Omaha - Grand Island

The twin engine aircraft crashed and burned 4 miles north of the airport while on an instrument approach. The pilot had transmitted that he had an engine problem. The #5 cylinder was found detached from the left engine but the left propeller was not feathered. An engine teardown revealed evidence to indicate the #5 cylinder attachments were not properly torqued. No preimpact failure could be found with the right engine. The right propeller was found in feathered position. The pilot, sole on board, was killed.
