Hi
Most interesting discussion
Just another mechanic, but qualified PT6A and Cessna Caravan.
FWIW, my thoughts are that the ECTM module will record the exceedance, so will need to be interegated by technician - via laptop and that god awefull serial cable interface, and then a decision made.
From memory if the PRGB limit is exceeded it is a mandatory hot end inspection at minimum. maybe engine overhaul.
Having said that, the PT6 series is a very robust engine, and can take a lot of punishment.
