## Discrepancy

(CNTRL NR 0501) DURING TAKEOFF, LANDING GEAR WOULD NOT COME UP (HANDLE WOULD).  WHEN GEAR HANDLE WAS PUT DONW, 3 GREEN DOWN AND LOCK AND AUTO SLAT LIGHT ON THE GEAR HANDLE WAS LOCKED (GROUND MODE).  AIRCRAFT JACKED, GEAR SWUNG NORMALLY IN HANGAR.  FOUND NOSE GEAR PROX SWITCHES WEAK.  REPAIRED PROXIMITY SWITCH AND TESTED IAW MM.  OK, EVERYTHING DONE IAW MM. (EA11200502913) (EA11200502879) (K)
