Federal Register Abstract
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to certain Schempp- Hirth Flugzeugbau GmbH Models Duo Discus and Duo Discus T gliders. The Model Duo Discus gliders were incorrectly referenced as powered sailplanes in the Applicability section. This document corrects that error and refers to both models as just gliders as in previous ADs. In all other respects, the original document remains the same; however we are publishing the entire rule in the Federal Register.

Airworthiness Directives; Schempp-Hirth Flugzeugbau GmbH Gliders
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: The FAA is correcting an airworthiness directive (AD) that
published in the Federal Register. That AD applies to certain Schempp-
Hirth Flugzeugbau GmbH Models Duo Discus and Duo Discus T gliders. The
Model Duo Discus gliders were incorrectly referenced as powered
sailplanes in the Applicability section. This document corrects that
error and refers to both models as just gliders as in previous ADs. In
all other respects, the original document remains the same; however we
are publishing the entire rule in the Federal Register.
DATES: This final rule is effective November 18, 2015.
ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2015-
3224; or in person at the Docket Management Facility between 9 a.m. and
5 p.m., Monday through Friday, except Federal holidays. The AD docket
contains this AD, the regulatory evaluation, any comments received, and
other information. The address for the Docket Office (phone: 800-647-
5527) is Document Management Facility, U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,

SUPPLEMENTARY INFORMATION: Airworthiness Directive 2015-20-11,
Amendment 39-18290 (80 FR 61722, October 14, 2015), currently requires
inspecting and replacing the airbrake bell crank and the airbrake drive
funnels and inspecting the airbrake control system for proper clearance
and making necessary adjustments.
[[Page 69114]]
As published, the Model Duo Discus gliders were incorrectly
referenced as powered sailplanes in the Applicability section. This
could cause confusion because the Model Duo Discus does not have an
engine. This document corrects that error and refers to both models as
just gliders as in previous ADs.
Although no other part of the preamble or regulatory information
has been corrected, we are publishing the entire rule in the Federal
Register.
The effective date of this AD remains November 18, 2015.
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2015-20-11 Schempp-Hirth Flugzeugbau GmbH: Amendment 39-18290;
Docket No. FAA-2015-3224; Directorate Identifier 2015-CE-026-AD.
(a) Effective Date
This airworthiness directive (AD) becomes effective on November
18, 2015.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Schempp-Hirth Flugzeugbau GmbH Model Duo
Discus gliders, serial numbers 1 through 639, and Model Duo Discus T
gliders, serial numbers 1 through 110 and 112 through 247,
certificated in any category.
(d) Subject
Air Transport Association of America (ATA) Code 27: Flight
Controls.
(e) Reason
This AD was prompted by 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 excessive load
on the air brake system. We are issuing this AD to prevent
uncontrolled actuation of the air brakes (symmetric or asymmetric),
which could result in reduced control.
(f) Actions and Compliance
Unless already done, do the actions in paragraph (f)(1) through
(f)(5) of this AD.
(1) Within 40 days after November 18, 2015 (the effective date
of this AD) and repetitively thereafter at intervals not to exceed
100 hours time-in-service until the terminating replacement action
required in paragraphs (f)(2) and (f)(3) of this AD (as applicable)
is done, inspect the airbrake bell crank, the airbrake drive
funnels, and the airbrake control system.
(i) Inspect the airbrake bell crank and the airbrake drive
funnels for cracks and damage following Action 1 in Schempp-Hirth
Flugzeugbau GmbH Technical Note No. 380 -2/396-17/868-22/890-14,
Revision 1, issued July 13, 2015 (published as a single document).
(ii) Inspect the airbrake control system for proper clearance
following Paragraph 2.d. of Schempp-Hirth Flugzeugbau GmbH Working
instruction for Technical Note No. 380-2/396-17/868-22/890-14,
Ausgabe (English translation: issue) 1, Datum (English translation:
dated) May 11, 2015.
(2) If cracks or damage is found on the airbrake bell cranks or
the airbrake drive funnels during any inspection required in
paragraph (f)(1) of this AD, before further flight, replace each
cracked or damaged part with a reinforced part. Installing a
reinforced part terminates the repetitive inspections required in
paragraph (f)(1) of this AD for that part.
(i) For replacement of the airbrake bell cranks, follow Picture
2: Reinforced version of airbrake bell crank according to HS 11-
50.016, Revision a or later, in Schempp-Hirth Flugzeugbau GmbH
Working instruction for Technical Note No. 380-2/396-17/868-22/890-
14, Ausgabe (English translation: issue) 1, Datum (English
translation: dated) May 11, 2015.
(ii) For replacement of the airbrake drive funnels, follow
Picture 5: Airbrake drive funnel in fuselage ``Reinforcement of
airbrake drive funnel according to drawing S14RB703, Revision a, in
Schempp-Hirth Flugzeugbau GmbH Working instruction for Technical
Note No. 380-2/396-17/868-22/890-14, Ausgabe (English translation:
issue) 1, Datum (English translation: dated) May 11, 2015.
(3) If no cracks or damage were found on the airbrake bell
cranks or the airbrake drive funnels during any inspection required
in paragraph (f)(1) of this AD, within 12 months after November 18,
2015 (the effective date of this AD), replace each of the airbrake
bell cranks and airbrake drive funnels with a reinforced part. These
replacements terminate the repetitive inspections required in
paragraph (f)(1) of this AD.
(i) For replacement of the airbrake bell cranks, follow Picture
2: Reinforced version of airbrake bell crank according to HS 11-
50.016, Revision a or later, in Schempp-Hirth Flugzeugbau GmbH
Working instruction for Technical Note No. 380-2/396-17/868-22/890-
14, Ausgabe (English translation: issue) 1, Datum (English
translation: dated) May 11, 2015.
(ii) For replacement of the airbrake drive funnels, follow
Picture 5: Airbrake drive funnel in fuselage, ``Reinforcement of
airbrake drive funnel according to drawing S14RB703, Revision a,''
in Schempp-Hirth Flugzeugbau GmbH Working instruction for Technical
Note No. 380-2/396-17/868-22/890-14, Ausgabe (English translation:
issue) 1, Datum (English translation: dated) May 11, 2015.
(4) If the airbrake control system is found to not have proper
clearance during the inspection required in paragraph (f)(1) of this
AD, before further flight, make all necessary corrective adjustments
following Paragraph 2.d. of Schempp-Hirth Flugzeugbau GmbH Working
instruction for Technical Note No. 380-2/396-17/868-22/890-14,
Ausgabe (English translation: issue) 1, Datum (English translation:
dated) May 11, 2015.
(5) As of November 18, 2015 (the effective date of this AD),
only install an airbrake bell crank or an airbrake drive funnel that
corresponds to Picture 2: Reinforced version of airbrake bell crank
according to HS 11-50.016, Revision a or later, and Picture 5:
Airbrake drive funnel in fuselage, ``Reinforcement of airbrake drive
funnel according to drawing S14RB703, Revision a,'' in Schempp-Hirth
Flugzeugbau GmbH Working instruction for Technical Note No. 380-2/
396-17/868-22/890-14, Ausgabe (English translation: issue) 1, Datum
(English translation: dated) May 11, 2015, as applicable.
