Eligible As of Serial # 35001 Import Requirements The FAA can issue a U.S. airworthiness certificate based on a German Airworthiness Authority Export Certificate of Airworthiness (Export C of A) signed by a representative of the Luftfahrt-Bundesamt (LBA) on behalf of the European Community. The Export C of A should contain the following statement: “The aircraft covered by this certificate has been examined, tested, and found to conform to the type design approved under U.S. Type Certificate No. G57EU and to be in a condition for safe operation.” 3 G57EU An airplane maintenance manual in compliance with JAR 22.1529 must be furnished before delivery of the first airplane or issuance of standard certificate of airworthiness whichever occurs later. Refer to the applicable bilateral agreement to verify eligibility for import into the United States of both new and used aircraft based on the scope of the agreement, to identify any required statements by the exporting authority on the export certificate of airworthiness (or equivalent document), and for procedures for coordinating exceptions to conformity statements on these documents. Refer to FAA Order 8130.2, Airworthiness Certification of Aircraft, for requirements for issuance of an airworthiness certificate for imported aircraft. Certification Basis 1) 14 CFR Sections 21.29, 21.183(c), and JAR-22 (Joint Airworthiness Requirements for Sailplanes and Powered Sailplanes), dated 27 June 1989 (Change 4 of the English original edition) including "Orange Papers" Amendment 22/90/1 dated 12 February 1991 and Amendment 22/92/1 for propeller 2.

The German Airworthiness Authority, the Luftfahrt-Bundesamt (LBA), originally type certificated glider Model G103 C TWIN III SL under its Type Certificate Number 869. The FAA validated this product under U.S. Type Certificate Number G57EU. Effective September 28, 2003, the European Aviation Safety Agency (EASA) began oversight of this product on behalf of Germany. The EASA TCDS number is EASA.A.250 Equipment The basic required equipment as prescribed in the applicable airworthiness regulations (see Certification Basis) must be installed in the airplane for certification. Service Information Each of the documents listed below must state that it is approved by the European Aviation Safety Agency (EASA) or – for approvals made before September 28, 2003 – by the German Airworthiness Authority (LBA). • Service bulletins • Structural repair manuals • Vendor manuals • Aircraft flight manuals • Overhaul and maintenance manuals The FAA accepts such documents and considers them FAA-approved for type design data unless one of the following conditions exist: • The documents change the limitations, performance, or procedures of the FAA approved manuals. G57EU 4 The FAA uses the post type validation procedures to approve these documents. The FAA may delegate case-by-case approval to EASA on behalf of the FAA for the U.S. type certificate. If this is the case it will be noted on the document.
