## Discrepancy

THE AIRCRAFT LANDED UNEVENTFULLY AND WAS SHUT DOWN BY THE PILOT. AFTER SHUTDOWN THE PILOT INSTALLED THE GROUND HANDLING WHEELS AND BEGAN TO MOVE THE AIRCRAFT INTO THE HANGAR. WHILE GROUND HANDLING THE AIRCRAFT THE AFT RIGHT HAND LANDING GEAR STRUT BROKE AND COLLAPSED. VISUAL INSPECTION OF THE STRUT REVEALED A CRACK THAT STARTED AT THE WELDED BRACE ON THE UPPER STRUT AND EXTENDED ALL THE WAY AROUND THE STRUT.
