determination about the confidential
status of the information and treat it
according to its determination.
Factors of interest to DOE when
evaluating requests to treat submitted
information as confidential include (1) a
description of the items, (2) whether
and why such items are customarily
treated as confidential within the
industry, (3) whether the information is
generally known by or available from
other sources, (4) whether the
information has previously been made
available to others without obligation
concerning its confidentiality, (5) an
explanation of the competitive injury to
the submitting person which would
result from public disclosure, (6) when
such information might lose its
confidential character due to the
passage of time, and (7) why disclosure
of the information would be contrary to
the public interest.
It is DOE’s policy that all comments
may be included in the public docket,
without change and as received,
including any personal information
provided in the comments (except
information deemed to be exempt from
public disclosure).
DOE considers public participation to
be a very important part of the process
for developing test procedures and
energy conservation standards. DOE
actively encourages the participation
and interaction of the public during the
comment period in each stage of the
process. Interactions with and between
members of the public provide a
balanced discussion of the issues and
assist DOE in the process. Anyone who
wishes to be added to the DOE mailing

AGENCY
: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION
: Notice of proposed rulemaking
(NPRM).
SUMMARY
: We propose to supersede
Airworthiness Directive (AD) 2018–21–
04 for Glasflugel Models Club Libelle
205, H 301 ‘‘Libelle,’’ H 301B ‘‘Libelle,’’
Kestrel, Mosquito, Standard ‘‘Libelle,’’
and Standard Libelle-201B gliders. This
proposed AD results from mandatory
continuing airworthiness information
(MCAI) originated by an aviation
authority of another country to identify
and correct an unsafe condition on an
aviation product. The MCAI describes
the unsafe condition as jamming
between the double two-ring end of the
towing cable and the deflector angles of
the center of gravity (C.G.) release
mechanism. We are issuing this
proposed AD to require actions to
address the unsafe condition on these
products.

Discussion
We issued a Final rule; request for
comment to add AD 2018–21–04,
Amendment 39–19462 (83 FR 53573,
October 24, 2018) (‘‘AD 2018–21–04’’) to
address an unsafe condition on
Glasflugel Models Club Libelle 205, H
301 ‘‘Libelle,’’ H 301B ‘‘Libelle,’’
Kestrel, Mosquito, Standard ‘‘Libelle,’’
and Standard Libelle-201B gliders. AD
2018–21–04 requires inspecting the
distance between the deflector-angles of
the C.G. release mechanism and revising
the operations section of the sailplane
flight manual (SFM) before the next
winch launch.
AD 2018–21–04 was based on MCAI
originated by an aviation authority of
another country. The European Aviation
Safety Agency (EASA), which is the
Technical Agent for the Member States
of the European Community, has issued
Emergency AD No. 2018–0143–E
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for the
specified products. The MCAI states:
Jamming between the double two ring end
of the towing cable and the deflector angles
of the C.G. release mechanism was reported.
Subsequent investigation identified incorrect
geometry of the deflector angles of the
affected part as likely cause of the jamming.
This condition, if not detected and
corrected, could lead to failure to disconnect
the towing cable, possibly resulting in
reduced or loss of control of the sailplane.
To address this potential unsafe condition,
Glasfaser Flugzeug-Service GmbH issued the
TN [Technical Note] to provide inspection
instructions and corrective action.
For the reasons described above, this
[EASA] AD requires repetitive inspections of
the affected part, and, depending on findings,
accomplishment of applicable corrective
action(s). This [EASA] AD also requires
amendment of the sailplane Aircraft Flight
Manual (AFM).
We issued AD 2018–21–04 as an
interim action to address the immediate
need for the initial inspection of the
distance between the deflector-angles of
the C.G. release mechanism, any
necessary corrective action, and the
revision of the flying operations section
of the SFM. We are proposing this
superseding AD to address the long-
term need to repeat the inspection of the
C.G. release mechanism for the distance
between the deflector-angles at intervals
not to exceed 12 months. Because this
proposed requirement is for a longer
interval, we are providing the public an
opportunity to comment. You may
examine the MCAI on the internet at
http://www.regulations.gov by searching
for and locating Docket No. FAA–2019–
0560.
Related Service Information Under 1
CFR Part 51
We reviewed Glasfaser-Flugzeug-
Service GmbH Technical Note No. 5–
2018, dated June 25, 2018, which is
incorporated by reference in AD 2018–
21–04. The service information
describes procedures for measuring the
distance between the deflector-angles at
the C.G. release and modifying the
deflector-angles if necessary. 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 of
this NPRM.
FAA’s Determination and Requirements
of the Proposed AD
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, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Costs of Compliance
We estimate that this proposed AD
will affect 177 products of U.S. registry.
We also estimate that it would take
about 1 work-hour per product to
comply with the inspection
requirements and revision of the flying
operations section of the sailplane flight
manual of this proposed AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate
the cost of the AD on U.S. operators to
be $15,045, or $85 per product, per
inspection cycle.
We estimate that any modification of
the deflector-angles that may be
necessary as a result of the inspection
would take about 4 work-hours and
require parts costing $100, for a cost of
$440 per product. We have no way of
determining the number of products
that may need these actions.
This proposed AD retains the actions
of AD 2018–21–04. The estimated costs
of initial inspection, any necessary
modification, and revision of the flying
operations section of the SFM remain
the same as AD 2018–21–04 and do not
impose an additional burden beyond the
cost of repeating the inspection every 12
months.
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.
We are 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

