Lycoming Engines Announces Certification and Implementation of Roller Tappet Technology

April 12, 2005

Lakeland, FL - April 12, 2005 - Lycoming Engines announced today the certification and implementation of its new valve-train roller tappet technology. Lycoming began proving these designs at last year's Reno Air Races and completed the FAA certification process in February. Lycoming, a leader in general aviation piston engines, began developing hydraulic-tappet technology in the late 1990s in an effort to increase horsepower and reduce camshaft friction.

Last September, Lycoming selected Delphi as its key production partner for roller tappets in general aviation. Delphi is a recognized leader in roller hydraulic valve lifters for automobiles.

"Implementation of roller tappets is the next step in a phased program of design enhancements to bring technology improvements that provide greater value to the customer with increased reliability and performance" stated Ian Walsh, vice president and general manger of Lycoming Engines.

Lycoming plans to make roller tappets available in the after-market beginning June 1, 2005.
