## Discrepancy

ON TAKEOFF THE NOSE GEAR DOES NOT RETRACT NORMALLY.  WITH THE GEAR HANDLE IN THE UP POSITION, THE MANUAL NOSE GEAR UPL DOES NOT SEAT PROPERLY.  A SIDE HYD PRESS CONTINUES TO PROVIDE PRESS ON THE UPSIDE.  HOWEVER, BECAUSE THE UPL SWITCH DOES NOT MAKE APPROPRIATE CONTACT THE RED UNLOCKED LIGHT STAYS ILLUMINATED.  VISUALLY INSPECTED LT & RT MAIN WW WIRING HARNESSES FOR SECURITY OF INSTALLATION OR LOOSENESS & CONNECTORS.
