## Discrepancy

REMOVED TUBE ASSEMBLY TO FACILITATE OTHER MAINTENANCE.  FOUND DOUBLE FLARE TOO LARGE FOR B-NUT TO SLIDE OVER FLARE.  B-NUT WOULD THREAD ON FLARE AND TIGHTEN LEADING INSTALLER TO BELIEVE FLARE WAS TIGHT AGAINST FITTING WHEN IT WAS NOT.  THIS PART WAS INSTALLED AT THE MANUFACTURER WHEN THE AIRCRAFT WAS BUILT.
