Today Germany’s TUIfly and CFM celebrated a new first-run time-on-wing world record set by a CFM56-7B engine powering one of the airline’s Boeing 737-800s. This engine logged more than 50,000 hours without a shop visit. That’s equivalent to 2,083 days or nearly six years!
“This record is a remarkable achievement and we are delighted that the technical and flight operational assistance from TUIfly have made such a record possible.Here you can see what a first class engine, in conjunction with professional flight and maintenance operation, can achieve, “said Friedrich Keppler, Managing Director TUIfly.
This is a remarkable performance.
Six years would be if the engine ran 24 hours a day. But that engine more than likely averaged less than 12 hours a day over its lifetime. That means it probably stayed on wing more than 12 years!
Charter/ leisure operators make longer flights (south) then the typical cityairs and feeder flights. So cycles would be relatively low compared to many other 737 o the same age.
