==Design and development==
The Glasair III is an all-composite cantilever low-wing monoplane. It is an improved variant of the earlier [[Glasair II]] with a retractable landing gear and powered by a {{convert|300|hp|kW|0|abbr=on}} [[Lycoming IO-540|Lycoming IO-540-K1H5]] engine. It has two seats side-by-side with dual controls. The aircraft can be fitted with wing tip fuel tanks.<ref name="Janes89"/><ref name="WDLA11"/><ref name="WDLA15"/> Since the purchase of Glasair II and III aircraft by Advanced Aero Components in September 2017, the Glasair II and III airframes have been substantially upgraded and are to be reproduced in all-carbon-fiber construction. The kits have been rebranded as G2 Heritage and G3 Heritage.
