The New Standard D-25 was a 5-seat agricultural and joy-riding aircraft produced in the US from 1928.

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