Precautionary field landing following elevator tab vibration, 2 nm southwest of Mablethorpe, Lincolnshire, 8 May 2016.
Shortly after the aircraft entered cruising flight the trim servo actuator arm of the left elevator anti-balance trim tab fractured, resulting in severe vibration of the aircraft’s pitch control circuit. The pilot carried out a successful precautionary landing in a field. Examination of the aircraft showed that excessive up elevator deflection had caused bending loads to be applied to the trim servo actuator arm, leading to its structural failure.
