This Cargo pod is designed to allow additional cargo outside of the cabin of a Pilatus PC-6 airplane & hang on a hard point on the wing. It is 115" long & 16" in diameter. They can be easily removed or installed & are interchangeable with fuel tanks when they are needed. The labels are used to show how to load it properly. They also show how to install & remove the wooden bulkheads (the parts with the round label on the inside).
I used two different CAD (Computer Aided Design) packages to allow both drawings & words. After a little practice they printed perfectly.
