Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Gulfstream Aerospace LP Model Gulfstream G280 airplanes. The NPRM published in the Federal Register on October 5, 2022 (87 FR 60344). The NPRM was prompted by AD ISR-I-97-2022-04-9, dated May 1, 2022, issued by the Civil Aviation Authority of Israel (CAAI), which is the aviation authority for Israel (CAAI AD ISR-I-97-2022-04-9) (also referred to as the MCAI). The MCAI states that the existing wet runway performance tables in the AFM may not provide an acceptable level of safety, and that the wet runway performance tables have been updated in the Performance section of the G280 AFM, Revision 10. In the NPRM, the FAA proposed to require revising the existing AFM to incorporate new wet runway performance tables, as specified in CAAI AD ISR-I-97-2022-04-9. The FAA is issuing this AD to address the existing AFM wet runway performance tables that could allow the airplane to experience runway excursions or overruns during takeoff. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2022-1253. Discussion of Final Airworthiness Directive Comments The FAA received comments from one individual. The following presents the comments received on the NPRM and the FAA's response to each comment. Request To Produce Digital Version of AFM The commenter noted that the FAA should change AFMs to a digital format so they can be updated as new ADs are created. The FAA issues ADs to address unsafe conditions, including those involving the AFM. The question of whether AFMs should be produced in another format is beyond the scope of this AD. Request for Clarification on Adequacy of Performance Tables The commenter also remarked that an effort should be made to understand why wet runway performance tables do not have an acceptable level of safety. The commenter argued that a deficiency such as this should have been caught during the aircraft certification process. Airplane certification and validation activities provide a baseline for safety. However, it is not possible to anticipate all potential unsafe conditions on an airplane during the certification process. Once the airplane is in service, the FAA issues ADs in accordance with 14 CFR 39.5 when the agency subsequently finds that an unsafe condition exists in the airplane and the condition is likely to exist or develop in other airplanes of the same type design. The FAA has not changed this AD as a result of this comment. 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, considered the comments received, 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. Related Service Information Under 1 CFR Part 51 CAAI AD ISR-I-97-2022-04-9 specifies procedures for updating the Performance section of the G280 AFM to incorporate new wet runway tables. 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 would affect 195 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. operators 1 work-hour × $85 per hour = $85 $0 $85 $16,575 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.
