CFM56-5B/P To Begin Flight Tests; Engine Set For Certification On A319 In June

February 6, 1996

CFM International's improved performance CFM56-5B/P engine will began a 50-hour flight test program on an Airbus Industrie A320 testbed later this month, paving the way for aircraft/engine certification in June.

The CFM56-5B/P has successfully completed more than 750 engine cycles, including performance and engine endurance testing. The engine has verified that it meets all performance commitments with margin and improves specific fuel consumption by as much as 2.5 percent, depending on the aircraft application, compared to the current CFM56-5B configuration.

The CFM56-5B/P will enter revenue service on a Swissair A319 in June 1996, three months earlier than projected. All A319 aircraft will be delivered with the CFM56-5B/P configuration.

In April, the CFM56-5B3/P will begin a 65-hour flight test program on the new 89-tonne Airbus A321-200. Aircraft certification and entry into service are scheduled for the second quarter of 1997.

The CFM56-5B/P core and low pressure turbine serve as the basis for future CFM56 engine programs, including the CFM56-7 engine for the next-generation Boeing 737-600/-700/-800. CFM56-5B/P engine improvements include a new high pressure compressor and more efficient, redesigned high and low pressure turbines.

CFM International is a 50/50 joint company of Snecma (Safran Group) of France and General Electric of the United States.
