Analysis

While performing aerobatics at an airshow, the fabric on top of the upper wing started separating from the wing. The plt continued flying the acft & tried to return to the arpt. However, when flt could not be maintained with full power, due to loss of airspeed & alt, the plt parachuted from the acft. The acft crashed in an open field & burned. The plt's parachute opened just seconds before he impacted the ground. He received serious injuries during ground contact after initiating his bail-out at aprx 500 ft. the owner/builder stated that he realized that fabric of aerobatic acft normally have stiches 1 inch apart, but he built his with stiches 2 inches apart. He stated that when he built the acft, he did not plan to allow aerobatics to be done with the acft.
