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 https://www.regulations.gov 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 
https://regulations.gov, 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
----------------------------------------------------------------------------------------------------------------

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

    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.

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.
