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.

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.
