FOR FURTHER INFORMATION CONTACT: Vladimir Ulyanov, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, E:\FR\FM\12NOR1.SGM 12NOR1 88882 Federal Register / Vol. 89, No. 218 / Tuesday, November 12, 2024 / Rules and Regulations Suite 410, Westbury, NY 11590; telephone 206–231–3229; email vladimir.ulyanov@faa.gov. SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2023–21–02, Amendment 39–22574 (88 FR 76107, November 6, 2023) (AD2023–21–02). AD 2023–21–02 applied to certain Airbus SAS Model 330–201, –202, –203, –223, –223F, –243, –243F, –301, –302, –303, –321, –322, –323, –341, –342, –343, –841 and –941 airplanes. AD 2023–21–02 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2023– 21–02 to address fatigue cracking, accidental damage, and corrosion in principal structural elements; such fatigue cracking, accidental damage, and corrosion could result in reduced structural integrity of the airplane. The NPRM published in the Federal Register on July 24, 2024 (89 FR 59853). The NPRM was prompted by AD 2024– 0011, dated January 10, 2024 (EASA AD 2024–0011) (also referred to as the MCAI), issued by EASA, which is the Technical Agent for the Member States of the European Union. The MCAI states that new or more restrictive airworthiness limitations have been developed. In the NPRM, the FAA proposed to continue to require certain actions in AD 2023–21–02 and to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in EASA AD 2024–0011. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–1894. Discussion of Final Airworthiness Directive Comments khammond on DSKJM1Z7X2PROD with RULES The FAA received a comment from Air Line Pilots Association, International (ALPA), who supported the NPRM without change. 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 VerDate Sep<11>2014 15:54 Nov 08, 2024 Jkt 265001 in the MCAI referenced above. The FAA reviewed the relevant data, considered the comment received, 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. Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2024–0011, dated January 10, 2024, specifies new or more restrictive airworthiness limitations for airplane structures. This AD also requires EASA AD 2022–0187, dated September 13, 2022, and EASA AD 2023–0015, dated January 19, 2023, which the Director of the Federal Register approved for incorporation by reference as of December 11, 2023 (88 FR 76107, November 6, 2023). This material 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 126 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 2023–21–02 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours 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. The FAA estimates the total cost per operator for the new actions to be $7,650 (90 work-hours × $85 per workhour). 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 PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 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 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.

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 Bombardier, Inc., Model BD–100–1A10 airplanes. The NPRM published in the Federal Register on August 9, 2024 (89 FR 65267). The NPRM was prompted by AD CF–2023– 78, dated December 19, 2023, issued by Transport Canada, which is the aviation authority for Canada (also referred to as the MCAI). The MCAI states that airplanes could experience misleading electrical system status indications (push button annunciators (PBA) and engine instrument and crew alerting system (EICAS)) as a result of contamination of electrical contacts in the left-hand (LH) direct current power center (DCPC) internal communication data bus. The MCAI states that new or more restrictive maintenance tasks have been developed to rectify lower time LH DCPC units not addressed by previously issued ADs. In the NPRM, the FAA proposed to require revising the existing PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 maintenance or inspection program, as applicable, to incorporate new or more restrictive maintenance tasks. The FAA is issuing this AD to address erratic indications, which could cause the flightcrew to turn off fully operational electrical power sources, leading to partial or complete loss of electrical power. The unsafe condition, if not addressed, could result in loss of flight displays and reduced controllability of the airplane.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2023-21-
02, which applied to certain Airbus SAS Model A330-200 series, A330-200 
Freighter series, A330-300 series, A330-800 series, and A330-900 series 
airplanes. AD 2023-21-02 required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. This AD was prompted by a 
determination that new or more restrictive airworthiness limitations 
are necessary. This AD continues to require certain actions in AD 2023-
21-02 and requires revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations, as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is incorporated by reference. The FAA is 
issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2023-21-02, Amendment 39-22574 (88 FR 
76107, November 6, 2023) (AD2023-21-02). AD 2023-21-02 applied to 
certain Airbus SAS Model 330-201, -202, -203, -223, -223F, -243, -243F, 
-301, -302, -303, -321, -322, -323, -341, -342, -343, -841 and -941 
airplanes. AD 2023-21-02 required revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. The FAA issued AD 2023-21-02 to 
address fatigue cracking, accidental damage, and corrosion in principal 
structural elements; such fatigue cracking, accidental damage, and 
corrosion could result in reduced structural integrity of the airplane.
    The NPRM published in the Federal Register on July 24, 2024 (89 FR 
59853). The NPRM was prompted by AD 2024-0011, dated January 10, 2024 
(EASA AD 2024-0011) (also referred to as the MCAI), issued by EASA, 
which is the Technical Agent for the Member States of the European 
Union. The MCAI states that new or more restrictive airworthiness 
limitations have been developed.
    In the NPRM, the FAA proposed to continue to require certain 
actions in AD 2023-21-02 and to require revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in EASA AD 
2024-0011. The FAA is issuing this AD to address the unsafe condition 
on these products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-1894.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International (ALPA), who supported the NPRM without change.

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, considered the 
comment received, 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.

Material Incorporated by Reference Under 1 CFR Part 51

    EASA AD 2024-0011, dated January 10, 2024, specifies new or more 
restrictive airworthiness limitations for airplane structures.
    This AD also requires EASA AD 2022-0187, dated September 13, 2022, 
and EASA AD 2023-0015, dated January 19, 2023, which the Director of 
the Federal Register approved for incorporation by reference as of 
December 11, 2023 (88 FR 76107, November 6, 2023).
    This material 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 126 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 2023-21-02 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing 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.
    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

    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.
