Analysis
Acft was destroyed when it struck pwr lines and the grnd during a single eng go-around. Following a left eng shut down due to severe vibrations, the plt overflew one arpt to return to his home base. En route, he elected not to go to full pwr due to a 3 min limitation he did not want to exceed. The plt overshot the rwy while manually extending the nose gear and elected to attempt a rt 270 deg turn to return to final while at 100-150' AGL. NLG did not extend due to hyd pump being on left eng and no pressure. During the turn, the plt lost control and the acft struck the wires. Investigation revealed that one of the blade pitch change links on the left prop had disconnected, allowing one blade to free float. The link pin assembly had backed out as a result of the safety screw backing out due to damaged and stripped threads and an improper length screw being installed. Props had 1/4' safety screws installed instead of 3/8'.
