CAC Wackett Trainer Technical Details

CAC Wackett A3-22 on display at Moorabbin Aircraft Museum

During the research for my drawings of the CAC Wackett Trainer aircraft, I've collected a range of detailed technical information about this aircraft. On this page I have collected some of this technical information for viewing, as well as providing some links to additional websites or sources.

This page does not provide details about the history of the aircraft or the units which operated Wacketts, since that is already covered well by other websites (see the list of links lower down the page).

If you have any comments or corrections or additions, feel free to send an e-mail to derek "at" buckmasterfamily "dot" id "dot" au

Also note that this information is only provided for historical interest, it should not be used in any way for the servicing or repair of aircraft.
