Accident summary 2007（Heisei 19 years ）March 13、All Nippon Airways Flight （ ANA）1603、Osaka International AirportDeparted at 8:09 amKochi AirportIt was operated as a go. Flight 1603 is the second flight from Osaka to Kochi, which is operated by a subsidiary company.Air central（ currentANA Wings） was doing.. The aircraft had been in service in All Nippon Airways since 2003, and was relatively new aircraft.

Flight 1603 at 8:49 am Kochi Airport "I tried to move to the landing posture. However, there was a report that 「 nose gear （ front wheel ） does not appear 」. Normal hydraulic In addition to the operation by, it was an aircraft designed to allow the front wheels to be carried out manually, so Flight 1603 tried to put out the front wheels manually, but failed this, and the front wheels were lowered by impact during landing. Trying to dropTouch and GoI repeated it but did not succeed."

Because of this, the Captain, as a last resort, decided to do a torso landing. At emergency because the accident aircraft is a small aircraft fuel dump After not equipped with the equipment to be installed, I turned over the airport for two hours and consumed fuel, and entered the emergency landing at Kochi Airport. At this time, at Kochi AirportrunwayWas closed and an emergency vehicle such as a fire engine was waiting beside the runway. There were media outlets and police personnel gathered by the news reports on the side of the airport. Also, the appearance of this emergency landing was broadcast nationwide by many TV stations broadcast live.

Flight 1603 decided to land on the fuselage at 10:54 am, after gliding for about 15 seconds with only the main gear （ rear wheel ） grounded on the runway and the nose kept horizontally upwards. Slow down while gently lowering the nose and touching the runway、After 15 seconds after the nose touchdown, it stopped successfully and successfully landed. There were no injuries to 60 passengers as the lower nose caused a spark when the grounded, but no fire broke out and there was less impact on landing. Both main gears had less effect on the left and right balance, and no damage caused by the propeller blade's contact with the ground.[Note 1]This minimized damage to the aircraft. There was a black scuff on the aircraft about 5 meters from the front-legged containment door, and the communication antenna for the control tower communication at the bottom of the aircraft had a damaged tip, but only the damage to the fuselage.

In the event of this accident, Kochi Shimbun was upset by the height of the captain's skill for proper emergency landing operations.[1].

The direct cause of the absence of the front wheels was a cylindrical part （ sleeve ） worn on the arm that moves the opening and closing doors of the front wheel hangar, but on the side of the aircraft, offset by the original mounting position. It was caught. Also fix the cylindrical partsboltOne was lost. Manual operation of the backup also did not work, as the cylindrical parts that had to be bolted gradually slipped on the side of the aircraft and locked each time the takeoff and landing was over. The Accident Investigation Commission said it was likely that the bolts were missing from the manufacturing process of the accident aircraft, as there were no traces of bolts on the cylindrical parts joining the front leg door that caused the accident. It has solidified the view. Since it was not on the checklist in the manufacturer's manual, Hikai has not performed the inspection maintenance itself in the relevant part since its receipt in July 2005. Therefore, the cause of the accident is a high suspicion of rudimentary manufacturing mistakes. In contrast, Bombardier has acknowledged manufacturing mistakes on the major sources, and it is likely that it was a mistake that occurred when the entire front leg was replaced after testing before the delivery of the machine. Accordingly, a final survey is underway in the direction of pointing out the deficiencies in Bombardier's manufacturing management system.[Five]. As mentioned later, since the parties died, there are frequent torso landing accidents caused by the main legs overseas.

Accident cause investigation report May 28, 2008、Ministry of Land, Infrastructure and TransportAviation/Railway Accident Investigation CommitteeAnnounces Accident-Cause Report of Forgotten Bolt on Front Ring Retractor at Blocking Arm Butt on Repair When Opening and Closing Equipment Damaged in a Pre-Delivery Test at Bombardier, Canada[3]Shih[Review]、Called on Transport Canada to lead the company's quality control system[6]. 「 Vice President Todd Young of the company apologizes again for deeply frightening 」 many people's concerns and annoyances at a press conference, 「 embodying a repair manual after an accident. We implemented 5 stages of improvement. Confident in safety 」[7].