Federal Register / Vol. 84, No. 150 / Monday, August 5, 2019 / Proposed Rules
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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to small airplanes, gliders,
balloons, airships, domestic business jet
transport airplanes, and associated
appliances to the Director of the Policy
and Innovation Division.
Regulatory Findings
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 this proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,
1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13 [Amended]
2. The FAA amends § 39.13 by
removing Airworthiness Directive (AD)
2018–21–04, Amendment 39–19462 (83
FR 53573; October 24, 2018), and
adding the following new AD:
Glasflugel: Docket No. FAA–2019–0560;
Product Identifier 2018–CE–056–AD.
(a) Comments Due Date
We must receive comments by September
19, 2019.
(b) Affected ADs
This AD replaces AD 2018–21–04,
Amendment 39–19462 (83 FR 53573, October
24, 2018) (‘‘AD 2018–21–04’’).
(c) Applicability
This AD applies to Glasflugel Models Club
Libelle 205, H 301 ‘‘Libelle,’’ H 301B
‘‘Libelle,’’ Kestrel, Mosquito, Standard
‘‘Libelle,’’ and Standard Libelle-201B gliders,
certificated in any category, with a center of
gravity (C.G.) tow release installed.
(d) Subject
Air Transport Association of America
(ATA) Code 25: Equipment/Furnishing.
(e) Reason
This proposed AD was prompted by
mandatory continuing airworthiness
information (MCAI) issued by the aviation
authority of another country to identify and
correct an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as jamming between the double
two-ring end of the towing cable and the
deflector angles of the C.G. release
mechanism. We are issuing this AD to
prevent failure of the towing cable to
disconnect, which could result in reduced or
loss of control of the glider or the cable
breaking and causing injury to people on the
ground.
(f) Actions and Compliance
Unless already done, do the following
actions in paragraphs (f)(1) through (3) of this
AD.
(1) Before the next winch launch after
November 13, 2018 (the effective date of AD
2018–21–04) and thereafter at intervals not to
exceed 12 months, inspect the distance
between the deflector-angles by following
paragraph 1 in the Actions section of
Glasfaser-Flugzeug-Service GmbH Technical
Note No. 5–2018, dated June 25, 2018.
(2) If the distance is less than 36 mm
during any inspection required in paragraph
(f)(1) of this AD, before the next winch
launch, do the corrective action in paragraph
2 in the Actions section of Glasfaser-
Flugzeug-Service GmbH Technical Note No.
5–2018, dated June 25, 2018.
(3) Before the next winch launch after
November 13, 2018 (the effective date of AD
2018–21–04), revise the flying operations
section of the sailplane flight manual by
inserting the text in paragraph (f)(3)(i) of this
AD into the winch tow section.
(i) Winch launching is permissible only
with a connecting ring pair that conforms to
aeronautical standard LN 65091.
(ii) This action may be done by the owner/
operator (pilot) holding at least a private pilot
certificate and must be entered into the
aircraft records showing compliance with
this AD by following 14 CFR 43.9 (a)(1)
through (4) and 14 CFR 91.417(a)(2)(v). The
record must be maintained as required by 14
CFR 91.417, 121.380, or 135.439.
(g) Alternative Methods of Compliance
(AMOCs)
The Manager, Standards Office, FAA, has
the authority to approve AMOCs for this AD,
if requested using the procedures found in 14
CFR 39.19. Send information to ATTN: Jim
