Elvis will leave the building or at least firefighting temporarily as the Victorian aircrane is repaired ahead of Thursday's predicted scorcher.
Fire Services Commissioner Craig Lapsley said Elvis experienced engine trouble fighting a fire at Little River, southwest of Melbourne, on Monday.
Elvis had to head back from the fire, which burnt 350 hectares of grassland, after a problem with one of its two engines.
An additional heavy firebombing helicopter will cover for Elvis as it is repaired on Tuesday.
Elvis is expected to be back in action on Wednesday, ahead of high fire danger predicted for Thursday and Friday with temperatures expected to soar to around 40C in some parts of the state.
Victoria has four heavy helicopters including two aircranes and two heavy firebombing Sikorsky helicopters, which can drop 3200 litres of water at a time, as part of its 41-aircraft fleet.
"While there is no equivalent in size to aircranes Elvis and Gypsy Lady, we have moved one of the Sikorksys to Melbourne, to provide coverage today and tomorrow," Mr Lapsley said in a statement on Tuesday.
