Analysis

The acft was cleared for an NDB approach to Cadillac. The wkwas 300 ft ovcst, 1 mile vis. Shortly after cancelling IFR the acft crashed on the opposite side of the arpt from the approach end of the rwy. The pilot activated rwy lights were never turned on during the approach. It was a newly commissioned system not yet on approach plates. They were on a NOTAM. An ntap revealed that the acft was following the RNAV final approach course rather than the NDB final approach course. In addition, a lighted christmas tree farm was located adjacent to the airport. Lastly, no evidence of mechanical malfunction could be found in the wreckage.
