00:00On 9 August 2024, a Brazilian local airline saw the Wopas Linhas flight 2283 fall from the sky in a horrific manner in different videos.
00:12The ATR-72-500 was a Brazilian passenger aircraft heading from Cascavel to São Paulo.
00:21But just a few minutes before landing, it was hit by an accident, killing 57 passengers and 4 crew members.
00:30This was not only the first dangerous crash in Brazil since 2011, but it is also considered dangerous in Brazilian aviation history.
00:39In the video, it can be seen that the aircraft is free-falling and falling from the sky like a cut kite.
00:47After the release of the video, there has been a wave of fear among those who belong to the aviation industry.
00:53Because no matter what aircraft it is, it can never come down free-falling.
00:59The plane always glides down.
01:02So what was the reason?
01:04An investigation has been launched by the authorities, but what happened a few minutes before the crash that could be the reason for this accident?
01:14Welcome back to Zem TV's videos.
01:17The Wopas Linhas is a local airline in Brazil that mostly covers domestic destinations.
01:24They have 8 ATR-72-500 aircraft, one of which crashed on August 9.
01:31The ATR-72 has two turboprop engines, and the number 72 in its name shows its seating capacity.
01:40It was made by the aircraft manufacturer ATR in France and Italy, while this company also has a 50% share of Airbus, which shares its technology with ATR.
01:52Flight 2283's ATR-72-500 was 14 years old, which was purchased by Wopas Linhas from Indonesia's Pelita Air Service in 2022.
02:04As I said before, this airline mostly operates only at local destinations.
02:10According to the flight data record, it took off from Sao Paulo on August 9, 2024 at 9.06 a.m. and its destination was up to Cascavel, 700 km west.
02:22This trip was just fine, it landed safely in Cascavel at 11.17 a.m. after 2 hours and 11 minutes.
02:32The flight was already late according to its scheduled time, and it had to load passengers from Cascavel and go back to Sao Paulo.
02:41For this reason, after unloading, cleaning was done as soon as possible, and exactly 41 minutes later, it took off from Cascavel to go back to Sao Paulo.
02:51There were a total of 57 passengers and 4 crew members with the pilot on board.
02:5761-year-old Umberto Decompos was the flight captain, 35-year-old Danilo Santos was the first officer, and 2 female cabin crew were also present.
03:06You can see everything from takeoff to crash, what was seen on the radar screen.
03:13At 11.58 a.m. local time, Flight 2283 took a left turn as soon as it took off from Cascavel and started maintaining an altitude of 17,000 feet, which is also called cruising altitude.
03:27At 12.21 a.m., after 23 minutes of takeoff, the altitude of 17,000 feet was maintained.
03:34If you go straight from Cascavel to Sao Paulo, there is a very large mountain range in the middle,
03:40which is avoided by all ships either going over the Pacific Ocean in the east or passing over plain land in the west.
03:50Flight 2283 also took a slight left turn to bypass this mountain range and then started heading straight for Sao Paulo.
03:59According to the radar, the first hour and a half passed in a completely normal way, in which the altitude of the ship was around 17,000 feet and the ground speed was 460 km per hour.
04:11At 1.07 a.m., Flight 2283 took a sharp left turn and headed for Campinas city, from where it had to approach and land at Sao Paulo airport.
04:25At 1.20 a.m., when it was in the south of Campinas, its ground speed was reduced for the first time.
04:33As it was going ahead at a speed of 460 km per hour, it suddenly became 159 km per hour.
04:41The reason for this was not known yet, but at 1.21 a.m., the pilot maintained his ground speed back to 400 km per hour.
04:55So far, the pilot has not given any kind of information to the ATC.
05:00This was the point from where the ship had to head towards Sao Paulo airport.
05:05And on the radar, we can see that the pilot has started turning the ship right.
05:11But only after 13 seconds, at 1.21 and 15 seconds, when he was turning, the ground speed suddenly decreased and with it, the vertical speed, i.e. the speed at which the ship goes down or up, began to decrease.
05:28It was seen on the radar that the ship flying at 17,000 feet began to come down at a speed of 13,000 feet per minute, also turning round.
05:38And during this time, its ground speed, i.e. the speed at which it went ahead, decreased from 400 to 100 km per hour.
05:45In this whole process, it took only 1 minute and 14 seconds.
05:50That is, in such a short time, the ship fell directly on the ground from 17,000 feet.
05:55During this time, the ship was coming down at a speed of 180 feet per second, and the pilots probably didn't have enough time to let the ATC know about their situation.
06:08The place where the vertical speed of the flight began to decrease and the place where it crashed, there is only a distance of 1.3 km between them.
06:18The real reason behind this sudden fall will be known after the investigation.
06:23But according to the information available so far, the area in which the crash occurred,
06:28all pilots were given information about the freezing of the snow at an altitude of 12,000 to 21,000 feet.
06:36This is also called SIGMET Advisory, i.e. Significant Meteorological Information.
06:42If snow begins to freeze on the wings of the ship, it is quite dangerous.
06:47Because due to the snow, the aerodynamics of the ship changes and the air that gives it lift, that lift now decreases.
06:55Due to the freezing of the snow, the second problem is that the wings, rudders, ailerons, and elevators,
07:01which are the moving parts of the aircraft, get stuck between them and they cannot move.
07:07That is, despite the pilot's input, the ship will not be able to turn right or left.
07:13To avoid this, most modern aircrafts have an automatic heating system that does not allow snow to freeze on important parts.
07:21Some aircrafts have a special chemical sprayed on them before the flight that prevents snow from freezing.
07:29ATR 72500 has a variety of de-icing systems installed.
07:34Pneumatic de-icing boots are attached to its wings, which keep removing the snow from time to time.
07:41Similarly, de-icing systems are installed in its propellers, windshield, and engine.
07:47And despite all this, if there is a snow forecast from the beginning,
07:50the pilot tries to avoid that altitude or that place where there is a fear of freezing snow.
07:57After the crash, the black box of Flight 2283 has been recovered.
08:02And it is hoped that in the coming months, the real reason for this crash will be revealed.
08:08But for now, it is a mystery as to how the ship fell straight down from 17,000 feet.
08:16I hope you will like and share this video of ZemTV.
08:20Thank you very much for your loving comments.
08:23See you in the next great video.
