Analysis

The ends of the outer string and the inner reinforcing wire of the engine air intake duct were not properly positioned under the duct clamp during installation. As a result, they unwound during engine operation and moved out of their normal position on and in the duct respectively. This allowed the wall of the duct to lose its rigidity and collapse which resulted in a loss of engine intake air and subsequent power failure. The pilot attempted to return to the airport with only 100 feet of altitude. The acft stalled during the turn with insufficient alt to recover before impact occurred.
