This could weaken the connection and potentially affect aircraft control.\n\n**What must be done:**\nAircraft owners must follow the instructions in **Piper Service Bulletin No 856** to inspect and address any corrosion. This must be done:\n- At the next scheduled inspection after 7 May 1987\n- Repeated every year thereafter\n\n**Who is affected:**\nAnyone who owns or operates Piper PA-32 (Cherokee Six) series aircraft listed in Piper Service Bulletin No 856."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-75-stabilator-attach-fitting-corrosion","history":"/api/acts/ad-pa-32-75-stabilator-attach-fitting-corrosion/history","analysis":"/api/acts/ad-pa-32-75-stabilator-attach-fitting-corrosion/analysis","conflicts":"/api/acts/ad-pa-32-75-stabilator-attach-fitting-corrosion/conflicts","importantCases":"/api/acts/ad-pa-32-75-stabilator-attach-fitting-corrosion/important-cases","documents":"/api/acts/ad-pa-32-75-stabilator-attach-fitting-corrosion/documents"}}
