Queen City Flying Service sold the plane to Johnson Flying Service in Missoula, MT and NC8112 was reregistered on this date. The airplane was used primarily to move Forest Service fire fighters and cargo to fight forest fires in the Montana and Idaho national forest service region 1. They utilized small remote airfields and sometime used parachutes for cargo drops. In addition, it also hauled supplies, passengers and mail to various small communities in Montana and Idaho mountainous areas. The plane was well suited for this type of flying being able to fly heavy loads into and out of rough short airfields high up in the mountains.
