FAR 21.23 and FAR 21.29 effective February 1, 1965. Airworthiness Requirements for sailplanes and powered sailplanes (LFSM). dated October 1975. Type Certificate No. G37EU, issued January 6, 1978. Date of Application for Type Certificate: April 15, 1977. The German Airworthiness Authori ty, the Luftfahrt-Bundesamt (LBA), originally type certificated this glider under its Type Certificate Number 317. The FAA validated this product under U.S. Type Certificate Number G37EU. Effective September 28, 2003, the European Union Aviation Safety Agency (EASA) began oversight of this product on behalf of Germany. The EASA TCDS number is EASA.A.095. Validation Basis. Type Certificate No. G37EU was issued in accordance to FAR 21.29(a)(1) in validation of LBA certification of compliance to the Federal Republic of Germany Sailplanes and Powered Sailplanes Airworthiness Requirements (LFSM) dated October 1975. Import Requirements. The FAA can issue a U.S. airworthiness certificate based on a German Export Certificate of Airworthiness (Export C of A) signed by a representative of the LBA. 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. G37EU and to be in a condition for safe operation.” All model LS 3 and LS 3-a gliders are eligible for a U.S. Standard Airworthiness Certificate, if all import requirements of this TCDS are satisfied. 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 ce rtificate for imported aircraft. Model LS 3 serial nos 3002 through 3319 are eligible for a U.S. Standard Airworthiness Certificate when all actions or modifications have been accomplished in accordance with LBA-approved Rolladen Schneider Technical Bulletin 3011. Model LS 3-a serial numbers 3259, 3274, 3280,3281, 3287, 3305, 3314, 3315, 3324 to 3328, 3332, 2249 to 3355, 3357, 3359, 3373 to 3378, 3398, 3399, 3401, 3422, 3423 are eligible for a U.S. Standard Airworthiness Certificate when all actions or modifications have been accomplished in accordance with LBA approved Rolladen-Schneider Technical Bulletin. Equipment. The basic required equipment as prescribed in the applicable airworthiness regulations (see Certification Basis) must be installed in the glider for certification. As listed in Service/Maintenance Manual the following equipment must be installed. 1. Non-cloud flying - Airspeed indicator - Altimeter - Magnetic compass 2. Cloud flying - Turn and slip - Variometer 3. LS 3/LS 3-a Flight and Service / Maintenance Manual approved by the LBA. Service Information. Each of the documents listed below must state that it is approved by the EASA or – for approvals made before September 28, 2003 – by the LBA. G37EU 4 • 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. 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. NOTES. NOTE 1. Current weight and balance report including list of equipment in certificated empty weight, and loading instructions, when necessary, must be provided for each glider at the time of original certification. NOTE 2. A. The following placard must be installed in full view of the pilot: 1. Airspeed Limits (I.A.S.)
