Analysis

The plt obtained a wx briefing and was advised of scattered thunderstorm activity along his route of flt. The plt then filed an IFR flt plan from wiley post airport, Oklahoma city, OK, to houston intercontinental airport, TX. The plt and his wife took off at 1235. The acft climbed to its assigned alt of 11,000 ft MSL and proceeded routinely until 1310 when ARTCC told the plt to contact fort worth center. The plt acknwledged but never contacted the center. Radar contact was lost at 1319. Witnesses reported hearing a loud explosion and observing wreckage falling from the sky. Witness observations and wx radar confirm there was a thunderstorm just north of the crash site through which the acft flew. Wreckage examination revealed the horizontal stabilizers failed negatively and separated from the acft. Both wings then failed negatively and separated from the acft.
