Analysis

The acft had climbed to about 7,500 ft when the plt encountered an overspeeding left eng. He turned back toward Waco & feathered the left prop. While receiving emergency vectors to an arpt the right eng quit. While breaking out of the overcast the plt saw a pasture & pumped the gear down. The acft was unable to reach the pasture & collided with trees. Scoring was found on the cup of the left prop governor, which was evidence of an overspeed condition. However, further examination of the governor did not reveal any evidence that would hae caused an overspeed condition. No preimpact failure/malfunction of either eng was found.
