    Notice of proposed rulemaking (NPRM).

    SUMMARY:

    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 from the supplier of a manufacturing quality escape in which some sensing elements were manufactured with insufficient salt fill. This could result in an inability to detect hot bleed air leaks. This proposed AD would require, depending on airplane serial number, reviewing the airplane maintenance records for affected bleed leak detection system sensing elements, testing the sensing elements, replacing those that fail, and witness marking those that pass, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is proposed for incorporation by reference. This proposed AD would also prohibit the installation of affected parts under certain conditions. The FAA is

    TCCA, which is the aviation authority for Canada, has issued TCCA AD CF-2022-13, dated March 28, 2022 (TCCA AD CF-2022-13) (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 Airbus Canada Limited Partnership received disclosure letters from the supplier that reported a manufacturing quality escape in which some of the overheat detection sensing elements were manufactured with insufficient salt fill. These sensing elements are used by the bleed air leak detection system for temperature detection in the event of a hot bleed air leak. Insufficient salt fill can result in an inability to detect hot bleed air leaks, which can cause damage to surrounding structures and systems that could prevent continued safe flight and landing.

    You may examine the MCAI in the AD docket at
    regulations.gov
    under Docket No. FAA-2022-1483.

    Related Service Information Under1 CFR Part 51

    TCCA AD CF-2022-13 specifies procedures for, depending on airplane serial number, reviewing the airplane maintenance records for affected bleed leak detection system sensing elements, testing the sensing elements, replacing those that fail, and witness marking those that pass. TCCA AD CF-2022-13 also prohibits the installation of any affected parts unless it is a serviceable part.

    Kidde Aerospace & Defense Service Bulletin CFD-26-1, Revision 6, dated February 28, 2022, specifies affected continuous fire detector (CFD) part numbers and testing procedures.

    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 TCCA AD CF-2022-13 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD.
    Start Printed Page 72418

    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-2022-13 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with TCCA AD CF-2022-13 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-2022-13 for compliance will be available at regulations.gov under Docket No. FAA-2022-1483 after the FAA final rule is published.

    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:

    Estimated Costs for Required Actions

    Labor cost Parts cost Cost per
    product
    Cost on U.S.
    operators
    Up to 125 work-hours × $85 per hour = $10,625 (for Group A, 52 airplanes) 0 Up to $10,625 Up to $552,500.
    Up to 1 work-hours × $85 per hour = $85 (for Group B, 17 airplanes) 0 Up to $85 Up to $1,445.

    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
    Up to 58 work-hours × $85 per hour = $4,930 (for Group A airplanes) Up to $101,045 Up to $105,975.
    Up to 183 work-hours × $85 per hour = $15,555 (for Group B airplanes) Up to $101,045 Up to $116,600.

    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.

    List of Subjects in 14 CFR Part 39

    The Proposed Amendment

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