BBA Aviation unit H+S Aviation recently announced an expansion of its CT7 series engine care management program (ECMP) and engine overhaul subcontract agreement (EOSA) with GE Aviation. Based in Portsmouth, UK, H+S Aviation provides engine service and support for a variety of turbine engines for fixed- and rotary-wing civil and military aircraft. As part of this agreement, GE will continue to manage CT7 ECMP contracts and supply OEM parts to H+S, which will perform all labor on engine shop visits.
Founded in 1946, H+S Aviation is split into five autonomous business units focused on a specific product range, plus a separate component repair facility and Rolls-Royce Model 250 training school. More than 350 employees work in 220,000 sq ft of modern workshops at two sites in Portsmouth.
“We’ve been working with GE since 1984, and since that time have processed more than 2,500 of their engines,” said Simon Benson, H+S global sales manager. Benson estimates that the company sees 150 CT7/T700 series engines per year. The engines power a variety of civil and military helicopters, including the Sikorsky S-92A and Black Hawk, AgustaWestland AW101 and Boeing Apache. The GE engine will also power the new AW189 and Bell 525 super-medium civil helicopters.
An average engine overhaul at H+S takes 60 days, Benson said. The company recently increased its capacity by adding a second CT7 test cell. In addition to the workforce at Portsmouth, H+S has supplemental representatives and technicians worldwide who can swap and run engines in the field.
Benson sees H+S as ideally located to receive engines from customers worldwide, being just a 90-minute drive from London.
Engines serviced by the company include the CT7/T700 series and GE CT58, Rolls-Royce 250 and Pratt & Whitney Canada JT15D PT6T. Annual throughput is 500 engines with approximate revenue of $100 million. Certifications and approvals held by the company include EASA and FAA Part 145 approvals, UK and international military approvals, CAA approval and ISO9001, AS9100 and ISO14001 quality and environmental certifications.
