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 certain Airbus Canada Limited Partnership Model BD–500–1A10 and BD–500–1A11 airplanes. The NPRM published in the Federal Register on May 23, 2024 (89 FR 45610). The NPRM was prompted by AD CF–2023–64, dated September 18, 2023, issued by Transport Canada, which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that reports have been received indicating that the pylon-to-wing area motive flow flexible fuel line assemblies may have been installed incorrectly, potentially resulting in a twist to the motive flow fuel line. In the NPRM, the FAA proposed to require inspecting the motive flow fuel line assemblies and corrective actions, as specified in Transport Canada AD CF–2023–64. The FAA is issuing this AD to address a possible abrasion of the fuel line causing a fuel leak; if not addressed, the electrical harness connectors in the wing area could be a potential ignition source and pose a risk of fire. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–1474. Discussion of Final Airworthiness Directive Comments The FAA received a comment from Air Line Pilots Association, International (ALPA), who supported the NPRM without change. PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 The FAA received an additional comment from Delta Airlines. The following presents the comment received on the NPRM and the FAA’s response to the comment. Request for Change to Exceptions Paragraph Delta requested revising paragraph (h)(3) by removing the word ‘‘flexible’’ and revising certain punctuation. Delta stated the term ‘‘flexible’’ is used only when referring to the flexible-hose assembly installed in the shroud assembly. Therefore, the flexible-hose assembly and the shroud assembly are subassemblies of the fuel motive-flow tube assembly. The FAA agrees that the term ‘‘flexible’’ should be removed in reference to the entire motive flow fuel line assemblies since the service information referenced in Transport Canada AD CF–2023–64 requires replacement of the fuel motive-flow tube assembly if damage is found on either the flexible-hose assembly or the shroud assembly. 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 comments 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, and any other changes described previously, 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 The FAA reviewed AD CF–2023–64, dated September 18, 2023. This material specifies procedures for a general visual inspection of the left and right motive flow flexible fuel line assemblies for twisted or damaged fuel lines or damaged shrouds, and replacement of motive flow fuel line assemblies with twisted or damaged fuel lines or damaged shrouds. 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.

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 certain Airbus Canada 
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The 
NPRM published in the Federal Register on May 23, 2024 (89 FR 45610). 
The NPRM was prompted by AD CF-2023-64, dated September 18, 2023, 
issued by Transport Canada, which is the aviation authority for Canada 
(referred to after this as the MCAI). The MCAI states that reports have 
been received indicating that the pylon-to-wing area motive flow 
flexible fuel line assemblies may have been installed incorrectly, 
potentially resulting in a twist to the motive flow fuel line.
    In the NPRM, the FAA proposed to require inspecting the motive flow 
fuel line assemblies and corrective actions, as specified in Transport 
Canada AD CF-2023-64. The FAA is issuing this AD to address a possible 
abrasion of the fuel line causing a fuel leak; if not addressed, the 
electrical harness connectors in the wing area could be a potential 
ignition source and pose a risk of fire.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-1474.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International (ALPA), who supported the NPRM without change.
    The FAA received an additional comment from Delta Airlines. The 
following presents the comment received on the NPRM and the FAA's 
response to the comment.

Request for Change to Exceptions Paragraph

    Delta requested revising paragraph (h)(3) by removing the word 
``flexible'' and revising certain punctuation. Delta stated the term 
``flexible'' is used only when referring to the flexible-hose assembly 
installed in the shroud assembly. Therefore, the flexible-hose assembly 
and the shroud assembly are subassemblies of the fuel motive-flow tube 
assembly.
    The FAA agrees that the term ``flexible'' should be removed in 
reference to the entire motive flow fuel line assemblies since the 
service information referenced in Transport Canada AD CF-2023-64 
requires replacement of the fuel motive-flow tube assembly if damage is 
found on either the flexible-hose assembly or the shroud assembly.

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 
comments 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, and any other changes described previously, 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

    The FAA reviewed AD CF-2023-64, dated September 18, 2023. This 
material specifies procedures for a general visual inspection of the 
left and right motive flow flexible fuel line assemblies for twisted or 
damaged fuel lines or damaged shrouds, and replacement of motive flow 
fuel line assemblies with twisted or damaged fuel lines or damaged 
shrouds.
    This material is reasonably available because the interested 
parties have access to it through their normal course of business or by

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.

incorrectly. The FAA is issuing this AD to ensure the motive flow 
flexible fuel line assemblies are installed correctly. The unsafe 
condition, if not addressed, could result in abrasion of the fuel 
line and a possible fuel leak; as a result, the electrical harness 
connectors in the wing area could be a potential ignition source and 
pose a risk of fire.

unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, Transport Canada AD CF-2023-64.

(h) Exception to Transport Canada AD CF-2023-64

    (1) Where Transport Canada AD CF-2023-64 refers to its effective 
date, this AD requires using the effective date of this AD.
    (2) Where Transport Canada AD CF-2023-64 refers to hours air 
time, this AD requires using flight hours.
    (3) Where the Corrective Actions paragraph of Transport Canada 
AD CF-2023-64 specifies to ``Inspect and, if necessary, replace the 
left and right motive flow fuel line assemblies,'' for this AD, 
replace that text with ``Inspect and, as applicable, replace the 
left and right motive flow fuel line assemblies.''
