 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule; request for comments.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by reports that the inflation valve safety pin has been found installed on the nitrogen bottle of a certain escape slide in-service and may be installed on the nitrogen bottles of certain other escape slides on other airplanes in-service. This AD requires inspecting the inflation valve of the nitrogen bottle of the escape slide for the presence of the safety pin, and if the safety pin is installed, removing the safety pin from the inflation valve and stowing it in the safety pin stowage pouch of the escape slide, as specified in a Transport Canada Civil Aviation (TCCA) Emergency AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD becomes effective June 15, 2022. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 15, 2022. The FAA must receive comments on this AD by July 15, 2022.

Background The TCCA, which is the aviation authority for Canada, has issued TCCA Emergency AD CF-2022-23, dated April 22, 2022 (TCCA Emergency AD CF-2022-23) (also referred to as the MCAI), 
                    ( print page 32290)
                    to correct an unsafe condition for certain 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. This AD was prompted by reports that the inflation valve safety pin has been found installed on the nitrogen bottle of two forward passenger door escape slides in-service and may be installed on the nitrogen bottles of the forward and aft passenger and service door escape slides on other airplanes in-service. The inflation valve safety pin may be installed on up to four of the six nitrogen bottles of the escape slides used for the emergency exits. The FAA is issuing this AD to address installed inflation valve safety pins, which, if not removed, could prevent the deployment of the affected escape slides during an emergency evacuation, thereby significantly impeding emergency egress. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 TCCA Emergency AD CF-2022-23 specifies procedures for a detailed inspection of the inflation valve of the nitrogen bottle of the escape slide for the presence of the safety pin, and applicable on-condition actions. The on-condition actions include removing the safety pin from the inflation valve and stowing it in the safety pin stowage pouch of the escape slide. 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 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 described above. The FAA is issuing this AD after determining that the unsafe condition described previously is likely to exist or develop on other products of these same type designs. Requirements of This AD This AD requires accomplishing the actions specified in TCCA Emergency AD CF-2022-23 described previously, except for any differences identified as exceptions in the regulatory text of this 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, TCCA Emergency AD CF-2022-23 is incorporated by reference in this AD. This AD requires compliance with TCCA Emergency AD CF-2022-23 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Service information required by TCCA Emergency AD CF-2022-23 for compliance will be available at 
                    *https://www.regulations.gov*
                     by searching for and locating Docket No. FAA-2022-0594 after this AD is published. FAA's Justification and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 
                    *et seq.*) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for “good cause,” finds that those procedures are “impracticable, unnecessary, or contrary to the public interest.” Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because an inflation valve safety pin installed on the nitrogen bottle of escape slides could prevent the deployment of the affected escape slides during an emergency evacuation, and this unsafe condition may simultaneously affect up to four out of the six emergency exits. The non-deployment of a majority of the emergency escape slides could significantly affect emergency egress during an emergency evacuation. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment. Regulatory Flexibility Act (RFA) The requirements of the RFA do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 54 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs for Required Actions
Labor cost
Parts cost
Cost per
                             product
Cost on U.S.
                             operators3 work-hours × $85 per hour = $255
$0
$255
$13,770
 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:
                    ( print page 32291) Estimated Costs of On-Condition Actions
Labor cost
Parts cost
Cost per
                             product1 work-hour × $85 per hour = $85
$0
$85
 According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. 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 This AD will not have federalism implications under Executive Order 13132. This AD will 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 that this AD: (1) Is not a “significant regulatory action” under Executive Order 12866, and (2) Will not affect intrastate aviation in Alaska.
