You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2023–1997. 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.

Transport Canada AD CF–2023–15 specifies using specific AMP issues for electrical rigging procedures for primary flight control surfaces, and, for certain airplanes, performing an electrical rigging confirmation check of primary flight control surfaces. 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 ADDRESSES. 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 72009 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– 2023–15 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with Transport Canada AD CF–2023–15 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information required by Transport Canada AD CF– 2023–15 for compliance will be available at regulations.gov under Docket No. FAA–2023–1997 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 72 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 Up to 9 work-hours × $85 per hour = $765 .......................... lotter on DSK11XQN23PROD with PROPOSALS1 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.

Certificate Previously Held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-
1A11 airplanes. This proposed AD was prompted by the determination that 
reliance on DAL D software for flight critical fly-by-wire (FBW) 
rigging functions may result in undetected inaccurate positioning of 
the primary flight control surfaces. This proposed AD would require the 
use of specific issues of the aircraft maintenance publication (AMP) 
for electrical rigging procedures, and an electrical rigging 
confirmation check of primary flight control surfaces for certain 
airplanes, 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 December 4, 
2023.

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued Transport Canada AD CF-2023-15, dated March 2, 2023 (Transport 
Canada AD CF-2023-15) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus Canada Limited Partnership Model BD-
500-1A10 and BD-500-1A11 airplanes. The MCAI states that during the 
airplane design review, it was discovered that the FBW electrical 
rigging functions rely in part on the primary flight control computer 
maintenance partition certified to design assurance level (DAL) D. The 
reliance on DAL D software for flight critical FBW rigging functions 
may result in undetected inaccurate

positioning of the primary flight control surfaces.
    The FAA is issuing this AD to ensure accurate rigging of the 
aircraft primary flight control surfaces. Undetected inaccurate 
positioning of the primary flight control surfaces, in combination with 
an additional failure or extreme maneuvers, can lead to runway 
excursion or exceedance of the structure ultimate load.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-1997.

Related Service Information Under 1 CFR Part 51

    Transport Canada AD CF-2023-15 specifies using specific AMP issues 
for electrical rigging procedures for primary flight control surfaces, 
and, for certain airplanes, performing an electrical rigging 
confirmation check of primary flight control surfaces.
    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 ADDRESSES.

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-2023-15 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-2023-15 by reference 
in the FAA final rule. This proposed AD would, therefore, require 
compliance with Transport Canada AD CF-2023-15 in its entirety through 
that incorporation, except for any differences identified as exceptions 
in the regulatory text of this proposed AD. Service information 
required by Transport Canada AD CF-2023-15 for compliance will be 
available at regulations.gov under Docket No. FAA-2023-1997 after the 
FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 72 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 x $85 per hour =                     $0  Up to $765...............  Up to $55,080.
 $765.
----------------------------------------------------------------------------------------------------------------

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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Airbus Canada Limited Partnership (Type Certificate Previously Held 
by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.): 
Docket No. FAA-2023-1997; Project Identifier MCAI-2023-00383-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by December 4, 2023.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Airbus Canada Limited Partnership (Type 
Certificate previously held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 
airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

[[Page 72010]]

(e) Unsafe Condition

    It is possible that the surface travel checks were not done 
after the electrical rigging of the ailerons, the elevators, and the 
rudder. If this occurs, it is possible that the ailerons, the 
elevators, and the rudder will not be able to reach their maximum 
travel or return to their neutral position. The FAA is issuing this 
AD to ensure accurate rigging of the aircraft primary flight control 
surfaces by adding physical travel and centering checks of primary 
flight control surfaces. The unsafe condition, if not addressed, 
could result in undetected inaccurate positioning of the primary 
flight control surfaces which in combination with an additional 
failure or extreme maneuvers can lead to runway excursion or 
structure ultimate load exceedance.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, Transport Canada AD CF-2023-15, dated March 2, 2023 
(Transport Canada AD CF-2023-15).

(h) Exception to Transport Canada AD CF-2023-15

    In Transport Canada AD CF-2023-15, instead of using the 
compliance time specified in Part II, comply with Part II at the 
later of the times specified in paragraphs (h)(1) and (2) of this 
AD.
    (1) For airplanes on which the actions specified in Airbus 
Canada Limited Partnership A220 Service Bulletin BD500-270016 have 
not been done before the effective date of this AD: Within 930 
flight hours after the effective date of this AD.
    (2) For airplanes on which the actions specified in Airbus 
Canada Limited Partnership A220 Service Bulletin BD500-270016 have 
been done before the effective date of this AD: Within 4,900 flight 
hours after accomplishment of the actions specified in Airbus Canada 
Limited Partnership A220 Service Bulletin BD500-270016, or within 
930 flight hours after the effective date of this AD, whichever 
occurs later.
