Description

Piper PA-44-180 & PA-44-180T Seminole Illustrated Parts Catalog 761 663

This Piper PA-44-180 and PA-44-180T Seminole Illustrated Parts Catalog is the complete factory parts reference for both the normally aspirated and turbocharged Seminole light twins. Issued by Piper Aircraft Corporation under catalog number 761 663, it carries the April 28, 1978 original publication plus every revision released through October 12, 2015. Every airframe assembly, powerplant installation, system component, and avionics accessory used across the Seminole’s 1979 through 1993 production appears here with Piper part numbers, illustrated figures, and the exact airplane serial numbers each part fits. If you are ordering, replacing, or verifying a part for a Seminole, this is the document the parts counter uses.

What Is Inside This Piper PA-44-180 Parts Catalog

The Piper PA-44-180 & PA-44-180T Seminole Illustrated Parts Catalog divides the entire aircraft into fourteen major sections. Sections I through XII hold every replacement part for the complete airplane – wings, fuselage, empennage, landing gear, cabin, instruments, powerplants, fuel system, flight controls, hydraulics, environmental systems, and electrical systems. Section XIII is the electronics group covering autopilots, encoders, transponders, emergency locators, radar, and radio/antenna installations. Section XIV, the Miscellaneous Group, contains the placard and exterior stencil illustrations, the optional equipment kit listings, repair kits, and special tools.

Each section is further broken down into individual figures. Every figure consists of one or more illustrated pages showing the assembly in exploded or cutaway view, followed by a parts listing that identifies each item by figure and index number, Piper part number, code letter, nomenclature, quantity required, and the serial numbers affected.

• Numerical Parts Index

Every listing uses the same column layout: figure and index number, Piper part number, code letter, nomenclature, number required, and serial numbers affected. Indented lines show how the parts nest – a single asterisk marks a direct sub-part of the assembly above it, two asterisks a sub-assembly of that sub-part, and so on. Ordering a higher assembly automatically delivers everything indented beneath it; ordering an individual part gets you that item alone.

Code letters beside each part number indicate the specific model, serial range, or option configuration a part applies to. Each code letter is explained on the grid page that immediately precedes its figure, and applies only to that figure’s listing. Because the catalog carries revisions all the way to 2015, many figures show several code variants side by side so early and late aircraft are covered by the same page.

The Numerical Index at the back cross-references every Piper part number in the catalog against the figure and index number where it appears. If you already have a part number, you can jump straight to the illustration without paging through each section – a real time saver on a catalog this size.

Serial Number Coverage

The catalog’s serial-number columns and code explanations identify which parts were originally fitted to which airplanes. This single document spans the entire Seminole production run:

• PA-44-180 Seminole, 1979 models: 44-7995001 through 44-7995329
• PA-44-180 Seminole, 1980 models: 44-8095001 through 44-8095027
• PA-44-180 Seminole, 1981 models: 44-8195001 through 44-8195026
• PA-44-180T Turbo Seminole, 1981 models: 44-8107001 through 44-8107066
• PA-44-180T Turbo Seminole, 1982 models: 44-8207001 through 44-8207020
• PA-44-180 Seminole, 1989 models: 4495001 through 4495009
• PA-44-180 Seminole, 1990 models: 4495010 through 4495012
• PA-44-180 Seminole, 1993 models: 4495013

Piper switched from a four-set serial numbering system (type certificate, model year, model code, sequence) to a three-set system (type certificate, model code, sequence) partway through production. This catalog documents both formats, so you can identify a part for any Seminole regardless of when it left the factory.

Engines and Propellers Referenced

The powerplant and propeller figures document the Lycoming engines and Hartzell propellers Piper installed on the Seminole:

• Lycoming O-360-EIAD and LO-360-EIAD – early PA-44-180 models
• Lycoming T0-360-E1A6D and LT0-360-E1A6D – turbocharged PA-44-180T models
• Lycoming O-360-A1H6 and LO-360-A1H6 – PA-44-180 models from serial 4495001 onward
• Hartzell two-blade HC-C2Y(K,R) series propellers – left and right
• Hartzell three-blade HC-C3YR series propellers – left and right

Why This Piper Seminole Parts Manual Matters

Piper part numbers are not always intuitive, and many parts changed between model years or serial ranges. Ordering the wrong version is expensive and can ground the aircraft. This parts catalog removes the guesswork: each line tells you exactly what part fits which serial number, which engine variant, and which option configuration. For a mechanic, a shop, a parts specialist, or an owner who prefers to source components themselves, it is the fastest route from a broken item to the correct replacement number.

Because the catalog integrates revisions from 1978 all the way to 2015, it reflects current Piper part numbers and supersessions rather than the original 1978 numbers only – which means the numbers you pull from it are the ones the parts chain recognizes today.
