Engine Systems and Components Covered

The Honeywell TFE731-5BR turbofan engine is a two-spool geared turbofan with a single-stage fan, four-stage low pressure axial compressor, single-stage high pressure centrifugal compressor, single-stage high pressure turbine, and three-stage low pressure turbine. This manual addresses maintenance for all major engine sections and systems. The air inlet section covers the fan inlet housing, fan by-pass stator, and related components. The compressor section covers the low pressure compressor bearing and No. 3 seal, engine mount bushings, LP first stage compressor rotor assembly, and LP tie rod installation. The combustion section covers the plenum case drain valve, combustion chamber liner, outer transition liner, and combustion chamber plenum case. The turbine section covers the LPT roller bearing, thrust and exhaust nozzle, thermocouple harness and N1 transducer mounting brackets, LP turbine module, turbine interstage transition duct, HPT rotor assembly, and HPT nozzle assembly. The accessory drives section covers the accessory and transfer gearbox installation, accessory drive gearbox assembly, and transfer gearbox assembly. The by-pass section covers the fan spinner, fan rotor assembly, fan by-pass stator, fan duct set, fan support assembly, fan seal assembly and roller bearing, fan support and fan thrust bearing, fan shaft assembly and ring gear, lubricating nozzle, pinion gear bearing housing, quill shaft assembly, and planet gear assembly.

What This Manual Enables You to Do

With this Honeywell TFE731-5BR Turbofan Engine Light Maintenance Manual on hand, you can confidently perform a wide range of maintenance tasks. The document supports routine and major periodic inspections, component removal and installation, troubleshooting of starting, idle, acceleration, take-off, climb, cruise, deceleration, and shutdown malfunctions, servicing procedures including oil changes and compressor washes, and adjustment and test procedures for the fuel control, DEEC, surge bleed valve, and other systems.

The troubleshooting section provides tables for each phase of engine operation—starting, idle, acceleration, take-off, climb/cruise, deceleration, shutdown, and post-operation—with step-by-step procedures to isolate faults. The inspection/check section provides detailed criteria for determining component serviceability, including wear limits, clearances, and acceptance/rejection thresholds. The adjustment/test section provides procedures for DEEC adjustment, overspeed system testing, N1 transducer output testing, vibration checks, fan trim balance, fuel pump functional testing, and gearbox pressure checks. The removal/installation section provides procedures for removing and installing engine components, with torque values and tightening sequences. The approved repairs section provides procedures for repairing components within specified limits, including blending, welding, and replacement of damaged parts.

Because the manual includes the manufacturer’s inspection criteria, wear limits, torque values, and approved repair procedures, you can make informed decisions about component serviceability and carry out repairs correctly. The troubleshooting procedures guide you through fault isolation step by step, helping reduce diagnostic time. For shops and technicians supporting TFE731-5BR-powered aircraft, this TFE731-5BR maintenance manual is an indispensable reference that helps ensure work is performed to the manufacturer’s standards.
