NOTE 2: Temperature Limits:
Maximum Interstage Turbine Temperature (ITT) Limits: °F (°C)
Maximum Oil Inlet Temperature Range, °F (°C) for all engine models:
Fan gearbox oil temperature transient of 300°F (149°C) for a maximum of 2 minutes is permitted
for all operational altitudes.
External engine components, maximum temperature (limiting temperature of
specific components) are as specified in the applicable engine installation manual,
(See Note 16).
Operation at an engine fuel inlet temperature as high as 135°F (57°C) and as low as -65°F
(-54°C) is approved with fuel at or above the pour point during starting. If fuel that does
not contain an approved anti-icing additive is used, an approved engine fuel heater, or an
alternate system capable of maintaining a fuel filter inlet temperature of 35°F, must be used.
In installations that do not use an approved fuel heater and may extract motive flow for
aircraft injector systems, engine operation with inoperative electronic fuel control is limited
to a minimum inlet fuel temperature of 12°F (- 11°C) with 1000 pounds per hour
(maximum) motive flow extraction and -31°F (-35°C) without motive flow extraction.
Installations which are equipped with the hydromechanical fuel control heater are approved
for operation with fuel inlet temperature as low as -65°F (-54°C) provided fuel is at or
above pour point.

NOTE 6. Custom Bleed Airflow Limits. Refer to the applicable engine installation manual (See Note 16).
NOTE 7. These engines meet FAA requirements for turbine disk integrity and rotor blade containment.
NOTE 8: These engines meet FAA requirements for operation in icing conditions within the envelope
defined in 14 CFR part 25, Appendix C.
NOTE 9: Certain engine parts are life limited. These limits are listed in the FAA approved Honeywell
Aerospace US LLC Service Bulletins TFE731-72-3001 and TFE731-72-3501.
NOTE 10: These engine models meet the requirements of Special Condition No. 33-44-WE-13.
NOTE 11: Variation in engine configuration and installation components are identified by a suffix to the basic

configurations rating code number(s) and “Y” denotes Honeywell Aerospace equipment code letter(s)
E6WE 7 of 7
of aircraft manufacture), and an Engine Equipment List, those items code letter (s) of aircraft
manufacture), and an Engine Equipment List number. Certain features of these components are
influenced by aircraft design considerations. In the Engine Equipment List, those items coded “E” are
basic engine items and are controlled by Part 33 of the Federal Aviation Regulations. Items coded “A”
have been demonstrated as compatible with the basic engine during engine certification testing.
However, the operation, functioning, and performance of these in a specific aircraft installation must
be demonstrated during aircraft certification. Subsequent design control associated with these factors
is the responsibility of the aircraft manufacturer.
NOTE 12: Power setting, power checks and control of engine thrust output in all operations is to be based on
Honeywell Aerospace US LLC engine charts referring to low pressure rotor speed (N1). Speed sensors
are included in the engine assembly for this purpose.
NOTE 13: The TFE731-2BR, -3R, -3AR, -3BR, -3CR, -3DR, -4R, -5AR, -5BR, and -5R turbofan engines
with their electronic fuel control systems are adjusted for the limits noted herein.
NOTE 14: For additional authorized operation and installation detailed information, see FAA-approved
sections of the applicable engine installation manual (See Note 16).
NOTE 15: These engines meet the requirements of §§ 33.68, 33.71(c), 33.75, 33.77 and 33.90
effective with Amendment 33-6.
