Piper only made about 200 of their PA-14s, all of them in the late 1940s. If you get a chance to fly one, you know how unique that opportunity is.
Rare planes, however, require you to be prepared. Sometimes they simply don’t share much in common with other planes, even those from their production era. So, be as ready as possible by getting your hands on a reproduction Aircraft Owner/Information Manual (AIM), also called a Pilot Operator’s Handbook.
Pilot Mall has plenty in stock. They are copied from originals using the finest printing technology available. Furthermore, they have all the original data and information about the PA-14.
They are not an FAA-certified replacement for your lost or damaged manual, though.
