Airworthiness Directive · Amendment 39-16088 · Flight controls
Scheibe-Flugzeugbau GmbH Models Bergfalke-III, Bergfalke-II/55, SF 25C, and SF-26A Standard Gliders
This AD applies to Models Bergfalke-III, Bergfalke-II/55, SF 25C, and SF-26A Standard gliders, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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:
Unless already done, do the following actions:
(1) At the next scheduled maintenance inspection after January 4, 2010 (the effective date of this AD) or within the next 12 months after January 4, 2010 (the effective date of this AD), whichever occurs first, inspect the drive arm of the mechanical elevator trim tab for separation of the drive arm following Scheibe Aircraft GmbH Service Bulletin No. 104-24/1; No. 232-6/1; and No. 653-91/1 (same document), dated June 25, 2009. If any looseness is found, before further flight, repair the drive arm of the mechanical elevator trim tab following Scheibe Aircraft GmbH Work Instruction No. 104-24; No. 232-6; and No. 653-91 (same document), dated March 23, 2009.
(2) Repetitively thereafter, at intervals not to exceed every 12 months, inspect the drive arm of the mechanical elevator trim tab and do all corrective actions following Scheibe Aircraft GmbH Service Bulletin No. 104-24/1; No. 232-6/1; and No. 653-91/1 (same document), dated June 25, 2009; and Scheibe Aircraft GmbH Work Instruction No. 104-24; No. 232-6; and No. 653-91 (same document), dated March 23, 2009.
Note 1: The service information references four documents: 104-24 (104-24/1), 232-6 (232-6/1), 653-91 (653-91/1), and 770-30 (770-30/1). This AD does not reference 770-30 (770-30/1) because the Model SF28A Tandem Falke is not type certificated in the United States. 14 CFR part 39 only allows the FAA to issue ADs against type certificated products.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
