Development

Designed by Charles H. Day, the D-25 was developed from his four-passenger D-24 which was equipped with a 180 hp (134 kW) Hispano-Suiza E eight-cylinder radial engine and built in Paterson, New Jersey. This was underpowered, and production switched to a 220 hp (164 kW) Wright J-5 engine, the new model being renamed the D-25. It received its type certificate (No.108) in February 1929. The retail price was $9,750. [1] Some of the existing D-24s were converted to D-25 specification, including one by its owner, famous barnstormer Johnny Miller. [2]

Construction

The D-25 was constructed primarily from Duralumin and wood. Duralumin stringers were used for the fuselage, with duralumin sheets riveted onto them. Unlike the fuselage, the wings were mostly of wood, with a main spar made of spruce, basswood for the stringers, and plywood for reinforcement, along with fabric coverings for the wing area and control surfaces. The D series was quite distinctive in having sesquiplane wings with the upper wing, of much bigger span and chord, supported on tall cabane and interplane struts.

Operational use

Seating for four passengers was provided in the open front cockpit, described as "chummy", with the pilot in the single seat open rear cockpit. Variations in seating arrangement reflected the role of the different variants. The rugged structure gave the New Standard Ds a long-life, leading to the respectable number that survived the abuse of joy-riding, mail carrying and crop dusting for many years. New Standard ceased trading in 1930 but production restarted with around nine being built from 1933 through 1937, most of these being used for crop dusting. [1]

Two D-25As that had been confiscated from smugglers were acquired by the US Coast Guard in 1935, designated NT-2. [3]
