Swallow TP

The Swallow TP was a trainer aircraft produced by the Swallow Airplane Company in the United States from 1928.

Design and construction
The TP was a simple and rugged biplane design with room for an instructor and student in tandem open cockpits. The fuselage was made from welded steel tubing, faired to shape and then fabric covered. The wings were typical of the day with Spruce spars, spruce & plywood ribs with fabric covering. Built to be easy to fly, and for ease of maintenance, the Swallow TP was quite popular with nearly 200 being built. Initially the TP was offered with the ubiquitous Curtiss OX-5. Later, it was offered with a choice of a Siemens-Halske, Kinner, or Warner engines. Most customers opted for the OX-5 which was the cheapest.
