 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2024-1473; Project Identifier MCAI-2024-00195-T; Amendment 39-22817; AD 2024-16-11]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), DOT.
 ACTION: Final rule.
 SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by reports of excessive thickness of the trailing edge of certain ailerons, which may affect the assembly of the rear spar with the lower and upper skins. This AD requires a one-time ultrasonic or visual inspection of the aileron rear spar and trailing edge areas, and applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
 DATES: This AD is effective October 23, 2024. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of October 23, 2024.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply on all Dassault Aviation Model FALCON 7X airplanes. The NPRM published in the 
                    **Federal Register**
                     on May 23, 2024 (89 FR 45612). The NPRM was prompted by AD 2024-0076, dated March 19, 2024, issued by EASA, which is the Technical Agent for the Member States of the European Union (EASA AD 2024-0076) (also referred to as the MCAI). The MCAI states that excessive 
                    ( print page 76402)
                    thickness was found on the trailing edge of certain ailerons, which may affect the assembly of the rear spar with the lower and upper skins. The unsafe condition, if not addressed, could result in reduced structural integrity of the aileron. In the NPRM, the FAA proposed to require a one-time ultrasonic or visual inspection of the aileron rear spar and trailing edge areas, and applicable corrective actions, as specified in EASA AD 2024-0076. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at 
                    *regulations.gov*
                     under Docket No. FAA-2024-1473. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion 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 referenced above. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Material Incorporated by Reference Under 1 CFR Part 51 EASA AD 2024-0076 specifies procedures for one-time ultrasonic and visual inspections for discrepancies (excessive paint thickness) of the aileron rear spar and trailing edge areas, and repair of discrepant parts. 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. Costs of Compliance The FAA estimates that this AD affects 160 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. 
                             operators21 work-hours × $85 per hour = $1,785
$324
$2,109
$337,440
 The FAA estimates the following costs to do any necessary on-condition action 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 this on-condition action: Estimated Costs of On-Condition Actions
Labor cost
Parts cost
Cost per product11 work-hours × $85 per hour = $935
$296
$1,231
 The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this 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 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, (2) Will not affect intrastate aviation in Alaska, and (3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

 The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES
 1.The authority citation for part 39 continues to read as follows: Authority:
                        49 U.S.C. 106(g), 40113, 44701. § 39.13
 2.The FAA amends § 39.13 by adding the following new airworthiness directive: 
 
 **2024-16-11 Dassault Aviation:**
                             Amendment 39-22817; Docket No. FAA-2024-1473; Project Identifier MCAI-2024-00195-T. (a) Effective Date This airworthiness directive (AD) is effective October 23, 2024. (b) Affected ADs None. (c) Applicability This AD applies to all Dassault Aviation Model FALCON 7X airplanes, certificated in any category. **Note 1 to paragraph (c):**
                             Model FALCON 7X airplanes with modification M1000 incorporated are commonly referred to as “Model FALCON 8X” airplanes as a marketing designation. (d) Subject Air Transport Association (ATA) of America Code: 57, Wings. (e) Unsafe Condition This AD was prompted by reports of excessive thickness of the trailing edge of certain ailerons, which may affect the assembly of the rear spar with the lower and upper skins. The FAA is issuing this AD to address the thickness of the trailing edge of certain ailerons. The unsafe condition, if not addressed, could result in reduced structural integrity of the aileron. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2024-0076, dated March 19, 2024 (EASA AD 2024-0076). (h) Exceptions to EASA AD 2024-0076 (1) Where paragraph (3) of EASA AD 2024-0076 specifies to “contact Dassault for approved corrective action(s) instructions and accomplish those instructions accordingly,” this AD requires replacing that text with “repair the discrepancy using a method approved by the Manager, International Validation Branch, FAA; or EASA; or Dassault's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.” (2) This AD does not adopt the “Remarks” section of EASA AD 2024-0076. (i) No Reporting Requirement Although the service information referenced in EASA AD 2024-0076 specifies to submit certain information to the manufacturer, this AD does not include that requirement. (j) Additional AD Provisions The following provisions also apply to this AD: (1)
