Import Requirements The FAA can issue a U.S. Standard Airworthiness Certificate based on an Export
Certificate of Airworthiness (Export C of A) signed by a representative of the
German civil airworthiness authority, 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 comply with U.S. airworthiness regulations 14 CFR Part 23 approved under
U.S. Type Certificate No. A57EU and to be in a condition for safe operation.’
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 14 CFR 23, effective February 1, 1965,
including Amendments 23-1 through 23-32, and
2) 14 CFR Section 36, effective November 18, 1969, including Amendments 36-1
through amendment in effect at the time of U.S. Type Certification, and
Page 6 of 7 A57EU

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 Service bulletins, aircraft flight manuals, maintenance and overhaul manuals,
structural repair manuals, and vendor manuals which contain a statement that the
document is approved by the EASA, are accepted by the FAA and are considered
FAA approved. (These approvals pertain to the design data only.)
