Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2022-25-51, which applies to all Airbus Canada Limited Partnership Model BD-500-1A10 and Model BD-500-1A11 airplanes. AD 2022-25-51 requires revising the Limitations section of the existing airplane flight manual (AFM) to include a new warning and a new limitation. Since the FAA issued AD 2022-25-51, updated primary flight control computer (PFCC) software has been developed to address the unsafe condition. This proposed AD would continue to require the actions in AD 2022-25-51, require installing the updated PFCC software, which terminates the AFM revision, and remove airplanes from the applicability, 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.

-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2022-25-51, which applies to all Airbus Canada Limited Partnership
Model BD-500-1A10 and Model BD-500-1A11 airplanes. AD 2022-25-51
requires revising the Limitations section of the existing airplane
flight manual (AFM) to include a new warning and a new limitation.
Since the FAA issued AD 2022-25-51, updated primary flight control
computer (PFCC) software has been developed to address the unsafe
condition. This proposed AD would continue to require the actions in AD
2022-25-51, require installing the updated PFCC software, which
terminates the AFM revision, and remove airplanes from the
applicability, 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 May 2,
2025.

Background
The FAA issued AD 2022-25-51, Amendment 39-22282 (87 FR 75911,
December 12, 2022) (AD 2022-25-51), for all Airbus Canada Limited
Partnership Model BD-500-1A10 and Model BD-500-1A11 airplanes. AD 2022-
25-51 was prompted by an MCAI originated by Transport Canada, which is
the aviation authority for Canada. Transport Canada issued Transport
Canada Emergency AD CF-2022-64, dated November 17, 2022 (Transport
Canada Emergency AD CF-2022-64), to correct an unsafe condition.
AD 2022-25-51 requires revising the Limitations section of the
existing AFM by revising the title of the existing autopilot AFM
limitation, including a new warning prior to the existing
[[Page 12499]]
autopilot engagement limitations, and a new limitation prohibiting
selecting or reselecting autothrottle during takeoff after thrust
levers are advanced to the takeoff setting after the existing autopilot
engagement limitations. The FAA issued AD 2022-25-51 to address
inadvertent engagement of the autopilot below 400 feet above ground
level (AGL) when the flightcrew attempts to engage autothrottle. The
unsafe condition, if not addressed, could result in premature rotation
due to inadvertent autopilot engagement, possibly leading to tail-
strike, inability to climb, and loss of control of the airplane.
Actions Since AD 2022-25-51 Was Issued
The preamble to AD 2022-25-51 explained that the FAA considered the
requirements ``interim action'' and was considering further rulemaking.
The FAA has now determined that further rulemaking is indeed necessary,
and this proposed AD follows from that determination.
Since the FAA issued AD 2022-25-51, Transport Canada superseded
Transport Canada Emergency AD CF-2022-64, dated November 17, 2022, and
issued Transport Canada AD CF-2024-36, dated October 22, 2024
(Transport Canada AD CF-2024-36) (also referred to as the MCAI), to
correct an unsafe condition for certain Airbus Canada Limited
Partnership Model BD-500-1A10 and Model BD-500-1A11 airplanes. The MCAI
states that there have been multiple in-service reports associated with
PFCC software deficiencies leading to nuisance messages on the engine-
indicating and crew-alerting system (EICAS) such as rudder fail,
aileron fail, and spoiler fail, and flight control fault due to
erroneous transmissions from the remote electronic unit (REU).
Investigations also indicated design deficiencies in the PFCC software
such as an incorrectly implemented built-in test, which is unable to
detect a failed REU internal hold-up capacitor, or non-implemented
self-tests and monitoring mechanisms to prevent erroneous computations
to be transmitted to consumers. Other in-service events indicated a
lack of software robustness, which may not prevent an un-annunciated
deployment of ground spoilers or an inadvertent autopilot engagement
during the take-off roll. These deficiencies and lack of PFCC software
robustness, if not corrected, could lead to increased flightcrew
workload as well as a large reduction of safety margins. Additionally,
during specific flight phases or in combination with other failures,
these conditions could lead to loss of control of the airplane.
The updated software installation required by this proposed AD
addresses the unsafe condition identified in AD 2022-25-51 and
terminates the AFM revision required by that AD.
The FAA is proposing this AD to address the unsafe condition on
these products. You may examine the MCAI in the AD docket at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2025-0344.
Material Incorporated by Reference Under 1 CFR Part 51
Transport Canada AD CF-2024-36 specifies procedures for revising
the Limitations section of the existing AFM to include a new warning,
installation of updated PFCC software part number 810-0337-009 on three
the PFCCs, which terminates the AFM revision, and applicable concurrent
software updates. 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 retain all requirements of AD 2022-25-51.
This proposed AD would remove airplanes from the applicability because
the software installation, which terminates the AFM revision, was done
in production on Model BD-500-1A10 airplanes having serial numbers (S/
Ns) 50079 and subsequent and on Model BD-500-1A11 airplanes having S/Ns
55298 and subsequent; therefore, the unsafe condition has been
addressed on those airplanes. This proposed AD would require
accomplishing the actions specified in Transport Canada AD CF-2024-36
described previously, except for any differences identified as
exceptions in the regulatory text of this proposed AD and except as
discussed under ``Differences Between This NPRM and the MCAI.'' The
installation of updated PFCC software would terminate the AFM revision
required by paragraph (g) 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-2024-36 by reference
in the FAA final rule. This proposed AD would, therefore, require
compliance with Part II of Transport Canada AD CF-2024-36 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-2024-36 for compliance will be available at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2025-0344 after the FAA final rule
is published.
Differences Between This NPRM and the MCAI
Transport Canada AD CF-2024-36 refers to the Accomplishment
Instructions of Airbus Canada Limited Partnership (ACLP) Service
Bulletin BD500-270022, Issue 001, dated July 25, 2024, for
accomplishing the software installation. The ``Concurrent
Requirements'' paragraph of ACLP Service Bulletin BD500-270022, Issue
001, dated July 25, 2024, refers to ``ACLP Service Bulletin BD500-
270020'' as an additional requirement for certain airplanes; however,
``ACLP Service Bulletin BD500-270020'' is not included in the
Accomplishment Instructions of ACLP Service Bulletin BD500-270022,
Issue 001, dated July 25, 2024.
The FAA has determined the concurrent service bulletin must be done
to address the unsafe condition. The FAA has issued AD 2023-12-09,
Amendment 39-22467 (88 FR 42606, July 3, 2023) (AD 2023-12-09), which
mandates Transport Canada AD CF-2022-65, dated November 23, 2022, and
refers to ACLP Service Bulletin BD500-270020, Issue 001, dated
September 28, 2022 (or later revisions), for software installation.
The FAA has added paragraph (i)(3) of the proposed AD to mandate
the concurrent requirement and clarify applicable compliance times.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 133
[[Page 12500]]
airplanes of U.S. registry. The FAA estimates the following costs to
comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Retained actions from AD 1 work-hour x $85 $0................ $85............... $11,305.
2022[dash]25[dash]51. per hour = $85.
New proposed actions............ Up to 5 work-hours Up to $10,000..... Up to $10,425..... Up to $1,386,525.
x $85 per hour =
$425.
----------------------------------------------------------------------------------------------------------------
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.

