Analysis

An experimental designed prototype acft was being flown on its first flt. The acft took off and flew in ground effect beyond the arpt boundary. At full pwr, the acft could not maintain altitude and descended uncontrolled to an impact with the terrain. The nose gear collapsed and the acft nosed over. Original design of the acft was 950 lbs gw with a 60 HP eng. As this prototype was equipped its climb rate was a minus 75 ft/min. In a post flt test the involved eng produced less than 40 HP. The acc plt stepped into the program 10 days before the acc after the original contracted test plt quit. The test was flown in spite of some of the technicians skepticism of success.