Post-accident Criticism of the accident and subsequent troubles 「Bombardier aircraft aviation accident and incidentSee also 」 The cause of the accident was due to the fact that the manufacturer forgot to bolt it when repairing the damage during the pre-delivery inspection that was done in the final stages of manufacturing, but despite frequent operating problems with the isomorphic aircraft、The operation continued without even identifying the cause. The reason for this is thatYS-11There is a view that it was the main aircraft of the local line with the successor aircraft, or because it was the few 50-70 class turboprop aircraft that Japan could introduce. The anxiety about major accidents has increased from the people of Kochi Prefecture.[8]、After the accident, users and travel agency branch managers criticized the sky all day long[9].

No one was injured, but the first serious thing on the planeincidentwas. Introduced isomorphic aircraftJapan AirlinesTrouble continued in the group, but it did not reach an accident like the sky all day.

The DHC8-Q400, which became an accident aircraft, has been aware of poor operation of the hydraulic system that stores the main legs before this accident, oil leaks, and poor wiring due to design errors and electronic device failures、There were many cases of turning back after canceled due to aircraft maintenance and after takeoff （ 77 cases including the accident from 2005 to 2007 ）[Ten]. I also had 88 troubles from 2002 when I entered service to the accident[11]. Further in September 2007Scandinavian AirlinesAt the isomorphic aircraft of Japan Air Commuter, which was over 10,000 hours of operation at the direction of the emergency inspection of the Ministry of Land and Transport, due to a series of accidents in which the left main leg was divided and the fuselage landed during landing. 3 aircraft、Two aircraft from all-day sky groups, which had exceeded 9,000 hours, were discontinued. In October of the same year, the company was hit by the Scandinavian Airlines accident, which had been repeated since September, and the number of defects was performed by the Japanese Air Commuter and 24 isomorphic aircraft in the sky all day long.[12].

Previously in the all-day sky group DHC8-Q400, on November 21, 2004Air Nippon NetworkA flight operated by will deviate from the runway at Kochi Airport and shut down the airport that cannot move by the side of the runwayOverrun accident[13]Hi, on February 9, 2006, the wheels of ANA1823 were completely out before landing, and I had trouble manually lowering them. On March 20Amakusa AirlinesDHC8-Q100 of is no longer available at Kumamoto Airport, and there is a problem to manually remove all wheels. Subsequent incidents occurred in 2008, and on August 12, the Japanese Air Commuter isomorphic aircraft （JA848C）、A serious incident in which the runway is closed due to trouble of damaging the engine and splitting metal pieces on the runway just before taking off from Osaka International Airport （ Aviation Law Enforcement Regulation Article 166-4 No. 6 「 Movering Has caused 」, which is applicable to ）、The trouble of the isomorph has not been eradicated.

Scandinavian Airlines also had a fuselage landing accident in Norway on October 27, 2007, after the aforementioned serial accident, and on that day 「 no longer regaining trust from customers 」 As an isomorph. The operation was canceled and retired from the line. In 2004, as an example of the discontinuation of Bombardier's aircraft due to an accidentChina Eastern AirlinesofCRJ-200（ Later found to be due to improper aircraft management ） （China Eastern Airlines Flight 5210 crashSee ）.

Accident coverage Immediately after the accident、Mass mediaIt was sometimes written in the press as 「 Bombardier fuselage landing 」. In NHK, we made the expression 「 All-day air group passenger aircraft 」 that landed at Kochi Airport.[14].

After the accident machine

JA849A （ March 19, 2007 ） The aircraft that caused the accident （ JA849A） was refurbished to the extent that it could fly at a minimum in May 2007.SendWas done. There was a full-scale renovation work, and the part of the front fuselage that came into contact with the runway was completely replaced. In September, I passed a safety inspection by the Ministry of Land, Infrastructure and Transport and received permission to re-commit as an airliner. However, in the wake of a continuous Scandinavian aircraft accident, the entire-day sky voluntarily took measures to de-operate and inspect aircraft that had been flying for more than 9,000 hours, so it would return to line operation. There was no. On October 21st, the Hikai is about JA849A 「 You need to be relieved by flying 」 from Itan Airport for use as a training aircraft for long-term flight crews.Okinawa PrefectureofSubland Island AirportSent to[15]. Also, Air Central crewTrade unionWas done after the accidentstrikeIn, the same model maintenance system was strengthened in the request item.

