In the middle 1930s Peru sought to expand its air arm and selected the British-designed Bristol Beaufort to serve as a light bomber and general reconnaissance aircraft. However, a decision was made to power the Peruvian aircraft not with the Bristol Taurus sleeve valve radial engines of the original design but with Junkers diesel aircraft engines obtained in Germany, which were expected to give the Peruvian variant enhanced performance. Factory tests in Dessau were satisfactory, but the complex engines failed to live up to expectations in the Andean conditions in which the aircraft would operate; reliability was also an issue due in large measure to loss of spares support from the manufacturer.
To address the issue technicians at the recently formed Empresa Nacional de Aviación tested several alternative engines and selected the Avia-Minerva Faucon I 14-cylinder air-cooled radial piston engine to replace the Jumo diesels; tests proved successful – the Faucon engine was much more reliable and suited to Peruvian conditions. Between 1940 and 1942 the 28 Beauforts in the Peruvian inventory were re-engined and refurbished at the Limatambo works with the assistance of Belgian and Czech technicians.
With the success of the refurbishment program a decision was made to acquire from Britain additional Beaufort airframes, as well as a large quantity of spares, from surplus stocks of the Royal Air Force and additional Faucon engines in Belgium. Fifty airframes were eventually acquired and brought up to Peruvian standards with the Faucon engine. The Fuerza Aérea del Perú has applied the sobriquet Canastero to the modified aircraft.
