## Discrepancy

THE NOSE LANDING GEAR FAILED TO LOCK IN THE UP POSITION.  THE NOSE GEAR WOULD RETRACT AND EXTINGUISH THE HYDRAULIC PRESSURE LIGHT, BUT WOULD THEN FALL BACK OUT OF THE WHEEL WELL.  FOUND SHIMMY DAMPENER INTERFERING WITH THE NOSE GEAR UPLOCK SWITCH WIRE BUNDLE.  THE WIRES WERE NOT SECURED TIGHT ENOUGH TO THE ANCHORS.  REPAIRED THE WIRE BUNDLE AND ENSURED THAT THE WIRES WERE SECURED TO THE ANCHORS.
