Thomas Cook Group has chosen CFM56-5B engines to power 12 Airbus A321s scheduled for delivery starting in 2014.
The company firmed the order today after signing a memorandum of understanding with Airbus last month.
CFM states the engines powering Thomas Cook's A321s will incorporate a performance improvement package to reduce engine fuel consumption 0.5% and lower maintenance costs by 1%. Currently the performance improvement package is undergoing flight testing at Airbus, and is scheduled for certification during the second quarter.
Most of the engines powering the A320s in Thomas Cook's fleet are supplied by CFM, with the exception of two A320s at Thomas Cook Belgium and four at Thomas Cook UK powered by IAE V2500s, according to Flightglobal's ACAS fleet database.
