The South Korean government has formed an aviation safety committee that should present its findings in March.

South Korea aims to rebuild its aviation safety system from scratch, the transport ministry said on Tuesday, launching a new committee to improve air travel in the country that suffered two major aviation incidents a month apart.

South Korean authorities concluded search and recovery operations and an investigation into the Dec. 29 crash of a Jeju Air plane that killed 179 people and found feathers and bloodstains in the two engines of the plane.

The report also said the plane’s two black boxes — the flight data recorder and cockpit voice recorder — stopped recording about 4 minutes before the crash. This could complicate efforts to find the cause of the crash.

The 10-week committee will include private sector experts and will look at issues including maintenance and aircraft utilization rates at budget airlines
