Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2022-25-05, which applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2022-25-05 requires repetitive cleaning and greasing of all slat tracks to prevent damage or corrosion; doing repetitive inspections of the slat tracks for any damage or corrosion, and the correct application of grease; and applicable corrective actions. Since the FAA issued AD 2022-25-05, it has been discovered that previous slat track repairs required the use of inappropriate non-destructive test (NDT) methods and, therefore, may have allowed cracks to remain undetected on slat tracks that were previously repaired. This proposed AD would continue to require the actions in AD 2022-25-05 and would require a rework NDT inspection on all slat tracks previously repaired using an inappropriate NDT method. The FAA is proposing this AD to address the unsafe condition on these products.

ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2022-25-05, which applies to certain Airbus Canada Limited Partnership
Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2022-25-05 requires
repetitive cleaning and greasing of all slat tracks to prevent damage
or corrosion; doing repetitive inspections of the slat tracks for any
damage or corrosion, and the correct application of grease; and
applicable corrective actions. Since the FAA issued AD 2022-25-05, it
has been discovered that previous slat track repairs required the use
of inappropriate non-destructive test (NDT) methods and, therefore, may
have allowed cracks to remain undetected on slat tracks that were
previously repaired. This proposed AD would continue to require the
actions in AD 2022-25-05 and would require a rework NDT inspection on
all slat tracks previously repaired using an inappropriate NDT method.
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 June 26,
2026.
ADDRESSES: You may send comments, using the procedures found in 14 CFR

Background
The FAA issued AD 2022-25-05, Amendment 39-22261 (87 FR 77487,
December 19, 2022) (AD 2022-25-05),
[[Page 25810]]
for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-
500-1A11 airplanes. AD 2022-25-05 was prompted by an MCAI originated by
Transport Canada, which is the aviation authority for Canada. Transport
Canada issued AD CF-2021-43, dated November 29, 2021 (Transport Canada
AD CF-2021-43), to correct an unsafe condition.
AD 2022-25-05 requires repetitive cleaning and greasing of all slat
tracks to prevent damage or corrosion; doing repetitive inspections of
the slat tracks for any damage or corrosion, and the correct
application of grease; and applicable corrective actions. The FAA
issued AD 2022-25-05 to address corrosion and wear on the slat tracks,
which could lead to loss of one or more slat panels or loss of slat
track guidance and, consequently, cause catastrophic structural damage
to the wings or other parts of the airplane due to slat panels
departing from the airplane.
Actions Since AD 2022-25-05 Was Issued
Since the FAA issued AD 2022-25-05, Transport Canada superseded
Transport Canada AD CF-2021-43 and issued Transport Canada AD CF-2024-
26, dated July 17, 2024 (Transport Canada AD CF-2024-26), and then
superseded Transport Canada AD CF-2024-26 and issued Transport Canada
AD CF-2025-61, dated November 24, 2025 (Transport Canada AD CF-2025-61)
(also referred to as the MCAI), to correct an unsafe condition for
certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-
1A11 airplanes. The MCAI states that since Transport Canada AD CF-2021-
43 was issued, it has been discovered that previous slat track repairs
required the use of inappropriate NDT methods and, therefore, may have
allowed cracks to remain undetected on slat tracks that were previously
repaired. The MCAI states that reports have been received that the
accomplishment instructions in the referenced service bulletin are
ambiguous and that access constraints prevent the accomplishment of the
service bulletin without the removal of all slat tracks from the
airplane. The MCAI also states that since AD CF-2021-43 was issued, the
manufacturer has revised the service information to specify procedures
for a rework NDT inspection on all slat tracks that were previously
repaired using an inappropriate NDT method, clarify the accomplishment
instructions, and limit the repeat inspection and greasing of all slat
tracks to visible portions of the slat tracks only.
Since Transport Canada AD CF-2024-26 was issued, Transport Canada
has determined that the compliance times in Transport Canada AD CF-
2024-26 need to be updated. The MCAI maintains the requirements of
Transport Canada AD CF-2024-26 and updates the compliance times to
consider airplanes in storage or airplanes operated under the low
utilization maintenance program.
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-2026-4634.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed Transport Canada AD CF-2025-61, which specifies
procedures for repetitive cleaning and greasing of all slat tracks,
including the slat track rollers, the slat pinion gear bearings, and
the slat pinion gears to prevent damage (e.g., Reametal wear) and
corrosion; repetitive general visual inspections (GVIs) of the slat
tracks for any damage or corrosion, and correct application of grease;
and applicable on-condition actions. On-condition actions include
reworking and treating the area with either phosphate pre-treatment or
silane pre-treatment if damage consists of abrasion, scratches,
corrosion, or nicks, and performing a magnetic particle inspection
(MPI) or high-frequency eddy current (HFEC) on the repair area of the
slat track. Transport Canada AD CF-2025-61 also specifies procedures
for an alternative method of compliance for the inspections.
The FAA also reviewed Spirit AeroSystems Service Bulletin 500SHW-
57-4201, Issue No. 003, dated June 17, 2025, which specifies procedures
for cleaning, inspecting, and greasing of slat tracks and applicable
on-condition repairs.
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
These products have been approved by the civil 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, that authority 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-2025-61 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-2025-61 by reference
in the FAA final rule. This proposed AD would, therefore, require
compliance with Transport Canada AD CF-2025-61 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-2025-61 for compliance will be available at
<a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2026-4634 after the FAA final rule
is published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 161 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 2022-25- Up to 15 work-hours $0 Up to $1,275....... Up to $77,775.
05. x $85 per hour =
$1,275.
[[Page 25811]]
New proposed actions............. Up to 242 work- 0 Up to $20,570...... Up to $3,311,770.
hours x $85 per
hour = $20,570.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions *
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
8 work-hours x $85 per hour = $680 $0 $680 per slat track.
per slat track.
------------------------------------------------------------------------
* This table does not include on-condition repair costs.
The FAA has received no definitive data on which to base the cost
estimates for the on-condition repairs specified in this proposed AD.
According to the manufacturer, some or all of the costs of this
proposed AD may be covered under warranty, thereby reducing the cost
impact on affected operators. The FAA does not control warranty
coverage for affected operators. As a result, the FAA has included all
known costs in the cost estimate.
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

