Subsequently the right wing impacted the beach first, then the left wing, the left landing gear collapsed, and the airplane came to a stop. The airplane sustained substantial damage to both wings. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
