Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed 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. This proposed AD would require repetitive cleaning and greasing of all slat tracks to prevent damage and corrosion; doing repetitive inspections of the slat tracks for any damage or corrosion, and the correct application of grease; and applicable corrective actions; as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

Background
The TCCA, which is the aviation authority for Canada, has issued
TCCA AD CF-2021-43, dated November 29, 2021 (TCCA AD CF-2021-43) (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.
This proposed AD was prompted by a report that corrosion and wear
were discovered on the slat tracks on a number of in-service airplanes
due to insufficient grease applied to the slat tracks during
production. The FAA is proposing 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 and consequently cause catastrophic
structural damage to the wings or other parts of the airplane due to
slat panels departing from the airplane. See the MCAI for additional
background information.
Related Service Information Under 1 CFR Part 51
TCCA AD CF-2021-43 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., metal wear) and corrosion; doing repetitive general visual
inspections of the slat tracks for any damage or corrosion, and the
correct application of grease; and applicable corrective actions.
Corrective actions include repairs, rework, measurements of the
reworked area, and a magnetic particle inspection of the reworked area
for any cracking. TCCA AD CF-2021-43 also specifies procedures for
reporting the inspection findings.
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.
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 the 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 these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in TCCA AD CF-2021-43 described previously, except for any differences
identified as exceptions in the regulatory text of this proposed AD.
This proposed AD would also require a reporting requirement.
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 TCCA AD CF-2021-43 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
TCCA AD CF-2021-43 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 TCCA AD CF-2021-43
for compliance will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a>
[[Page 43458]]
by searching for and locating Docket No. FAA-2022-0882 after the FAA
final rule is published.
Interim Action
The FAA considers this proposed AD interim action. If final action
is later identified, the FAA might consider further rulemaking then.
Costs of Compliance
The FAA estimates that this proposed AD would affect 61 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 15 work-hours x $85 per hour $0 Up to $1,275................. Up to $77,775.
= $1,275.
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.
The FAA estimates that it would take about 1 work-hour per product
to comply with the proposed reporting requirement in this proposed AD.
The average labor rate is $85 per hour. Based on these figures, the FAA
estimates the cost of reporting the inspection results on U.S.
operators to be $5,185, or $85 per product.
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
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
8 work-hours x $85 per hour = $680.... $0 $680
------------------------------------------------------------------------
The FAA has received no definitive data on which to base the cost
estimates for the repair specified in this proposed AD.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to take
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information. All responses to this collection of
information are mandatory. Send comments regarding this burden estimate
or any other aspect of this collection of information, including
suggestions for reducing this burden, to: Information Collection
Clearance Officer, Federal Aviation Administration, 10101 Hillwood
Parkway, Fort Worth, TX 76177-1524.
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.
