The Preceptor N3 Pup is a family of ultralight, tube-and-fabric, high-wing, homebuilt aircraft.

[1][2][3][4][5][6] The company was operating on a limited basis, actively selling plans online,[7] but seems to have gone out of business in 2016.

[8] Designed to meet FAR 103 Ultralight Vehicles standards, the N3 Pup can accept various lightweight four stroke engines of between 37 and 60 hp (28 and 45 kW).

If built to specifications with minimal additions, it can meet the requirements for a FAR 103 ultralight aircraft, with an empty weight of 254 lb (115 kg).

[5] A N3 Pup named "Citabriette" -- modified to look like a Citabria -- won the Grand Champion Ultralight award at the EAA Oshkosh airshow 1988.
