IMPORT REQUIREMENTS: To be considered eligible for installation on U.S. registered aircraft, each propeller to be 
exported to the United States shall be accompanied by a Certificate of Airworthiness for 
export endorsed by the LBA on behalf of the European Community which contains the 
following language: 
 
(1) This propeller conforms to its United States type design (Type Certificate Number 
P9BO) and is in a condition for safe operation. 
 
(2) This propeller has been subjected by the manufacturer to a final operational check and 
is in a proper state of airworthiness.  Reference FAR Section 21.500 which provides for 
the airworthiness acceptance of aircraft engines or propellers manufactured outside the 
U.S. for which a U.S. type certificate has been issued.  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.
