Private investment firm Norwest Equity Partners (NEP) made a significant investment in West Star Aviation, a provider of MRO support services to the business aviation industry. Terms of the transaction were not disclosed.

Antares Capital, Ally Corporate Finance and Norwest Mezzanine Partners provided financing to support the investment. Harris Williams advised West Star on the transaction. Skadden, Arps, Slate, Meagher & Flom provided legal services for NEP.

Tim DeVries, NEP managing general partner, said, “West Star’s solid business model and industry-leading management team have helped to establish extremely high barriers to entry within the business aviation market. There have been no new entrants into the market at the scale and capability of West Star in the last decade that didn’t happen through consolidation or acquisition. West Star has done a great job to earn a global reputation as a highly-valued, ‘go-to’ MRO services provider, and we’re going to work hard to leverage their existing growth momentum along with our combined NEP capital and resources to further build and grow the company.”
