## Discrepancy

(CAN) AD CF61-7 CALLS FOR AN ANNUAL REPLACEMENT OF THIS TUBE, HOWEVER THIS OPERATOR HAS OBTAINED AN AMOC TO ALLOW OPERATING UNTIL FAILURE.  IT HAS BEEN FOUND THAT THIS TUBE WILL FAIL AT ANY TIME, REGARDLESS OF REPLACEMENT OR TIME IN SERVICE.  IT WILL FAIL AT THE BASE WHERE IT IS INSERTED INTO THE TANK FITTING, AND WILL MANIFEST ITSELF AS A MINOR (WEEP).  THE DANGER OF COURSE IS IF IT BREAKS OFF ENTIRELY.  THEREFORE, CONTINUED VIGILENCE IS PARAMOUNT. (TC NR 20070804001)
