The best way to learn about a Piper PA-36 Pawnee Brave is with the yoke in your hands. But before you dive head-first into flight time, you should first get acquainted with the Aircraft Owner/Information Manual, also called the Pilot Operator’s Handbook.
Pilot Mall sells reproductions that are perfect for training and as a reference. They contain all the original manufacturer’s information on the PA-36 series in general.
They are not, however, FAA-certified replacements. That’s because they don’t contain specific information about your individual aircraft’s equipment, which can vary from one PA-36 to another.
