Liberty Hall Capital Partners acquired aerospace parts supplier J&M Machine LLC. The investment will expand Liberty Hall’s relationship with Boeing Co. (NYSE: BA) and the firm’s presence in the Northwest.

Renton, Washington-based J&M distributes metal parts to the aerospace sector. The target will join Accurus’ Lacroix division, which supplies parts to Boeing aircrafts. Accurus was formed by Liberty Hall in 2013 and since has purchased Precise Machining & Manufacturing in 2013; McCann Aerospace Machining in 2014; and LaCroix in 2015.

“The strategic acquisition of J&M provides Accurus with new high-precision machining capabilities inside our Lacroix division,” says Liberty Hall partner Rowan Taylor. Financial terms of the deal were not disclosed.

New York-based Liberty Hall has been in active in buying airplane part companies. Earlier in 2016, the PE firm purchased engine parts manufacturer Bromford Industries. Liberty Hall also added seat shell maker AIM Aerospace.

In other aerospace deals, AE Industrial Partners acquired metallic parts maker AC&A; MTS Systems Corp. (Nasdaq: MTSC) agreed to buy sensor producer PCB Group Inc.; and TranDigm Group Inc. (NYSE: TDG) is buying Data Device Corp. (DDC), a maker of electronic components for aircraft.

Schulte Roth & Zabel and Pillsbury advised Liberty Hall. Meridian Capital and Tousley Brain Stephens advised J&M. Bank of America Merrill Lynch provided financing.
