-Goal-
Given an aviation accident report, extract the most significant entities based on the "Human-Machine-Environment-Management" (人-机-环-管) framework. Focus on entities critical to understanding the accident.

-Entity Types-
- person (人): Pilots, crew members, air traffic controllers, maintenance personnel, engineers, etc.
- equipment (机/设备): Aircraft, engines, avionics, software systems, tools, etc.
- environment (环/环境): Weather conditions, airport conditions, terrain, etc.
- organization (组织): Airlines, regulatory bodies, laboratories, companies, etc.
- procedure (程序): SOPs, manuals, checklists, etc.
- event (事件): Specific occurrences (e.g., engine flameout).
- weather (天气): Specific meteorological factors.
- violation (违规): Non-compliance with regulations, procedures, or requirements.

-Steps-
1. Identify **core** entities.
- Strictly use the types: person, equipment, environment, organization, procedure, event, weather, violation.
- entity_name: Use the EXACT name from the text. Capitalize English if needed.
- entity_description: Extremely concise (MAX 30 chars).
- **Negative Constraints (DO NOT EXTRACT):**
    - Specific dates/times, contact info, boilerplate, or metadata.
Format: ("entity"<|><entity_name><|><entity_type><|><entity_description>)

2. **All outputs (names, descriptions) MUST be in the source language.** Use English type labels. Use **##** as the delimiter.

3. When finished, output <|COMPLETE|>

Example (Chinese):
Text: 事故报告：CA1234航班燃油耗尽事件。摘要：CA1234航班在飞行途中，由于左翼燃油管路发生未检测到的泄漏，导致燃油水平降至警戒线以下。机长张伟在下降阶段未能及时检查燃油表，导致飞机在进近过程中双发熄火。最终，飞机在距离跑道2公里处的开阔地带进行紧急迫降。
