Power setting, power checks, and control of engine output in all operations are to be based upon Pratt & Whitney engine charts referring to either turbine discharge section gas pressure or low rotor speed. Pressure probes and a low rotor speed sensor are included in the engine assembly for this reason. NOTE 8. Lightning protection re quirements and electromagnetic interference emitted by the electronic engine control system, including cables, are specified in the Installation and Operating Manual, Section 5.12. NOTE 9. Fuel and fuel additives conformi ng to the latest applicable issue of FAA-approved Pratt & Whitney Turbojet Engine Service Bulletin No. 2016 may be used separately or mixed in any proportions without adversely affecting the engine operation or power output. NOTE 10. The following oils are eligible: Oils conforming to Pratt & Whitney Turbojet Engine Service Bulletin No. 238, latest revision. TCDS E46NE PAGE 6 NOTE 11. Certain engine parts are life limited. Limits are lis ted in Pratt & Whitney PW4000-112 series engine Turbofan Engine Manual, Part Number 51A345, time limit section for models PW4074, PW4077 and PW4084 and Part Number 51A751 for models PW4077D, PW4084D, PW4090, PW4090-3, and PW4074D. NOTE 12. The engines meet the smoke and gaseous emission requirements of Part 34. NOTE 13. The maximum permissible engine inlet distortion limit is specified in the Installation and Operating Manual, Section 5.4, Report PWA-6510-09. NOTE 14. Limits regarding transient ro tor shaft overspeed rpm and transient gas overtemperature and the number of overtemperature occurrences are specified in the Maintenance Document, Part No. 51A344. NOTE 15. Information regarding approved fuel filter and oil filter replacement is in the PW4000 Series Illustrated Parts Catalog, Part Number 51A346 for models PW4074, PW4077 and PW4084 and Part Number 51A742 for models PW4077D, PW4084D, PW4090, PW4090-3, and PW4074D. NOTE 16. Requirements and limitations associat ed with automatic fuel system anti-icing are specified in the Installation and Operating Manual, Section 5.5, Report PWA-6510-09. NOTE 17. The PW4000-112 series engine model engines have b een approved to operate with certain faults present in the control system, based on satisfaction of FAR 33 requirements and appropriate FAR 25 control system reliability requirements. The following criteria exist as dispatch and maintenance requirements for the engine control system. These criteria are specified in Pratt & Whitney Report PWA-6600-05 which defines the various configurations and maximum operating intervals as follows: Fault Level A: No dispatch allowed Fault Level B: Dispatchable: maximum operati ng interval for Fault Level B fault(s) is 20 days. Fault Level D: Unlimited dispatch Fault Levels A, B and D: unlimited dispatch constitute Pratt & Whitney nomenclature. The airframe manufacturers may use different nomenclature in adapting these fault categories to the aircraft maintenance and display systems. However, the maximum operating intervals are restricted as shown above. Fault Level C is not applicable for PW4000-112 series engines. A control system reliability monitoring program has been established with Pratt & Whitney in compliance with the reporting requirements as outlined in the Engine and Propeller Directorate Policy, letter dated October 18, 1993, for Time Limited Dispatch of Engine fitted with FADEC Systems. NOTE 18. The normal 5 minute takeoff time limit may be extende d to 10 minutes for one engine inoperative contingency. NOTE 19. The PW4090-3 engine model provides the same ta keoff thrust as the PW4090 engine model up to a 1000 foot altitude for all temperature days. Above 1000 feet in altitude the PW4090-3 rating provides increased takeoff thrust as a function of both ambient temperature and altitude as shown in the Installation and Operating Manual, Section 4 and Table 1, Report PW-6510-09. Above ambient temperatures of 86oF the altitude ratings do not exceed that of the sea level rating for the PW4090 and PW4090-3 engine models. ----END---- ``` ## ADs (31, in force first) - [AD 2026-17-08](https://openairdocs.org/ad/2026-17-08): Turbine Engine Compressor Section · Pratt & Whitney Division PW4074D, PW4077D, PW4084D and 2 more.
