Thanks for the comments. I asked based on this incident:
Kathryn's Report: Swearingen SA-226AT Merlin IV, N54GP: Fatal accident occurred December 10, 2021 near Manchester-Boston Regional Airport (KMHT), New Hampshire
One running theory is that he forgot to have his auto-igniters on and his engines flamed out on his final approach in icing conditions. Seems like that oversight was fatal.
