The aircraft:

The Wirraway was produced by Commonwealth Aircraft Corporation from 1939 to 1946. It was a modified version of the North American Aviation NA-16-2K advanced trainer (also known by its NAA accounting code NA-33), produced under license.

A total of 755 Wirraway aircraft were delivered to the Royal Australian Air Force by CAC. The Wirraway was produced in 3 distinct versions (Wirraway Mk I, Mk II and Mk III) under 7 different production contracts (CA-1, CA-3, CA-5, CA-7, CA-8, CA-9 and CA-16).

The drawings:

This is a series of drawings providing details of the construction and dimensions of the Wirraway, as well as showing the differences between the versions. These drawings have been carefully researched from factory manuals and hundreds of measurements taken from actual aircraft. They were originally drafted at 1:48 scale.
