South Korea’s leading low-cost carrier, heavy with debt and its stock already near record lows, is now facing intense public and government scrutiny.

Officials are inspecting the black boxes recovered from the wreckage of Jeju Air flight 7C2216 and have promised to release updates as soon as possible. The Boeing 737-800 is believed to have suffered a bird strike, but the exact circumstances surrounding its belly landing and subsequent destruction are unclear.

The South Korean government has said it will conduct a safety inspection of all Boeing 737-800 aircraft used by domestic airlines after the Jeju Air crash on Sunday, and another plane fault on Monday morning, according to a local news source.
