Private equity firm Liberty Hall Capital Partners has acquired AIM Aerospace, a provider of composite ducting, substructural and interiors parts for the commercial aerospace industry, for $220m.

The deal is yet to receive customary closing conditions.

After completion of the acquisition, AIM Aerospace will support Liberty Hall’s new strategy to create a fully integrated, diversified composites supplier network through organic investments and planned acquisitions.

Liberty Hall founding partner Rowan Taylor said:"With unprecedented growth in aircraft deliveries, aircraft manufacturers are increasingly transitioning from metallic to composite materials that provide weight savings and other beneficial properties that increase fuel efficiency and durability.

"As a private equity firm focused exclusively on the aerospace and defense industry, we see significant opportunities in this segment of the industry and believe that AIM Aerospace possesses an ideal combination of capabilities, customer relationships and a proven track record of success."

"Liberty Hall provides a unique combination of relationships, experiences and resources that will allow us to grow AIM Aerospace and better serve our existing and new customers."

Established in 1988, AIM Aerospace employs more than 1,000 people at its facilities in Washington, US. The company provides composite ducting, substructural and interiors parts to Boeing, Kawasaki Heavy Industries, Spirit AeroSystems and B/E Aerospace.

BlackRock Private Equity Partners, Northwestern Mutual Capital and other institutional investors have partnered with Liberty in the AIM acquisition.

Following the acquisition, AIM’s existing management team, led by president John Feutz, will continue to remain in their positions.

Feutz said: "Liberty Hall provides a unique combination of relationships, experiences and resources that will allow us to grow AIM Aerospace and better serve our existing and new customers."

In 2013, Liberty Hall established Accurus Aerospace, a fully integrated, highly diversified aerostructures provider, and added complex metallic machined parts maker LaCroix Industries to its portfolio last year.

In 2014, the company acquired McCann Aerospace Machining that provides large, complex monolithic machined structural parts and assemblies for the aerospace sector. In 2013, it bought highly engineered machined parts and assemblies provider Precise Machining & Manufacturing.
