Aircraft Accident/Incident Report
Breaux Bridge, Louisiana 70517
Friday, October 14, 2011 15:45 CDT
NTSB Narrative Summary Released at Completion of Accident
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.
NTSB Probable Cause Narrative
The pilot's failure to maintain control of the airplane after striking an unseen sinkhole during landing.
