Analysis

During descent to avoid icing conditions, the pilot stated, 'I felt a surge effect from the engine. The oil pressure gage went to 0 and the mp (manifold pressure) went to 15 17 inches. Fuel pump use and mixture rich did nothing. We steered to a...field...after touchdown...the wheels hit a boggy area, the nose wheel strut broke...we nosed over.' An engine teardown at the factory revealed an exhaust valve from number 5 cylinder had broken off resulting in a connecting rod failure and eventual catastrophic fracture of the engine casing.
