SUPPLEMENTARY INFORMATION: Discussion of Final Airworthiness Directive Background Comments 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 regulations.gov 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 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: lotter on DSK11XQN23PROD with RULES1 ESTIMATED COSTS FOR REQUIRED ACTIONS Cost per product Labor cost Parts cost 29 work-hours × $85 per hour = $2,465 ...................................................

The FAA has no way of determining the 22361 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 × $85 per hour = $850 .......................................................................................................... $0 Up to $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. List of Subjects in 14 CFR Part 39 Authority for This Rulemaking Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: 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. lotter on DSK11XQN23PROD with RULES1 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.

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 regulations.gov 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.

----------------------------------------------------------------------------------------------------------------


[[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.
