Beechcraft Baron 58P, 58PA, 58TC & 58TCA Aircraft 1975–2002 Maintenance Manual (P/N 102-590000-5A25)

This Raytheon Aircraft maintenance manual covers the 1975–2002 Beechcraft Baron 58P and 58PA Pressurized and 58TC and 58TCA Turbocharged models. Publication P/N 102-590000-5A25, revised June 28, 2002, organizes maintenance information by aircraft system, with serial-specific instructions for TJ and TK airframes.

• Inspections and airframe: Scheduled and unscheduled inspection guides, structural repair practices, wing attachment inspections, corrosion checks, and storage procedures.

• Cabin systems: Pressurization troubleshooting, cabin leakage testing, door-seal component replacement, heater diagnosis, and air-conditioning service.

• Flight controls: Aileron, rudder, elevator, and trim-system rigging, control-cable replacement, flap-drive service, and control-surface balancing.

• Landing gear and brakes: Gear removal and installation, retraction-system rigging, warning-system checks, wheel inspection, and hydraulic brake bleeding.

• Powerplant and fuel: Engine removal and installation, fuel-cell service, selector-valve rigging, turbocharger troubleshooting, and propeller-governor adjustment.

• Electrical diagnosis: Alternator, voltage-regulator, battery, ignition, and starter troubleshooting, with electrical test arrangements and component-location drawings.

• Ice protection: Airfoil and propeller deice troubleshooting, boot replacement, timer checks, brush and slip-ring inspection, and windshield-heater testing.

This manual is suited to qualified aircraft maintenance personnel equipped for control-system rigging, electrical testing, and pressurization checks; the inspection guide specifically relies on certified airframe and powerplant expertise.

Airframe Inspections and Structural Service

The GAMA/ATA chapter organization separates routine servicing from individual aircraft systems. The 100-hour inspection guide and 1,200-hour nose landing gear corrosion inspection accompany storage and return-to-service procedures, plus inspections following hard landings, turbulent-air encounters, and lightning strikes.

Wing-bolt and attachment-fitting inspections address corrosion and mechanical damage. Other sections cover fuselage and nacelle access, empennage inspections, stabilizer removal, door adjustment, and window replacement. The Aircraft Dimensions illustration and Stations Diagram provide reference points for locating the areas described.

Flight Controls, Landing Gear and Brakes

Control-system instructions distinguish single “throw-over” and dual control-column arrangements. Cable-tension diagrams, trim-tab free-play checks, and balancing procedures support work beyond routine lubrication.

Landing-gear coverage extends to the motor and actuator, uplock and downlock adjustments, shimmy damper, limit switches, and warning horn. Brake sections include master-cylinder linkage adjustment and parking-brake service.

The manual warns that electrical gear operation with the emergency handcrank engaged can damage the worm-shaft engagement slot. It also identifies torque-knee damage from sudden strut extension or overinflation while the aircraft is on jacks.

Pressurization, Heating and Pneumatic Systems

Pressurization troubleshooting connects cabin-pressure symptoms with the controller, outflow valve, safety/dump valve, and associated plumbing. The Cabin Pressure Control System Schematic accompanies functional checks and leakage-test equipment requirements.

Door-seal instructions distinguish serial-dependent pumps, controls, and pressure-tank installations. Heater and cooling sections add component removal, installation, and functional testing; oxygen-system coverage includes cylinder replacement and purging. Pneumatic-system procedures address pressure pumps, filters, and regulator adjustment.

Engine Installation, Fuel and Propeller Service

Powerplant chapters include engine troubleshooting, removal and installation, idle-mixture adjustment, oil-pressure adjustment, and cowl-flap rigging. The turbocharger section explains wastegate control and covers installation, initial run-in, and pressure-controller linkage adjustment.

Engine overhaul scope: Detailed internal engine overhaul is assigned to the separate Continental Engine Overhaul and Maintenance Manual, P/N X30042, which is not included.

The Fuel System Schematic supports coverage of fuel cells, boost pumps, crossfeed, and selector controls. Propeller sections distinguish Hartzell and McCauley installations and cover governor adjustment, synchronization, synchrophaser testing, and optional dual-speed governors.

Electrical Testing and Deice Fault Isolation

The Electrical Load Distribution Schematic accompanies alternator load-sharing checks, voltage-regulator adjustment, and overvoltage-sensor testing. Ignition coverage includes Bendix S-1200 magneto timing and harness routing.

The Airfoil Deice System Schematic and propeller-deice test circuits complement troubleshooting tables. For electrothermal propeller deicing, the test-unit drawing and diagnostic flowchart distinguish wiring, timer, brush, and boot faults, helping technicians narrow the cause before replacing components.

Avionics scope: Communications coverage addresses static dischargers. Detailed autopilot maintenance is referred to Edo-Aire Mitchell Bulletin No. 572, and the separate aircraft Wiring Diagram Manuals are not included.

Safety notice: Always consult a certified aviation technician and adhere to current FAA regulations before performing service. Flight-control, landing-gear, and pressurization work requires current applicable maintenance data.

Examples of Electrical Inspection and Ground-Power Requirements

Electrical operational inspections specify an external supply maintained at 28.25 ± 0.25 volts.

For ground checks and assisted engine starts, the external-power section specifies a ground power unit capable of supplying a continuous 300-amp load at 24–30 volts.
