The Waco A series is a range of light American-built twin side-by-side seater sporting biplanes of the early 1930s.
The Waco A series was 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 1000NaN0 Kinner engine and the later UBA with a 2100NaN0 Continental powerplant.[1]
The PLA "Sportsman" of 1933 introduced a longer wider fuselage and a higher useful load and had a 1700NaN0 Jacobs LA-1 radial engine. The last model in the series was the ULA, also of 1933, with a 2100NaN0 powerplant.[2]
The A series was bought mainly by private pilot owners with a sporting inclination. Relatively few were produced and the type survives in small numbers in 2009. A PBA is on display in the Historic Aircraft Restoration Museum at Dauster Field near St Louis, Missouri.
