Analysis
The pilot reported that, while taking off and just after rotation, the right wing dropped, and the airplane started to drift right. The right wing struck the runway, followed by the nose and the left wing. The airplane cart wheeled and came to rest in grass adjacent to the runway. The airplane sustained substantial damage to the fuselage and both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
