UBA
 
The Waco A series is a range of light American-built twin side-by-side seater sporting biplanes introduced in 1932 as an affordable private-owner aircraft with cross-country range and baggage capacity and a more sporting image than the larger Waco F series. The A series offered a number of engine options which had varying sub-designations. The power range lay between the KBA with a 100 hp (75 kW) Kinner engine and the later UBA with a 210 hp (157 kW) Continental powerplant.

The PLA "Sportsman" of 1933 introduced a longer wider fuselage and a higher useful load and had a 170 hp (127 kW) Jacobs LA-1 radial engine. The last model in the series was the ULA, also of 1933, with a 210 hp (157 kW) powerplant.
