Background

Transport Canada, which is the aviation authority for Canada, has issued Transport Canada AD CF-2022-08, dated March 3, 2022 (Transport Canada AD CF-2022-08) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for 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. The MCAI states there have been several in-service findings of mechanical wear damage on the engine fuel feed system tubes and fuel tube connections on airplanes that are "post-SB BD500-282004" or that have the production equivalent. Transport Canada AD CF-2019-19R1, dated November 1, 2019 (Transport Canada AD CF-2019-19R1), among other actions, mandates modifying the fuel feed line installations in the fuel collector tanks using ACLP Service Bulletin BD500-282004, Issue 1, dated August 30, 2019. Transport Canada AD CF-2019-19R1 corresponds to FAA AD 2022-02-07, Amendment 39-21904 (87 FR 7027, February 8, 2022).

This proposed AD would require repetitive inspections of the fuel feed system for damage and replacement if necessary, as specified in Transport Canada AD CF-2022-08, which is proposed for incorporation by reference. The FAA is proposing this AD to address mechanical wear damage on the engine fuel feed system tubes and fuel tube connections. The unsafe condition, if not addressed, could result in failure of the affected fuel tubes and subsequent failure of the gravity transfer system, which could lead to a fuel imbalance resulting in a reduction in aircraft functional capabilities and increased crew workload. See the MCAI for additional background information.

You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2022-1566.

Related Service Information Under 1 CFR Part 51

Transport Canada AD CF-2022-08 specifies procedures for repetitive general visual inspections for mechanical wear damage (damage includes cracks, scores, scratches, nicks, and gouges) of the fuel feed system (the fuel feed tubes, related attaching hardware, and the area where the saddle clamp was installed), and rectification, such as replacement if any discrepancy is found after measuring any damage found during any inspection.

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 the State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI described 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-2022-08 described previously, as incorporated by reference, except for any group identified as exceptions in the regulatory text of this proposed AD.

Explanation of Required Compliance Information


[top] 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-2022-08 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with Transport Canada AD CF-2022-08 in its entirety through that incorporation, page 74529 except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information required by Transport Canada AD CF-2022-08 for compliance will be available at regulations.gov under Docket No. FAA-2022-1566 after the FAA final rule is published.

Interim Action

The FAA considers that this proposed AD would be an interim action. This AD is considered interim action and further AD action may follow.

Costs of Compliance

The FAA estimates that this AD, if adopted as proposed, would affect 69 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:

Labor cost Parts cost Cost per product Cost on U.S. operators
74 work-hours × $85 per hour = $6,290 $0 $6,290 $434,010

Labor cost Parts cost Cost per product
7 work-hours × $85 per hour = $595 $57,284 Up to $57,879.

The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected operators.

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.
