SUPPLEMENTARY INFORMATION:

Comments Invited

The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments to an address listed under ADDRESSES . Include “Docket No. FAA–2023–1502; Project Identifier MCAI–2023–00380–T” at the beginning of your comments. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this proposal because of those comments.

Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this NPRM.

Confidential Business Information

CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this NPRM contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this NPRM, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as “PROPIN.” The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this NPRM. Submissions containing CBI should be sent to Tom Rodriguez, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone: 206–231–3226; email tom.rodriguez@faa.gov. Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking.

Background

The FAA issued an NPRM (88 FR 47086, July 21, 2023) that would apply to all Dassault Aviation Model MYSTERE–FALCON 900 airplanes. The NPRM proposed to supersede AD 2023–04–10, Amendment 39–22357 (88 FR 20743, April 7, 2023) (AD 2023–04–10), for all Dassault Aviation Model MYSTERE–FALCON 900 airplanes. AD 2023–04–10 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations.

The NPRM proposed to continue to require the actions in AD 2023–04–10 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD 2023–0046, dated March 2, 2023. The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is proposing this AD to address reduced structural integrity of the airplane.

Related Service Information Under 1 CFR Part 51

The FAA reviewed EASA AD 2023–0046. This service information specifies new or more restrictive airworthiness limitations for airplane structures and safe life limits.

This proposed AD would also require EASA AD 2022–0137, which the Director of the Federal Register approved for incorporation by reference as of May 12, 2023 (88 FR 20743, April 7, 2023).

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 .

Need for the Correction

As published, the docket number referenced throughout the NPRM is incorrect. The NPRM incorrectly references “Docket No. FAA–2023–1501.” The correct docket number is “Docket No. FAA–2023–1502.”

Although no other part of the preamble or regulatory information has been corrected, for clarity the FAA is publishing the entire proposed rule in the Federal Register .

The comment due date of the NPRM remains September 5, 2023.
