The General Inspectorate of Civil Aviation of Poland originally type certificated this engine.
The FAA validated this product under U.S. Type Certificate Number E9EA. Effective
September 28, 2003, the European Aviation Safety Agency (EASA) began oversight of this
product on behalf of Poland.
PRODUCTION BASIS 1. Production Certificate No. 9 for U.S. production. There will be no further production
of engines or replacement parts under this production certificate.
2. FAR 21.500 for production of engines or replacement parts under this type certificate
by WSK "PZL-RZESZOW" SA under control of the Republic of Poland General
Inspectorate of Civil Aviation (GICA).
Parts produced under either production basis are eligible to be used interchangeably.
IMPORT REQUIREMENTS To be considered eligible for installation on U.S. registered aircraft, each new engine to be
exported to the United States with the General Inspectorate of Civil Aviation of Poland or
EASA airworthiness approval shall have a Joint Aviation Authorities (JAA) or EASA Form
1, Authorized Release Certificate. The JAA or EASA Form 1 should state that the engine
conforms to the type design approved under the U.S. Type Certificate E9EA, is in a
condition for safe operation and has undergone a final operational check.
Additional guidance is contained in FAA Advisory Circular 21-23, Airworthiness
Certification of Civil Aircraft, Engines, Propellers, and Related Products, imported into the
United States.
