It looked like the nose gear was still contained within the fuselage,” he told CNA’s Asia First a day after the tragedy.\n“This appears to be a very uncommon occurrence. Bird strikes affecting landing gear is something that I've never heard of.”\n\n\n\n\n\n\n\n\n\n\n\n\n\nIndependent aviation analyst Alvin Lie added: “If a bird hits one of the engines, the worst thing that can happen is the engine shuts down. Bird strikes do not cause the landing gear to fail or the flaps not to be able to be extended. So, there must be other reasons.”\nARE BIRD STRIKES COMMON?\nBird strikes are a relatively common problem for aviation, but rarely result in serious accidents.\nLast year, the United States recorded an average of 54 wildlife strikes per day, according to the US Federal Aviation Administration (FAA). Most of the strikes involved birds although wildlife also includes animals like deer.\nAbout 90 per cent of bird strikes happen near airports, when an aircraft is taking off or landing, or flying at lower altitudes, according to the International Civil Aviation Organization.\nThe most famous bird strike incident occurred in 2009 when a US Airways plane made an emergency landing on the Hudson River in New York after striking a flock of geese. All 155 crew and passengers onboard survived.\nExperts said bird strikes may shut down an engine or in rare cases, two – like the Airbus in the Hudson River incident, but planes remain unaffected in most cases.\nLANDING GEAR AND RUNWAY WALL\nAnalysts are puzzled over why the plane touched down without landing gears, saying it is unusual as there are alternative systems to lower them.\n“The bird strike (might have) caused a total electrical malfunction of the aircraft, but the pilots should still have been able to release those wheels in some way,” said aviation analyst Paul Charles.\n“We have to let the investigators discover if the engines were at fault, or there was another mechanical issue which was exacerbated by the bird strike.”\n\n\n\n\n\n\n\n\n\n\n\n\n\nFootage showed the plane disintegrating as it skidded along the runway before ultimately slamming into a wall at high speed in the overrun area, exploding into flames.\nExperts said there could have been fewer casualties if the runway did not end with the solid structure.\n“It seems the plane was engulfed in fire because it hit the wall. Why is there a massive concrete wall in the perimeters of the airport? There are supposed only to be fences, not massive walls,” said Lie.\nHowever, South Korea’s deputy transport minister Joo Jong-wan said the runway's 2,800m length was not a contributing factor, and that walls at the ends were built to industry standards.\nSOUTH KOREA, 737-800 TRACK RECORD\nThe twin-engine 737-800 jetliner has a strong safety record and is considered a dependable and popular aircraft for short-haul flights, said analysts. \nThere are about 4,000 of the aircraft model in service, used by some 200 airlines, accounting for 15 per cent of the total number of planes flying in the world.\n“This is a plane that a lot of carriers rely on… it's generally seen as the workhorse of short hops under five hours. Overall, it has a really good safety record,” said Charles.\n\n\n\n\n\n\n\n\n\n\n\n\n\nSouth Korea is considered among the safest countries for air travel in recent times, with experts saying it has an excellent record with maintenance, repair and overhaul.\nJeju Air is South Korea’s largest low-cost carrier, operating about 40 planes, most of them 737-800s.\nThe crash on Sunday was the airline’s first fatal accident since it was founded in 2005. \nThe doomed jet was about 15 years old, and was previously flown by Ryanair until 2017, when it was transferred to Jeju Air.\nIt was arriving from Thailand’s capital Bangkok and was reportedly in good mechanical conditions, said analysts.\nINVESTIGATIONS BEGIN\nSouth Korea's aviation authority is investigating the crash, assisted by America's National Transportation Safety Board, FAA and Boeing.\nThe flight and voice recorders from the plane have been recovered, and will shed light on its final moments. However, Yonhap reported that the flight recorder was retrieved partially damaged, which will complicate the investigation process.\nA flight recorder tracks an aircraft's performance and condition, while the cockpit voice recorder will reveal communications between the pilots in the cockpit and the ground.\nAnalysts said multiple questions remain, including whether technical issues encountered on the plane two days before the incident had anything to do with its ultimate demise.\nLast Friday, the plane was on a routine flight from Jeju to Beijing when it was diverted to Incheon, South Korea’s main airport. The flight later continued to the Chinese capital.\nExperts said it will take investigators at least several weeks to decode the recorders and fully analyse the information.\n“There are a lot of questions which we need to find the answers to, and we really have to look at the data … to find the exact cause of the crash and issue recommendations to prevent similar incidents,” Lie said.","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"symbols":[],"gpt_button":1},"commentList":[],"hasMoreComments":false,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false}}
