An airplane engine that Dayton-area workers help produce recently hit a milestone.

GE Aviation and TUlfly, a German tourism airline, recently celebrated what GE calls a world record. The CFM56-7B airplane engine, which has powered Boeing 737-800 airplanes since 1999, logged more than 50,000 flight hours “without a single shop visit,” GE said.

GE Aviation’s Vandalia facility makes tubes, ducts and manifolds for the CFM56-7B, which received 1,500 orders last year, GE said.

TUlfly has a fleet of 60 CFM56-powered aircraft.

“The record is a remarkable achievement and we are delighted that the technical and flight operational assistance from TUlfly have made such a record possible,” Friedrich Keppler, TUlfly managing director, said in a GE statement. “Here you can see what a first-class engine, in conjunction with professional flight and maintenance operation, can achieve.”

The engines are a product of CFM International, a 50/50 joint company of Snecma and GE.
