H+S Aviation, a BBA Aviation Engine Repair and Overhaul (ERO) group company, received EASA certification for its PT6T test cell in January, 2011. H+S Aviation is authorized by Pratt & Whitney Canada as a Distributor and Designated Overhaul Facility (DDOF) for the PT6T Twin-Pac®. The addition of EASA test cell approval means H+S Aviation is now fully equipped to perform repair and overhaul on site including engine testing.

“With the receipt of EASA certification we now have everything we need in-house for total repair and overhaul services on the PT6T,” stated BBA Aviation ERO President Hugh McElroy. “We received our DDOF authorization in early 2010 and have completed more than a dozen engine modules during the year, plus the site’s first full overhaul in December. Now with the test cell fully correlated and EASA certified we can offer complete service on site.”

The PT6T engine testing system is located in H+S Aviation’s Test Cell #5 which features a 3,000 shp hydraulic dynamometer, data acquisition system, acoustic intake and exhaust systems, instrumentation and air, fuel, water and oil systems.

“We are a global company and are growing our services to keep pace with an expanding worldwide demand for services,” continued McElroy. “With DDOF authorizations at both H+S Aviation in England and at Dallas Airmotive in the United States, we can effectively cover the globe with solutions for    Twin-Pac operators.”

Twin-Pac engines are used on Agusta/Bell Model 412 and Bell 212 helicopters and also on the Sikorsky S-58T. These helicopters are commonly used for offshore transport and heavy duty utility operations.
