Background
The FAA issued AD 2025-15-04, Amendment 39-23091 (90 FR 37786,
August 6, 2025) (AD 2025-15-04), for all Gulfstream Aerospace LP Model
G150 airplanes. AD 2025-15-04 was prompted by an MCAI originated by the
CAAI, which is the aviation authority for Israel. The CAAI issued AD
ISR I-32-24-10-01R1, revised October 15, 2024 (CAAI AD ISR I-32-24-10-
01R1), to correct an unsafe condition.
AD 2025-15-04 requires revising the existing maintenance or
inspection program, as applicable, to incorporate a new airworthiness
limitation. The FAA issued AD 2025-15-04 to address failure of the nose
landing gear (NLG) actuator-to-strut attachment pin. The unsafe
condition, if not addressed, could result in failure of the NLG to
retract and lock after take-off or extend and lock before landing.
Actions Since AD 2025-15-04 Was Issued
Since the FAA issued AD 2025-15-04, the CAAI superseded AD ISR I-
32-24-10-01R1 and issued CAAI AD ISR I-05-2025-10-1, dated October 15,
2025 (CAAI AD ISR I-05-2025-10-1) (also referred to as the MCAI), for
all Gulfstream Aerospace LP Model G150 airplanes. The MCAI states that
new or more restrictive airworthiness limitations have been developed
as specified in Gulfstream 150 Maintenance Manual, Section 05-10-10,
Revision 30, dated September 15, 2025, which includes an inspection
reporting procedure.
The FAA is proposing this AD to address fatigue damage in principal
structural elements of the horizontal stabilizer and elevator systems.
The unsafe condition, if not addressed, could result in undetected
fatigue cracking in critical empennage structural components, loss of
elevator control authority, and 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-2026-4654.
Material Incorporated by Reference Under 1 CFR Part 51
CAAI AD ISR I-05-2025-10-1 specifies new or more restrictive
airworthiness limitations for airplane structures and safe life limits,
which include an inspection reporting procedure.
This proposed AD would also require CAAI AD ISR I-32-24-10-01R1,
which the Director of the Federal Register approved for incorporation
by reference as of September 10, 2025 (90 FR 37786, August 6, 2025).
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 referenced above. The FAA is issuing this NPRM
after determining that the unsafe condition described previously is
likely to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would retain all of the requirements of AD 2025-
15-04. This proposed AD would also require revising the existing
maintenance or inspection program, as applicable, to incorporate
additional new or more restrictive airworthiness limitations, including
an inspection reporting procedure, which are specified in CAAI AD ISR
I-05-2025-10-1 already described, as proposed for incorporation by
reference. Any differences with CAAI AD ISR I-05-2025-10-1 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 (m)(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 retain the Incorporation by Reference (IBR) of CAAI AD
ISR I-32-24-10-01R1 and incorporate CAAI AD ISR I-05-2025-10-1 by
reference in the FAA final rule. This proposed AD would, therefore,
require compliance with CAAI AD ISR I-32-24-10-01R1 and CAAI AD ISR I-
05-2025-10-1 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-32-24-10-01R1 is available at
<a href="http://regulations.gov">regulations.gov</a> by searching for and locating Docket No. FAA-2026-4654
and material required by CAAI AD ISR I-05-2025-10-1 for compliance will
be available at <a href="http://regulations.gov">regulations.gov</a> by searching for and locating Docket
No. FAA-2026-4654 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.
[[Page 34790]]
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 82 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD: The FAA estimates the total cost
per operator for the retained actions from AD 2025-15-04 to be $7,650
(90 work-hours x $85 per work-hour).
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.
The FAA estimates the total cost per operator for the new proposed
actions to be $7,650 (90 work-hours x $85 per work-hour).
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a currently valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to take
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information. All responses to this collection of
information are mandatory. Send comments regarding this burden estimate
or any other aspect of this collection of information, including
suggestions for reducing this burden, to: Information Collection
Clearance Officer, Federal Aviation Administration, 10101 Hillwood
Parkway, Fort Worth, TX 76177-1524.
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 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.
