## Discrepancy

THERE ARE TWO IDENTICAL CRACKS, ONE IS ON THE LH ENGINE COWLING AND THE OTHER IS ON THE RH ENGINE COWLING. THE CRACKS GO FROM THE TOP ENGINE INSPECTION DOOR TO THE NACA INLET. THESE ARE COMMON CRACKS AND WERE FOUND ON A RECEIVING INSPECTION OF THIS AIRCRAFT. *** THIS AIRCRAFT REMAINS OUT OF SERVICE AT THE TIME OF THIS SUBMISSION FOR HEAVY MAINTENANCE, AND TO REPAIR THESE CRACKS. ***
