In the State Aircraft Unit (Victoria) 2004-2005 annual report it states
"The operation of Helitack 147 (Bell 214B) was limited by the ability of the aircraft to maintain serviceability due to mechanical failure"
"Helitack 141 (S-64F) demonstrated the ability to quickly deliver large volumes of fire suppressant in potentially threatening situations under extreme fire danger conditions. Using direct attack on high intensity fire the Air-crane was credited with several significant saves where high value assets were protected in threating situations"
