What happened while maintaining the airplane in a good, small business manner?

Around May 2007, Halla Sky Air, a small airline focusing on light aircraft, was founded on Jeju Island, but that company has now disappeared.

How did it disappear?

Halla Sky Air was originally a company that owned and operated about eight light aircraft.

In 2012, he was caught using cheap gasoline instead of jet fuel and was fined 3 million won.

As the company’s debt exceeded 1.8 billion won, it experienced management difficulties and reduced the number of aircraft it owned from 8 to 4.

In this situation, aircraft maintenance was handled by having personnel who did not know how to use tools create false measurement values.

As a result, aircraft engines are in a state of extreme deterioration, with parts worn out and metal dust entering.

Even the oil hose, which needs to be replaced every year, was not replaced in violation of the maintenance manual until the end of 2011, so engine oil was leaking out.

Since I couldn’t find the oil leak point, I just resorted to pouring water into the bottomless tank that regularly replenishes the leaked oil.

On February 18, 2016, a plane taking off for flying lessons at Gimpo Airport crashed, killing an instructor and a student instantly.

Halla Sky Air goes out of business after that incident.
