Analysis

The acft crashed while on a flt in an area where thunderstorm warnings were in effect. There were no known witnesses to the actual crash, but 2 or 3 local residents heard an acft eng at about the estimated time of the accident. One resident about 1/4 mi from the crash site stated that he heard the eng aprx 5 min after a severe thunderstorm began. He stated that about 2 inches of rain fell in 20 min, visibility was restricted & there was 'very hi winds.' A local radio station at Haskell, TX recorded winds of 54 mph during the thunderstorm. An investigation revealed that the acft's right wing & both horizontal stabilators had separated in flt, then the acft crashed in a 70 to 80 deg nose down, inverted, left wing low attitude while at a hi rate of speed. The wing & stabilator failures were indicative of overload separation. One of the 5 occupants in the 4 place acft was a baby.
