Description

Piper PA-34-200T Seneca II Illustrated Parts Catalog

This Piper PA-34-200T Seneca II Illustrated Parts Catalog is a comprehensive, illustrated parts reference for the Seneca II twin-engine aircraft, published under Piper part number 761 589 and revised through May 1983. It covers airframe serial numbers 34-7570001 through 34-8170092, spanning the 1975 through 1981 model years.

Every major section of the aircraft is broken down into exploded-view illustrations with corresponding parts listings. Each listed part carries a figure and index number, Piper part number, special-use code where applicable, nomenclature, quantity required, and the specific serial number ranges affected. That structure makes it possible to confirm whether a given part is correct for your particular Seneca II before you order.

Each illustrated figure is followed by a parts listing that provides the figure and index number, part number, code letter, nomenclature, number required, and serial number applicability. The parts listings use an indentation system to show assembly relationships — unindented items are main assemblies that include the indented components below them. Code letters in the listings indicate special ordering conditions, such as parts that must be purchased from a specific Piper facility.

The catalog also includes a numerical index at the rear, allowing you to locate any part number quickly and find its associated figure and index number.

What This Seneca II Parts Catalog Covers

The PA-34-200T Seneca II Parts Catalog is organized around the complete airplane. Figure 1 provides an overview of the aircraft with callouts to each major group, and subsequent figures break the aircraft down into every major system and subsystem.

For the airframe, the wing group covers the complete wing installation including leading and trailing edges, ailerons, and flaps. The fuselage group is the most extensive, documenting everything from the nose cone through the aft fuselage section, including all door assemblies, interior finishing, seats, and environmental systems. The tail surfaces group covers the stabilator, fin, and rudder assemblies with their associated trim tabs and hinges.

For the power plant, the catalog documents the Continental TSIO-360-EB and LTSIO-360-EB engine installations, both Hartzell two-blade and McCauley three-blade propeller assemblies, engine baffles, cowl assemblies, cowl flaps, engine controls, and the complete nacelle installation.

The chassis group covers the nose gear, main gear, wheels, brakes, and the hydraulic system that actuates the landing gear doors. Detailed exploded views show every component from the gear truss assemblies down to individual bushings, bearings, and hardware.

Electrical and electronics coverage includes the complete electrical system, instrument panel electrical, strobe lights, external power supply, landing light, propeller deicer systems, heated glass panel, autopilot installations, ELT systems, radio antenna systems, audio selector, radar altimeter, radar system, and encoder installations.

Why This Illustrated Parts Catalog Is Useful

When maintaining, restoring, or repairing a Seneca II, identifying the correct part is the first step. This catalog gives you the exploded-view illustration that shows how components fit together, the part number to order, the quantity required, and the serial number range that confirms compatibility with your specific aircraft. Without it, you are left guessing or relying on potentially outdated parts listings.

The catalog covers both early and late serial number ranges, with separate part numbers shown where Piper made running changes across the production run. This means you can look up the exact part for your aircraft rather than assuming a single part number applies to all Seneca IIs.

How to Use This Parts Catalog

The catalog is organized so you can work from either direction — find the illustration that shows your system, locate the part visually, then match the index number to the parts listing for the part number and applicability. Or if you already know the part number, use the numerical index at the rear to find its figure and index location.

The serial number column is particularly important. Where a part changed during production, the catalog lists separate part numbers with the specific serial number ranges affected, so you can be confident you are ordering the right component for your aircraft.

Note: This catalog is intended for parts identification only and should not be used for rigging or installation purposes.
