The EgyptAir flight MS804 crash latest update has revealed that the plane had to make three emergency landings a day before crashing and plunging into the Mediterranean Sea.

The plane en route to Cairns from Paris with 66 people on board composed of 56 passengers and 10 crew members went missing from radar and reported to have crashed later on. The incident took place on May 19. Euronews reported that the Airbus A320 was permitted to make an emergency landing on three occasions the day previous to when the plane crashed. The inconsistency was observed during the plane’s six rotations during its journey between Asmara in Eritrea, Cairo, and Tunis according to The Telegraph UK. Despite reflecting some technical abnormalities, the EgyptAir flight was allowed to take off for the Paris to Cairns journey.

Euronews reported that the plane’s warning system, ACARS, was unreachable every time it took off. “We cannot presume to know exactly what happened on board but it’s not entirely normal to turn around several times after a technical incident without finding anything,” Jean-Paul Troadec, former aviation security officer, told TV channel France 3. The aviation engineer also said that the ACARS remains silent when it functions properly while it emits signals automatically at the time of its malfunctioning.

On the other hand, EgyptAir Chairman Safwat Musallam denied the claims of three emergency landings. “For me it is not true,” he said while on his trip to Dublin for the International Air Transport Association (IATA) annual meeting. He added that he trusted his aircraft officials and pilot. According to him, the flight did not experience any technical or maintenance issues before departing from Paris. It was all “normal,” the airline’s chairman said.

News.com.au reported that it is still unknown why the plane made violent swerves prior to crashing into the Mediterranean. It is believed that the authorities will come forward to answer the questions this week on the claims made by Euronews.
