Analysis

The plt was on the 2nd leg of a flt to ferry the home-built acft to the lancaster arpt for further testing. After takeoff, he requested clearance to stay in the area for a few minutes. ATC asked him if he had a problem & the plt responded 'no, I just want to check something out.' A few minutes later, he stated 'I'm in trouble.' The acft was seen & heard in a descending left turn at an estimated speed of over 100 mph with the eng running at a high RPM & with the landing gear retracted. While in a descending left turn, the acft struck a tree top. It then hit a utility pole, impacted the ground, burst into flames & was demolished by fire. No preimpact part failure or malfunction was found.
