## Discrepancy

Mach Trim "fail" light illumimnates intermitently. Corrective action: Defferred Mach Trim system per MEL 22-5, CI#M005089 per MX CNTL Mic. Removed and replaces Mach Trim Coupler IAW MM 22-21-31, operational check normal. This clears MEL CI#M005089. See 005 Log pages 92956 and 92957. This report filed closed.
