What happened
On May 7, 2013, a Cessna 140, registration N89983, was performing a landing in Glenwood Springs, Colorado. During the landing rollout, the aircraft began to yaw to the right. In an attempt to correct the movement, the pilot overcorrected to the left and subsequently applied the right brake. This sequence caused the airplane to nose over, eventually coming to rest in an inverted position. There were no injuries resulting from the accident.
The investigation
The investigation focused on the mechanics of the landing roll and the aircraft's condition. The pilot reported that there were no mechanical malfunctions or failures present prior to the impact that would have prevented normal operation. The impact resulted in substantial damage to the rudder and the vertical stabilizer.
