Background
The FAA issued an NPRM to amend 14 CFR part 39 by adding an AD that
would apply to certain Gulfstream Aerospace LP Model Gulfstream 200
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, issued by CAAI, which is the aviation authority
for Israel (referred to after this as the MCAI). 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.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-0994.
Actions Since the NPRM Was Issued
Since the FAA issued the NPRM, the FAA determined that Model Galaxy
airplanes must be added to the applicability. The FAA is proposing 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.
Comments
The FAA received comments from an anonymous commenter. The
following presents the comments received on the NPRM and the FAA's
response to each comment.
Request To Add Model Galaxy Airplanes to the Applicability
The commenter requested that the FAA add Model Galaxy airplanes to
the applicability. The commenter stated that Model Galaxy airplane
serial numbers are included in the applicability of the NPRM, but the
model designation (Galaxy) is not mentioned. The commenter concluded
that owners/operators for Model Galaxy airplanes might not be aware of
the proposed AD and might not address the unsafe condition.
The FAA agrees with the request. The FAA has revised this AD to add
Model Galaxy airplanes to the applicability.
Request To Change the Model Designation From Gulfstream G200 to
Gulfstream 200
The commenter requested that the FAA change Model Gulfstream G200
airplanes to Model Gulfstream 200 airplanes in the applicability. The
commenter noted that in the FAA type certificate data sheet (TCDS)
A53NM, the model designation is Gulfstream 200. The commented stated
that the correction brings the intended model designation in line with
the FAA TCDS.
The FAA agrees with the request. The FAA has revised this AD to
change the model designation from Gulfstream G200 to Gulfstream 200.
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 ADDRESSES.
FAA's Determination
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 the State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
described above. The FAA is issuing this SNPRM after determining that
the unsafe condition described previously is likely to exist or develop
in other products of the same type design.
Certain changes described above expand the scope of the NPRM. As a
result, it is necessary to reopen the comment period to provide
additional opportunity for the public to comment on this SNPRM.
Proposed AD Requirements in This SNPRM
This proposed AD would require accomplishing the actions specified
in CAAI AD ISR I-57-2021-12-4, dated January 1, 2022, described
previously, except for any differences identified as exceptions in the
regulatory text 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-57-2021-12-4, dated January
1, 2022, by reference in the FAA final rule. This AD would, therefore,
require compliance with CAAI AD ISR I-57-2021-12-4, dated January 1,
2022, in its entirety through that incorporation, except for any
differences identified as exceptions in the regulatory text of this AD.
Service information required by CAAI AD ISR I-57-2021-12-4, dated
January 1, 2022, for compliance will be available at <a href="http://regulations.gov">regulations.gov</a>
under Docket No. FAA-2022-0994 after the FAA final rule is published.
[[Page 76150]]
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 168 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed 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
----------------------------------------------------------------------------------------------------------------
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 *
------------------------------------------------------------------------
Labor cost Parts cost Cost per product
------------------------------------------------------------------------
Up to 10 work-hours x $85 per $0 Up to $850.
hour = $850.
------------------------------------------------------------------------
* The FAA has received no definitive data on which to base the cost
estimates for the on-condition repairs specified in this proposed 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 proposed 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
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.
