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

Design and development[]

Timm formed the 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]
