1961–2004 Beechcraft Baron 55, A55, B55, C55, D55, E55 & 58 Aircraft Shop Manual (P/N 55-590000-13E23)

The Raytheon Aircraft Shop Manual, P/N 55-590000-13E23, revised December 31, 2004, covers maintenance and repair for 1961–2004 Beechcraft Baron 55, A55, B55, C55, D55, E55, and 58 aircraft.

• Airframe structure: Wing removal and installation, spar carry-through inspection, cabin door adjustment, window replacement, and fiberglass repair.

• Flight controls: Aileron, elevator, and rudder rigging; trim-tab checks; flap actuator service; and control-surface balancing.

• Landing gear and brakes: Landing gear actuator and nose gear shimmy damper overhaul, strut inspection, brake wear limits, and bleeding procedures.

• Powerplant and fuel: Engine removal and installation, ignition timing, fuel-pump adjustment, fuel-flow calibration, and fuel-cell replacement.

• Electrical diagnosis: Battery, charging, starter, and indicator-circuit troubleshooting, electrical load charts, and wiring diagrams with serial-number applicability.

• Environmental and utility systems: Heater and air-conditioning tests, oxygen-system checks, vacuum and pneumatic-system adjustment, and electric propeller deicer service.

The manual is written for experienced mechanics handling specialized and more complex aircraft maintenance.

Airframe Inspection and Control Rigging

Wing spar carry-through inspection distinguishes structures with and without reinforcement kits. Stations diagrams and the Wing Bolt Wrenches and Torque Adapters chart support structural work, while cabin door procedures cover removal, installation, and latching adjustment.

Control sections distinguish throw-over and dual-control arrangements and include cable-tension temperature charts, trim-tab free-play checks, and balancing after repair or repainting.

The wing-installation cautions explain how a wrench bottoming against a wing fitting can produce a false torque reading and damage the fitting.

Landing Gear Actuator and Shimmy Damper Repair

The Landing Gear Actuator Assembly exploded view accompanies internal disassembly, bearing and gear inspection, seal replacement, and reassembly instructions. Separate main-gear, nose-gear, and shimmy-damper sections provide wear-tolerance charts, inspection criteria, and repair procedures.

Engine Installation, Ignition, and Fuel Calibration

Powerplant coverage includes oil-radiator replacement, Bendix and Slick magneto timing, and Champion and A.C. spark-plug specifications. Slick magneto instructions identify the T-118 timing pin and warn that rotating the drive with the pin installed can damage the magneto.

Fuel Flow System Calibration and Correction applies to Model 58 aircraft TH-1389 and TH-1396 and After and calls for a Fisher Porter Flow Rater or equivalent. Fuel-cell procedures distinguish main, auxiliary, interconnected, and wet-wing-tip installations.

Internal engine overhaul requires the separate Continental engine publications.

Electrical Troubleshooting and Wiring Coverage

Fault charts address alternators, generators, starters, batteries, flap controls, and landing gear indicators. Electrical Utilization Charts separate standard, optional, and avionics loads by model and serial range.

Diagram examples include Fuel System, Landing Gear Position Indicator, Instrument Lights, Prop Synchronizer, and the Propeller (Hot Prop) Deice Control Schematic. The deicer diagnostic charts connect ammeter indications with circuit faults, helping distinguish an open heater circuit from a grounded power lead or timer problem.

Wiring applicability: Section 14 covers TC-1 thru TC-1935 except TC-1913; TE-1 thru TE-1063; and TH-1 thru TH-647 except TH-598. Aircraft outside these ranges require separate wiring-diagram manuals.

Alternator, generator, and starter overhaul procedures are referred to the applicable component manufacturers' publications.

Heating, Cooling, and Pneumatic Systems

Heater coverage includes combustion-tube pressure testing, component replacement, and troubleshooting. Air-conditioning procedures address functional checks, compressor service, expansion-valve adjustment, and refrigerant servicing.

Oxygen, vacuum, and pneumatic-pressure sections cover system layouts, filtering, testing, and adjustment. Electric propeller deicer coverage includes brush replacement and manufacturer-specific timer and slip-ring checks.

Pressurization: Section 9 is explicitly marked not applicable to these Baron aircraft; pressurization service procedures are not included.

Ground Handling, Finish Care, and Inspections

Jacking procedures distinguish Model 300 jacks with and without Tronair extension kits. Mooring provisions and flyable, temporary, and indefinite storage procedures cover ground handling and preservation.

Aircraft-finish coverage addresses corrosion treatment and paint repair. Lubrication charts, torque tables, consumable-materials charts, sealing charts, and flare-fitting torque charts support servicing. Inspection material includes scheduled checks and examinations after hard landings, turbulence, or lightning strikes.

Always verify specifications against your specific aircraft's current OEM documentation before flight-control or landing-gear work.

A Preview of Stabilizer Attachment Torques

These horizontal-stabilizer values are a small selection of the manual's component-specific torque data.

Front-spar mounting bolts on TC aircraft prior to TC-2457, except TC-350, are specified at 85–100 in-lb.

For TC-350, TC-2457 and After, and all TE and TH aircraft, the front-spar specification is 200–225 in-lb dry. The installation instructions distinguish these attachments from the rear-spar bolts.

Search, Bookmarks, and Diagram Legibility

Navigation and small-print detail: Searchable OCR text and chapter/topic bookmarks are included. Recognition errors can affect searches for technical codes, and some front-matter bookmarks are mislabeled. Small wiring labels require zooming; portions of diagram legends remain difficult to read even when enlarged.
