Summary
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires an inspection of the elevator spar for cracks and, if any crack is found, either replacement with a serviceable elevator spar that is found free of cracks or repair/ modification with an FAA-approved method. This AD also requires reporting to the FAA the results of the inspection. This AD was prompted by reports of a total of nine elevator spar cracks across seven of the affected airplanes, including a crack of 2.35 inches just below the outboard hinge of the right-hand elevator. We are issuing this AD to prevent structural failure of the elevator spar due to such cracking, which could result in separation of the elevator from the airplane with consequent loss of control.
