## Analysis

The pilot reported that, he entered the traffic pattern for runway 16 and noted the airspeed was a little fast on the final approach leg. The airplane touched down on the runway’s grass surface and bounced resulting in it floating before touching down again. The pilot attempted to aggressively brake and increase backpressure on the control yoke. The airplane veered to the right and despite his attempts, he could not regain directional control. The airplane collided with a hangar substantially damaging both wings. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
