Analysis

The acft impacted in a swampy area in a fast dive which separated about 6 ft of the left wing. The acft was being vectored on radar when it suddenly began to steer erratically and go off the radar scope. The plt had radioed that he 'must have gone over some electronic interference that tumbled my gyros and screwed up my compass'. His instruments were not electronic but vacuum operated from the engine driven pump. Disassembly of the pump after the accident showed no evidence of preimpact failure. The forecast for the area was 2000 to 3000 broken with overcast occasionally below 1000 ft with rain showers and fog. The lakeland, FL 1650 wx observation reported rain showers north. Lakeland is 10 mi south of the crash site.
