Background
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA AD 2019-0308, dated December 18, 2019 (referred to after
this as ``the MCAI''), to address the unsafe condition on Aircraft
Industries a.s. Models L-410 UVP-Turbolet, L-410 UVP-E, L 410 UVP-E9, L
410 UVP-LW, L 410 UVP-E-LW, L 410 UVP-E20, L 410 UVP-E20 CARGO and L-
420 airplanes. The MCAI states:
Malfunction of the steering on the nose landing gear was
reported by L-410 operators. Investigation determined that the
malfunction was due to loss of the vertical pin further to a
cracking of the retaining bolt on the nose landing gear control.
[[Page 36484]]
This condition, if not detected and corrected, could lead to
reduced control of the aeroplane during taxiing, take-off and
landing.
To address this potential unsafe condition, Aircraft Industries
developed an improved pin and issued the applicable SB [service
bulletin] to provide inspection and modification instructions.
For the reason described above, this [EASA] AD requires a one-
time inspection of the the [sic] nose landing gear leg to determine
if an affected part is installed, and replacement of affected parts
with improved pins.
You may examine the MCAI in the AD docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0510.
Related Service Information Under 1 CFR Part 51
The FAA reviewed LET Aircraft Industries Mandatory Bulletin SB No.
L-420/021a, Revision 1, dated October 29, 2019, as applicable to Model
L-420 airplanes; and LET Aircraft Industries Mandatory Bulletin SB No.
L410UVP-E/144a, Revision 1, dated October 29, 2019, as applicable to
Models L 410 UVP-E20 and L 410 UVP-E20 CARGO airplanes. For the
airplane models specified on each document, the service information
contains procedures for inspecting the NLG steering lever assembly
vertical pin and replacing it if part number (P/N) L3 223 016 with a
retaining bolt is installed. This service information 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.
FAA's Determination
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, it has
notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA is issuing this AD
because it evaluated all information provided by the State of Design
Authority and determined the unsafe condition described previously is
likely to exist or develop on other products of the same type design.
AD Requirements
This AD requires accomplishing the actions specified in the service
information already described. This AD also prohibits installing a
vertical pin P/N L3 223 016 in the NLG steering lever assembly on any
airplane.
Differences Between This AD and the MCAI
The MCAI applies to Models L-410 UVP-Turbolet, L-410 UVP-E, L 410
UVP-E9, L 410 UVP-LW, and L 410 UVP-E-LW. This AD does not because
those models do not have an FAA type certificate.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because there
are no airplanes currently on the U.S. registry and thus, it is
unlikely that the FAA will receive any adverse comments or useful
information about this AD from U.S. operators. Accordingly, notice and
opportunity for prior public comment are unnecessary pursuant to 5
U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists
pursuant to 5 U.S.C. 553(d) for making this amendment effective in less
than 30 days for the same reasons the FAA found good cause to forego
notice and comment.
Costs of Compliance
There are currently no affected airplanes on the U.S. registry. In
the event an affected product becomes a U.S.-registered product, the
following is an estimate of the costs to comply with this AD.
The FAA estimates that it would take .5 work-hour per airplane to
comply with the inspection required by this AD. The average labor rate
is $85 per work-hour. Based on these figures, the FAA estimates the
cost of this AD to be $42.50 per airplane.
In addition, the FAA estimates that replacing the vertical pin, if
necessary, would take 1 work-hour and require parts costing $2,000 for
a cost of $2,085 per airplane.
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 Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.
Regulatory Findings
The FAA determined that 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, and
(2) Will not affect intrastate aviation in Alaska.
