In 1935, parallel to the light sport aircraft CNA 15, the Italian company Compagnia Nazionale Aeronautica (CNA) developed the light multipurpose aircraft CNA 25. This aircraft was designed to offer versatility for various roles, building upon CNA’s existing aeronautical expertise.
Design and Powerplant
The CNA 25 was configured as a four-seater high-wing monoplane, a design choice common for utility aircraft of its era. It was powered by an in-house developed six-cylinder engine, the CNA C.VI IRC.43, which delivered a respectable 150 horsepower, providing adequate performance for its intended purpose.
Public Presentation and Outcome
The aircraft made its public debut alongside the CNA 15 at the Second International Salon in Rome in 1937, aiming to showcase Italian aviation innovation. However, its flight characteristics as a high-wing monoplane were found to be slightly inferior to those of a low-wing configuration. Consequently, the project did not receive further development, limiting the CNA 25’s production and operational history.
