The Towle TA-2 was an amphibious aircraft based on the Towle WC built for a 1929 round-the world flight.

Development

Thomas Towle was an engineer that had been involved with many early aircraft designs. Having just co-designed the Eastman E-2 Sea Rover and the Towle WC, Towle found funding to create a new entity, the Towle Aircraft Company to produce the TA-2. ^[1]

Design

The TA-2 featured a corrugated aluminum hull. The wings were all metal with internal stiffeners, rather than ribs, based loosely on the Ford Trimotor, which Towle worked on previously. The twin Wright R-540 engines sat on small pylons on top of the shoulder mounted wing. ^{[2] [3]} Two floats were mounted directly below the engine pylons which incorporated the hydraulically actuated landing gear. ^[4] The prototype was originally designed for 165 hp Wright 540 engines. ^[5]

Operational history

The TA-2 was tested in Lake St. Clair on 7 November 1929 by test pilot George Pond and James Bradley. It broke up on takeoff and sank to the bottom of the lake. ^[6] The aircraft appears to have been rebuilt as a Towle TA-2 and was reported to have visited Lympne Airport, Kent, United Kingdom in February 1930. ^[3] The wing from the prototype was salvaged and used on the next iteration, the Towle TA-3.
