The Piper PA-48 "Enforcer" is a turboprop powered light close air support/ground-attack aircraft built by Piper Aircraft Corp. Lakeland, Florida. It was the ultimate development of the original World War II North American P-51 Mustang. The Enforcer concept was originally created by Cavalier Aircraft in response to the US 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 in 1970.

Flight testing and evaluation

In 1971 Piper built two Enforcers by heavily modifying two existing P-51 Mustang aircraft and fitting them with Lycoming T55-L9A turboprop engines (along with numerous other significant modifications). One airframe was single seat (called the PE-1 and FAA registered N201PE) and the other was a dual-control aircraft (called the PE-2, registered N202PE). Prior to the Pave COIN evaluation, N202PE was lost in a crash off the Florida Coast. Although the Enforcer performed well in Pave COIN, Piper failed to secure a United States Air Force contract.

For another eight years Piper lobbied Congress to force the USAF to officially re-evaluate the Enforcer. Eventually in the 1979 defense bill $11.9 million was allocated for Piper to build two new prototypes and for the USAF to perform another flight evaluation. Since the Enforcer was never in the Air Force inventory, it was not given an official military designation and did not receive an Air Force serial number. Instead, it carries the Piper designation PA-48 and Federal Aviation Administration (FAA) registration numbers N481PE and N482PE.

End of the program

By the time the PA-48s were completed, they shared less than 10 percent of their structure with the P-51. The two PA-48s were tested during 1983 and 1984 at Eglin AFB, Florida and Edwards AFB, California. As in the Pave COIN tests of 1971, the PA-48s were found to perform well in their intended role, but the USAF again decided not to purchase any.

Survivors

Of the prototype aircraft produced, three of the four still exist. The original PE-1 is disassembled and in storage. One of the PA-48s, N482PE, awaits restoration at Edwards Air Force Base. N481PE (pictured above) has been fully restored and resides in the "Prototype Hangar" at the National Museum of the United States Air Force at Wright-Patterson Air Force Base near Dayton, Ohio.
