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 to certain Gulfstream
Aerospace LP Model Gulfstream G200 airplanes. The NPRM published in the
Federal Register on August 17, 2022 (87 FR 50588). The NPRM was
prompted by AD ISR I-57-2021-12-4, dated January 1, 2022 (CAAI AD ISR
I-57-2021-12-4) (also referred to as the MCAI), issued by CAAI, which
is the aviation authority for Israel. There were reports that wing flap
fairing debonding and corrosion were discovered at the lower skin of
rib 3 and rib 11 on both wings. The MCAI states that the reason for the
AD is to prevent the possibility of flap fairing debonding, moisture
intrusion and wing lower skin corrosion at rib 3 and rib 11.
In the NPRM, the FAA proposed to require an inspection for
corrosion in certain areas of the wing skin fairings, additional
inspections if necessary, resealing the fairings with new fillet seal,
and applicable corrective actions, as specified in CAAI AD ISR I-57-
2021-12-4.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-0994.
The FAA issued a supplemental notice of proposed rulemaking (SNPRM)
to amend 14 CFR part 39 by adding an AD that would apply to certain
Gulfstream Aerospace LP Model Galaxy airplanes and Model Gulfstream 200
airplanes. The SNPRM published in the Federal Register on December 13,
2022 (87 FR 76148). The SNPRM was prompted a determination that Model
Galaxy airplanes must be added to the applicability. In the SNPRM, the
FAA proposed to require an inspection for corrosion in certain areas of
the wing skin fairings, additional inspections if necessary, resealing
the fairings with new fillet seal, and applicable corrective actions.
The FAA is issuing this AD to address flap fairing debonding and
moisture intrusion that might lead to lower wing skin corrosion and
cracking on both wings, and reduced structural integrity of the wings.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the SNPRM 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 SNPRM. None of the changes will increase the economic burden on any
operator.
Related Service Information Under 1 CFR Part 51
CAAI AD ISR I-57-2021-12-4, dated January 1, 2022, describes
procedures for an inspection for corrosion in the area of the wing skin
(or doubler if installed) under the rib 3 and rib 11 fairings, a
penetration or eddy current inspection for cracks if corrosion was
found, a measurement of the thickness of remaining wing skin (or
doubler) if no cracks were found, resealing of rib 3 and rib 11
fairings with new fillet seal, and applicable corrective actions.
Corrective actions include cleaning and removing corrosion, crack
repair, and repair of fairing installation locations with a certain
thickness reduction.
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 168 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
29 work-hours x $85 per hour = $2,465......... Minimal......................... $2,465 $414,120
----------------------------------------------------------------------------------------------------------------
[[Page 22361]]
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 these on-condition actions:
Estimated Costs of On-Condition Actions [*]
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
Up to 10 work-hours x $85 per hour = $0 Up to $850
$850.................................
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost
estimates for the on-condition repairs specified in this AD.
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.
