- The six last minutes of the flight were captured in the plane's cockpit voice recorder and data recorder
- Engineers who studied the flight path say the plane started giving conflicting Angle of Attack (AOA) data hardly a minute after take off
- Crew contacted the control tower where they requested to return and they were cleared
- The crew tried to correct the situation by engaging autopilot but the flight remained chaotic with abnormal movements
A recently released investigative report on the Ethiopian plane crash has revealed the six minutes of horror passengers and crew of the aircraft went through.
The preliminary findings contained in a 33 page document show that pilots of the plane tried all they could to avert a crash but to no success.
According to a report filed by the Standard on Monday, April 8, the Boeing 737 Max-8 kept flying in a nose down position and could not respond to all emergency procedures pilots executed.
Here is a detailed account of what happened between 8.37am and 8.44am on the dark morning of Sunday, March 10.
The control tower at Bole International Airport, in Addis Ababa gave crew nod to take off.
The 737 Max-8 took off with accurate angle of attack (AOA) indications.
While climbing to the required cruising altitude, the captain's AOA indicator started indicating a conflicting angle from that of the first officer.
The captain engaged the auto pilot hoping that it troubleshoots the differences in AOA.
An auto pilot warning was heard.
A second autopilot warning is recorded as captured by cockpit voice recorder.
The first officer is instructed by the captain to contact radar.
The plane's left auto pilot is engaged for at least 33 seconds and flaps retracted (flaps are used to generate more lift during lower speed).
Autopilot is disengaged and plane experiences amplitude roll oscillations and at the same time literal acceleration.
Pilots set the plane to fly at 32,000 feet and the speed at 440.78 kph.
The captain instructed first officer to set the flaps up.
Heading started to change from 072 degrees that was set to 197 degrees while the pilot kept insisting to first officer to maintain runway heading.
Autopilot was turned off.
The plane recorded a nose down motion for about nine seconds causing a slight drop in altitude.
Terrain senors informed pilots that they were flying close to the ground.
Captain told the officers to trim up with him.
First officer shouted "stab trim cut-out" two times.
The captain acknowledged and first officer responded stab "trim cut-out."
Captain directed his first officer to pull up since the plane was flying too low.
The assistant agreed to pull up.
Pilots selected cruising altitude to 14,000 ft from 32,000 ft
Captain told first officer to pitch up with him (lifting the plane's nose up).
An over speeding warning signal was recorded from the left side of the cockpit and remained on till end of recording.
Plane went back to a nose dive position and could not respond to corrections applied by pilots.
The speed climbed from 440.78 kph to 848.27 kph according to indications from the left instruments in the cockpit.
However, instruments on the right side indicated flight speed was 926 kph.
The brand new plane tumbled from the Ethiopian skies crashing in an open field near Bishoftu in a ball of fire and ended lives of all 157 on board.
