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.

On Sunday, a Jeju Air plane traveling from Bangkok's Suvarnabhumi International Airport crashed at a South Korean airport, killing 179 people. It was carrying 181 passengers and crew members. Jeju Air's stock slumped as much as 16% and closed 8.7% lower on Monday.

Boeing is in red today after South Korea ordered a “comprehensive special inspection” of all B737-800s – the aircraft involved in the Jeju Air crash that killed 175 passengers over the weekend. The deadly incident has once again raised significant concerns about aviation safety.
