Background

    The CAAI, which is the aviation authority for Israel, has issued 
CAAI AD ISR I-05-2025-09-1, dated September 1, 2025 (CAAI AD ISR I-05-
2025-09-1) (also referred to as the MCAI), to correct an unsafe 
condition for all Gulfstream Aerospace LP Model Gulfstream 200 and 
Galaxy airplanes. The MCAI states that new or more restrictive 
airworthiness limitations have been developed.
    The FAA is proposing this AD to address fatigue damage in principal 
structural elements. The unsafe condition, if not addressed, could 
result in reduced structural integrity of the airplane. You may examine 
the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-2026-
4652.

Material Incorporated by Reference Under 1 CFR Part 51

    The FAA reviewed CAAI AD ISR I-05-2025-09-1, which specifies new or 
more restrictive airworthiness limitations for airplane structures and 
safe life limits.
    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

    These products have been approved by the civil aviation authority 
of another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with this State of Design 
Authority, that authority has notified the FAA of the unsafe condition 
described in the MCAI. The FAA is issuing this NPRM after determining 
that the unsafe condition described previously is likely to exist or 
develop in other products of the same type design.

Proposed AD Requirements in This NPRM

    This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new airworthiness 
limitations, which are specified in CAAI AD ISR I-05-2025-09-1 
described previously, as incorporated by reference. Any differences 
with CAAI AD ISR I-05-2025-09-1 are identified as exceptions in the 
regulatory text of this proposed AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with Sec.  91.403(c), the operator must request 
approval for an alternative method of compliance (AMOC) according to 
paragraph (j)(1) of this proposed AD.

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, the 
FAA proposes to incorporate CAAI AD ISR I-05-2025-09-1 by reference in 
the FAA final rule. This proposed AD would, therefore, require 
compliance with CAAI AD ISR I-05-2025-09-1 through that incorporation, 
except for any differences identified as exceptions in the regulatory 
text of this proposed AD. Material required by CAAI AD ISR I-05-2025-
09-1 for compliance will be available at <a href="http://regulations.gov">regulations.gov</a> by searching

[[Page 34180]]

for and locating Docket No. FAA-2026-4652 after the FAA final rule is 
published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections) or intervals may be used unless the actions and intervals 
are approved as an AMOC in accordance with the procedures specified in 
the AMOC paragraph under ``Additional AD Provisions.'' This new format 
includes a ``Provisions for Alternative Actions and Intervals'' 
paragraph that does not specifically refer to AMOCs, but operators may 
still request an AMOC to use an alternative action or interval.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 163 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate. Therefore, the agency estimates the average total cost per 
operator to be $7,650 (90 work-hours x $85 per work-hour).

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

    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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
