[Docket No. FAA-2021-0790; Project Identifier MCAI-2021-01007-T; Amendment 39-21738; AD 2021-19-20]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule; request for comments.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a report of defects on the piston hole associated with the O2 saver feature that may prevent efficient deactivation of the O2 saver function. This AD requires amending the existing airplane flight manual (AFM) to incorporate a check and an operating limitation regarding the O2 saver function, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD becomes effective September 16, 2021. The Director of the Federal Register approved the incorporation by reference of a certain publications listed in this AD as of September 16, 2021. The FAA must receive comments on this AD by November 1, 2021.

Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD 2021-0202-E, dated September 9, 2021 (EASA Emergency AD 2021-0202-E) (also referred to as the MCAI), to correct an unsafe condition for all Dassault Aviation Model FALCON 7X airplanes. EASA subsequently issued EASA AD 2021-0202R1, dated September 10, 2021 (EASA AD 2021-0202R1) to address an incorrect reference to a non-existing part number within the definition of the affected part. This AD was prompted by a report of plastic molding burrs and defects found on the piston hole associated with the O2 saver feature during production of certain SAFRAN flightcrew oxygen masks. The O2 saver function allows the flightcrew to wear the oxygen mask with limited oxygen consumption to save oxygen by delivering it only when needed, either automatically in case of depressurization, or manually by switching the 100% or EMERG mode button. Defects on the piston hole may prevent efficient deactivation of the O2 saver function. The FAA is issuing this AD to address this condition, which could lead to inadequate oxygen supply to the flightcrew in case of decompression of the airplane or smoke or fire in the flight deck. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2021-0202R1 specifies procedures for amending the existing AFM to incorporate a specific check to ensure that the O2 saver function is not activated and an operating limitation to prevent use of the O2 saver function. EASA AD 2021-0202R1 also limits the installation of affected parts under certain conditions. 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 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 this 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 the same type design. Requirements of This AD This AD requires accomplishing the actions specified in EASA AD 2021-0202R1 described previously, except for any differences identified as exceptions in the regulatory text of this AD. EASA AD 2021-0202R1 requires operators to “inform all flight crews” of amendments to the AFM, and thereafter to “operate the aeroplane accordingly.” However, this AD does not specifically require those actions as they are already required by FAA regulations. FAA regulations require operators furnish to pilots any changes to the AFM (*e.g.,*14 CFR 121.137), and to ensure that pilots are familiar with the AFM (*e.g.,*14 CFR 91.505). As with any other training requirement, training on the updated AFM content is tracked by the operators and recorded in each pilot's training record, which is available for the FAA to review. FAA regulations also require pilots to follow the procedures in the existing AFM including all updates. 14 CFR 91.9 requires that no person may operate a civil aircraft without complying with the operating limitations specified in the AFM. Therefore, including a requirement in this AD to operate the airplane according to the amended AFM would be redundant and unnecessary. 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, EASA AD 2021-0202R1 is incorporated by reference in this AD. This AD requires compliance with EASA AD 2021-0202R1 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in EASA AD 2021-0202R1 does not mean that operators need comply only with that section. For example, where the AD requirement refers to “all required actions and compliance times,” compliance with this AD requirement is not limited to the section titled “Required Action(s) and Compliance Time(s)” in EASA AD 2021-0202R1. Service information required by EASA AD 2021-0202R1 for compliance will be available at *https://www.regulations.gov* by searching for and locating Docket No. FAA-2021-0790 after this AD is published. Interim Action The FAA considers this AD interim action. If final action is later identified, the FAA might consider further rulemaking then. 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 foregoing notice and comment prior to adoption of this rule because failure to deactivate the O2( print page 51606)saver function could lead to inadequate oxygen supply to the flightcrew in case of decompression of the airplane or smoke or fire in the flight deck. 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 forego 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 20 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. operators1 work-hour × $85 per hour = $85
$0
$85
Up to $1,700.
 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.
