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

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

1 work-hour × $85 per hour = $85 .......................................................................................................................... $2,500 $2,585 

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.
