The Tailwheel Began To Shimmy, And The Airplane Drifted Left Of The Centerline… Analysis: During the landing as the tailwheel touched down on the runway, the tailwheel began to shimmy, and the airplane drifted left of the centerline. The left seat pilot attempted to maintain control, and the right seat pilot twice made minor inputs to maintain the centerline and “lifted the tailwheel” to alleviate the shimmy. When the tailwheel touched down a third time and the airplane’s full weight was placed on the tailwheel, the airplane veered sharply to the left. Full application of the right rudder did not correct the left turn, and the airplane ground looped.
