## Discrepancy

(CAN) DURING A ROUTINE POST-FLIGHT INSPECTION BY MAINTENANCE PERSONNEL, THE LOWER FRAME ASSY WAS FOUND CRACKED AT THE UPPER L/H AFT ATTACHMENT POINT. THE BROKEN AREA DID NOT HAVE ANY EVIDENCE OF PRE-EXISTING CRACKS, AND APPEARED TO BE A CLEAN BREAK. THERE WAS NO REPORTED EXCESSIVE VIBRATIONS OR ANOMALIES BY THE PILOT WHO HAD FLOWN THE AIRCRAFT LAST.
