The Boulton Paul P.112 was a design for a basic trainer to replace the Percival Prentice.
The Prentice had been designed in response to Specification T.23/43, and had competed against the Boulton Paul P.106, a low winged monoplane with a large glazed canopy. Once in service the Prentice had proved unsatisfactory, and a new specification, T.16/48, was produced for an aircraft to replace the Prentice. This was to be a three-seat basic trainer.
Boulton Paul produced two designs, both similar to their successful P.108 Balliol. The P.112 was a low winged monoplane, with a fixed undercarriage. Two engines were offered - the Alvis Leonides IVM in the P.112 or the Pratt & Whitney Wasp R-1340 in the P.112A. It had a fixed undercarriage with wheel spats. A mock-up was built but the design didn’t reach the prototype stage.
The P.112 was rejected in favour of the de Havilland Chipmunk.
