A METRO II PLT TEMPORARILY LOSES CTL OF HIS ACFT WHEN HE LOSES 1 INVERTER FOR HIS FLT INSTS AFTER DEP FROM DTW; MI.

Narrative

AFTER GIVEN A CLRNC FOR TKOF FROM DTW I WAS GIVEN A HDG OF 310 DEGS AND A CLB TO 4000 FT. SHORTLY UPON ENTERING THE CLOUDS I REALIZED THAT MY ATTITUDE INDICATOR; HDG INDICATOR AND ALT INDICATOR HAD FAILED. I MOMENTARILY LOST CTL OF THE ACFT; CAUSING AN ATC DEV; THAT BEING A 180 DEG TURN AND A 500 FT LOSS IN ALT. I REGAINED CTL USING COPLT'S INSTS. I WAS ALSO QUESTIONED BY ATC AND I TOLD THEM OF MY PREDICAMENT. I KNOW THAT THE JET BEHIND ME WAS GIVEN A NEW CLRNC OR DEV BECAUSE OF ME. I ALSO KNOW THAT MY CTLR GAVE ME A NEW CLRNC TO IMMEDIATELY COMPLY WITH TO AVOID A CONFLICT. AN IMMEDIATE CLB TO 13000 FT AND A 220 DEG HDG. I HAD TO ASK FOR CONFIRMATION ON THIS BECAUSE I WAS VERY BUSY WITH THE ACFT AND TROUBLESHOOTING. I SOON DISCOVERED AN INOP INVERTER AND SWITCHED TO BACKUP. THIS CORRECTED ALL FAILURES. UPON REACHING MY DEST I WAS TOLD TO CALL DTW. THIS I DID AND I EXPLAINED IN DETAIL WHAT HAD HAPPENED. DTW DID AN EXCELLENT JOB IN CTLING THE SIT. AS FOR MYSELF; ONE THOUGHT ABOUT PREVENTING A FUTURE OCCURRENCE IS TO XCHK MY COPLT INSTS MORE FREQUENTLY.
