(d) Subject 

Air Transport Association (ATA) of 

America Code 24, Electrical Power. 

(e) Unsafe Condition 

This AD was prompted by a report that 

some Model 767–300 series airplanes that 

have been modified to operate in a freighter 

configuration are missing an electrical 

bracket for a wire bundle in the main 

equipment center, which affects wire 

separation configuration requirements for 

fuel quantity indicating system wiring and 

could result in an electrical fault condition. 

The FAA is issuing this AD to prevent 

possible ignition sources in the fuel tank due 

to an electrical fault, which, in combination 

with flammable fuel vapors, could result in 

a fuel tank explosion and consequent loss of 

the airplane. 

(f) Compliance

the provisions of paragraphs (j)(4)(i) and (ii) 

of this AD apply. 

(i) The steps labeled as RC, including 

substeps under an RC step and any figures 

identified in an RC step, must be done to 

comply with the AD. If a step or substep is 

labeled ‘‘RC Exempt,’’ then the RC 

requirement is removed from that step or 

substep. An AMOC is required for any 

deviations to RC steps, including substeps 

and identified figures. 

(ii) Steps not labeled as RC may be 

deviated from using accepted methods in 

accordance with the operator’s maintenance 

or inspection program without obtaining 

approval of an AMOC, provided the RC steps,

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 6, 2024 (89 FR 37144). The NPRM 

was prompted by AD CF–2023–67, 

dated October 4, 2023, issued by 

Transport Canada, which is the aviation 

authority for Canada (Transport Canada 

AD CF 2023–67) (also referred to as the 

MCAI). The MCAI states that at lavatory 

and galley locations within the airplane, 

incorrect terminal lugs have been 

installed which are not compatible with 

the associated wire gauge. 

In the NPRM, the FAA proposed to 

require removing and replacing existing 

lug terminals at various lavatory and 

galley locations, as specified in 

Transport Canada AD CF–2023–67. The 

FAA is issuing this AD to address 

incorrect terminal lugs that may become 

loose causing a loss of electromagnetic 

interference protection, which could 

result in false alarms of the lavatory 

smoke detectors, false alarms of low 

crew oxygen pressure, loss of automatic 

control of automatic cabin temperature 

control, and loss of lavatory flush. The 

unsafe condition, if not corrected, could 

result in an increase in crew workload, 

including diversions and descent to 

below 10,000 feet or the lowest safe 

altitude. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–1289. 

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 an individual, who 

requested to be informed as to how the 

FAA will continue coordination 

between the FAA and Transport Canada 

to ensure the effectiveness of the AD, 

and to address any emerging issues 

related to the replacement of terminal 

lugs. 

The FAA continuously evaluates 

operator and manufacturer reports and 

other data to promote safe type 

certification and production. Since this 

commenter did not ask for a change to 

the final rule, no change has been made 

to this AD in response to this request. 

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, 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 

Transport Canada AD CF–2023–67 

specifies procedures for removing 

existing terminal lugs and installing 

new terminal lugs at lavatories A, C1, 

C2, C3, D2, D4, and E, and galleys G2A, 

G2G, and G4, including replacing the 

ground wires for new terminal lugs if 

the ground wire length is not sufficient; 

and installing the service bulletin 

incorporation placards. 

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 66 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per product Cost on U.S. operators 

Up to 81 work-hours × $85 per hour = Up to $6,885 ..................... (*) Up to $6,885 .......... Up to $454,410. 

* The FAA has received no definitive data on which to base the cost estimates for the parts specified in this AD. 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected operators. 

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.
