Narrative:

After lift-off from ksrq, the landing gear would not fully retract. We got a 'right-main landing' alert on the MFDU with the blue in-transit lights remaining on. Recycling the gear, failed to clear the problem. With the gear selected down, all cockpit indications were normal. We diverted to ktpa for maintenance. A review of the aircraft history revealed a previous squawk for the same problem. On that occasion, it was determined that 1 gear door uplock was malfunctioning and was repaired accordingly. After the second occurrence, it was postulated that the uplock was failing because the landing gear assembly itself was not fully up and locked, thereby resting on the gear door instead. Handling of the situation went smoothly for us as the flight crew. The real problem may have been a misdiagnosis by the maintenance team at another company facility.

Title: R MAIN LNDG GEAR WOULD NOT FULLY RETRACT. FLT DIVERTED FOR REPAIR.

Narrative: AFTER LIFT-OFF FROM KSRQ, THE LNDG GEAR WOULD NOT FULLY RETRACT. WE GOT A 'R-MAIN LNDG' ALERT ON THE MFDU WITH THE BLUE IN-TRANSIT LIGHTS REMAINING ON. RECYCLING THE GEAR, FAILED TO CLR THE PROB. WITH THE GEAR SELECTED DOWN, ALL COCKPIT INDICATIONS WERE NORMAL. WE DIVERTED TO KTPA FOR MAINT. A REVIEW OF THE ACFT HISTORY REVEALED A PREVIOUS SQUAWK FOR THE SAME PROB. ON THAT OCCASION, IT WAS DETERMINED THAT 1 GEAR DOOR UPLOCK WAS MALFUNCTIONING AND WAS REPAIRED ACCORDINGLY. AFTER THE SECOND OCCURRENCE, IT WAS POSTULATED THAT THE UPLOCK WAS FAILING BECAUSE THE LNDG GEAR ASSEMBLY ITSELF WAS NOT FULLY UP AND LOCKED, THEREBY RESTING ON THE GEAR DOOR INSTEAD. HANDLING OF THE SIT WENT SMOOTHLY FOR US AS THE FLC. THE REAL PROB MAY HAVE BEEN A MISDIAGNOSIS BY THE MAINT TEAM AT ANOTHER COMPANY FACILITY.
