## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THE REPORTING INSPECTOR INTERVIEWED THE PILOT ON 11/30/07. THE PILOT STATED THAT THERE WAS NOTICEABLE VIBRATION IN THE NOSEWHEEL AFTER THE FIRST TOUCHDOWN. THE PILOT ADDED THAT HE ATTEMPTED TO REDUCE THE VIBRATION ON THE NOSEWHEEL BY PULLING AFT ON THE YOKE. WITNESS STATEMENTS DESCRIBE THAT THE AIRCRAFT INITIALLY TOUCHED DOWN NOSEWHEEL FIRST, BOUNCED AND BECAME AIRBORNE AGAIN. THE PALOMAR ATCT REPORT (FAA FORM 8020-9), THE PILOT'S WRITTEN STATEMENT AND SEVERAL WITNESS STATEMENTS CONSISTENTLY DESCRIBE SEVERAL SUBSEQUENT TOUCHDOWN "BOUNCES" THAT ARE CHARACTERISTIC OF PILOT INDUCED OSCILLATIONS (PIO). AFTER APPROXIMATELY THE SIXTH BOUNCE, THE NOSE LANDING GEAR COLLAPSED AND THE NOSEWHEEL ASSEMBLY ASSEMBLY SEPARATED NEAR THE LOWER END OF THE OLEO STRUT. A POST ACCIDENT VISUAL INSPECTION OF THE AIRCRAFT REVEALED THAT THE NOSEWHEEL TRUNNION ASSEMBLY EXHIBITED SIGNS OF DUCTILE OVERLOAD AND STRESS CRACKING. THE AIRCRAFT CAME TO REST IN A NOSE LOW ATTITUDE. BOTH LEFT AND RIGHT ENGINE'S PROPELLER BLADES WERE BENT AFT NEAR THE BLADE TIPS. THE FUSELAGE SKIN DISPLAYS SIGNS OF DEFORMATION AND WRINKLING AFT OF THE CABIN AREA.
