Analysis

While en route, the left eng of the C-47 lost partial pwr as a result of a cracked cylinder. The crew stated the left eng was shut down and additional pwr was applied to the right eng to compensate for the increasing rate of descent. The crew stated a short time later, the right eng started running rough and forced landing was made. During the investigation, internal malfunction could be determined in the right eng.
