Analysis

While the cruise flight at 9500 feet the engine seized. A forced landing was made to a divided highway. Traffic forced a landing in the median where the wing hit a sign & veered the a/c into a ditch. The engine had 121 hours since overhaul. Examination of the engine revealed that the rear crankcase thru bolts were finger tight. The rear main bearing had spun, the number 1 rod cap separated, and the crankshaft had fractured through the counterweight cheek.
