## Discrepancy

THE LEFT SEARCHLIGHT WILL NOT SHUT OFF.  THIS HAS BEEN A RECURRING EVENT FOR THIS PARTICULAR HELICOPTER OVER THE PAST 3 MONTHS.  THERE HAS BEEN 3 SEARCHLIGHTS REPLACED.  THE TEAR DOWN REPORTS STATE THAT A SOLID STATE RELAY HAS BEEN REPLACED TO RETURN THE LIGHT TO SERVICEABILITY EACH TIME.  THIS IS NOT THE ONLY ACFT EXPERIENCING THESE PROBLEMS.  2 OTHER ACFT WITHIN THE SAME REGION HAVE EXPERIENCED THIS SAME DISCREPANCY RECENTLY.
