NOTE 7. 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 requirements and electromagnetic interference emitted by the electronic engine control
system, including cables, are specified in the Installation and Operating Manual, Section 4.12.
NOTE 9. Fuel and fuel additives conforming 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.

NOTE 17. The PW4164, PW4168, PW4168A, PW4164C, PW4164C/B, PW4170, PW4168-1D, PW4168A-1D,
PW4164-1D, PW4164C-1D, and PW4164C/B-1D model engines have been 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
6436 which defines the various configurations and maximum operating intervals as follows:
Fault Level A: No dispatch allowed
Fault Level B: Dispatchable: maximum operating interval for Fault Level B fault(s) is
20 days.
Fault Levels A and B 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.
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. Electronic Engine Control (EEC) software version SCN5C has maximum permissible exhaust gas
temperatures of 625oC actual and 620oC indicated for takeoff (5 minutes) and 600oC for maximum
continuous. To provide an additional 20oC EGT margin, EEC software version SCN6B and later versions
can provide maximum permissible EGT of 645oC actual (620oC indicated) for takeoff, and 615oC actual
(600oC indicated) for maximum continuous. The noted engine ratings and limits are controlled by EEC P/N
and Engine Programming Plug (EPP) P/N, and are implemented by specific Service Bulletin instructions
only. The engine data plate also reflects the engine ratings and limits configuration. The indicated versus
actual EGT values are controlled by EEC software.
NOTE 19. The normal 5 minute takeoff time limit may be extended to 10 minutes for engine out contingency.
NOTE 20.
NOTE 21.
NOTE 22.
NOTE 23.
