Having just read that report with some interest......the a/c I fly have various models of PT6....114, 34, 27...etc...it begs the question (and if im wrong on this..someone please correct me..as I dont want to cast any ill will to those invloved)....wouldn't this ingestion problem have been easily solved, if it was company SOP to replace intake covers after any significant period of shutdown/overnight etc...? Am I being overly simplistic?
Just a thought
