## Discrepancy

DURING A SCHEDULED HEAVY MAINTENANCE EVENT, THE MECHANIC FOUND A SMALL CRACK ON THE LH SIDE OF THE TAILBOOM, JUST FORWARD OF THE LEADING EDGE OF THE HORIZONTAL STABILIZER. *** THIS AIRCRAFT REMAINS OUT OF SERVICE AT THIS TIME WHILE THIS CRACK IS REPAIRED PER OEM/MANUFACTURER APPROVAL. ***