On December 19, 2007, the Hikai 「 took off and landed more than 100 times and claimed that there was no abnormality 」, and the aircraft was treated as Osaka on January 1, 2008, saying that safety was okay. （ It was announced that it would return to line operation from the first flight to Hidetsu. However, in Kochi PrefectureTail ⁇ honestWithdrawal of policy as governor expressed regret[16]did. On June 23, 2008, Hikai announced that it will order three additional DHC-8-400s and introduce it after 2010, and sell JA849A to Bombardier.[17]did. JA849A was deregistered on March 26, 2010, and after the Bombardier owned aircraft （ aircraft symbol: C-GDXC ）, from 2012 in MongoliaEznis AirlinesIt was handed over and operated as the aircraft symbol JU-9919. In November 2014Nordic Aviation CapitalAfter being sold to and becoming the aircraft number OY-YAH, it was sold to Sky Service Business Aviation in June 2015 and became the aircraft number C-GSXA. In March 2016AuroraSold to and became aircraft number RA-67252.

Discussions held on the demand for the introduction of alternative models

This article needs updating. Old information appears in this article. New information in articles when editingReflectionlet me do it. Please remove this tag after reflection.（December 2022） Immediately after the accident, the Department of Land, Infrastructure and Transport made an unusual request for improvement from manufacturers and the Government of Canada[18]. againNamoku CityThe mayor gave the city council the idea of urgently applying for the sky all day, such as the introduction of alternative aircraft.[19].

However, it was equipped with a turbofan engine that had not been long since it was purchased and had a low fuel economy and low noise even on small passenger aircraft for rural routes where turboprops were mainstream.Regional jetWas introduced and was producing a turboprop that was in competition with the DHC-8-400SwedenofServeDiscontinued to manufacture turboprops of this size、GermanyofFairchild DornierYayNetherlandsofFokkerThe company disappeared due to a business failure, and the manufacturer focused on regional jets, and the reorganization of the industry was progressing. Therefore, there is no plan for new development[20]、Osaka （ Itami ） • Turboprops that can fly to Kochi Line are slightly older turboprops with poor cruising performance and fuel economy （Il-114、An-140、Y-7If you exclude ）、ATR companyofATR 72Only[Note 2].

Not only is economics the reason why there are many turboprops such as the DHC-8-400 in Japan, but also the noise of residents near Osaka International Airport, which was violently held at Osaka International Airport in the 1970s. In response to the opposition movement、In 1977, 「 jets had conditions such as less than 200 flights per day 」, and many regional jets equipped with low-noise turbo fan engines that have appeared since the 2000s are noisier than turbo prop aircraft. Despite the low noise, no legislative revisions have been made、Other than this, one of the two runways has the background that more turboprops are not regulated, as only small machines can be used in length relationships. There are many DHC-8-400s operating on the route between Osaka and Kochi in the form of receiving that area.

When the DHC-8-400 was previously suspended due to aircraft troubleshooting, the full-day sky was a high-quality lineAirbus A320（ 166 seats ） replaced, but at this timeKansai International AirportIncoming （ The number of flights has been significantly reduced because the opening line of Osaka International Airport cannot be used and the number of seats provided is the same. Also, the full-day sky is a little more passengers than the DHC-8-400Mitsubishi SpaceJetWe have ordered （SpaceJet M90 and 90 seats ）, which will be a low noise aircraft aimed at entering Osaka International Airport. However, there was a movement to reduce the jet frame itself at Osaka International Airport, and at the earliest, the service was postponed after 2012 （ and discontinued ）, and the appropriate aircraft to replace DHC-8-400 was ordered. Has not been done. Japan Airlines is also close to SpaceJetEmbraer 170Although ordered but low noise, it is a jet aircraft and no turbo prop machine is ordered to replace the DHC-8-400.[Note 3][Note 4].

In addition to this, the Japanese aviation industry also provides parts for Bombardier aircraft, and there may be advantages to parts support.
