Apologies, yes I did mean accessory gear box, long day.
This question has indeed thrown up more than I had anticipated. In my recent LPC I was given this failure, which was expected to be treated as severe damage, action the memory items and not attempt a restart. We did however treat it as an engine failure, which was mentioned in the debrief.
As a previous poster has suggested, should this not be treated as severe damage? If it is treated as an engine failure our company SOP's dictate an attempt at a restart, which in this instance would be futile.
Interesting thread!!
