CFM International has begun ground testing of the first Leap-1B engine developed to power Boeing’s new 737 Max family of narrowbody airliners. The joint venture between Snecma and GE announced today that ground tests began three days ahead of schedule on June 13 and that the 23,000- to 28,000-pound-thrust turbofan already has achieved full takeoff thrust. The engine is due to complete certification in 2016 as it prepares to enter service on the 737 Max in 2017.
