GY-90 Mowgli
Role	civil utility aircraft
National origin	France
Manufacturer	SITAR for homebuilding
Designer	Yves Gardan

The SITAR GY-90 Mowgli[1] was a light aircraft designed in France in the late 1960s and marketed for homebuilding.[2][3][4] Designer Yves Gardan intended it to be a smaller and simpler version of his Bagheera,[2][3][4] a conventional low-wing, cantilever monoplane with fixed tricycle undercarriage and a fully enclosed cabin.[2][3] However, although the Bagheera had seating for up to four people in 2+2 configuration,[2] the Mowgli had no rear seat and could seat only two people, with space behind the seats for luggage.[2][3][4] Like the Bagheera, construction was of metal throughout.[2] The Mowgli was designed to use either a 67-kW (90-hp) or 75-kW (100-hp) Continental flat-4 engine.[2]

The Mowgli was available in the form of plans and kits,[3][4] and plans continued to be available even after SITAR closed in 1972.[5] The first example was expected to fly in 1970.[2]

Notes

1. SITAR marketed three designs: the Bagheera, the Mowgli, and the Sher Khan. The GY-100 Bagheera was named after Bagheera, a character in Rudyard Kipling's The Jungle Book (The Illustrated Encyclopedia of Aircraft, p.2857). Mowgli and Sher Khan are characters in the same book.
