During final approach, the pilot performed a slip to reduce altitude but touched down in the slip attitude. The airplane bounced, veered right, departed the runway into wet grass, and collided with a hangar.

Incident Summary

A pilot reported an accident that occurred during landing. While on final approach, the airplane was too high. The pilot executed a slip maneuver to reduce altitude and maintained that attitude until a few feet above the runway, at the point of flare.

Sequence of Events

According to the pilot, the airplane continued to descend during the flare and touched down while still in the slip attitude. The airplane then bounced. In response, the pilot added power. At that point, the airplane was pointed to the right of the runway heading. The pilot was unable to maintain directional control as the airplane traveled off the runway into the wet grass.

The pilot reduced power and applied heavy braking action. Despite these efforts, the airplane continued and collided with a hangar. The pilot's report did not specify the extent of damage or any injuries. The airplane's type, registration, and other details have not been provided.
