The Porterfield Aircraft Corp. was founded in 1934 by E.E. Porterfield, once president of the American Eagle Aircraft Corp. In the following year, it began producing the Porterfield two-seat monoplane. Designations included the 35-70 (70-hp Le Blond), 35-90 (90-hp Warner Scarab Junior), 35-65 (65-hp engine), and 35-75 (75-hp engine). The company introduced the CP-series in 1939, which included the CP-50, CP-55, CP-65, FP-65, and LP-65. The initials refer to the type of engine—Continental, Franklin or Lycoming—and the numbers refer to the horsepower. The Collegiate CP-65 was the most popular of the series. A substantial number of these two-seat training planes are still in flyable condition.
