SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2021-26-05, Amendment 39-21863 (87 FR 1335,
January 11, 2022) (AD 2021-26-05). AD 2021-26-05 applied to all Saab
AB, Support and Services Model SAAB 2000 airplanes. AD 2021-26-05
required revising the existing maintenance or inspection program, as
applicable, to incorporate new or more restrictive airworthiness
limitations. The FAA issued AD 2021-26-05 to address, among other
things, fatigue cracking of principal structural elements (PSEs) and
corrosion prevention and control. This unsafe condition, if not
addressed, could result in reduced structural integrity of a PSE, and
lead to loss of control of the airplane.
The NPRM published in the Federal Register on May 14, 2024 (89 FR
41903). The NPRM was prompted by AD 2023-0220, dated December 21, 2023
(EASA AD 2023-0220) (also referred to as the MCAI), issued by EASA,
which is the Technical Agent for the Member States of the European
Union. The MCAI states new or more restrictive airworthiness
limitations have been developed.
In the NPRM, the FAA proposed to continue to require certain
actions in AD 2021-26-05 and to require revising the existing
maintenance or inspection program, as applicable, to incorporate new or
more restrictive airworthiness limitations, as specified in EASA AD
2023-0220. The FAA is issuing this AD to address among other things,
fatigue cracking of PSEs and corrosion prevention and control. The
unsafe condition, if not addressed, could result in reduced structural
integrity of a PSE,
[[Page 76407]]
and lead to loss of control of the airplane.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-1293.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM 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 NPRM. None of the changes will increase the economic burden on any
operator.
Related Material Under 1 CFR Part 51
EASA AD 2023-0220 specifies new or more restrictive airworthiness
limitations for airplane structures and safe life limits.
This AD also requires EASA AD 2021-0132, dated May 25, 2021, which
the Director of the Federal Register approved for incorporation by
reference as of February 15, 2022 (87 FR 1335, January 11, 2022).
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 9 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
The FAA estimates the total cost per operator for the retained
actions from AD 2021-26-05 to be $7,650 (90 work-hours x $85 per work-
hour).
The FAA has determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although the
agency recognizes that this number may vary from operator to operator.
Since operators incorporate maintenance or inspection program changes
for their affected fleet(s), the FAA has determined that a per-operator
estimate is more accurate than a per-airplane estimate.
The FAA estimates the total cost per operator for the new actions
to be $7,650 (90 work-hours x $85 per work-hour).
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.
