A TECHNICIAN RPTS CONDUIT CHAFFING AND EXPOSED ELECTRICAL WIRES ON B737-300 NOSE GEAR AIR-GND SENSOR WIRING.

Narrative

ON WALKAROUND; FOUND SEVERAL WIRES FROM NOSE GEAR AIR-GND SENSOR CONDUIT BROKEN. THEY WERE STICKING OUT ABOUT 90 DEGS FROM CONDUIT. I HAVE FOUND THESE BROKEN WIRES ON A FEW ACFT. BECAUSE OF THEIR LOCATION AND THE RETRACTION OF THE NOSE GEAR; IT SEEMS TO BE HAPPENING MORE. THE TECHNICIAN WHO REPAIRED IT WRAPPED IT PER THE MAINT MANUAL AND CREATED A DEFERRAL. I MADE THE ORIGINAL WRITE-UP ON THE ACFT. AFTER MY 3 DAYS OFF (WKEND); I WAS BROUGHT INTO THE OFFICE AND DISCHARGED FOR MAKING EXCESSIVE WRITE-UPS. DURING THE COURSE OF 6-8 MONTHS; I HAVE WRITTEN UP ABOUT 6-9 CONDUITS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED AN FAA SAFETY INSPECTOR CALLED HIS ATTN TO A WORN ELECTRICAL CONDUIT WITH EXPOSED WIRING ON A B737-300 NOSE GEAR GND SAFETY CIRCUIT.
