What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
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.
