Analysis

During the landing roll at a private airstrip, the airplane struck a sinkhole and bounced 10 to 15 feet in the air. The pilot added power to cushion the next touchdown, but the airplane drifted to the left and entered tall grass on the side of the runway; the landing gear separated and the airplane sustained substantial damage to the composite bulkhead. The airplane slid approximately 150 feet before coming to a stop on its belly. The pilot said that he did not see the sinkhole. A postaccident examination of the airplane revealed no anomalies that would have precluded normal operation.
