The Porterfield Collegiate is an American-built two-seat training and touring monoplane built by the Porterfield Aircraft Corporation of Kansas City.
Developed originally as the Porterfield Zephyr, it is a light-weight version of the earlier Model 35 Flyabout for use a pilot trainer. Powered by a 40hp (30kW) Continental A-40 engine it was later re-designated the Porterfield CP-40.
To improve performance the engine was replaced with a 50hp (47kW) Continental A50-4 engine and re-designated the CP-50 Collegiate. It is a braced high-wing monoplane with a tail skid fixed landing gear. The two bracing struts run in parallel from the bottom of the fuselage and the tailplane was fixed to the top of the rear fuselage.
Total production had reached 476 when production ceased in 1942 at the start of American involvement in the Second World War. Over 100 Porterfields remained active with private pilot owners in the United States and other countries in 2001.[2] A number of variants were produced with different engine installations, resulting in a series of model designations.
In 2011 two Collegiates were active in the UK, G-AFZL a 1939 CP-50 and G-BVWY a 1941 CP-65. Others airworthy outside the USA include examples in Canada, Mexico and Argentina. An owners club exists to support the ongoing operation of the type.
