Thanks for the compliments on the CHC ECL.
I can recall one real engine fire on a 332L a number of years ago in Aberdeen (it wasn't me). Fire warning just after TDP on a maintenance check flight post engine maintenance. Casual glance in the mirror, which showed significant flames coming out of the starboard engine cowling. Fire drill followed by rapid return to land. The airframe had significant damage below the engine bay including melted aluminium. I think the cause was a loose fuel pipe union on the FCU.
