SUPPLEMENTARY INFORMATION:
Discussion
The EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2020-0223, dated October 14, 2020
(EASA AD 2020-0223) (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 February 24, 2021 (86 FR 11184). The NPRM was
prompted by a report indicating that the left-hand MLG collapsed after
touchdown, causing severe damage to the airplane. The
[[Page 33100]]
NPRM proposed to require modifying the MLG hydraulic transfer valve, as
specified in EASA AD 2020-0223.
The FAA is issuing this AD to address abnormal behavior of the MLG
hydraulic transfer valve due to a restriction in hydraulic flow, which
could cause the MLG hydraulic transfer valve to not function properly
and fail to retract, extend, or lock the MLG, and possibly result in
MLG collapse following landing and consequent damage to the airplane
and injury to occupants. See the MCAI for additional background
information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the NPRM or
on the determination of the cost to the public.
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 Service Information Under 1 CFR Part 51
EASA AD 2020-0223 describes procedures for modifying the MLG
hydraulic transfer valve. This modification includes installing a new
relay, relocation of wiring, and installation of new wiring, to ensure
that, when the emergency extension handle is used, the transfer valve
solenoid is energized to force the transfer valve to the ``gear down''
position. 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 8 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.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
20 work-hours x $85 per hour = $1,700........................ $1,875 $3,575 $28,600
----------------------------------------------------------------------------------------------------------------
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.
