Development and Design

In 1929, the light transport flying boat Loening Commuter was completed, powered by a 300 hp Wright J-6 engine. The aircraft was similar to the Sikorsky S-39, with the exception of its configuration: the Sikorsky flying boat was a monoplane, while the Commuter was a biplane.

Corporate Merger and Redesignation

Following the merger of Keystone and Loening firms in 1931, the aircraft’s designation changed to Keystone-Loening K-84 Commuter. This redesignation reflected the combined corporate identity of the newly formed entity.

Production and Variants

A total of 31 units of the flying boat were produced until 1932. One of these, specifically NC374V, underwent modification in 1930 into the K-84W variant, equipped with a 300 hp Pratt & Whitney Wasp Junior engine.
