Description

Complete Airframe Parts Breakdown for Piper Cheyenne Turboprops

The 1974-1984 Piper Cheyenne PA-31T PA-31T1 PA-31T2 Parts Catalog (Card 1) is the foundational structural parts reference for Piper turboprop aircraft operators, maintenance facilities, and certified repair stations. Published under Piper Aircraft Corporation publication part number 753 825 and updated through the October 15, 1997 interim revision, this catalog provides authoritative part identification, exact part nomenclature, exploded structural illustrations, and meticulous aircraft serial number effectivity ranges. Whether maintaining an early 1974 PA-31T Cheyenne, a factory PA-31T Cheyenne II, a refined PA-31T1 Cheyenne I or Cheyenne IA, or a stretched-fuselage PA-31T2 Cheyenne II XL, this Piper Cheyenne parts catalog supplies the verified factory numbers required to source authentic airframe components and mounting hardware.

Card 1 Scope & Structural Focus

This volume represents Card 1 of 5 in the official Piper Aerofiche parts documentation system for the Cheyenne family. It provides exhaustive coverage of Section I: Wing Group and Section II: Fuselage Group through Figure 27 (Emergency Exit Window Installation), alongside factory ordering rules, standardized exterior Titanine polyurethane paint finishes, and manufacturer identification plate decoding. While later card sets encompass tail surfaces, cabin furnishings, landing gear hydraulics, powerplants, and electrical distribution, this 1974-1984 Piper Cheyenne PA-31T PA-31T1 PA-31T2 Parts Catalog (Card 1) delivers complete technical detail for primary airframe assemblies, wing ribs, spars, skin panels, cabin pressure bulkheads, entry doors, floorboards, and windshield installations.

Airframe Station & System Architecture Highlights

The illustrations within this PA-31T1 Cheyenne I parts list and PA-31T2 Cheyenne II XL catalog reflect the precise engineering differences between airframe generations. The manual details the specific forward fuselage stretch of the Cheyenne II XL, which relocates the forward pressure bulkhead from Station 81 to Station 57 and introduces unique fuselage skins, ECS ram air scoops, and extended longitudinal beams. It thoroughly covers pressurization integrity components, including multi-pin hermetic bulkhead connectors (19, 24, 37, 43, and 63-pin configurations), elastomeric O-ring seal retainers, and flight control cable pressure seals. Wing structural assemblies depict the exact rib stations from root Station 30 out to tip Station 239.62, accommodating both standard wing configurations and factory wing-tip fuel tank installations.
