CFM begins LEAP-1B engine ground testing

摘要

CFM International has started ground testing of the first LEAP-IB 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-IB engine, which is the exclusive power-plant 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.
