Construction

New Standard D-25 New New Standard for Ted Davis

The D-25 was constructed from Duralumin angles channels and tees bolted and rivetted together for the fuselage and Spruce spars with bass wood and plywood built-up ribs, all fabric covered. 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.
