Analysis

The acft crashed during a go-around attempt at Theodore River located 35 miles southwest of anchorage, AK. According to the plt, after landing on a gravel oil pad he realized that the acft would not stop before going over the edge into a swamp. He applied power but the main gear struck a stump and the acft settled into the mud. The plt stated that he knew the acft brakes may not have been able to stop the acft due to their worn condition.
