Narrative:

MSL WX: overcast skies, snowing, approximately 1' of snow on runway, all markings obscured, braking reported poor to nil. On departure, unable to fully retract gear, continued climb and cycled gear several times with no improvement. We could see the main gear go up into the wells, but the doors would not close. Advised company and were told to proceed to mcn (our maintenance base) where retract tests could be performed. We leveled at 9000', lowered the gear fully since we felt we could get it up if necessary, also that might blow off ice accumulation, and we flew to mcn. Some factors include WX as stated above. Mcn was VFR with dry runways. Landing at mcn was normal. Maintenance deiced the gear and performed several gear actuations (normal).

Title: UNABLE TO RETRACT LNDG GEAR AFTER TKOF MSL.

Narrative: MSL WX: OVCST SKIES, SNOWING, APPROX 1' OF SNOW ON RWY, ALL MARKINGS OBSCURED, BRAKING RPTED POOR TO NIL. ON DEP, UNABLE TO FULLY RETRACT GEAR, CONTINUED CLB AND CYCLED GEAR SEVERAL TIMES WITH NO IMPROVEMENT. WE COULD SEE THE MAIN GEAR GO UP INTO THE WELLS, BUT THE DOORS WOULD NOT CLOSE. ADVISED COMPANY AND WERE TOLD TO PROCEED TO MCN (OUR MAINT BASE) WHERE RETRACT TESTS COULD BE PERFORMED. WE LEVELED AT 9000', LOWERED THE GEAR FULLY SINCE WE FELT WE COULD GET IT UP IF NECESSARY, ALSO THAT MIGHT BLOW OFF ICE ACCUMULATION, AND WE FLEW TO MCN. SOME FACTORS INCLUDE WX AS STATED ABOVE. MCN WAS VFR WITH DRY RWYS. LNDG AT MCN WAS NORMAL. MAINT DEICED THE GEAR AND PERFORMED SEVERAL GEAR ACTUATIONS (NORMAL).
