Development and design

The HA was a two-seat biplane with a central float and balancing floats on the wingtips. The fuselage was wood with a fabric covering. The plane was powered by a Liberty 12 engine in the nose. The prototype was ordered in December 1917, and its first flight was on 21 March 1918. During testing the aircraft proved very unstable, with an overly heavy tailplane. The aircraft was destroyed in a crash.[1]

Two more prototypes were ordered, designated HA-1 and HA-2. the HA-1 was constructed of salvaged parts from the original, but its tailplane and radiator were redesigned, and its wings were moved further aft. The HA-1 caught fire during a flight. The HA-2 had a wider wingspan, and performed better, but as the war was almost over, no production order was received.[1]

Operational history

Three landplane versions were used as Mail planes.[1]
