Beechcraft Baron 55, A55, B55 (1965–1972) Illustrated Parts Catalog - Volume 1 & 2 (P/N 96-590010-13B3)

• Covers 1965–1972 Beechcraft Baron 55, A55, B55, C55, D55, and E55 series aircraft for component identification and serial-specific parts reference
• Identified as Raytheon Aircraft OEM publication P/N 96-590010-13B3, with a stated reissue date of March 10, 1978 and revision date of August 1, 2001
• 1,673-page illustrated parts catalog arranged in two volumes, with Volume 1 covering chapters 11 through 35 and Volume 2 continuing the catalog through chapter 80
• Uses an indenture-based parts structure to relate major assemblies, subassemblies, and individual detail parts to their associated part numbers
• Provides alphabetical and alpha-numeric indexing together with airplane serial applicability for configuration-sensitive parts identification

Parts Documentation Overview

Accurate parts identification matters on older Baron airframes, where visually similar components may apply only to a particular production configuration or airplane serial range. This illustrated parts catalog is organized around the aircraft's major airframe, power plant, and systems assemblies and provides the component relationships needed before parts are ordered or existing installations are disassembled for repair.

The catalog is divided into two volumes and follows an ATA-style chapter structure. Volume 1 covers chapters 11–35, while the second volume carries the remaining illustrated parts documentation through chapter 80. Rather than presenting components as isolated part numbers, the listings use an indenture system that shows how assemblies break down into subassemblies and individual detail parts. That structure is particularly useful when a mechanic needs to determine whether a required item is serviced separately or belongs to a larger assembly.

Illustrated breakdowns are paired with numbered parts listings so the mechanic can move from an installed assembly to the corresponding reference number and part-number entry. Coverage extends across major aircraft systems including flight-control installations, environmental-system components, electrical power equipment, landing gear, and power-plant-related assemblies.

Serial Applicability and Part-Number Cross-Reference

Serial applicability is a key part of the catalog. The listings identify parts against applicable airplane production ranges, allowing technicians and restoration shops to distinguish configuration changes that may otherwise be difficult to recognize from the installed hardware alone. This is especially important on aircraft that have accumulated decades of repairs, replacements, and configuration changes.

Alphabetical and alpha-numeric indexes provide another route into the catalog when a component description or part number is already known. Mechanics can cross-reference the index back to the applicable chapter, illustration, and detailed listing rather than searching an entire volume manually.

For restoration work, that arrangement also helps establish the parts originally associated with a particular aircraft configuration. A component that appears physically interchangeable may carry different catalog applicability, so the airplane serial number should be checked against the listing before a replacement part is selected.

What This Catalog Is — and Is Not

This publication is an illustrated parts catalog, not a workshop repair manual. Its purpose is component identification, assembly breakdown, part-number cross-reference, and airplane applicability. It can support repair planning by showing what parts make up an installation and which entries correspond to a particular serial range, but it does not provide diagnostic troubleshooting or step-by-step repair instructions.

The PDF is therefore suited to technicians, aircraft restoration shops, maintainers, and experienced owners who need factory-format parts reference material for the Baron 55 family. It should be used alongside the applicable maintenance data when performing actual repair, adjustment, inspection, or installation work.

Because aircraft parts applicability can depend on serial number and configuration, verify the individual catalog entry against the specific airframe before installation and use current FAA-required maintenance information, airworthiness directives, and approved technical data for the work being performed.
