Maybe - but then it should have been briefed. Not just continue the flight doing a very wide (> 10min) pattern while the engine fire burns through the wing & flight controls.
Being rated on the CV340 they should have been aware that an engine fire on such a radial engine quickly affects the structural integrity of the aircraft.
