KEYSTONE LB-14

Posted 6/25/2009 Printable Fact Sheet

The Keystone LB-14, like the LB-13, was designed as a modification of the basic LB-10A design. The original engines were to be replaced by Pratt & Whitney GR-1860 radials; however, the Light Bomber (LB) designation was dropped in 1930 and the order was changed to Keystone Y1B-5s. The Y1B-5 design was changed to incorporate another engine, in this case the Wright R-1750-3.

Three Y1B-5s (S/N 30-354 to 30-356) were built and another 27 aircraft were diverted from the Army Air Corps order for LB-10As (B-3A).
