This had to be done within 200 hours of flight time after November 1976, following specific manufacturer guidelines (Ted Smith Corporation Service Bulletin No. 600-51).\n\n**What this document does:** It **cancels** that safety requirement entirely. As of 4 June 2009, aircraft owners no longer need to perform this specific inspection or replacement.\n\n**Why it matters:** If you own or operate one of these aircraft, you are no longer legally required to comply with the seat bolt inspection mandated by the original 1976 directive. This reduces maintenance obligations for these older aircraft models."}},"importantCases":[],"_links":{"self":"/api/acts/ad-tsa-600-1-amdt-1-pilot-seat-back-rest-attach-bolt-inspection-and-replacement-cancelled","history":"/api/acts/ad-tsa-600-1-amdt-1-pilot-seat-back-rest-attach-bolt-inspection-and-replacement-cancelled/history","analysis":"/api/acts/ad-tsa-600-1-amdt-1-pilot-seat-back-rest-attach-bolt-inspection-and-replacement-cancelled/analysis","conflicts":"/api/acts/ad-tsa-600-1-amdt-1-pilot-seat-back-rest-attach-bolt-inspection-and-replacement-cancelled/conflicts","importantCases":"/api/acts/ad-tsa-600-1-amdt-1-pilot-seat-back-rest-attach-bolt-inspection-and-replacement-cancelled/important-cases","documents":"/api/acts/ad-tsa-600-1-amdt-1-pilot-seat-back-rest-attach-bolt-inspection-and-replacement-cancelled/documents"}}
