The old rule required specific actions regarding the High Pressure Compressor.\n\n**Why it matters:** Operators no longer need to follow the specific Australian maintenance instructions from the earlier directive. Instead, they must comply with a newer European safety standard (EASA AD 2009-0273-E) that deals with the same engine issue. This aligns Australian rules with international regulations, avoiding duplicate requirements."}},"importantCases":[],"_links":{"self":"/api/acts/ad-br700-8-high-pressure-compressor-cancelled","history":"/api/acts/ad-br700-8-high-pressure-compressor-cancelled/history","analysis":"/api/acts/ad-br700-8-high-pressure-compressor-cancelled/analysis","conflicts":"/api/acts/ad-br700-8-high-pressure-compressor-cancelled/conflicts","importantCases":"/api/acts/ad-br700-8-high-pressure-compressor-cancelled/important-cases","documents":"/api/acts/ad-br700-8-high-pressure-compressor-cancelled/documents"}}
