STS Acquires NAAS, Will Launch New Fuel Systems Business

The U.S. line maintenance provider is the latest business to be divested by the Triumph Group.

After making two new acquisitions last year, STS Aviation Group has added a further entity in the form of Triumph Aviation Services’ NAAS Division--a provider of line maintenance with specialties in fuel systems maintenance, leak detection and bladder cell repair--on March 7.

The NAAS Division contributed around $30 million in the 2018 fiscal year to the Triumph Group. Despite the healthy financial returns, Triumph has been on a drive to divest some of its non-core businesses.

Since 2016, Triumph has offloaded more than 10 businesses, most recently selling its fabrications unit to Arlington Capital Partners in January. The company says it plans to focus on product support areas such as overhaul and repair of aircraft structures and components.

The NAAS business, headquartered in San Antonio, Texas, operates more than 20 U.S.-based locations and has two facilities in Europe, one of which is located in Shannon, Ireland. Like its acquisition, STS has a location in Shannon in the form of STS UJet, which specializes in supplying aircraft seats and cabin interior parts. 

The company is expected to be integrated into STS Aviation Group’s expanding portfolio of service offerings. Mark Smith, group president of STS Aviation Group, told Aviation Week that two NAAS line stations in San Antonio and Austin will be integrated into STS’s line maintenance unit immediately.

Over time, fuel systems repair services will be forthcoming across certain locations in the STS line network, Smith says. 

While Triumph has been streamlining its businesses, STS Aviation Group has been on an acquisition drive over the past three years. It has acquired the 17 U.S. and Bahamas-based line stations sold by Haeco Americas in 2016. It has also moved to expand its business in the form of new divisions, such as its ground support equipment repair company, launched in September 2018. 

Plans are afoot to launch a new fuel tanks business in the next few weeks, Smith says. “We will re-brand and re-launch the fuel systems segment of NAAS to form Tank Tigers, an STS Aviation Group company,” he says.
