The pilot reported that after touchdown he realized that he was not going to be able to stop the airplane before the end of the runway, and aborting the landing was not an option as he did not feel that the airplane would clear the trees at the end of the runway. The pilot chose to run off the end of the runway where the airplane subsequently struck bushes and impacted terrain.
The airplane sustained substantial damage to the left wing.
The pilot reported that there were no preimpact mechanical failures and malfunctions that would have precluded normal operation.
