14 CFR Part 39

[Docket No. FAA-2015-3224; Directorate Identifier 2015-CE-026-AD; 
Amendment 39-18290; AD 2015-20-11]

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 http://www.regulations.gov 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, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590.

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

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/
