Built of
aluminium
The airframe is aluminium: sheet metal over a riveted frame, the way most aircraft have been built since the 1940s. The original 1948 170 had fabric-covered wings; the 170A and 170B are all-metal. This is how the Cessna 170 family is built; the FAA does not record construction for each aircraft, and the type certificate data sheet is the authority for this one.
