Piaggio P-166DL3
The Piaggio P.166DL3 is the turboprop-engined evolution of Piaggio's distinctive twin pusher-engine utility aircraft, itself derived from the P.136 amphibian and recognisable by its high-mounted, rearward-facing propellers. Designed by Alessandro Mazzoni, the DL3 first flew on 3 July 1976 with 600hp Lycoming LTP101 turboprops replacing the earlier piston engines, and production totalled 36 aircraft for roles including the Italian Air Force, Coast Guard, and Alitalia's flying school. A dedicated maritime-surveillance version, the P.166DL3/SEM, was built in greater numbers still for the Italian Coast Guard and Guardia di Finanza, patrolling Italian waters and monitoring pollution from the air.
