No Sign Of EgyptAir Technical Problems Before Takeoff

May 24, 2016

The EgyptAir jet that disappeared last week did not show technical problems before taking off from Paris, people within the Egyptian investigation committee said.

The people said the plane did not make contact with Egyptian air traffic control, but Egyptian air traffic controllers were able to see it on radar on a border area between Egyptian and Greek airspace known as KUMBI, 260 nautical miles from Cairo.

Speaking to Reuters on condition of anonymity, the people said the plane disappeared without swerving off radar screens within a minute of it entering Egyptian airspace. Air traffic controllers from Greece and Egypt have given differing accounts of the plane's final moments.

Egypt's state-owned newspaper Al-Ahram reported on Tuesday that the plane had shown no technical problems before taking off, citing an Aircraft Technical Log signed by its pilot before takeoff.

Al-Ahram published a scan of the technical log on its website. The paper said EgyptAir flight MS804 transmitted 11 "electronic messages" starting at 22:09 London time on May 18, about 3 1/2 hours before disappearing from radar screens with 66 passengers and crew on board.

The first two messages indicated the engines were functional. The third message came at 01:26 London time on May 19 and showed a rise in the temperature of the co-pilot's window. The plane kept transmitting messages for the next three minutes before disappearing, Al-Ahram said.

The head of Egypt's forensics authority dismissed as premature a suggestion that the small size of the body parts retrieved since the Airbus A320 crashed indicated there had been an explosion on board.

Investigators are looking for clues in the human remains and debris recovered from the Mediterranean Sea.

The plane and its flight recorders, which could explain what brought down the Paris-to-Cairo flight, have not been located.

An Egyptian forensics official said 23 bags of body parts had been collected, the largest no bigger than the palm of a hand. Speaking on condition of anonymity, the official said their size pointed to an explosion, although no trace of explosives had been detected.

But Hisham Abdelhamid, head of Egypt's forensics authority, said the assessment was "mere assumptions" and that it was too early to draw conclusions.

SCRAPS OF DATA

Investigators do have a few scraps of data in the form of fault messages sent by the aircraft in the last minutes of flight, logging smoke alarms in the forward lavatory and an electronics bay, but they are brief.

"The difficulty is to connect these bits of information," said John Cox, executive of Washington-based Safety Operating Systems who co-authored a report on smoke and fire risks by Britain's Royal Aeronautical Society.

There are too few messages to fit a typical fire, which would normally trigger a cascade of error reports as multiple systems failed, he said, and too many of them to tie in neatly with a single significant explosion.

Investigators also need to understand why, for example, there was no message indicating the autopilot had cut off, progressively handing control back to the pilots as systems failed and computers became unsure what to do.

The Frenchman who headed a three-year investigation into the 2009 loss of an Air France jet in the Atlantic said the data published so far appeared insufficient for any conclusion.

Egypt has deployed a robot submarine and France has sent a search ship to help hunt for the data recorders, but it is not clear whether either of them can detect signals emitted by the recorders, lying in waters possibly 3,000 m (10,000 feet) deep. The signal emitters have a battery life of 30 days.

LAST MOMENTS

Five days after the plane disappeared from radar screens, air traffic controllers from Greece and Egypt were still giving differing accounts of its last moments.

In Greece, two officials stood by earlier statements that Greek radar had picked up sharp swings in the jet's trajectory - 90 degrees left, then 360 degrees right - as it dropped from cruising altitude to 15,000 feet before vanishing.

Ehab Mohieldin Azmi, head of Egypt's air navigation services, said Egyptian officials had seen no sign of the plane making sharp turns, and that it had been visible at 37,000 feet until it disappeared.

Relatives of the victims were giving DNA samples at a hotel near Cairo Airport on Tuesday to help identify the body parts, their grief mixed with frustration.

Amjad Haqi, an Iraqi man whose mother Najla was flying back from medical treatment in France, said the families were being kept in the dark and had not been formally told that any body parts had been recovered.

"All they are concerned about is to find the black box and the debris of the plane. That's their problem, not mine," he said. "And then they come and talk to us about insurance and compensation. I don't care about compensation, all I care about is to find my mother and bury her."
