This B-26B B-26C Illustrated Parts Breakdown manual covers the complete aircraft divided into seven main groups: Wing, Empennage, Fuselage, Power Plant, Electronics, Armament, and Alighting Gear. Every installation, assembly, and part is listed with its part number, description, quantity per assembly, and usable on code. Component parts are indented to show their relationship to the installation or assembly. Attaching parts such as bolts, screws, washers, and nuts are listed in the same column immediately following the parts they attach. The Numerical Index is compiled according to the numerical part number filing system, with an order of precedence of space, dash, letters A through Z, and numerals 0 through 9. Stock numbers include Air Force Class Code, Federal Supply Classification (FSC) Code, and Converted-In-Place (CIP) Code formats. Source coding definitions cover Code P (parts under inventory stock control), Code P1 (difficult or uneconomical to manufacture), Code M (manufacture locally), Code A (assemble), Code X (impracticable for manufacture or procurement), and unprocured manufactured or stocked parts.

What This Manual Enables You To Do

With this B-26B B-26C Illustrated Parts Breakdown manual, you can identify and order correct spare parts for any system on the aircraft. The group assembly structure lets you trace from a major installation down through each assembly and individual component, and the numerical index lets you look up any part number and find its exact location in the parts list. The exploded view illustrations show how parts fit together, and the quantity data tells you how many of each item is required per assembly. This is essential for maintenance, restoration, and parts procurement on the B-26B, B-26C, TB-26B, TB-26C, and RB-26C aircraft.

Why This Manual Matters

Using the correct part numbers and understanding assembly relationships prevents ordering errors and ensures the right components are installed. The T.O. 1B-26B-4 parts breakdown gives you the exact part number, description, and usable-on code for every item, plus the vendor codes and manufacturer addresses you need to source components. The numerical index and stock number information help you cross-reference between Air Force stock numbers and manufacturer part numbers. This level of detail is critical for anyone maintaining or restoring these aircraft.
