ABC, ABC, ABC!! You will send your turbine back anyways!! ABC's are great all around extinguishers.
Even if you don't have a CO2, if you have a fire, use an ABC! You will save your jet for the price of a turbine cleaning.
And regarding auto restart, Gasper clearly writes about the potential dangers of an auto restart! And if you know you are going down, procedure number 1 is shut down the engine. Sorry about the loss of the jet.
