The directive is legally binding; flying these aircraft without completing this modification violates civil aviation regulations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-150-12-seat-belt-attachment","history":"/api/acts/ad-cessna-150-12-seat-belt-attachment/history","analysis":"/api/acts/ad-cessna-150-12-seat-belt-attachment/analysis","conflicts":"/api/acts/ad-cessna-150-12-seat-belt-attachment/conflicts","importantCases":"/api/acts/ad-cessna-150-12-seat-belt-attachment/important-cases","documents":"/api/acts/ad-cessna-150-12-seat-belt-attachment/documents"}}
