CTLR RESPONDS TO ALT ALERT AND GETS ACFT BACK TO PROPER ALT.

Narrative

ON JUL/TUE/94; FILED IFR FROM 4B8 TO CQX AFTER OBTAINING WX BRIEFING (WX NOT AS GOOD AS FORECAST). CTLR VECTORED ME FOR VFR APCH TO CQX; BUT WX WAS IMC. ADF BECAME INOP BUT CAME BACK ON AND AN NDB-A APCH WAS INITIATED. DECLARED A 'MISSED APCH' WHEN ARPT WAS NOT VISIBLE AT MINIMUM DSCNT ALT AND ASKED FOR THE ALTERNATE (HYA). WAS GIVEN 3000 FT AND VECTORS FOR LOC RWY 24 (GS WAS OTS). THEN GIVEN DSCNT TO 1700 FT UNTIL ESTABLISHED ON LOC. WHILE MANEUVERING TO CAPTURE LOC; MUCH TFC WAS BEING HANDLED AND SOME INSTRUCTIONS WERE CONFUSING BECAUSE I HAD TO ASK SEVERAL TIMES IF INSTRUCTIONS WERE FOR 'MM.' ALSO; WAS ASKED 'ON APCH' TO TUNE IN ATIS. WHILE ALL THIS WAS TRANSPIRING; MY VERT COMPASS STARTED SPINNING AND I WAS UNABLE TO RESET MY DIRECTIONAL GYROSCOPE. THE TURN AND BANK STOPPED INDICATING AND MY ELECTRIC AND MANUAL TRIM WAS BINDING. WITH ALL THIS CONFUSION; I OBVIOUSLY LEFT MY MINIMUM ALT. THE CTLR ADVISED ME OF AN 'ALT ALERT' AND ORDERED ME TO 3000 FT AND TURNED ME OVER TO ANOTHER CTLR WHO GAVE ME VECTORS FOR ANOTHER APCH. APCH WAS COMPLETED TO MINIMUMS IN SPITE OF CONTINUING PROBS. ACFT WAS TAXIED TO A REPAIR FACILITY FOR SVC WHERE AN FAA INSPECTOR QUESTIONED ME EXTENSIVELY AND INDICATED HE WOULD NOT FILE A VIOLATION. OBVIOUSLY; I ALLOWED MY DISTR WITH THE INST MALFUNCTIONS AND CONFUSING CTLR INSTRUCTIONS TO BREAK THE CARDINAL ALT RULE.
