.
    FAA AD 99-25-11 corresponds to British AD 015-10-98.
    The NPRM published in the Federal Register on October 31, 2022 (87 
FR 65541). The NPRM was prompted by AD G-2021-0016R1, dated February 
18, 2022 (U.K. CAA AD G-2021-0016R1) (also referred as the MCAI), 
issued by the Civil Aviation Authority, which is the aviation authority 
for the United Kingdom. U.K. CAA AD G-2021-0016R1 superseded European 
Union

[[Page 8748]]

Aviation Safety Agency (EASA) AD 2007-0305, dated December 20, 2007, 
which superseded British AD 015-10-98. The FAA did not issue an AD 
corresponding to EASA AD 2007-0305. The MCAI states that evidence of 
cracking was found on several in-service airplanes in the bore and 
along the face of the retraction jack attachment boss on the left-hand 
NLG sidewall. Undetected cracking of the NLG sidewall could lead to 
explosive decompression of the fuselage near to the flightcrew (since 
the NLG sidewall forms part of the nose fuselage pressure shell), 
leading to significant structural damage to the airframe and/or 
incapacitation of the flightcrew.
    The effectivity of each revision of Inspection Service Bulletin 
ISB.53-152 before Revision 8 was limited to airplanes that were not 
modified by torque tightening modification HCM01641A in production. BAE 
Systems (Operations) Limited has received reports of two airplanes with 
cracks at the NLG retraction jack attachment boss; those airplanes were 
post-modification HCM01641A and as such were not subject to the 
requirements of FAA AD 99-25-11. As a result of new findings and 
further analysis, BAE Systems (Operations) Limited issued Revision 8 of 
ISB.53-152, dated February 19, 2018, which extends the effectivity to 
all BAe 146 and Avro 146-RJ airplanes, except for airplanes post-
modification HCM20011A, HCM20012A, HCM20013A, HCM20313A, HCM20314A, or 
HMC20315A.
    Revisions prior to Revision 8 of ISB.53-152 included provisions for 
continued operation with certain crack conditions, which was also 
allowed in FAA AD 99-25-11 if approved as specified in paragraph (h)(1) 
of this AD. The U.K. CAA and the FAA have determined that continued 
operation with known cracks is not acceptable. Therefore, this AD does 
not allow flight with cracks.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1313.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 99-25-11 and expand the applicability.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the costs.

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 Systems (Operations) Limited Inspection 
Service Bulletin ISB.53-152, Revision 8, dated February 19, 2018. This 
service information describes procedures for repetitive eddy current 
inspections for cracking in the bore and along the face of the 
retraction attachment boss in the left-hand NLG sidewall, and repair or 
replacement of a cracked sidewall.
    The FAA also reviewed British Aerospace Service Bulletin SB.53-152, 
dated October 8, 1998, which the Director of the Federal Register 
approved for incorporation by reference as of February 1, 2000 (64 FR 
72522, December 28, 1999).
    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 ADDRESSES.

Costs of Compliance

    The FAA estimates that this AD affects 20 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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 has 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.
