A preliminary report into the EgyptAir crash will be presented in one month, it’s reported.

The head of the Egyptian investigation team was quoted as saying it will take four weeks for the information to be compiled, Egypt’s state-owned Al-Ahram newspaper reported.

Ayman al-Moqadem, the head of Egypt’s Air Accidents Investigation department, said the report “will be published in one month ... and will include all the information gathered by the date of its publication”.

Egyptian officials did not observe the doomed EgyptAir flight swerve and change direction before it disappeared, an Egyptian aviation official has said.

Greece's defence minister said the plane turned 90 degrees then 360-degrees before plummeting into the sea.

Neither EgyptAir nor the Ministry of Civil Aviation have commented on the plane's final movements.

The reason for the discrepancy between the Greek and the Egyptian aviation official's accounts of the crash is not clear.
