Providence Health Care merged with Empire Health Services in 1994 and was re-named Inland Northwest Health Services. The respective air ambulance services of the companies were merged to form Northwest MedStar. Headquartered in Spokane, W, Northwest MedStar served eastern Washington, northern Idaho, western Montana and eastern Oregon. Delivered new in 1999, N312MS joined Oregon based Life Flight Network which bought Northwest MedStar in 2016. The helicopter was re-registered N841LF in 2018 and is current at the time of uploading.

A four fold increase in the production of cherries in Washington State between 1999 and 2017 (26.5 million 20-pound boxes) is behind a major increase in the number of helicopters under contract to area growers to fan rainwater off maturing fruit to prevent splitting between May and August. This includes a remarkable fleet of about 15 Sikorsky S-55s operated by Golden Wings Aviation's Dave Smith (in 2016) and nine S-58s operated by VI 1 LLC based at Anderson Field in Brewster, WA and the nearby Monse heliport. This S-55 (ex 54-1422) and 14 others were re-registered to Sierra Aeronautics LLC of KY in 2021.
