## Discrepancy

ON DESCENT, DUE TO RUNWAY CHANGE, EXTENDED LG AT 235 KTS, ONCE ON DESCENT RETRACTED GEAR AT 220 KTS, BOTH MAIN GEAR INDICATED UNSAFE UP ON RETRACT.  EXTENDED GEAR & GOT 3 GREEN.  PERFORMED A TEST OF PSEU SENSORS, ALL INDICATED OKAY.  THERE WERE NO CURRENT FAULTS LISTED IN THE PSEU.  VISUALLY INSPECTED ALL UP & DOWNLOCK & UPLOCK TARGETS & SENSORS, NOTHING ABNORMAL FOUND.  CONSULTED WITH MOCC & WAS INFORMED THIS IS AN SDR. THE ONLY MM ADJUSTMENT TEST PROCEDURE REQUIRES A GEAR SWING.  STILL RESEARCHING A POSSIBLE MM IAW MX.  COMPLIED WITH IAW MM CH 32-61-15-5 FOR PROX SENSORS.
