GREENWICH, CONN. – Greenbriar Equity Group, L.P. has announced that funds managed by Greenbriar have acquired West Star Aviation, a provider of maintenance, repair, and overhaul (“MRO”) services for business aviation aircraft from The Sterling Group, which purchased West Star in 2022 from Norwest Equity Partners. Financial terms of the private transaction were not disclosed.
West Star operates a full-service facility at the Perryville Regional Airport and was one of four businesses, along with the Perry County Joint Justice Center, featured in last month’s 2025 Republic-Monitor’s Progress Edition.
West Star has additional facilities in East Alton, Ill., Grand Junction, Colo., Chattanooga, Tenn., Millville, NJ, and Statesville, NC, as well as multiple satellite locations.
