It requires owners to inspect the **rudder bar assembly**—the foot pedals that steer the plane on the ground—within 100 hours of flying time after 31 December 1973, and then again every 100 hours until a permanent fix is installed. The permanent modification must be done following Piper's Service Letter No. 671, and must be completed no later than the aircraft's first major inspection after 31 December 1973.\n\n**In plain terms:** Check the rudder pedals regularly for a set period, then get them permanently fixed by your next major service."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-32-29-rudder-bar-assembly-inspection-and-modification","history":"/api/acts/ad-pa-32-29-rudder-bar-assembly-inspection-and-modification/history","analysis":"/api/acts/ad-pa-32-29-rudder-bar-assembly-inspection-and-modification/analysis","conflicts":"/api/acts/ad-pa-32-29-rudder-bar-assembly-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-pa-32-29-rudder-bar-assembly-inspection-and-modification/important-cases","documents":"/api/acts/ad-pa-32-29-rudder-bar-assembly-inspection-and-modification/documents"}}
