The directive doesn't list the specific inspection steps itself—it requires compliance with that separate technical document.\n\n**Why it matters:** The inspections are designed to catch cracks in the airframe before they cause the cabin to lose pressure or, in a worst-case scenario, lead to structural failure. This is a safety-critical measure to keep the aircraft airworthy.\n\n**Note:** There is a related Israeli airworthiness directive (No. 91-01) that also addresses this issue."}},"importantCases":[],"_links":{"self":"/api/acts/ad-iai-w-15-structural-inspection-program","history":"/api/acts/ad-iai-w-15-structural-inspection-program/history","analysis":"/api/acts/ad-iai-w-15-structural-inspection-program/analysis","conflicts":"/api/acts/ad-iai-w-15-structural-inspection-program/conflicts","importantCases":"/api/acts/ad-iai-w-15-structural-inspection-program/important-cases","documents":"/api/acts/ad-iai-w-15-structural-inspection-program/documents"}}
