IMPORT REQUIREMENTS To be considered eligible for installation on U.S. - registered aircraft, each engine to be 
exported to the United States shall be accompanied by a certificate of airworthiness for 
export or certifying statement endorsed by the exporting cognizant civil airworthiness 
authority and containing the following language: 
 
(1) This engine conforms to its United States type design (Type  
 Certificate Number E35NE) and is in a condition for safe operation. 
(2) This engine 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 of the U.S. and 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

NOTE  4. The engine ratings are based on dry sea level static ICAO standard atmospheric conditions.  No 
external accessory loads and no air bleed.  The quoted ratings are obtained on a test stand with the 
specified fuel and oil, without intake ducting and utilizing the exhaust duct and intake defined in the 
approved Installation Manual.

NOTE  8. The take-off ratings that are nominally limited to 5 minutes duration may be used for up to 10 
minutes for one engine inoperative operations during takeoff.  Refer to the Engine Maintenance 
Manual Chapter 05-10-00 for any subsequent required maintenance actions. 
 
NOTE  9. The PW305 and PW306 series engines are approved for multiple-engine installations only. 
 
NOTE  10. The PW305 and PW306 series engines meet Transport Canada and FAA requirements for operation 
in icing conditions.  These engines also meet the requirements of Canadian Airworthiness Manual 
533.27 and do not require external armoring. 
 
NOTE  11. Life limits for critical rotating components are published in the airworthiness limitations section of 
each maintenance manual.  The airworthiness limitations manual P/N 30B2978 for the PW306B has 
been superseded by data in the airworthiness limitations section of the maintenance manual. 
 
NOTE  12. The recommended engine operating time between overhauls and hot section inspection intervals are

NOTE  14. The PW305, PW305A, PW305B and PW306A engines include provisions for automatic power 
increase to Maximum Takeoff.  For these engine models the limitations stated for Normal Takeoff 
are to ensure that the Maximum Takeoff limitations are not exceeded in the event of an automatic 
power increase to Maximum Takeoff Power.  Refer to Table 2-1 in the Installation Manual.  For the 
PW305, PW305A, PW305B, and PW306A engine models, the Maximum Takeoff rating is the 
maximum approved takeoff power.  For the PW306B, PW306C, PW306D, and PW306D1 the 
Normal Takeoff rating is the maximum approved takeoff power.
