Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes. This proposed AD was prompted by a report of inadequate clearance between the fuel probes and forward fuel tank structure. This proposed AD would require measuring the clearance between certain fuel probes and the forward fuel tank structure, and reinstalling the probes if necessary, as specified in a Civil Aviation Authority of Israel (CAAI) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA must receive comments on this proposed AD by June 11, 2020.
You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods:

The CAAI, which is the aviation authority for Israel, has issued Israeli AD ISR-I-53-19-10-5, dated October 10, 2019 (“Israeli AD ISR-I-53-19-10-5”) (also referred to as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes.
This proposed AD was prompted by a report of inadequate clearance between certain fuel probes (probe No.1 and probe No.3) and the forward fuel tank structure. The FAA is proposing this AD to address such inadequate clearance, which could result in a potential source of ignition in a fuel tank, possible fire, and consequent reduced structural integrity of the airplane. See the MCAI for additional background information.
Related IBR Material Under 1 CFR Part 51
Israeli AD ISR-I-53-19-10-5 requires checking the clearance between forward fuel probes No. 1 and aft probe No. 3 and the forward fuel tank structure, by measuring each probe's distance to the adjacent skin, and adjusting the clearance, including reinstallation of the probes at the correct distance if necessary. 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 and Requirements of This Proposed AD
This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to a bilateral agreement with the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would require accomplishing the actions specified in Israeli AD ISR-I-53-19-10-5 described previously, as incorporated by reference.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and the European Union Aviation Safety Agency (EASA) to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities to use this process. As a result, Israeli AD ISR-I-53-19-10-5 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with Israeli AD ISR-I-53-19-10-5 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information specified in Israeli AD ISR-I-53-19-10-5 that is required for compliance with Israeli AD ISR-I-53-19-10-5 will be available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2020-0334 after the FAA final rule is published.
Costs of Compliance
The FAA estimates that this proposed AD affects 80 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD:
Start Printed Page 23261
Estimated Costs for Required Actions
|Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Up to 20 work-hours × $85 per hour = $1,700||$0||Up to $1,700||Up to $136,000.|
According to the manufacturer, some or all of the costs of this proposed 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.
The FAA has determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation:
(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.
