This Cessna Model 500 Series Component Maintenance Manual gives aviation maintenance technicians and repair stations the complete procedures needed to service, examine, troubleshoot, remove, replace, disassemble, repair, and reassemble the major repairable components installed on Cessna Citation 500, 550, S550, 550 Bravo, and 560 series business jets. Every component chapter is organized to ATA Specification 2200 iSpec 2200 standards, with a standardized page-block numbering system that separates Description and Operation, Testing and Troubleshooting, Disassembly, Cleaning, Check, Repair, Assembly, Fits and Clearances, Special Tools, and Illustrated Parts List into clearly defined sections. This structure lets a technician jump directly to the exact procedure needed without searching through unrelated content.

The manual covers the thrust reverser junction box logic control circuits that manage solenoid valve operation and hydraulic power to the thrust reversers, including complete wiring diagrams, isolation diode checks, and functional test procedures using the 6587000-1 junction box tester. Trim tab actuator coverage spans aileron, rudder, and elevator actuators with detailed screw travel tests, end play limits, screw alignment specifications, disassembly and assembly sequences, and bearing installation procedures including groove pin repair.

The electric trim actuator chapter documents the 28 VDC bidirectional motor, clutch assembly, cable drum, and slip clutch adjustment with torque conversion charts and spring scale test setups. Flap/elevator trim mixer assembly coverage includes free running torque checks, slip clutch breakaway torque testing, gearset and switch plate disassembly, and detailed fits and clearances for the pinion shaft, ring gear, planet gears, and bearings.

Flap gearbox overhaul procedures cover the 5565175-18, -28, -31, -38, and -41 configurations with complete disassembly, bearing removal and installation, gear and shaft replacement, and Heli-Coil thread repair for the attach flange mounting holes. Speed brake actuator coverage includes hydraulic functional testing at 1500 PSI and 2250 PSI proof pressure, phosphate ester fluid safety precautions, packing and seal replacement, and locknut torque procedures.

Main gear assembly coverage details the trunnion, shock strut, axle, and torque link construction with servicing procedures for both the 5541000 and 6541000 series, including nitrogen charge pressures, oil leak troubleshooting, chrome plating inspection using copper sulfate solution, and piston inner diameter honing procedures. Main landing gear coverage spans the 6541410, 6541420, 6641000, 6641000-33, and 6541510/6541520 series with trunnion, trailing link, axle, and oleo assembly procedures, corrosion inspection and repair limits for the piston axle adaptor and axle, outer bearing breather vent modification, and complete oleo servicing and leak test procedures.

Nose landing gear coverage includes the 5542000 and 6642000 series with shock strut filling, piston bearing wear testing using a dial indicator and spring scale, torque link removal and installation, fork crack repair procedures, and trunnion elongated hole repair at the shimmy damper push-pull rod attach boss. Shimmy damper coverage spans the 5543001 series and DDA55146-1 with hydraulic function testing, 1500 PSIG pressure testing, extraction tool usage for orifice and check valve removal, makeup piston adjustment, and temperature-dependent service dimensions.

Uplock and sequence actuator coverage includes functional testing at 1500 PSIG, ball valve inspection, packing and backup ring replacement, and safety wire procedures. Throughout the manual, every component chapter provides complete Fits and Clearances sections listing bearing diameters, shaft dimensions, bore tolerances, surface finish requirements, and concentricity limits with both English and metric units.

Special tools, fixtures, and test equipment are documented with part numbers, manufacturer Federal Supply Codes, and fabrication instructions where applicable. The Illustrated Parts List sections for each component provide item numbers, part numbers, nomenclature, effectivity codes, and units per assembly, with exploded view illustrations showing the relationship of each part to the assembly.

This Cessna Model 500 Series Component Maintenance Manual is the definitive reference for any A&P mechanic, avionics technician, or repair station performing component-level maintenance on Citation 500 series aircraft thrust reverser, flight control, and landing gear systems.

Why This Component Maintenance Manual Matters

Component-level maintenance on Cessna Citation business jets requires exact procedures and precise specifications. Installing a thrust reverser junction box with an open isolation diode, reassembling a trim tab actuator with incorrect end play, or servicing a main gear strut to the wrong nitrogen pressure can lead to system failure, damage to adjacent components, or unsafe flight conditions.

IMAGES PREVIEW

This manual provides the manufacturer’s procedures for every repairable component in the thrust reverser, trim, flap, speed brake, and landing gear systems, with the exact torque values, clearances, test pressures, and inspection criteria needed to restore each unit to airworthy condition. The functional test procedures alone – including the complete step-by-step junction box tester sequence, the electric trim actuator clutch slippage test, and the nose gear piston bearing wear test – give a technician the ability to verify proper operation before and after repair, catching problems that a visual inspection would miss.

The Illustrated Parts Lists allow accurate parts ordering with correct effectivity by aircraft serial number, preventing the installation of incompatible components. The Fits and Clearances data provides the dimensional limits needed to determine whether a part can be reused, repaired, or must be replaced. For any shop performing component maintenance on Cessna 500 series aircraft, this manual is the primary source for continued airworthiness instructions.
