AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Airbus Canada Limited 

Partnership Model BD–500–1A11 

airplanes. This proposed AD was 

prompted by an investigation of an inservice hydraulic fluid leakage event 

that indicated the potential use of an 

uncalibrated torque wrench when 

tightening the union fittings at the 

pressure and return interfaces of all 

three rudder hydraulic power control 

units (PCUs). This proposed AD would 

require properly torquing the rudder 

PCU hydraulic fittings and applying the 

torque seal on the rudder PCU hydraulic 

fittings, as specified in a Transport 

Canada AD, which is proposed for 

incorporation by reference (IBR). The 

FAA is proposing this AD to address the 

unsafe condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by February 3, 

2025.

Background 

Transport Canada, which is the 

aviation authority for Canada, has 

issued Transport Canada AD CF–2024– 

13, dated April 29, 2024 (Transport 

Canada AD CF–2024–13) (also referred 

to as the MCAI), to correct an unsafe 

condition for certain Airbus Canada 

Limited Partnership Model BD–500– 

1A11 airplanes. The MCAI states an 

investigation of an in-service leakage 

event indicated the potential use of an 

uncalibrated torque wrench when 

tightening the union fittings at the 

pressure and return interfaces of all 

three rudder PCUs. If not corrected, this 

condition could cause the union fittings 

to come loose and leak, resulting in the 


ddrumheller on DSK120RN23PROD with PROPOSALS1
104068 Federal Register / Vol. 89, No. 245 / Friday, December 20, 2024 / Proposed Rules 

potential loss of one or more hydraulic 

systems. 

The FAA is proposing 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–2024–2666. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

Transport Canada AD CF–2024–13 

specifies procedures for properly 

torquing the rudder PCU hydraulic 

fittings and applying the torque seal on 

the rudder PCU hydraulic fittings, 

which includes cleaning any leaks at the 

coil B-nut connections, performing a 

visual inspection for hydraulic leaks for 

all rudder PCU coil tube fittings and 

repair. The repair includes tightening 

the nut to the specified torque, testing 

for leakage limits, and replacing any 

defective components. 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. 

FAA’s Determination 

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 

is issuing this NPRM after determining 

that the unsafe condition described 

previously is likely to exist or develop 

in other products of the same type 

design. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

Transport Canada AD CF–2024–13 

described previously, except for any 

differences identified as exceptions in 

the regulatory text of this proposed AD. 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, the FAA proposes to 

incorporate Transport Canada AD CF– 

2024–13 by reference in the FAA final 

rule. This proposed AD would, 

therefore, require compliance with 

Transport Canada AD CF–2024–13 in its 

entirety through that incorporation, 

except for any differences identified as 

exceptions in the regulatory text of this 

proposed AD. Material required by 

Transport Canada AD CF–2024–13 for 

compliance will be available at 

regulations.gov under Docket No. FAA– 

2024–2666 after the FAA final rule is 

published. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 5 

airplanes of U.S. registry. The FAA 

estimates the following costs to comply 

with this proposed AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

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

Up to 9 work-hours × $85 per hour = Up to $765 .......... Up to $0 * ........................... Up to $765 ......................... Up to $3,825. 

* The FAA has received no definitive data on which to base the cost estimates for the replacement cost. 

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 determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would 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 this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

List of Subjects in 14 CFR Part 39
