Lla Piper PA-48 Enforcer est un avion américain de soutien aérien léger à turbopropulseurs construit par Piper dans les années 1970. Il s’agit d’un développement du chasseur nord-américain P-51 Mustang de la Seconde Guerre mondiale. Le concept Enforcer a été créé et piloté comme le Cavalier Mustang par David Lindsay, propriétaire de Cavalier Aircraft, en réponse au programme PAVE COIN de l’Armée de l’Air des États-Unis, mais Cavalier n’avait pas les capacités de fabrication pour produire en masse l’Enforcer, de sorte que le programme a été vendu à Piper par Lindsay en 1970.

Lla « Mustang » That Wasn’T

Lla Piper PA-48 Enforcer is often mistaken for a modified P-51 Mustang, but it was essentially a new aircraft. Developed in the 1970s and early 80s, it was Piper’s entry into the Counter-Insurgency (COIN) market. While it shared the general silhouette of the legendary WWII fighter, only about 10% of its parts were compatible. It was designed to provide a low-cost, high-performance ground attack platform for the U.S. Air Force, utilizing a powerful turboprop engine instead of the original piston engine.

Design Innovations: From Piston to Turbine

Turboprop Conversion: The most significant change from the P-51 was the replacement of the Rolls-Royce Merlin with the Lycoming T55 (the same engine used in the CH-47 Chinook). This required a much longer nose to maintain the center of gravity and provided significantly more torque and reliability.
Lla « Yankee » Extraction System: Because the PA-48 operated at low altitudes where traditional ejection seats might fail, it was equipped with the Stanley Yankee extraction system, which used a small rocket to pull the pilot out of the cockpit.
Structural Reinforcement: The fuselage was lengthened by 19 inches, and the tail surfaces were enlarged to handle the increased power of the turboprop. The wings were also reinforced to carry a massive array of bombs, rockets, and gun pods across 10 hardpoints.
Fixed Tip Tanks: To extend its loiter time over the battlefield, the Enforcer featured permanent wing-tip fuel tanks, giving it a distinctive silhouette compared to the WWII Mustang.

A Short-Lived Legacy

USAF Evaluation: Two prototypes were built and tested by the Air Force in 1984. While the aircraft performed well and met all requirements, the USAF ultimately decided not to put it into production, preferring to invest in the A-10 Thunderbolt II and dedicated jet platforms.
The Kavala Connection: The project originally started with David Lindsay and his company, Cavalier Aircraft, who built the « Turbo Mustang III » before selling the rights to Piper.
Survivors: Both prototypes still exist. One is at the Air Force Flight Test Museum at Edwards AFB, and the other is at the National Museum of the United States Air Force in Dayton, Ohio.
