## Narrative

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

ON 3/1/18 AT APPROXIMATELY 1108 LOCAL TIME,  N121PZ DEPARTED OAKLAND COUNTY INTERNATIONAL AIRPORT (KPTK).   ON THE CLIMBOUT PILOTS NOTED BOTH HEADING INDICATORS SLOWLY ROTATING DURING A STRAIGHT OUT DEPARTURE.  THIS WAS FOLLOWED BY A "HEADING MIS-COMPARE" WARNING FOLLOWED BY "ATTITUDE FAIL" ON BOTH PRIMARY FLIGHT DISPLAYS (PFDS) AND STANDBY INDICATOR. THE PILOT STATED THAT ALTITUDE AND AIRSPEED INDICATIONS SEEMED TO BE OPERATIONAL. AN EMERGENCY WAS DECLARED BY DETROIT (DTW) AIR TRAFFIC CONTROL. THE AIRCRAFT WAS INITIALLY VECTORED TO FNT.  BASED ON WEATHER CONDITIONS, THE PILOT CHANGED THE EMERGENCY DESTINATION TO MUSKEGON AIRPORT (MKG) WHICH WAS UNDER VISUAL METEOROLOGICAL CONDITIONS.  THE AIRCRAFT LANDED WITHOUT INCIDENT. THE PILOT, WHO IS ALSO THE DESIGNATED AIRCRAFT MECHANIC, SHUT DOWN THE AIRCRAFT AND PERFORMED A COMPLETE AHRS SHUTDOWN AND RE-INITIALIZATION. AFTER REINITIALIZATION, THE AIRCRAFT WAS TAXIED TO VERIFY ATTITUDE /HEADING INDICATIONS WORKING CORRECTLY.  AFTER SUCCESSFUL VERIFICATION OF OPERATIONAL SYSTEMS, THE AIRCRAFT DEPARTED MKG AND FLEW TO DENVER INTERNATIONAL AIRPORT (KDEN) WITHOUT INCDIENT.  SEVERAL SUBSEQUENT FLIGHTS HAVE BEEN COMPLETED IN THIS AIRCRAFT SINCE THE INCIDENT, WITHOUT INCIDENT.

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.
