SUPPLEMENTARY INFORMATION:
Discussion
The European Union Aviation Safety Agency (EASA), which is the
Technical Agent for the Member States of the European Community, has
issued EASA AD No. 2020-0068-E, dated March 23, 2020 (referred to after
this as ``the MCAI''), to address an unsafe condition for Blanik
Aircraft CZ s.r.o. Model L 23 Super-Blanik gliders. The MCAI states:
During a standard maintenance procedure on an L 23 Super-
Blan[iacute]k sailplane, a crack was detected on a rudder control
cable attachment screw.
This condition, if not detected and corrected, could lead to
rudder control failure, possibly resulting in loss of directional
control of the sailplane.
To address this unsafe condition, BACZ [Blanik Aircraft CZ
s.r.o.] issued the MB [mandatory bulletin] and the IB [information
bulletin] to provide inspection and replacement instructions.
For the reasons described above, this [EASA] AD requires a one-
time inspection and, depending on findings, replacement of affected
parts.
Blanik Aircraft CZ s.r.o. advises that reporting by operators and
maintenance facilities indicates that this issue is not an isolated
event. You may obtain further information by examining the MCAI in the
AD docket on the internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching
for and locating Docket No. FAA-2020-0714.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Blanik Mandatory Bulletin Document No. L23/060a,
Revision 2, dated March 17, 2020, which contains procedures for
inspecting the affected parts. The FAA also reviewed Blanik Information
Bulletin Document No. L23/061b, Revision 1, dated March 17, 2020, which
contains procedures for replacing the affected parts. 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 section.
FAA's Determination
This product has been approved by EASA, and is approved for
operation in the United States. Pursuant to our bilateral agreement
with the European Union, EASA has notified us of the unsafe condition
described in the MCAI and service information referenced above. The FAA
is issuing this AD because it evaluated all the relevant information
provided by EASA and determined the unsafe condition is likely to exist
or develop in other products of the same type design.
AD Requirements
This AD requires a one-time inspection of the rudder control cable
attachment screws and hinge bolts and, if a crack is found, replacement
of the affected parts as specified in the service information described
previously. This AD also requires reporting certain information to the
manufacturer.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because the required corrective actions must be accomplished before
further flight. Therefore, the FAA finds good cause that notice and
opportunity for prior public comment are impracticable. In addition,
for the reason stated above, the FAA finds that good cause exists for
making this amendment effective in less than 30 days.
[[Page 49236]]
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this final rule. Send your comments to an address
listed under the ADDRESSES section. Include ``Docket No. FAA-2020-0714;
Product Identifier MCAI-2020-00589-G'' at the beginning of your
comments. The FAA will consider all comments received by the closing
date and may amend this AD because of those comments.
Except for Confidential Business Information as described in the
following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments we receive, without change, to
<a href="https://regulations.gov">https://regulations.gov</a>, including any personal information you
provide. The FAA will also post a report summarizing each substantive
verbal contact it receives about this AD.
Confidential Business Information
CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this AD contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this AD, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this AD. Submissions containing CBI should be sent to Jim
Rutherford, Aerospace Engineer, FAA, General Aviation & Rotorcraft
Section, International Validation Branch, 901 Locust, Room 301, Kansas
City, Missouri 64106. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
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 the FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 91 gliders of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspect rudder cable attach fasteners. 2.5 work-hours x $85.00 $0.00 $212.50 $19,337.50
per hour = $212.50.
Reporting results to the manufacturer. 1 hour x $85.00 per hour 0.00 85.00 7,735.00
= $85.00.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspection. The FAA has no way of determining the number of parts that
might need these replacements.
On-Condition Costs
----------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to a penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a currently valid OMB Control Number. The OMB
Control Number for this information collection is 2120-0056. Public
reporting for this collection of information is estimated to be
approximately 1 hour per response, including the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, completing and reviewing the collection of
information. All responses to this collection of information are
mandatory. Send comments regarding this burden estimate or any other
aspect of this collection of information, including suggestions for
reducing this burden to: Information Collection Clearance Officer,
Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX
76177-1524.
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.
[[Page 49237]]
For the reasons discussed above, I certify this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866, and
(2) Will not affect intrastate aviation in Alaska.
