## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Model Falcon 2000 airplanes equipped with CFE Company CFE738-1-1B turbofan engines. This proposed AD would require determining the serial number of the engines installed on the airplane, inspecting any affected engine to verify that a spherical bearing is installed on the attachment fitting of the engine mount, and corrective action if necessary. This proposed AD results from a report of a missing spherical bearing on the attachment fitting of the front engine mount on an in-service airplane, and subsequent damage and abnormal fatigue of the attachment fitting. We are proposing this AD to prevent reduced structural integrity of the engine mount, which could result in possible separation of an engine from the airplane.
