Narrative:
During en route cruise aircraft encountered an electrical failure, along with erratic gyroscope indications. Partial loss of communications was experienced along with unreliable navigation indications. The flight was vectored for a visual approach into boston logan international airport and a landing was made safely without incident. As PIC I believe the problem arose due to a vast amount of moisture penetrating electrical and gyroscope system. It was discovered during a visual scan of aircraft instrumentation and aircraft system. Maintenance department made all necessary repairs.

Title: SMT PLT, WHILE IMC, HAS PARTIAL ELECTRICAL FAILURE. AFFECTED WERE FLT INSTS, COMS, AND NAV. TRACON GIVES VECTORS TO ARPT, AND UNEVENTFUL LNDG TAKES PLACE.
Narrative: DURING ENRTE CRUISE ACFT ENCOUNTERED AN ELECTRICAL FAILURE, ALONG WITH ERRATIC GYROSCOPE INDICATIONS. PARTIAL LOSS OF COMS WAS EXPERIENCED ALONG WITH UNRELIABLE NAV INDICATIONS. THE FLT WAS VECTORED FOR A VISUAL APCH INTO BOSTON LOGAN INTL ARPT AND A LNDG WAS MADE SAFELY WITHOUT INCIDENT. AS PIC I BELIEVE THE PROB AROSE DUE TO A VAST AMOUNT OF MOISTURE PENETRATING ELECTRICAL AND GYROSCOPE SYS. IT WAS DISCOVERED DURING A VISUAL SCAN OF ACFT INSTRUMENTATION AND ACFT SYS. MAINT DEPT MADE ALL NECESSARY REPAIRS.
