CFM International delivered 303 Leap engines in the third quarter compared with the previous level of 110.
Partner Safran states that the third-quarter performance meant that its total Leap deliveries over the first nine months reached 741 – a rise of nearly 2.9 times.
Its combined output of 1,575 Leap and CFM56 engines is 18% up on last year, although the figure also indicates that CFM56 deliveries fell to 834 – a decline of 22%.
CFM56 deliveries were down by one-third, to 243, in the third quarter.
Safran says CFM is maintaining its target of delivering some 1,100 Leap powerplants during 2018.
It adds that it has secured Leap orders and commitments so far this year totalling 2,357 engines, taking the Leap backlog to 15,239.
The company puts the total in-service Leap-powered fleet at just over 500 aircraft, including 279 Airbus A320neo-family jets fitted with Leap-1As and 224 Boeing 737 Max jets with Leap-1Bs.
China’s Comac C919 test programme, it adds, which uses the Leap-1C, has completed around 120h of flight tests.
