tubing was mounted at an angle through one ofEits, supports and had cracked where it made contact with an edge of the' support.. A temporary-repair was made and the testing was completed. 2Dur,ing the-ensuing-overhaul, new tubing was installed which was' bentfappropriately as it:
passed through its support mounting to preventaa' recurrence of the cracked line. A check of the other DG ' fuel lines found no other. similar-conditions.
Following the overhaul, the DG1was_ returned to service on.
