The Aerocraft 2AS is a tandem-seat training aircraft developed from the Kinner Sportwing.


Design and development

Timm formed the Wally Timm Company in Glendale, California. [1] He purchased the rights to the Kinner Sportwing, a side-by-side monoplane training aircraft and modified it as a tandem-seat trainer to compete for the Civilian Pilot Training Program build-up prior to World War II. The prototype received ATC# 733 on January 1, 1941. The Timm Aerocraft 2AS lost out to a Fairchild design. The design was sold to Aetna Aircraft, with only six examples produced. [2] [3]

The Aerocraft is a conventional landing gear equipped, strut-braced, low-winged monoplane with open cockpit tandem seating and a Kinner R-5 radial engine. The fuselage is welded steel tubing with aircraft fabric covering. The wing uses wooden spars and ribs with fabric covering. [4]

Operational history

The prototype aircraft was test flown by longtime Timm associate Frank Clarke in 1941. [5]

An Aetna 2AS won the Antique Champion award at the 1985 EAA Airshow at Oshkosh, Wisconsin. [6]

The sole surviving Timm 2AS, the fourth to be built, is preserved in an airworthy condition at the Iowa Aviation Museum and Hall of Fame located at Greenfield, Iowa. [7]

The Bach Air Yacht was a trimotor airliner produced in the United States in the 1920s. Typical of its day, it was a high-wing braced monoplane, with fixed tailwheel undercarriage. Unusual for airliners of the late 1920s, the Air Yachts were constructed almost entirely of wood with steel fittings, undercarriage, and struts. Different models were powered by varying combinations of Wright, Ryan-Siemens, Kinner, Comet, and Pratt & Whitney engines, a large engine in the nose of the aircraft, and two smaller "helpers" under the wings in nacelles supported by struts. As with so many aircraft companies of the late 1920s, the Bach Aircraft Company succumbed to the Great Depression, thus further development of the Air Yacht was abandoned after the 3-CT-9.
