## Discrepancy

DURING AN INSPECTION FOUND A CRACK APPROXIMATELY SEVEN INCHES LONG ON THE TAILBOOM JUNCTION RING FRAME. THIS CRACK IS LOCATED ON THE FWD SIDE OF THE JUNCTION RING FRAME & RUNS ALONG THE RADIUS OF THE RING FRAME WEB & THE FWD FLANGE.  ACFT WAS IMMEDIATELY GROUNDED FOR TAILBOOM CHANGE.  OTHER ACFT OF SAME MODEL IMMEDIATELY INSPECTED & NO OTHER CRACKS FOUND.
