Early Developments and Variants

The smallest variant of the aircraft, the CA-3 Airsedan, appeared in 1928. It was a three-seat biplane, equipped with a 225 hp Wright J-5 engine. In this and the following year, five more sub-variants emerged: the CA-3A, the somewhat smaller CA-3B Junior Airsedan (with a 110 hp Warner Scarab engine), the CA-3C Sport Airsedan, the CA-3W (with a Pratt & Whitney Wasp), the CA-3D Sport Airsedan (with a 300 hp Wright J-6), and the CA-3E Sport Airsedan (with a 225 hp Packard DR-980 diesel engine).

Expansion and Advanced Models

From 1927, a five-seat version of the aircraft, the CA-5, was produced with a Wright J-5 engine (also released in an enhanced comfort variant, the CA-5A). In 1929, a six-seat version, the CA-6, was introduced with a Wright J-6 engine. Like the CA-3, the CA-6 was also built in five modifications, differing mainly in engines: the CA-6A (Pratt & Whitney Wasp 420 hp), CA-6B (Pratt & Whitney Wasp 450 hp), CA-6D (a conversion of the CA-3D), CA-6J (five-seat with Pratt & Whitney Wasp 300 hp), and C-6W (four-seat with Pratt & Whitney Wasp 420 hp).

The final version of the aircraft was the eight-seat CA-8 Senior Airsedan, powered by a 450 hp Pratt & Whitney Wasp engine. It was also produced in two modifications: the CA-8A with a 525 hp Wright Cyclone and the CA-8B with a Pratt & Whitney Hornet of the same power.

Notable Achievements and Expeditions

The Airsedan gained fame in various competitions and long-distance flights. For instance, in 1929, pilot Loren Mendell won first prize in the Oakland-Cleveland Air Derby with an Airsedan. The aircraft named “Spokane Sun God” participated in a non-stop flight across the USA the same year, using in-flight refueling over 120 hours. Sadly, the CA-5 named “Miss Doran” went missing in the infamous 1927 Dole Race from California to Hawaii.
