It requires owners and operators of specific Eros brand full-face oxygen masks used in aircraft to carry out urgent safety work.\n\n**What it does:**\n- **Identifies the problem:** Certain Eros oxygen masks (18 specific part numbers listed) need inspection and modification to ensure they work properly in an emergency.\n- **Sets two deadlines:**\n  - **By 30 May 1992:** Inspect the masks following Eros Service Bulletin MF 10-35-43.\n  - **By 31 January 1993:** Modify the masks following one of two specified Eros Service Bulletins (MF 10-35-46 or MF 10-35-44).\n\n**Who it affects:**\n- Aircraft operators, maintenance organisations, and owners using these specific Eros oxygen mask models in Australian-registered aircraft.\n\n**Why it matters:**\n- Oxygen masks are critical safety equipment for pilots and passengers at high altitudes. This directive prevents potential mask failure that could lead to hypoxia (lack of oxygen) during flight emergencies. The directive references a French aviation safety notice (DGAC AD 91-175), indicating this addresses a known international safety concern."}},"importantCases":[],"_links":{"self":"/api/acts/ad-oxy-8-eros-full-face-oxygen-masks","history":"/api/acts/ad-oxy-8-eros-full-face-oxygen-masks/history","analysis":"/api/acts/ad-oxy-8-eros-full-face-oxygen-masks/analysis","conflicts":"/api/acts/ad-oxy-8-eros-full-face-oxygen-masks/conflicts","importantCases":"/api/acts/ad-oxy-8-eros-full-face-oxygen-masks/important-cases","documents":"/api/acts/ad-oxy-8-eros-full-face-oxygen-masks/documents"}}
