## Discrepancy

AT 43,000 FT GOT TWO CAS MESSAGES DOOR CARGO OPEN AND DOOR LG OPEN CAME ON AND IT SOUND LIKE THE GEAR DOOR OPENED FOR A SECOND OR TWO AND THEN CLOSED. REMOVED & REPLACED THE # 2 LANDING GEAR AND HYDRAULICS CONTROL UNIT WITH AN "INSPECTED" UNIT IAW  AMM 32-01-01.  FUNCTIONAL CHECKS & OPS TESTS ARE GOOD AT THIS TIME.
