Previously, they had to install a warning placard (a visible sticker or plate) in the cockpit warning pilots against \"uncoordinated manoeuvres\" (flying turns or movements without properly balancing the aircraft with rudder and aileron). That requirement is now gone.\n\n**Who it affects:** Owners and operators of Piper PA-30 and PA-39 Twin Comanche aeroplanes.\n\n**Why it matters:** It removes a compliance burden. If you hadn't installed the placard yet, you don't need to bother. If you already installed it, you don't need to remove it, but it's no longer legally required."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-30-21-amdt-1-uncoordinated-manoeuvres-warning-placard-cancelled","history":"/api/acts/ad-pa-30-21-amdt-1-uncoordinated-manoeuvres-warning-placard-cancelled/history","analysis":"/api/acts/ad-pa-30-21-amdt-1-uncoordinated-manoeuvres-warning-placard-cancelled/analysis","conflicts":"/api/acts/ad-pa-30-21-amdt-1-uncoordinated-manoeuvres-warning-placard-cancelled/conflicts","importantCases":"/api/acts/ad-pa-30-21-amdt-1-uncoordinated-manoeuvres-warning-placard-cancelled/important-cases","documents":"/api/acts/ad-pa-30-21-amdt-1-uncoordinated-manoeuvres-warning-placard-cancelled/documents"}}
