On August 12, 2025, at about 1500 local time, a Van's RV-7A, N30SG, registered to Nevada Flyboys LLP out of Minden, Nevada, sustained substantial damage when it was involved in an accident at Ryan Field (2MT1), West Glacier, Montana. The sole pilot onboard sustained fatal injuries. The personal flight originated from Kalispell City Airport (S27), Kalispell, Montana, and was destined to 2MT1.

According to an additional remark, pilots must obtain a mandatory safety briefing before landing at the airfield. This briefing can be obtained at https://theraf.org/ryan-field/
According to the website:
"Prior to arrival, each pilot is required to review and acknowledge the current safety briefing, updated annually. If you are not yet an Airfield Guide user, you will need to create a free account. The RAF requires the electronic record that you received the briefing. It is valid only for the pilot making the request.
Ryan Field – as all backcountry – is for recreational enjoyment, not training. Please no touch and goes. Land, stretch your legs, have a picnic, and enjoy the area! If you'd like to pitch your tent or reserve a camping cabin, even better!"
To confirm that you've read the briefing, the website gives you two info boxes, one for your name and other for your aircraft's N number (registration, see figure 3).
