Company to focus on expanding winglet tech to other aircraft makers Sandpoint, Idaho-based airplane winglet maker Tamarack Aerospace Group Inc. has opened an installation center in Aiken, South Carolina, marking its third expansion this year. The new space, which was developed through a partnership with Aiken-based Carolina Turbine Support, is intended to improve Tamarack’s ability to meet increased demand it has seen this year, says Jacob Klinginsmith, president of the Sandpoint manufacturer. “Charter operations during the pandemic have really supported upgrades,” Klinginsmith says. “We’ve seen an increase in demand for the winglets, and we want to be able to offer other products down the road.”
