AgustaWestland is acquiring Bell Helicopter’s 25-percent interest in the AB139 twin-turbine helicopter and increasing its stake in the Bell/Agusta BA609 tiltrotor. Consolidating the ownership of the AB139 will provide “increased sales and improved customer support,” according to AgustaWestland CEO Giuseppi Orsi. Bell Helicopter and AgustaWestland remain partners on the Model 412 and the U.S. Presidential fleet of US-101s.
