The Turbomeca Arrius 2R turboshaft made its first ground run on April 29 at the company’s test facility in Bordes, France. The derivative engine, which is in the 500-shp class, will power the in-development Bell 505 Jet Ranger X light single. The Arrius 2R features Fadec and a 3,000-hour time between overhaul. Certification is expected late next year.
