Indonesian airline Lion Group has selected CFM International’s CFM56-5B engine to power 60 Airbus A320ceo aircraft in a deal worth more than $1.2 billion. The airline has been a CFM customer since 2000 and recently took delivery of its 100th CFM56-7B-powered Boeing 737 aircraft.

Rusdi Kirana, Lion Group founder and president, said: “Our selection of the CFM56-5B engine for the A320ceo aircraft was an obvious choice for us. Although we are introducing a whole new engine type, it is coming from the same company that has been with us from the very beginning.”

All of Lion Group’s new engines will be the CFM56-5B PIP (Performance Improvement Package) configuration, which provides a 0.5% improvement in fuel burn. It has the same noise signature as the current production engine and meets current standards.
