The JPM 03 Loiret is a French amateur-built aircraft that was designed by Jean-Pierre Marie and produced by Avions Jean-Pierre Marie (JPM) of Le Mesnil-Esnard. The aircraft is a development of the JPM 01 Médoc and is supplied as plans for amateur construction.[1][2]

Design and development

[edit]

The Loiret features a cantilever low wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.[1][2]

The aircraft is made from wood with its flying surfaces covered in doped aircraft fabric. Its 7.72 m (25.3 ft) span wing has an area of 8.49 m2 (91.4 sq ft) and mounts flaps. The Loiret was designed specifically to use only the 85 hp (63 kW) Jabiru 2200 four-stroke powerplant.[1][2]

The aircraft can be built with a single-piece wing or a three-piece folding wing. With the wings folded the resulting width is 2.36 m (7.7 ft), permitting ground transport or storage.[3]
