The FAA last week issued two Airworthiness Directives (ADs) that affect several models in the Piper and Cessna GA fleets. The Cessna AD affects certain models in the 300/400 series and involves replacement and repetitive inspection of hardware securing the elevator trim push-pull rod. The Piper AD affects certain Piper PA-28 models and requires inspection of the right wing rib. Both ADs go into effect on April 26, 2016.
