## Discrepancy

INDICATION APPEARS TO START AT THE EDGE OF THE UNDERCUT FOR THE DOWNLOCK THREADS, AND PROGRESSES ON DOWN INSIDE THE BORE APPROXIMATELY 0.900 INCH, RUNNING ALONG THE FORGING FLASH LINE TOWARD THE MICROSWITCH MOUNTING BOSS.  SUBJECT CYLINDER HAS BEEN RETURNED TO APPH FOR INVESTIGATION.
