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]
