Airworthiness Directives; Saab AB, Support and Services (Formerly 
Known as Saab AB, Saab Aeronautics) Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Saab AB, Support and Services Model SAAB 2000 airplanes. This AD was 
prompted by a determination that new or more restrictive airworthiness 
limitations are necessary. This AD requires revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations, as specified in a European 
Union Aviation Safety Agency (EASA) 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 May 26, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 26, 
2020.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0263, dated October 22, 2019 
(``EASA AD 2019-0263'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Saab AB, Support and Services Model SAAB 2000 
airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Saab AB, Support 
and Services Model SAAB 2000 airplanes. The NPRM published in the 
Federal Register on January 17, 2020 (85 FR 2911). The NPRM was 
prompted by a determination that new or more restrictive airworthiness 
limitations are necessary. The NPRM proposed to require revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations, as 
specified in an EASA AD.
    The FAA is issuing this AD 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. See the MCAI for additional background 
information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. We received no comments on the NPRM or on 
the determination of the cost to the public.

Clarification of Paragraph (i) of This AD

    Once a maintenance or inspection program is revised as required by 
paragraph (g) of this AD, paragraph (i) of this AD does not allow for 
the later

[[Page 21765]]

use of alternative actions or intervals unless these alternative 
actions or intervals are approved as specified in the ``Ref. 
Publications'' section of EASA AD 2019-0288. In the NPRM, the FAA 
proposed language using the word ``except.'' To make the language 
consistent with the language in the ``Ref. Publications'' section of 
EASA AD 2019-0288, the FAA has changed the wording to ``unless they are 
approved.''

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0263 describes airworthiness limitations for safe life 
limits, structural limitation items, and fuel airworthiness items, as 
well as certification maintenance requirements. 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 11 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    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. 
In the past, the agency has estimated that this action takes 1 work 
hour per airplane. 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. Therefore, the agency estimates the average total 
cost per operator 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.

maintenance or inspection program, as applicable, to incorporate the 
``limitations, tasks and associated thresholds and intervals'' 
specified in paragraph (3) of EASA AD 2019-0263 within 90 days after 
the effective date of this AD.
    (3) The initial compliance time for doing the tasks specified in 
paragraph (3) of EASA AD 2019-0263 is at the applicable ``associated 
thresholds'' specified in paragraph (3) of EASA AD 2019-0263, or 
within 90 days after the effective date of this AD, whichever occurs 
later.
    (4) The provisions specified in paragraphs (4) and (5) of EASA 
AD 2019-0263 do not apply to this AD.
    (5) The ``Remarks'' section of EASA AD 2019-0263 does not apply 
to this AD.

(i) New Provisions for Alternative Actions, Intervals, and Critical 
Design Configuration Control Limitations (CDCCLs)

    After the maintenance or inspection program has been revised as 
required by paragraph (g) of this AD, no alternative actions (e.g.,
