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

Construction

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 off smugglers were acquired by the US Coast Guard in 1935, designated NT-2.^[1]

Survivors

Seven New Standards survived in 2007. Airworthy D-25s include two at Old Rhinebeck Aerodrome Museum, New York, and two that operate joy rides from the Fantasy of Flight at Polk City, Florida. Additionally N930V operates on the west coast as of early 2008 and N9194 was recently completely restored and deemed airworthy again in May of 2009. A D-29 (NT-1) is displayed at the National Museum of Naval Aviation, Pensacola, Florida.
