Document Structure and Contents

This illustrated parts catalog provides detailed identification of replacement components for the Piper Tri-Pacer PA-22 series. Aviation technicians and mechanics will find the PDF organized into eleven primary sections. These cover the wing group, fuselage, cockpit, control surfaces, fuel system, landing gear, brake installations, electrical systems, power plant, and radio configurations. A miscellaneous group also catalogs optional kits, repair components, and specialized tools. This layout makes it highly efficient to cross-reference exact factory parts during heavy repairs, visual troubleshooting, or routine shop maintenance.

For daily workshop operations, the specific benefit of this manual is its ability to directly match sub-assemblies and AN-series hardware to granular airframe serial numbers. This precision effectively prevents costly ordering errors and reduces aircraft downtime.

Component Identification and Specification Data

Each section features exploded-view illustrations paired with precise parts lists. To fully support shop workflows, the document incorporates electrical system installation drawings, instrument panel installation views, fuel system installation drawings, and control cables installation schematics. The accompanying tables define nomenclature, part numbers, and serial number applicability, clearly distinguishing 1951 models through the final 1964 airframes. For exterior surface work, the catalog provides exhaustive standard paint charts listing original manufacturer numbers for Butyrate dopes and enamels. Hardware identification is equally straightforward. The data includes standard specifications for AN-series bolts, nuts, and cotter pins frequently encountered during airframe maintenance.

While this catalog is invaluable for sourcing the correct hardware and visualizing complex assemblies, it remains a parts identification tool rather than a written step-by-step instructional guide. However, it does include specific rigging procedure drawings and exploded views that serve as a visual sequence guide. By showing exactly how flight controls and structural systems fit together, these illustrations help DIYers properly prepare their work and verify parts orders, potentially saving an expensive trip to an aviation workshop. Technicians must rely on approved service manuals for final rigging, torque specifications, and installation procedures to ensure all hands-on maintenance meets strict aviation safety standards.
