Type Certificate No. E-308 issued January 19, 1959; models 508 and 509 added September 1, 1959; 508A and 509A added July 12, 1963. Date of Application for Type Certificate: March 29, 1956. The aviation authority for the United Kingdom, the UK Civil Aviation Authority (CAA), originally type certificated this engine. The FAA validated this product under U.S. Type Certificate Number E-308. Effective September 28, 2003, the European Aviation Safety Agency (EASA) began oversight of this product on behalf of the UK. Import Requirements To be considered eligible for installa tion on U.S. registered aircraft, each new engine to be exported to the United States with UK CAA or EA SA airworthiness approval shall have a Joint Aviation Authorities (JAA) or EASA Form 1, Author ized 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 E-308, is in a condition for safe operation and has undergone a final operational check. NOTE 1. Maximum LP speed for takeoff, Max. Continuous cond itions and for reverse thrust, is 7335 LP r.p.m. (505, 508A, 509A) and 7356 LP r.p.m. (508, 509) NOTE 2. Maximum permissible temperatures: Turbine gas temperature (Mean of 6 thermocouples in exhaust cone): Takeoff 1247°F. (675°C.) Maximum continuous 1112°F. (600°C.) Max. transient in starting 1247°F. (675°C.) Max. with reverse thrust selected 1247°F. (675°C.) Oil inlet temperature -67°F. to +221°F. (-55 to +105°C.) NOTE 3. Fuel and oil pressure limits: Minimum fuel inlet pressure measured at inlet to engi ne main pump = 0 lb. p.s.i. for 5 minutes, and 7 p.s.i.g. unrestricted. Oil pressure normal 30-45 p.s.i. gauge (minimum in flight at 9650 HP r.p.m. = 28). NOTE 4. The ratings are based upon standard conditions with no ai r bleed or power takeoff, 60°F. and 29.92" hg. barometer, pw/po = .01, and with turbine gas temperature within limits. Engine to be fitted with straight jet pipe Part No. DES.51690, Issue 3, and 25.75" diameter final nozzle R-R Part No. CU.26100 and test bed intake flare J.59408, and using fuel of calorific volume 18,550 BThU/lb.

These engines meet FAA requirement s for vibration, icing protection, for adequate turbine disc integrity, for rotor blade containment and do no require external armoring. NOTE 7. Under all conditions compressor bleed air may be used for aircraft and engine services up to the maximum delivery permitted by the engine air bleed ports, provided that the r.p.m. or turbine gas temperature operating limitations are not exceeded. NOTE 8. The maximum allowable thrust for below standard inlet air temperatures and/or ram conditions is 20,000 lb. for five minutes at takeoff conditions. 3 E-308 NOTE 9. Maximum permissible overspeed limit for the engine rotors are as follows: Low Pressure Compressor - 7560 r.p. m. for 20 seconds (505, 508A, 509A), 7576 r.p.m. for 20 seconds (508, 509) High Pressure Compressor - 10,500 r.p.m. for 20 seconds If these limits are exceeded, the engine shall be overhauled. NOTE 10. For aircraft using percentage type tachomet ers, the following conversion factors shall be used: L.P. - 9938 H.P. r.p.m. = 100% L.P. - 6924 L.P. r.p.m. = 100% NOTE 11. The following fuels are eligible for these engines: Aviation Kerosene Specifications British D Eng. R.D. 2482 or 2494 Canadian 3-GP-23C Type 1 American A.S.T.M. D.1655-59T Type A or Type A-1 I.A.T.A.
