Wipaire is pleased to announce you can now get your Single Engine Seaplane (SES) Rating in Wyoming.
Through the efforts of J.T. Grainger, Seaplane Pilots Association Wyoming Field Director, and Steve Guetter, President of the Minnesota Seaplane Pilots Association, SES ratings can now be achieved on Lake De Smet, Wyoming.
“Representatives from the Seaplane Pilots Association (SPA) met with the Johnson County Lake De Smet operating board to discuss pre-flight and post-flight inspections for Aquatic Invasive Species (AIS). Specifically, Steve Guetter, President of the Minnesota Seaplane Pilots Association and General Manager of Advanced Flight Training & Leasing, who shared successful techniques used in Minnesota to prevent seaplanes from transporting invasive species. Steve’s in person visit from Minnesota and first hand accurate information was crucial in getting approval to continue to operate on Lake De Smet,” said J.T. Grainger, Seaplane Pilots Association Wyoming Field Director, and owner of Sheridan Pilots 307 Flight School, “Local aircraft now have indefinite permission to access the lake and non-local aircraft can obtain access through the point of contact listed in SPA’s mobile app. We hope this will lead to expanded state-wide access.”
What does the SPA recommend to prevent the transfer of invasive species?
- Use the DNR website or the SPA mobile app to identify bodies of infected water prior to flight
- Thoroughly inspect float surfaces prior to departing a body of water
- Wipe down float surfaces when aircraft have remained in water overnight
- Pump out water from float compartments prior to departing a body of water
- After departure, visually examine water rudders and landing gear for weeds
- Cycle rudders/landing gear over unpopulated land areas prior to landing in other bodies of water
