    Even More Boomeramgs coming back. (Pt.2)

    A46-54 is located in Greg’s workshop which is not situated on the airfield so when the aircraft is completed in the near future it will have its wing outer panels removed and the entire aircraft will be transported to Caboolture airfield near Brisbane Queensland for reassembly and trial flights. Progress on other aircraft in the workshop has also been excellent.

    CA-12 Boomerang A46-55 had at the time of our last visit only just been taken out of storage prior to restoration being commenced and since then progress is amazing. The fuselage which was remarkably complete internally has been stripped out of all components for a new bespoke wooden shell to be constructed.

    Regular readers will be aware that the Boomerang wooden shell is unique to each aircraft given the nature of CAC Boomerang construction and no two shells are identical. The shell for A46-55 is the first one Greg has used which is constructed from Australian sourced Hoop Pine as the previous shells were all constructed utilizing North American sourced timbers which have proven to be almost impossible to obtain recently. The Australian material has proven to be an excellent replacement and in some ways even better. The majority of the metal components have now been made and fixed to the wooden shell.

    A46-55 will now have the shell removed again to allow for the refurbishment of the internal frame and will then be fitted out with all of the hydraulic, electrical and fuel systems as they are refurbished as well as the seat, cockpit fittings, controls and instruments. The canopy is in the process of being rebuilt.

    A new North American Harvard Mk IV center section is in the process of being converted to CAC Boomerang configuration. Readers of previous articles will be aware that this Harvard item is similar to the Boomerang component and can be converted to be a near exact match, however it is a time consuming and complex task. Once this wing center section is complete it will be mated to the refurbished fuselage.

    New build outer wings will be constructed while most of the tail assembly is already in storage awaiting rebuild. The firewall and metal forward fuselage panels have also been trial fitted and the engine mount is still to be refurbished. It is expected that progress on the rebuild of A46-55 will accelerate from here on in. This aircraft is currently owned by Greg and is available for purchase by interested parties in a configuration to suit the buyer.

    CA-12 Boomerang A46-77 has also progressed for its Queensland based owner and is awaiting the modification of the Harvard MK IV center section as with A46-55 whilst a host of smaller items are also now being completed to allow for the completion of the fuselage.The fuselage shell for A46-77 has been completed for some time and temporally fitted for alignment of other parts. A Pratt & Whitney R-1830-90 Twin Wasp radial engine is held along with the 23E50 Propeller for this project.

    CA-12 Boomerang A46-92 rebuild schedule has recently been accelerated for its internationally based owner. The wooden shell has had fabric covering applied and is temporarily in place with activity continuing on it to attach most of the metal work progressing at a pace. Again a Harvard Mk IV center section has been obtained and will be converted for this airframe. The forward cockpit frame has also been repaired and is awaiting refitting in place of the current one fitted temporarily.

    We will report again as work progresses on this very impressive workshop dedicated to Australia’s own indigenous fighter, the CAC Boomerang. The highlight of this year should definitely be the first flight of Greg’s own “ Boomer” A46-54 .

    Warbirds Online extends our thanks Greg Batts and the team at Combat Aircraft Constructions for allowing us access to this unique facility.
