## Narrative

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

ON MAY 18, 2013, ACFT N902VP DEPARTED COSTA RICO PILOTED BY ^PRIVACY DATA OMITTED^ (PIC) AND ^PRIVACY DATA OMITTED^ (SIC). THE DESTINATION FOR THIS FLIGHT WAS THE BAHAMAS,  EN ROUTE THE AUTOPILOT SHUT OFF ASSOCIATED WITH AN AMBER COLLISION AVOIDANCE SYSTEM (CAS) LIGHT INDICATING  A "YAW DAMPER (YD) FAILURE". THE PILOT STATED WHILE HE WAS RUNNING THE CHECKLIST FOR THE CAS, THE SIC NOTICED THE ATTITUDE INDICATOR WAS NOT WORKING PROPERLY. THE CHECKLIST FOR THE YD SIMPLY SAYS TO PRESS THE YD BUTTON TO ENGAGE IT; BUT IT WOULD NOT RE-ENGAGE. THE PIC STATED WHENEVER HE PRESSED THE YD BUTTON HE GOT A CYAN (GREEN LIGHT) CAS THAT INDICATED THE FLIGHT GUIDANCE COMPUTER(FGC)-ATTITUDE MIS-COMPARE. THE PIC THEN REVERTED HIS ATTITUDE HEADING REFERENCE SYSTEM(AHRS)TO THE #2 AHRS SYSTEM SIDE ALLOWING YD ENGAGEMENT, AFTERWARDS THE PIC CONTACTED DISPATCH AND STATED THE PROBLEM AND REQUESTED CUSTOMS AT A DESTINATION WITHIN THE US, THE ACFT WAS DIVERTED TO KMIA WHERE THE ACFT MADE AN UNEVENTFUL LANDING, AFTER CLEARING  CUSTOMS THE ACFT WAS MOVED TO LANDMARK AVN COMPANY(AN FBO), WHERE THE FAILURE OF THE #1 AHRS WAS  POSITIVELY IDENTIFIED BY CESSNA FIELD TECHNICIANS  AND REPAIRED THE FAILURE BY REPLACING THE #1 AHRS AND ASSOCIATED COMPONENTS.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
