The diaphragm is the structural base of the seat cushion, and this ensures it won't fail during flight or block emergency exit.\n\n**Who is affected:** Anyone operating these specific Aerostar aircraft under Australian aviation safety regulations must ensure compliance or ground the aircraft."}},"importantCases":[],"_links":{"self":"/api/acts/ad-tsa-600-10-pilot-and-passenger-seat-cushion-diaphragm-inspection-and-modification","history":"/api/acts/ad-tsa-600-10-pilot-and-passenger-seat-cushion-diaphragm-inspection-and-modification/history","analysis":"/api/acts/ad-tsa-600-10-pilot-and-passenger-seat-cushion-diaphragm-inspection-and-modification/analysis","conflicts":"/api/acts/ad-tsa-600-10-pilot-and-passenger-seat-cushion-diaphragm-inspection-and-modification/conflicts","importantCases":"/api/acts/ad-tsa-600-10-pilot-and-passenger-seat-cushion-diaphragm-inspection-and-modification/important-cases","documents":"/api/acts/ad-tsa-600-10-pilot-and-passenger-seat-cushion-diaphragm-inspection-and-modification/documents"}}
