## Discrepancy

AFTER GEAR RETRACTON HAD AN GEAR UNSAFE LIGHT, STAB MISCOMPARE AND HYD PRESSURE LIGHT.  NO GREEN GEAR LIGHTS WERE ILLUMINATED.  FOLLOWED CHECK LIST AND PULLED HYD CONTROL CIRCUIT BREAKER AND HEARD A NOISE UNDER FLOOR.  PUSHED BREAKER IN AND PUT GEAR DOWN NORMALLY AND STAB LIGHT WENT OUT.  FOUND THE PLUNGER BROKEN OFF R/H MLG UPLOCK SWITCH AND THEREFORE "HYD PRESS ON" COULD NOT EXTINGUISH. REMOVED AND REPLACED THE UPLOCK SWITCH. PERFORMED GEAR SWING & ADJUSTED SWITCH. GEAR FLAP & STAB OPS CHECKED GOOD. WORK DONE IAW THE MM 32-30-05.
