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 

July 20, 2023 (88 FR 46702). The NPRM 

was prompted by AD CF–2023–28, 

dated May 4, 2023, issued by Transport 

Canada, which is the aviation authority 

for Canada (Transport Canada AD CF– 

2023–28) (also referred to as the MCAI). 

The MCAI states a deficiency in the 

design of the engine fire extinguishing 

control and indication system was 

discovered. After the loss of one hot 

battery DC bus, the AVAIL legend on 

BTL 1 and BTL 2 push button 

annunciators (PBAs) will not illuminate 

green upon pressing the corresponding 

ENG FIRE PBA. This condition affects 

both L ENG FIRE and R ENG FIRE PBAs 

on the overhead panel. The misleading 

indication given by the AVAIL legend 

on BTL 1 and BTL 2 PBAs will affect the 

crew’s assessment of the situation. The 

crew may hesitate to extinguish an 

engine fire despite having access to a 

functional engine fire extinguishing 

system, or may reselect the FIRE PBA, 

resulting in loss of the ability to isolate 

and extinguish the fire. 

In the NPRM, the FAA proposed to 

require installing a software update to 

the ICCP RDC, as specified in Transport 

Canada AD CF–2023–28. 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–2023–1501. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received one comment from 

Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

The FAA received an additional 

comment from Delta Air Lines (Delta). 

The following presents the comment 

received on the NPRM and the FAA’s 

response. 

Request To Clarify Software 

Installation Requirements 

Delta requested that an additional 

exception be added to paragraph (h) of 

the proposed AD to clarify that it is 

acceptable to use a different method of 

upgrading the software, using Airbus 

Canada Limited Partnership Service 

Bulletin BD500–311001, Issue 001, 

dated March 14, 2023, only as a 

reference. Delta explained that it has a 

different policy for installing software 

that requires the use of a Portable 

Maintenance Access Terminal (PMAT), 

model PMAT2000, instead of a USB 

device. 

The FAA partially agrees with the 

proposed changes. The FAA agrees to 

clarify that the PMAT method is 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 88, No. 192 / Thursday, October 5, 2023 / Rules and Regulations 69019 

permitted, but the FAA will not require 

the use of a specific model of PMAT. 

Also, using the service information as a 

reference must be specified in a note 

rather than in the paragraph itself. 

Therefore, a single paragraph (h)(2) has 

been added to this AD to provide this 

clarification, and a note has been added 

regarding the use of Airbus Canada 

Limited Partnership Service Bulletin 

BD500–311001, Issue 001, dated March 

14, 2023, as a reference. 

Conclusion 

These products have been approved 

by the aviation authority of another 

country and are 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 these 

products. 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. 

Related Service Information Under 1 

CFR Part 51 

Transport Canada AD CF–2023–28 

specifies procedures for installing the 

software update to the ICCP RDC to 

restore the intended functionality of the 

PBA green indications. 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 76 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 6 work-hours × $85 per hour = Up to $510 ..................... Up to $7,500 .................. Up to $8,010 .................. Up to $608,760. 

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. 

List of Subjects in 14 CFR Part 39
