This component controls the aircraft's **flaps**—the movable surfaces on the wings that help with takeoff and landing.\n\n**Who must comply:** Owners and operators of specific Piper PA-31 models with particular serial numbers:\n*   **PA-31, PA-31-300, PA-31-325:** Serial numbers 31-2 through 31-771205\n*   **PA-31-350:** Serial numbers 31-5001 through 31-7752092\n\n**Exemption:** Aircraft already modified according to **Piper Service Letter No. 834** do not need to comply.\n\n**What you must do:** Reposition the flap solenoid following the instructions in **Piper Service Bulletin No. 567**. You must do this **immediately** (the directive uses the term \"forthwith,\" meaning without delay).\n\n**Why this matters:** Incorrect positioning of the flap solenoid could potentially affect how the flaps operate, creating a safety risk during critical flight phases like landing."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-31-60-amdt-1-flap-solenoid-repositioning","history":"/api/acts/ad-pa-31-60-amdt-1-flap-solenoid-repositioning/history","analysis":"/api/acts/ad-pa-31-60-amdt-1-flap-solenoid-repositioning/analysis","conflicts":"/api/acts/ad-pa-31-60-amdt-1-flap-solenoid-repositioning/conflicts","importantCases":"/api/acts/ad-pa-31-60-amdt-1-flap-solenoid-repositioning/important-cases","documents":"/api/acts/ad-pa-31-60-amdt-1-flap-solenoid-repositioning/documents"}}
