CFM begins LEAP-1B engine ground testing

摘要

CFM International has started ground testing of the first LEAP-1B engine at Snecma (Safran) facilities in Villaroche, France. The testing is the first step of a two-year programme that will culminate in engine certification in 2016 and entry into commercial service on the Boeing 737 MAX airplane in 2017. The LEAP-1B engine, which is the exclusive powerplant for the 737 MAX family, fired for the first time on 13 June 2014, three days ahead of the schedule set when the programme was launched in 2011. After a series of break-in runs, the engine has been operating smoothly and has reached full take-off thrust.
