If left unchecked, this cracking could lead to structural failure of the elevator (the control surface that makes the plane climb or dive), potentially causing loss of control.\n\n**What must be done:** Operators must follow the technical inspection procedures outlined in FAA Airworthiness Directive 2006-23-05.
