This includes inspections and permanent fixes (termination actions) to ensure the engine is safe.\n\n**Why it matters:** Engine fires in flight are obviously catastrophic. This directive ensures these specific engines are inspected and modified to eliminate a known fire risk in the engine's compression system."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pw100-5-amdt-1-intercompressor-case-fire","history":"/api/acts/ad-pw100-5-amdt-1-intercompressor-case-fire/history","analysis":"/api/acts/ad-pw100-5-amdt-1-intercompressor-case-fire/analysis","conflicts":"/api/acts/ad-pw100-5-amdt-1-intercompressor-case-fire/conflicts","importantCases":"/api/acts/ad-pw100-5-amdt-1-intercompressor-case-fire/important-cases","documents":"/api/acts/ad-pw100-5-amdt-1-intercompressor-case-fire/documents"}}
