Santa Ana, California-based aerospace supplier Ducommun International completed its acquisition of BLR Aerospace, which specializes in aerodynamic systems on rotary and fixed-wing aircraft.

Completion of the deal comes just a month after the companies announced an agreement on March 21. Terms of the acquisition, which was made through Ducommun’s LeBarge Technologies subsidiary, were not disclosed.

Ducommun president and CEO Stephen Oswald said the acquisition “strengthens our engineered products portfolio at the company and adds as well very important aftermarket business.”

Everett, Washington-headquartered BLR, which was founded in 1992, develops systems to improve aircraft productivity, performance, and safety that include FastFin tail rotor enhancement and stability system, as well as winglet systems, propellers, and flow modifiers.

BLR president Mike Carpenter called his company’s portfolio complementary to Ducommun’s line of engineered products for the commercial aerospace and defense industries. “With Ducommun, BLR expects to accelerate its growth and expand its focus on innovative offerings to meet the needs of an evolving customer base,” Carpenter said when the deal was announced.
