new artical on the C130 crash in Australia

​By law the CVR should have been turned on before every flight but for some reason it had not been turned on while operating in NSW.

Not strictly true there, it would depend on the type of operation (FAR part 91, or part 135) the flight is being operated under, however, as it is an air tanker, the CVR part of part 135 would not apply (not more than 6 passenger seats) so , in that case the part 91 limits apply.

Part 91.609 allows an aeroplane to be operated for up to 15 days with an inoperative CVR, either removed for repairs or awaiting repair, all of which is dependent on the initial failure of CVR being actually enunciated to crew as a fault.

A Learjet I worked, with same model of CVR flew around for nearly a year with a faulty CVR not recording, only picked it up on annual test using an external test box the cockpit panel didn't display a fault.
