China's civil aviation regulator on Tuesday urged the immediate launch of a two-week-long safety overhaul of the civil aviation sector after a passenger plane crashed in China the day before. In addition to previous safety supervision and guidance, the safety overhaul aims to further strengthen the investigation of hidden dangers in the civil aviation sector to ensure the absolute safety of aviation operations and people's lives, the Civil Aviation Administration of China said in a circular.

民航局3月22日下发通知，要求在前期行业安全督导工作的基础上，立即开展为期2周的行业安全大检查，旨在加强民用航空领域安全隐患排查，确保航空运行绝对安全，确保人民生命绝对安全。

The overhaul covers all regional air-traffic management bureaus, companies involved in civil aviation transport and general aviation, service providers, airport operators and flight training organizations, among other sectors.
此次安全大检查的范围包括各地区空管局、运输（通用）航空公司、服务保障公司、机场公司、飞行训练机构等。

No survivors have been found so far after a China Eastern Airlines plane with 132 people aboard crashed in South China's Guangxi Zhuang autonomous region.
