## Analysis

THE PILOT REPORTED THAT ON A PREVIOUS FLIGHT, HE HAD AN ENGINE PROBLEM, IN WHICH, HE WAS UNABLE TO OBTAIN MORE THAN 27 TO 28 INCHES OF MANIFOLD PRESSURE. HE HAD THE ENGINE CHECKED, NO PROBLEM WAS FOUND THAT WOULD HAVE CAUSED THE LOSS OF MANIFOLD PRESSURE, AND ON TAKEOFF, IT WOULD REACH THE RED LINE. THE TAKEOFF WAS NORMAL AND A CLIMB WAS MADE TO 10,500 FT. ABOUT 35 MI FROM LARAMIE, WY, THE MANIFOLD PRESSURE DECREASED TO 17 TO 18 INCHES. UNABLE TO MAINTAIN ALTITUDE, THE PILOT ELECTED TO LAND ALONG A PIPE LINE. DURING THE LANDING ROLL, THE AIRCRAFT HIT A DITCH, THE NOSE GEAR FAILED AND THE PLANE FLIPPED OVER. AN INVESTIGATION REVEALED THAT THE BOSSES FOR THE #6 EXHAUST VALVE ROCKER ARM HAD FAILED, THE #6 INTAKE VALVE PUSH ROD HAD BROKEN AND ITS ROD TUBE WAS KNOCKED OUT OF ALIGNMENT.
