North State Aviation, a company headquartered in Winston-Salem that specialized in aircraft repair, has closed. North State opened in 2011 at the Smith Reynolds Airport. It received $300,000 in performance-based state incentives in exchange for hiring 308 employees within four years. At one point, it was operating six maintenance lines for United Airlines and serving numerous other clients. In 2015, it expanded to Global Transpark in Kinston, and it would have received another $250,000 in incentives had it met its goals to hire 109 and invest $900,000 in the local economy. The Kinston operation closed first, and the Winston-Salem site remained open long enough to complete work in progress. Corporate leadership cited a sudden, unexpected decline in revenue sparked by an increase in Latin American competitors. Attempts to obtain sufficient capital to forestall closure proved unsuccessful. 345 workers will be affected by the closing, and North State is working with government agencies on outplacement.
