Yep, I flew in one of them in 2016 from Fairbanks to Dawson City which has a gravel runway. I noticed the tubes under the leading edges of the nacelles that blow the gravel away from the inlets to prevent ingestion and damage to the engines. Also a deflector behind the nose tire to keep from kicking up gravel.
