The Piper PA-48 Enforcer was a turboprop powered light close air support aircraft built by Piper in Lakeland, Florida in the 1970s. It was the ultimate development of the World War II-era P-51 Mustang fighter. The Enforcer concept was originally created and flown as the Cavalier Mustang by David Lindsay, owner of Cavalier Aircraft, in response to the United States Air Force PAVE COIN program, but Cavalier did not have the political clout or manufacturing abilities to mass-produce the Enforcer, so the program was sold to Piper by Lindsay in 1970.

In 1968, Cavalier Aircraft owner/founder David Lindsay began developing a highly modified version of the Cavalier Mustang for use as a counter-insurgency aircraft. Cavalier initially mated a Rolls-Royce Dart 510 turboprop to a Mustang II airframe. This privately funded prototype was also intended for the same CAS/COIN mission that the Mustang II was built for. The Turbo Mustang III had radically increased performance, along with an associated increase in payload and decrease in cost of maintenance, and was equipped with Bristol ceramic armor to protect the engine, airframe and pilot. Despite numerous sales attempts to the United States Air Force, neither the U.S. military nor any foreign operators purchased the Turbo Mustang III.

Seeking a company with mass production capability, the Turbo Mustang III, renamed the "Enforcer," was sold to Piper Aircraft in late 1970. Cavalier Aircraft Corp. was closed in 1971 so the founder/owner, David Lindsay, could help continue develop the Enforcer concept with Piper. Piper was able to lease a Lycoming T-55L-9 engine from the USAF (the engine Lindsay wanted initially) and flew the aircraft some 200+ hours. In 1984 with a $US12 million appropriation from Congress, Piper built two new Enforcers, giving the new prototypes the designation PA-48. These aircraft were evaluated by the USAF, but flown only by Piper test pilots.
