South Korea has launched a safety inspection of all Boeing 737-800s operated by domestic carriers, a day after the deadly crash of a Jeju Air 737-800 that killed 179 people. The probe will take place between 30 December and 3 January for six carriers operating 101 737-800s in the country and will look into "the maintenance history of major systems such as aircraft engines and landing gears", states the country's Ministry of land, infrastructure and transport in a 30 December statement. Jeju Air, T’Way and Jin Air are the top three operators with 39, 27 and 19 of the type, respectively, the ministry details. The other three carriers are Eastar Jet, Korean Air and Air Incheon. Jeju Air flight number 7C2216 enroute from Bangkok to Muan crashed during landing on 29 December at 09:03 local time. The 737-800, bearing registration HL8088 (MSN 37541), deviated from the end of the runway and crashed into the outer wall of the airport before erupting into flames, states the carrier. Only two crew members out of 175 passengers – 173 South Koreans and two Thais – and six crew members survived the crash. Videos online show the aircraft skidding on its belly with unopened wing flaps and without its landing gear before crashing into the wall. Officials believe the accident was caused by a landing gear failure likely due to a bird strike, Korean news agency Yonhap reports, adding that an on-site investigation has begun. The report details flight data recorder and the cockpit voice recorder have been retrieved but “it could take months for the exact cause to be determined”. At a 29 December briefing, Korea’s land ministry says Muan’s airport control tower had warned of a bird strike at 8:54, after which the pilot declared mayday at 8:59 a.m., per the news report. The US National Transportation Safety Board, Federal Aviation Administration and Boeing are also assisting Korea’s Aviation and Railway Accident Investigation Board in the investigation. Fleet data shows the 2013-vintage aircraft is powered by CFM International CFM56-7B26 engines and was on operating lease from SMBC Aviation Capital. The aircraft was leased to Jeju Air in 2017 and was previously operated by Ryanair. Jeju Air has 38 737NGs and two 737 Max 8s in service and stored on its fleet excluding the HL8088 which has been written off, fleet data shows. A day after the crash, a Jeju Air flight 7C101 flying from Gimpo International airport to Jeju on a 737-800 was forced to return shortly after takeoff due a landing gear issue.
