Analysis

The acdt occurred on the arpt when the plt decided to abort the flt shortly after takeoff. The plt said that after takeoff the acft did not seem to accelerate properly so he decided to land. The takeoff had been made on a 5300 ft long rwy which has a 600 ft overrun and a 2545 ft section of unusable rwy beyond the overrun. The plt said the acft drifted to the rt after takeoff and the landing was made in the grass area beside the unusable section of the rwy. After landing the acft crossed an abandoned rwy from which the asphalt had been removed. Upon crossing the abandoned rwy the acft struck a lip and the lt canard broke off. The density alt at the time of the acdt was about 5900 ft. the plt said the flight manual instructions for high alt operations in this acft are sketchy.
