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 Thales AVS France SAS (Thales) 

flight management computer navigation 

modules (FMC2 NAVM) installed on, 

but not limited to, airplanes. This AD 

was prompted by reports that, due to 

software issues, certain FMC2 NAVM 

navigation modules provide erroneous 

data to the flight management computer, 

compromising safe flight of the airplane. 

This proposed AD would require 

revising the existing aircraft flight 

manual (AFM) for your airplane and 

updating the navigation database. This 

proposed AD would also prohibit 

installing a database unless certain 

procedures were removed. The FAA is 

proposing this AD to address the unsafe 

condition on these products.

Background 

The European Union Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2022–0024, dated February 4, 2022 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for Thales 

FMC2 NAVM, part number (P/N) 

C13084CA03, installed on, but not 

limited to Dassault (formerly Bre ́guet) 

Br.1150 Atlantique 2 (ATL2) maritime 

patrol airplanes. The MCAI states that 

Thales FMC2 NAVM, P/N C13084CA03, 

provides erroneous guidance for 

navigation procedures of the flight 

management system due to issues with 

the software. This condition, if not 

addressed, could compromise the safety 

margins of the airplane. To address the 

unsafe condition, the MCAI requires 

revising the AFM with operational 

instructions for the affected airborne 

navigation procedures of the AFM. The 

MCAI also requires updating the 

navigation database software, and 

prohibits installing a database for the 

Thales FMC2 NAVM, P/N C13084CA03, 

unless it does not include the 

procedures specified in section II of 

Thales Service Information Letter 

F9111–J70859DN–00, issued January 18, 

2022 (Thales SIL F9111–J70859DN–00). 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1716. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Thales SIL F9111– 

J70859DN–00. This service information 

specifies updating the Thales FMC2 

NAVM, P/N C13084CA03, navigation 

database. 

This service information 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 

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 and service 

information referenced above. The FAA 

is issuing this AD after determining the 

unsafe condition 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 

revising the existing AFM for your 

airplane and updating the navigation 

database. This proposed AD would also 

prohibit installing a database for the 

Thales FMC2 NAVM, P/N C13084CA03, 

unless it does not include the 

procedures specified in section II of 

Thales SIL F9111–J70859DN–00. 

The owner/operator (pilot) holding at 

least a private pilot certificate may 

perform the proposed incorporation of 

the operating limitation into the existing 

AFM of your airplane, and the actions 

must be entered into the aircraft records 

showing compliance with this AD in 

accordance with 14 CFR 43.9(a) and 

91.417(a)(2)(v). The record must be 

maintained as required by 14 CFR 

91.417, 121.380, or 135.439. The 

proposed incorporation of the operating 

limitation into the existing AFM of your 

airplane is not considered a 

maintenance action and may be done 

equally by a pilot or a mechanic. This 

is an exception to the FAA’s standard 

maintenance regulations. 

Differences Between This Proposed AD 

and the MCAI 

The MCAI applies to all Thales FMC2 

NAVMs, P/N C13084CA03, installed on, 

but not limited to Dassault (formerly 

Bre ́guet) Br.1150 Atlantique 2 (ATL2) 

maritime patrol airplanes, and this 

proposed AD would not apply to those 

airplanes because those airplanes do not 

have an FAA type certificate. Currently, 

no airplanes on the U.S. registry 

incorporate the navigation equipment 

affected by this AD. 

Costs of Compliance 

There are currently no affected 

airplanes on the U.S. registry with a 

Thales FMC2 NAVM, P/N C13084CA03, 

installed. In the event a U.S.-registered 

airplane would have this equipment 

installed, the following is an estimate of 

the costs to comply with this proposed 

AD. 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Revise AFM and update navigation database 2 work-hours × $85 per hour = $170 ............. $0 $170 $0 

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 


lotter on DSK11XQN23PROD with PROPOSALS1
57906 Federal Register / Vol. 88, No. 163 / Thursday, August 24, 2023 / Proposed Rules 

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 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety.

Except for Confidential Business

received, without change, to

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this NPRM 

contain commercial or financial 

information that is customarily treated 

as private, that you actually treat as 

private, and that is relevant or 

responsive to this NPRM, it is important 

that you clearly designate the submitted 

comments as CBI. Please mark each 

page of your submission containing CBI 

as ‘‘PROPIN.’’ The FAA will treat such 

marked submissions as confidential 

under the FOIA, and they will not be 

placed in the public docket of this 

NPRM. Submissions containing CBI 

should be sent to Jim Rutherford, 

Aviation Safety Engineer, FAA, 1600 

Stewart Avenue, Suite 410, Westbury, 

NY 11590. Any commentary that the 

FAA receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking.
