Salvage crews found bodies and a wing section from an Air France jet that plunged into the Atlantic as investigators yesterday probed a possible link between false speed measurements and the crash.
Six days after Air France flight 447 from Rio de Janeiro to Paris disappeared while flying through violent storms in the middle of the night with 228 passengers and crew on board, speculation is focusing on its airspeed monitors.
Brazilian naval and air force crews found two bodies on Saturday and were continuing to come across wreckage, including part of the twin-engined Airbus A330’s wing as well as floating luggage, yesterday.
“As well as the bodies there are various remains of the aircraft. Plane seats, part of the wing and various other items were localized,” air force spokesman Lieutenant Colonel Henry Munhoz told reporters in Recife.
The doomed jet broadcast a series of 24 automatic error messages as its systems shut down one-by-one in its final minutes, and French accident investigators say the cockpit was receiving conflicting speed data.
Following the crash, Airbus warned pilots to review their methods to cope with this problem and Air France said on Saturday that it had accelerated existing plans to replace the monitoring units in its jets.
The device in question is the pitot probe, usually on the leading edge of a wing, which measures the force of the air through which an aircraft passes.
French Transport Minister Dominique Bussereau said it was too early for investigators to say what was the most likely cause of the crash, but confirmed that Airbus jets had experienced problems with speed monitors.
“There have been situations on Airbus planes, and perhaps on others, where these probes ice up in a very wet area, a deep depression, an area of storms, and no longer give the correct speed reading,” Bussereau told RTL radio.
“It’s obvious that if the pilots in the cockpit no longer have the correct speed in front [of them] that can lead to two bad consequences for the survival of the plane,” he said. “Too low a speed, which can cause it to stall, or too high a speed, which can lead to the plane ripping up as it approached the speed of sound, as the outer skin is not designed to resist such speed.”
A French nuclear submarine has been dispatched to the zone to help in the search, a race against time to find the black box flight data recorders in deep waters before they stop emitting a locator signal in a month’s time.
Other evidence found in the seas is being brought to the Fernando de Noronha archipelago, the closest inhabited spot to the zone where they were found, for initial inspection by forensic police.
From there, they were to be flown to Recife for further analysis by French officials. Two male bodies the Brazilian navy recovered in the zone will also flown to Recife, Munhoz said.
A blue plane seat, a nylon backpack containing a computer and vaccination card, and a leather briefcase with an Air France ticket inside were the first objects plucked from the sea, officials said.
The discoveries took place 450km northeast of the Fernando de Noronha islands, which are 370km from the mainland. The precise spot was 70km northeast of the point of last communication with the plane.
MAKING A MOVE: Starting on Monday, short-term business travelers can apply for shorter quarantine periods, while transits of up to eight hours would be allowed The Central Epidemic Command Center (CECC) yesterday announced an easing of restrictions that would from Monday next week allow foreigners to visit or make a transit flight in Taiwan. A policy allowing short-term business travelers from countries with low or medium risks of COVID-19 infections to apply for shorter quarantine periods is also to resume that day. Minister of Health and Welfare Chen Shih-chung (陳時中), who heads the center, said that while the autumn-winter COVID-19 prevention program is to be extended after the end of this month, special conditions for foreign nationals to enter Taiwan would be restored from Monday. Foreign nationals
CONTINUED VIGILANCE: People would still be required to wear masks at eight types of public spaces and border controls would continue, Chen Shih-chung told reporters The government’s autumn-winter COVID-19 prevention program is to continue beyond Sunday, but eating and drinking on high-speed trains would be allowed from Monday, the Central Epidemic Command Center (CECC) announced yesterday. Minister of Health and Welfare Chen Shih-chung (陳時中), who heads the center, said that while there were no new confirmed cases in Taiwan yesterday, the global COVID-19 situation remains serious, so the autumn-winter COVID-19 prevention program would be extended beyond its Sunday deadline. “Border control measures, including requiring a negative polymerase chain reaction test result obtained within three days of boarding a plane to Taiwan, and undergoing quarantine in a
‘UNFRIENDLY’: COA Minister Chen Chi-chung said that Beijing probably imposed the sanction because the pineapple production season is about to start in Taiwan More than 99 percent of pineapples sold to China passed inspections, the government said yesterday, after China earlier in the day abruptly suspended imports of pineapples from the nation, which Taipei called an “unfriendly” move. From Monday, China is to stop importing pineapples from Taiwan, the Chinese General Administration of Customs said. The regulation is a normal measure for ensuring biosafety, China’s Taiwan Affairs Office spokesman Ma Xiaoguang (馬曉光) said in a news release later yesterday. Since last year, Chinese customs officials have repeatedly seized pineapples imported from Taiwan that carried “perilous organisms,” Ma said. Were the organisms to spread in China, they would
MORE RISK? Three Taiwanese family members were found to have the Brazilian variant, which CDC Deputy Director-General Philip Lo said might be more infectious From Wednesday, all travelers who have been in Brazil in the past 14 days are required to be quarantined at a centralized facility after arriving in Taiwan and undergo a COVID-19 test upon ending quarantine, the Central Epidemic Command Center (CECC) announced yesterday. Minister of Health and Welfare Chen Shih-chung (陳時中), who heads the center, said that starting from 12am on Wednesday, all travelers arriving from Brazil, including those who have transited through the country in the past 14 days, would have to stay at a centralized quarantine facility. “They will be tested for COVID-19 upon completing the 14-day quarantine, and they
