This Special Airworthiness Information Bulletin (SAIB) alerts you, owners and operators of all Piper
Aircraft, Inc. PA-28, PA-32, PA-34, and PA-44 models, of potential corrosion on the flap hinge
and flap ribs. This also provides our recommendation to focus on the aircraft service manual (SM) as
mitigating action.