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(f), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by:
0

(87 FR 75911, December 12, 2022); and
0
b. Adding the following new AD:
Airbus Canada Limited Partnership (Type Certificate Previously Held
by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.):
Docket No. FAA-2025-0344; Project Identifier MCAI-2024-00638-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by May 2, 2025.
(b) Affected ADs
This AD replaces AD 2022-25-51, Amendment 39-22282 (87 FR 75911,
December 12, 2022) (AD 2022-25-51).
(c) Applicability
This AD applies to Airbus Canada Limited Partnership (type
certificate previously held by C Series Aircraft Limited Partnership
(CSALP); Bombardier, Inc.) Model BD-500-1A10 and Model BD-500-1A11
airplanes, certificated in any category, as identified in Transport
Canada AD CF-2024-36, dated October 22, 2024 (Transport Canada AD
CF-2024-36).
(d) Subject
Air Transport Association (ATA) of America Code 22, Autoflight.
(e) Unsafe Condition
This AD was prompted by multiple in-service reports associated
with primary flight control computer (PFCC) software deficiencies
leading to nuisance messages on the engine-indicating and crew-
alerting system (EICAS) due to erroneous transmissions from the
remote electronic unit (REU). Investigations also indicated design
deficiencies in the PFCC software and a lack of software robustness,
which may not prevent an un-annunciated deployment of ground
spoilers or an inadvertent autopilot engagement during the take-off
roll. The FAA is issuing this AD to address the PFCC software
deficiencies leading to nuisance messages and the lack of PFCC
software robustness. The unsafe condition, if not addressed, could
lead to increased flightcrew workload as well as a large reduction
of safety margins. Additionally, during specific flight phases or in
combination with other failures, these conditions could lead to loss
of control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Revision of Existing AFM, With No Changes
This paragraph restates the requirements of paragraph (g) of AD
2022-25-51, with no changes. Within 7 days after December 27, 2022
(the effective date of AD 2022-25-51), revise the Limitations
section of the existing airplane flight manual (AFM) to include the
information specified in figure 1 to paragraph (g) of this AD. This
may be accomplished by inserting a copy of figure 1 to paragraph (g)
of this AD into the existing AFM. Using an AFM revision that
includes information identical to that in figure 1 to paragraph (g)
of this AD is acceptable for compliance with the requirement of this
paragraph.
