## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Dassault Model Falcon 2000 airplanes. This proposed AD would require an inspection for the presence of fail-safe pins, nuts, and washers on each engine, and replacement of the fail-safe fastener assembly with a new assembly if necessary. This proposed AD results from a report of a missing pin of a fail-safe fastener. We are proposing this AD to prevent reduced structural integrity of an engine mount due to a missing pin of a fail-safe fastener, and possible separation of an engine from the airplane during flight.
