14 CFR Part 39

[Docket No. FAA-2022-1253; Project Identifier MCAI-2022-00698-T; 
Amendment 39-22349; AD 2023-04-02]

Airworthiness Directives; Gulfstream Aerospace LP Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Gulfstream Aerospace LP Model Gulfstream G280 airplanes. This AD was 
prompted by a determination that the existing wet runway performance 
tables in the airplane flight manual (AFM) may not provide an 
acceptable level of safety. This AD requires revising the existing AFM 
to incorporate new wet runway performance tables, as specified in a 
Civil Aviation Authority of Israel (CAAI) AD, which is incorporated by 
reference. The FAA is issuing this AD to address the unsafe condition 
on these products.

DATES: This AD is effective April 7, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 7, 
2023.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2022-1253; or in person at Docket Operations between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD 
docket contains this final rule, the mandatory continuing airworthiness 
information (MCAI), any comments received, and other information. The 
address for Docket Operations is U.S. Department of Transportation,

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 all Gulfstream 
Aerospace LP Model Gulfstream G280 airplanes. The NPRM published in the 
Federal Register on October 5, 2022 (87 FR 60344). The NPRM was 
prompted by AD ISR-I-97-2022-04-9, dated May 1, 2022, issued by the 
Civil Aviation Authority of Israel (CAAI), which is the aviation 
authority for Israel (CAAI AD ISR-I-97-2022-04-9) (also referred to as 
the MCAI). The MCAI states that the existing wet runway performance 
tables in the AFM may not provide an acceptable level of safety, and 
that the wet runway performance tables have been updated in the 
Performance section of the G280 AFM, Revision 10.
    In the NPRM, the FAA proposed to require revising the existing AFM 
to incorporate new wet runway performance tables, as specified in CAAI 
AD ISR-I-97-2022-04-9. The FAA is issuing this AD to address the 
existing AFM wet runway performance tables that could allow the 
airplane to experience runway excursions or overruns during takeoff.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1253.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from one individual. The following 
presents the comments received on the NPRM and the FAA's response to 
each comment.

[[Page 13302]]

Request To Produce Digital Version of AFM

    The commenter noted that the FAA should change AFMs to a digital 
format so they can be updated as new ADs are created.
    The FAA issues ADs to address unsafe conditions, including those 
involving the AFM. The question of whether AFMs should be produced in 
another format is beyond the scope of this AD.

Request for Clarification on Adequacy of Performance Tables

    The commenter also remarked that an effort should be made to 
understand why wet runway performance tables do not have an acceptable 
level of safety. The commenter argued that a deficiency such as this 
should have been caught during the aircraft certification process.
    Airplane certification and validation activities provide a baseline 
for safety. However, it is not possible to anticipate all potential 
unsafe conditions on an airplane during the certification process. Once 
the airplane is in service, the FAA issues ADs in accordance with 14 
CFR 39.5 when the agency subsequently finds that an unsafe condition 
exists in the airplane and the condition is likely to exist or develop 
in other airplanes of the same type design. The FAA has not changed 
this AD as a result of this comment.

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, considered the 
comments received, 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 NPRM. None of the 
changes will increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    CAAI AD ISR-I-97-2022-04-9 specifies procedures for updating the 
Performance section of the G280 AFM to incorporate new wet runway 
tables. 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 would affect 195 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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.
