Cause of air Egypt 737max crash announced or caused by bird impact

According to foreign media reports, the air crash or caused by bird impact. They said that after the plane took off, the 737max8 was hit by birds or other foreign bodies, causing sensor damage, and then the nose was forced to push down, causing the air crash.

ABC quoted two sources familiar with the investigation of the air crash in Egypt as saying that the 737max8 plane crashed in Egypt last month was hit by birds or other foreign bodies after taking off, resulting in the damage of an angle of attack sensor on the plane. The automatic anti stall system (MCAS) on the plane received the wrong reading and forced the nose of the plane to push down, which eventually caused the air crash.

The source also said that as MCAs pushed the nose down, the pilot did not attempt to lift the nose up through electronic equipment before cutting off the power supply of the horizontal stabilizer at the tail of the aircraft according to the emergency procedures formulated by Boeing. One of the sources also told ABC that the pilots tried to lift the aircraft's nose with the trim tab, and soon they regained the power of the horizontal stabilizer. However, with the recovery of power, MCAs was activated again, which made the pilot unable to control the aircraft.
