## Discrepancy

AIR RETURN, UPON CLIMB AND RETRACTION OF THE GEAR THE PILOTS REPORTED THAT THE LT MAIN GEAR WOULD NOT RETRACT AND A GRINDING NOISE WAS HEARD. THE GEAR THEN EXTENDED NORMALLY. MX WAS DISPATCHED AND FOUND BOTH LT UPLOCK SENSORS LOOSE. MX TIGHTENED AND ADJUSTED SWITCHES IAW MM 32-60. OPS CHECKS WERE GOOD.
