THE HOMEBUILT EXPERIMENTAL GLIDER EXPERIENCED AN INFLIGHT STRUCTURAL FAILURE OF BOTH WINGS WHICH SUBSEQUENTLY RESULTED IN A LOSS OF CONTROL AND IMPACT WITH THE TERRAIN. EXAMINATION REVEALED THE WINGS FAILED DUE TO OVERLOAD AT WING MIDSPAN NEAR THE SPOILERS. RECOVERY FROM LOOPS UTILIZING THE SPOILERS AS AIR BRAKES WILL CAUSE AN INCREASED BENDING MOMENT OUTBOARD OF THE SPOILERS AND REDUCE WING STRENGTH IN THE SPOILER BOX AREA. THE PLT HAD 35 HRS OF FLT TIME IN THE ACFT, AND HAD LOGGED PERFORMANCE OF LOOPS IN HIS PLT LOGBOOK. AEROBATICS ARE PROHIBITED IN THIS ACFT.