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:
0
a. Removing Airworthiness Directive (AD) 2022-25-05, Amendment 39-22261
(87 FR 77487, December 19, 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-2026-4634; Project Identifier MCAI-2024-00508-T.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by June 26, 2026.
(b) Affected ADs
This AD replaces AD 2022-25-05, Amendment 39-22261 (87 FR 77487,
December 19, 2022) (AD 2022-25-05).
(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 BD-500-1A11
airplanes, certificated in any category, as identified in Transport
Canada AD CF-2025-61, dated November 24, 2025 (Transport Canada AD
CF-2025-61).
(d) Subject
Air Transport Association (ATA) of America Code 57, Wings.
(e) Unsafe Condition
This AD was prompted by a report that corrosion and wear were
discovered on the slat tracks due to insufficient grease applied to
the slat tracks during production, and the discovery that previous
slat track repairs required the use of inappropriate non-destructive
test (NDT) methods and, therefore, may have allowed cracks to remain
undetected on slat tracks that were previously repaired. The FAA is
issuing this AD to address corrosion and wear on the slat tracks,
which could lead to loss of one or more slat panels or loss of slat
track guidance. The unsafe condition, if not addressed, could result
in catastrophic structural damage to the wings or other parts of the
airplane due to slat panels departing from the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraphs (h) and (i) of this AD: Comply
with all required actions and compliance times specified in, and in
accordance with, Transport Canada AD CF-2025-61.
[[Page 25812]]
(h) Exception to Transport Canada AD CF-2025-61
(1) Where Transport Canada AD CF-2025-61 refers to its effective
date, this AD requires using the effective date of this AD.

actions in accordance with ``the VSB,'' this AD requires using
Spirit AeroSystems Service Bulletin 500SHW-57-4201, Issue No. 003,
dated June 17, 2025.
(3) Where Transport Canada CF-2025-61 refers to hours air time,
this AD requires using flight hours.
(4) Where Transport Canada AD CF-2025-61 defines Group B as
airplanes with ``more than 2550 total hour air time'', this AD
requires replacing that text with ``equal to or more than 2,550
total flight hours''.
(5) Where Transport Canada AD CF-2025-61 specifies to accomplish
certain actions using both the ``applicable SB'' and ``the VSB'' as
defined in Transport Canada AD CF-2025-61, this AD requires using
only ``the VSB''.
(6) Where Transport Canada AD CF-2025-61 specifies accomplishing
certain actions using ``the VSB'', for this AD replace the text
``Part A of the VSB'' with ``section 2., Procedure, of Part A of the
VSB'' and replace the text ``Part B of the VSB'' with ``section 2.,
Procedure, of Part B of the VSB''.
(i) No Reporting Requirement
Although the material referenced in Transport Canada AD CF-2025-
61 specifies to submit certain information to the manufacturer, this
AD does not include that requirement.
