CFM International shipped a record number of engines in the first nine months of 2017, delivering a combined 1,333 Leap and CFM56 powerplants, up from 1,326 in the same period a year earlier.
Safran, a partner in the CFM joint venture with GE Aviation, says the ramp-up on the Leap programme has continued "as planned"; it is maintaining its target of 450 deliveries this year.
In total, 110 Leap engines were shipped during the quarter ended 30 September, bringing to 257 the total handed over so far in 2017, says Safran. At this stage in 2016, 33 Leap powerplants had been delivered, of which 22 were shipped in the third quarter.
Meanwhile, the joint venture shipped 1,076 CFM56 engines in the nine-month period, of which 366 were in the third quarter. Deliveries so far in 2017 are 217 units lower than in 2016, "in line with the planned production ramp-down", says Safran.
However, increased Leap deliveries "more than offset" the decline in CFM56 volumes, the French manufacturer notes.
So far this year, CFM has received orders for 2,192 Leap engines and 424 CFM56s. The combined backlog now stands at 14,777 engines, or more than seven years of production.
Leap-series engine variants power the Airbus A320neo, Boeing 737 Max and Comac C919 aircraft families, while the CFM56 equips A320ceo and 737NG models.
