SUPPLEMENTARY INFORMATION:
Background
The CAAI, which is the aviation authority for Israel, has issued
CAAI AD I-57-2020-06-01, dated January 27, 2021 (CAAI AD I-57-2020-06-
01) (also referred to as the MCAI), to correct an unsafe condition for
certain Gulfstream Aerospace LP Model Gulfstream G280 airplanes.
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 G280 airplanes. The NPRM published in the
Federal Register on June 10, 2021 (86 FR 30819). The NPRM was prompted
by a report that during full-scale fatigue testing, a crack was found
in the area of the attachment of the wing rib 0 to the front spar. The
NPRM proposed to require non-destructive testing on the forward (front)
spar vertical stiffener and rib 0 for any cracking, installation of a
doubler to the forward (front) spar and rib 0 attachment, and repair if
necessary, as specified in CAAI AD I-57-2020-06-01.
The FAA is issuing this AD to address any cracking at the area of
the wing rib 0 to the front spar, which could affect the structural
integrity of the wing. See the MCAI for additional background
information.
Discussion of Final Airworthiness Directive Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
[[Page 50452]]
Conclusion
The FAA reviewed the relevant data and determined that air safety
requires adopting this AD as proposed. 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. Accordingly,
the FAA is issuing this AD to address the unsafe condition on these
products.
Related Service Information Under 1 CFR Part 51
CAAI AD I-57-2020-06-01 specifies procedures for non-destructive
testing (high frequency, mid frequency, and bolt hole eddy current
inspections; and a liquid (dye) penetrant inspection) for cracking on
the forward (front) spar vertical stiffener and rib 0, installation of
a doubler to the forward (front) spar and rib 0 attachment, and repair
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.
Costs of Compliance
The FAA estimates that this AD affects 23 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
----------------------------------------------------------------------------------------------------------------
80 work-hours x $85 per hour = $6,800*....................... $400 $7,200 * $165,600 *
----------------------------------------------------------------------------------------------------------------
* If the actions are accomplished during 4C Check.
The FAA has received no definitive data on which to base the cost
estimates for the repair specified in this AD.
According to the manufacturer, some or all of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators. The FAA does not control warranty coverage for
affected operators. 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.
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.
