Analysis

According to the student pilot, the airplane started to drift to the right as he approached to land, at which time he corrected with left rudder. The student pilot stated, "As the plane touched down it entered a left turn and continued for 270 degrees before coming to a stop just off the runway." A postaccident examination revealed that the right wing had sustained substantial damage as a result of impact with terrain. The pilot reported no mechanical failures or malfunctions with the airplane at the time of the accident.
