Design and development

The P.112 was developed from the successful Boulton Paul Balliol, an advanced trainer powered by a Rolls-Royce Merlin piston engine, sharing the same fuselage as the Balliol but with new high aspect ratio wings and a non-retractable spatted undercarriage of 15 ft 2 in (4.62 m) track.[1][2] The trainer was equipped with three seats, similar to the Balliol and looked so like the earlier aircraft that the image in the brochure was actually a retouched Balliol T.1.[3] However, the Royal Air Force preferred the smaller de Havilland Canada DHC-1 Chipmunk to the P.112 and so no production ensued.[3]

Variants
P.112
Baseline design for the elementary trainer, powered by an Alvis Leonides LE.4M
P.112A
The same design equipped with a Pratt & Whitney R-1340 Wasp engine. This and the Balliol T.2A, were the only Boulton Paul aircraft offered with American engines.[3]
