LEAP-1B Completes Design Freeze

CFM has completed design freeze with its LEAP-1B engine; it remains on track for its first full engine test in mid-2014. Achieving the design freeze means that the engine configuration is set – frozen – allowing CFM to finalise detailed engine design drawings, which are expected to be released over the next six months; this makes way for the parts manufacturing stage. The LEAP-1B is set for CFM flight testing in 2012 and engine certification in 2016; it is scheduled to enter into service in 2017 on 737 aircraft.
