Queensland based Helitak has received an FAA Supplemental Type Certificate for its FT-11K retractable aerial firefighting tank for use on the CH-47 Chinook. In development and testing for several years, the FT-11K is a retractable design, that can be fitted to any CH-47 with no modification needed to the landing gear or external structure of the aircraft.
The CH-47 tank, launched in conjunction with Alaska based Rotak Helicopter Services, began testing during 2023 in California, Idaho, and Arizona, before the receiving the STC.
