SB No. 01) before 31 January 1985.\n\n**Why it matters:** A jammed buckle could trap passengers in their seats during an emergency, preventing evacuation. While earlier directives addressed helicopters that had these belts fitted at the factory, this directive also covers belts that may have been installed on other aircraft afterwards as replacements or upgrades."}},"importantCases":[],"_links":{"self":"/api/acts/ad-res-18-securaiglon-ex-l-aiglon-safety-belts-modification","history":"/api/acts/ad-res-18-securaiglon-ex-l-aiglon-safety-belts-modification/history","analysis":"/api/acts/ad-res-18-securaiglon-ex-l-aiglon-safety-belts-modification/analysis","conflicts":"/api/acts/ad-res-18-securaiglon-ex-l-aiglon-safety-belts-modification/conflicts","importantCases":"/api/acts/ad-res-18-securaiglon-ex-l-aiglon-safety-belts-modification/important-cases","documents":"/api/acts/ad-res-18-securaiglon-ex-l-aiglon-safety-belts-modification/documents"}}
