Historical Note
The Piper PA-18 Super Cub stands as one of aviation's most enduring and beloved designs. Introduced in 1949 as an evolution of the Taylor/Piper J-3 Cub, the Super Cub featured a more powerful engine, improved performance, and enhanced utility that made it the definitive light aircraft for bush flying, agricultural work, and military liaison duties. Powered by engines ranging from 90 to 150 horsepower, the Super Cub's exceptional STOL performance, rugged construction, and forgiving handling characteristics earned it a legendary reputation worldwide.
The PA-18 served extensively with the U.S. military as the L-18 and L-21, performing observation, liaison, and training duties during the Korean War and beyond. Over 10,000 Super Cubs were produced between 1949 and 1994, with thousands remaining in active service today for bush flying, glider towing, pipeline patrol, fish spotting, and recreational flying. The Super Cub's influence extends far beyond its production numbers—it established the template for modern bush aircraft and inspired countless derivatives and reproductions.
Today, the PA-18 Super Cub remains one of the most sought-after vintage aircraft, with active restoration projects, STC modifications (including CubCrafters' extensive upgrade programs), and a thriving enthusiast community. These original engineering drawings provide invaluable reference for restorers maintaining airworthy Super Cubs and researchers studying this iconic design.
