early discoveries

Investigators from the Korean Air and Rail Accident Investigation Board (항공・철도사고조사위원회, ARAIB) found bird feathers and blood in both engines of the plane, Reuters reported, citing sources. I told you. boeing 737-800
It crashed at Muan International Airport (MWX).

Previous reports had suggested that the bird strike was the beginning of a chain of events that ultimately led to the attempted landing at the airport, including the discovery of feathers and blood on one of the engines. A twin-engine Bird Strike is a possibility. Please explain why both the cockpit voice recorder (CVR) and flight data recorder (FDR) stopped recording four minutes before the 737-800 hit the concrete structure at the end of the runway.

The latter development was confirmed by South Korea's Ministry of Land, Infrastructure, Transport and Tourism (국토교통부, MOLIT) on January 11, adding that it would investigate why the two recorders stopped working.

“While CFR and FDR are important for accident investigation, accident investigation is done through the analysis of various datasets, so we want to do our best to accurately identify the cause of the accident.”

According to an old study by the European Union Aviation Safety Agency (EASA), “aircraft collisions are significantly more common than engine collisions (4.6 to 1 ratio)”.

safety violation

“The main improvements include reflecting training in which two or more engines are shut down in the training manual and regularizing the training, unifying bird strike response procedures in pre-flight briefings, unifying standards for calculating aircraft utilization rates, and regularizing the training. This includes implementing and reviewing management plans, conducting training, etc., and improving them. ”

The ministry also completed a safety survey of navigation facilities across the country's airports, noting that adequate safety measures are in place and well maintained. At the same time, seven airports and nine facilities, including Muan International Airport, need improvement.

“In order to more accurately diagnose the safety systems of airlines, the Ministry of Land, Infrastructure, Transport and Tourism will expand the scope of inspections to include all models of 11 domestic airlines, and will conduct comprehensive safety inspections from January 13th to 31st.”
