November 2005- In October of 1958, Piper proposed a twin-engine version of the successful Comanche single. This was not the PA-30 Twin Comanche, planning of which had begun two years earlier but development and production of which would be several years hence (thus the skip in numeric order).

Piper initially planned for the model to be developed in California by Bill Lear, and would furnish a PA-24 Comanche airframe and two 200 hp IO-360 engines. Whether this actually ever happened is not recorded, but in 1962 the PA-30 project was given to San Antonio designer Ed Swearingen.
