N48JP has since been reassigned. It is now registered to a different aircraft (DASSAULT AVIATION FALCON 7X), which was not involved in this event.
Aircraft involved
Probable cause & findings
THE FAILURE OF THE PROPELLER DUE TO IMPROPER INSTALLATION.
Factual narrative
FOLLOWING A SERIES OF AEROBATIC MANEUVERS TO TEST THE EFFECTIVENESS OF NEW TYPE OF COMPOSITE PROPELLER THE AIRPLANE EXPERIENCED A CATASTROPHIC FAILURE OF THE PROPELLER. THE PROPELLER WAS ISSUED WITH A KIT THAT INCLUDED THE MOUNTING BOLTS. THE BOLTS PROVIDED WERE TOO LONG AND BOTTOMED OUT RESULTING IN NO TORQUE BEING APPLIED TO THE PROPELLER. THE PROPELLER WOBBLED, AND THE PROPELLER LAMINATIONS SEPARATED. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
