The Harlow Aircraft Company in Alhambra, California, designed a version of the PJC-2 as a tandem two-seat training aircraft.[1] The PC-5 had a revised fuselage with dual controls.[1] The aircraft first flew in July 1939 but it failed to interest the United States Army Air Corps. Howard Hughes' business partner, J.B. Alexander, backed the project and had flown in early examples of the aircraft.[2] Harlow licensed the manufacturing rights to the PC-5 to Cub Aircraft of Canada during the wartime buildup.[3] Only five aircraft had been built when the company was taken over by the Intercontinent Corporation. Components for 50 aircraft were supplied to the Indian company Hindustan Aeronautics, who were to assemble the aircraft for use by the Royal Indian Air Force as the PC-5A.[3] The first PC-5A flew in August 1941,[4] but it is not known how many were assembled and flown.

Using an engineering team brought in by Intercontinental, a cheaper version of the PC-5 was developed and built as the PC-6. The PC-6 wing failed, causing a fatal accident during an early test flight.^{[citation needed]}
