Investigators investigating the disappearance of flight MH370 claim to have discovered a 90 kg cargo that was added to the cargo list only after take-off.
The French engineer Ghyslain Wattrelos, who lost his wife and two of his three children in the accident, presented a new report detailing the requests to investigative judges in Paris last week.
He says that even a container on the flight was overloaded, but no explanation was ever established.
Four French citizens were lost to MH370, and France is the only country with an investigation into the incident still in progress.
"It was … learned that a mysterious load of 89 kg had been added to the flight list after take-off," said Wattrelos Le Parisian.
"Even a container was overloaded, without anyone knowing why.
"The expert has no conclusion.
"It could be incompetence or manipulation. Everything is possible.
"This will be part of the questions for the Malaysians."
Wattrelos also stated that several versions of the flight passenger list contradict each other.
The incident theories also focused on a shipment of lithium batteries that were on board the aircraft.
Two months after the accident, NNR Global revealed that it had shipped 2453 kg of items on the plane, of which 221 kg were lithium batteries.
It had been suggested that the batteries could ignite a fire, but the idea was described as "highly unlikely" by the Malaysian government's final report on its accident investigation.
In another twist in the mystery of the aviation, French investigators reported that the pilot of the disappearance of Malaysia Airlines flight MH370 – Captain Zaharie Ahmad Shah – is thought to have had control of the plane "until end".
A team of investigators gave access to data from Boeing flights at the company's headquarters in Seattle, the obvious anomalies during the flight told the French media.
"Some abnormal turns made by the 777 can only be performed manually," said Le Parisian, citing an investigator, who was not named because he had signed a confidentiality agreement with Boeing.
"Someone was at the helm."
MYSTERY OF THE AVIATION
Flight 370 disappeared March 8, 2014 en route from Kuala Lumpur, Malaysia to Beijing with 239 people on board.
Just 38 minutes from the flight he lost contact with Malaysia Airlines.
The disappearance has been dubbed one of the greatest mysteries in the history of aviation.
The search for the missing aircraft, which has become the most expensive ever conducted, initially focused on the seas of southern China and Andaman.
The data from the aircraft's automated communications later identified a possible accident site somewhere in the southern Indian Ocean, but no wreckage could be found.
Malaysian and international investigators believe the jet veered thousands of miles off course compared to the planned route before plummeting into the Indian Ocean.
Estimates for the likely position of the aircraft could be made using data that shows its distance from a fixed satellite but requires knowledge of how fast the plane was going and in what direction before the accident .
If it was flying north, the possible positions could extend to the border between Kazakhstan and Turkmenistan to Thailand.
But if it was flying south, possible sites could go from Indonesia to the southern Indian Ocean.
Until now, debris has been found in the air on the beaches in Malaysia, Mozambique and Tanzania, and the authorities now believe the plane is more likely to be sunk in the Indian Ocean.
More than 30 bits of aircraft debris were collected from various locations around the world, but only three wing fragments that were washed along the coast of the Indian Ocean were confirmed by the MH370.
THE MAIN THEORIES OF THE MISSING OF MH370
Pilot or co-pilot suicide: Captain Zaharie Ahmad Shah may have intentionally killed the plan in a murder-suicide act. The report shows that the aircraft was deliberately deactivated, but investigators say they found nothing irregular with Mr. Shah's background, training and mental health. Also the MH370 may have been shot down by the co-pilot. Fariq Abdul Hamid was on his first flight on a 777 as the first fully approved officer.
Hijacking: Chief investigators say they cannot rule out a "third" hijacking of the plane. However, no terrorist group claimed responsibility for the accident and there is no evidence that the aircraft was controlled "remotely". Furthermore, the report shows none of the passengers had experience piloting a plane
Fire or fumes: One theory is that the transport of lithium ion batteries may have caused a fire. These batteries, used in mobile phones and laptops, could be exploded or turned on. A tropical fruit booty that was out of season could have reacted with batteries, causing it to ignite or create dangerous fumes
L & # 39; hypoxia: The passengers and crew could have been rendered incapable by an event of unknown hypoxia – a lack of oxygen in the cabin. This theory holds that Mr. Shah would remain unconscious for hours.
