## Discrepancy

(CAN) CREW REPORTED THAT THE GEAR WOULD NOT RETRACT AFTER TAKEOFF. DECISION MADE TO DIVERT FOR MX WITH THE GEAR DOWN.  MX JACKED THE ACFT AND ATTEMPTED TO RETRACT THE GEAR, FOUND THE LT MLG WEIGHT ON WHEEL SWITCHES WERE UNSERVICEABLE, BOTH REPLACED AND ACFT RETURNED TO SERVICE. PN D22878000-1 AND D22883000-1.
