Converted to a T300 in July 1980 by replacing the short-lived Continental/Rolls-Royce Tiara 6-320 engine with a Lycoming O-540. Crashed at Donnellys Crossing on November 16, 1983. Bob Kerr photo

PL-12T-320 was powered by a Continental Tiara 6-320 engine, which was more powerful than the standard Continental O-520. The Tiara engine was not a success and went out of production. Transavia got the extra power it sought by switching to the Lycoming O-540 for the T-300 that appeared in 1979. Bob Kerr photo

Aussie oddbal at the Museo del Aire.

The PL-12 was designed as a crop-duster and agricultural sesquiplane (a common variation on the biplane where one wing has less than half the surface area of the other). Other versions can be used as cargo, ambulance or aerial survey aircraft, and carry one passenger in the top deck and four in the lower deck. This example was ferried to Spain in 1977 and is now on display at the super Museo del Aire.
