Analysis

The plt reported that because of the wind condition, 15 KTS gust to 20 KTS, he used an apch speed of about 98 to 102 mph, instead of 87 mph which he normally uses. He also used full flaps. During the apch the plt sideslipped the acft to compensate for the x-wind. According to the plt, there was a 15 to 20 ft high dirtbank short of the rwy, and when he flew over it, the acft encountered a downdraft. The plt reported the acft abruptly lost 30 ft of altitude and as he tried to recover, the r main gear struck the dirtbank, separating the gear from the acft. The acft landed on the rwy and slid to a stop.
