This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.
FederalRegister.gov retrieves relevant information about this document from Regulations.gov to provide users with additional context. This information is not part of the official Federal Register document.
Federal Aviation Administration (FAA), DOT.
Final rule; correction.
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 .
This final rule is effective November 18, 2015.
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.

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. ( printed 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.
1. The authority citation for part 39 continues to read as follows:
2. The FAA amends § 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.
This airworthiness directive (AD) becomes effective on November 18, 2015.
None.
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.
Air Transport Association of America (ATA) Code 27: Flight Controls.
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.
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.
