NOTE 12. PWA Turbojet Engine Service Bulletin No. 238 lists approved brand oil. NOTE 13. JTI2A-6 engines which have been modified in accordance with PWA Engineering Change No. 110181 (Aves Kit) should have the suffix letter “A” added to the engine serial number. All JT12A-6A are so 1E9 4 modified. NOTE 14. MODEL GENERAL CHARACTERISTICS JT12A-6 Basic model JT12A-6A Same as JT 12A-6 except for increased maximum continuous rating with improved engine parts. JT12A-8 Same as JT12A-6A except for increased ratings with improved engine parts. J60-P-5B See Note 15 below. NOTE 15. The J60-P-5B turbojet engine is identical to the JT12A-6A engine and is eligible for use in certificated aircraft. When the J60-P-5B is overhauled, it must undergo a parts conformity to ensure that it meets the JT12A-6A engine parts list. At that time, the JP60-P-5B engine data plate should be revised to reflect the JT12A-6A model designation. - END -
