The Tecnam P92 Echo and Tecnam P92 Eaglet are Italian high-winged, light aircraft, designed by Luigi Pascale and built by Tecnam of Naples.[2][3]
Design and development
The P92 design dates to 1960, but versions comply with the Fédération Aéronautique Internationale microlight rules and US light-sport aircraft rules. It features a strut-braced high-wing, an enclosed cabin with two seats in side-by-side configuration accessed by doors, fixed tricycle landing gear or conventional landing gear and a single engine in tractor configuration.[3]
The aircraft is made of sheet and tubular aluminum. Standard engines available are the 100 hp (75 kW) Rotax 912ULS, 115 hp (86 kW) Rotax 914 and the 100 hp (75 kW) Lycoming IO-233 four-stroke powerplants.[3]
The P92 Eaglet was introduced in 2008. It employs a cockpit section made of steel tubing covered in sheet aluminum and a monocoque tail cone. It also features a new wing design, a rear window and a cabin that is 117 cm (46 in) wide.[3]
The design is an accepted Federal Aviation Administration special light-sport aircraft.[4]
