Narrative:
On July 20, 2020, at 1600 central daylight time, a Rockwell S-2R Thrush Commander, N1662S, received substantial damage when it was involved in an accident near Harlan, Iowa. The commercial pilot was uninjured. The airplane was operated as a Title 14 Code of Federal Regulations Part 137 aerial application flight.
The pilot stated that during a spray pass he felt the airplane yaw abruptly left and remained in an uncontrollable left yaw for about 10-15 seconds and at times pitching uncontrollably downward. The top 2/3 of the rudder had separated but remained attached. When the top portion of the rudder completely separated, the pilot regained control of the airplane and landed without further incident.
The separated portion of the rudder was not recovered. The top rudder hinge had fractured through and had brown colored features consistent with corrosion. The remaining portion of the rudder and stabilizer was retained for metallurgical examination.
