CAUSE DESCRIPTION A'iD CO1RECTIVE ACTIO.*l: (CO:lTit;UED)

The line is to be temporarily repaired by silver soldering at the next Diesel cutage, but the diesel will not be taken cut of service again just for this repair. The leak will be permanently repaired t; hen the replacement tubing is available. This leak appears to be a fatigue failure attributable to vibration and/or a possible c.etallurgical defect in the tubing. Evaluation indicates no

, new piping support required. ,
