The 1925 D-25 received ATC 108 and was priced at $9,795. About 45 were built. ATC 2-542 was issued in 1937.
In 1928 the Gates-Day Aircraft Corporation became New Standard Aircraft Corporation, and the following year produced the White New Standard D-25 tandem, open-cockpit four-seat biplane, developed from the Gates-Day GD-24.
With the pilot seated behind and four passengers in front, all in open cockpits, it is a large biplane by any standards.
Designed by Charles H Day, production of D¬25s began at the Gates Day plant at Peterson, New Jersey in 1928 and when production ceased two years later about 65 of the type had been delivered a few were built during the 1930s as crop dusters.
Jones Aircraft Corp was formed in 1935 by Ben Jones after acquiring rights in D-25 biplane previously built by the New Standard Aircraft Company. Jones built 10 of these in 1938, in factory at Schenectady, New York.
The 1929 D-25A (ATC 224) was powered by a 225hp J-6 for an increase in load. Priced at $7,990, five were built, NC33K, NC38K, NC150M, NC930V, NC9190, the next-to-last of which was modified with 300hp J-6 as D-25B (see White D-25B).
The D-25X was a modification of D-25A, registered N37K c/n 203.
