THE ACFT CAREENED OFF THE HARD SURFACED RWY INTO ROUGH AND UNEVEN TERRAIN WHICH TORE A WING FROM ITS ATTACH POINT. POST ACCIDENT EXAM OF THE ACFT AND ITS RECORDS SHOWED THAT IT HAD NOT BEEN PROPERLY INSPECTED AND WAS NOT AIRWORTHY FOR THIS FLIGHT. THE ENGINE FAILED IN WHAT APPEARED TO BE A FAILURE INDICATIVE OF A CONNECTING ROD, ROD END OR ROD BOLT FAILURE WITH A RESULTANT HOLE IN THE ENGINE CASE.
