So……what do you do now (In Australia)?
I'm still going to contact the OEM and get a definitive answer to the new setting. They cannot alter any data without approval.
If they don't have approval I guess it is a moot point.
Problem arises in that I can't alter the setting unless I have approval on my CofA for the component overhaul, discussions with CASA would have to take place.
Further thoughts, volt regulator is set IAW Aircraft maintenance manual same as fuel pressures etc, so may be able to alter IAW aircraft data rather than the equipment data.
