Probable cause

The failure of the master rod bearing, which resulted in a loss of engine power.

NTSB narrative

The pilots stated that they were flying in the traffic pattern when the airplane's engine started losing power. They were unable to reach the runway and landed short of the prepared surface. A postaccident examination of the airplane revealed that the main landing gear had punctured both wings, damaging the spars, and two of the engine mounts had pulled loose from the firewall. Metal material was found in the outer casing of the oil filter. According to one of the airplane’s owners, the engine was later disassembled for salvage, and the master rod bearing was found to have failed.
