## Discrepancy

(AUS) ROTOR CONTROL PUSH/PULL TUBE P/N A121-7 WORN.  INVESTIGATION FOUND THAT THE FUEL TANK RETAINING STRAP P/N A713-1 HAD NOT BEEN FITTED DURING AIRCRAFT REBUILD ALLOWING THE TANK TO MOVE AND RUB ON THE CONTROL RODS.  AN EFFORT HAD BEEN MADE TO HIDE THE DAMAGE BY USING HEAT SHRINK ON THE CONTROL TUBE AND BY FILING AWAY THE FUEL TANK.
