This little Device is responsible for the Crash of the Ethiopian plane

A screw-like device found in the wreckage of the Boeing 737 Max 8 that crashed on Sunday in Ethiopia indicates the plane was configured to dive, a piece of evidence that helped convince United States regulators to ground the model, a person familiar with the investigation said late on Thursday (March 14).

Federal Aviation Administration chief Daniel Elwell on Wednesday cited unspecified evidence found at the crash scene as part of the justification for the agency to reverse course and temporarily halt flights of Boeing’s best-selling aircraft.

Up until then, American regulators had held off as nation after nation grounded the plane.

The piece of evidence was a so-called jackscrew, used to set the trim that raises and lowers the plane’s nose, according to the person, who requested anonymity to discuss the inquiry.

A preliminary review of the device and how it was configured at the time of the crash indicated that it was set to push down the nose, according to the person, who wasn’t authorised to speak publicly about the investigation.

The jackscrew, combined with a newly obtained satellite flight track of the plane, convinced the FAA that there were similarities to the Oct 29 crash of the same Max model off the coast of Indonesia. In the earlier accident, a safety feature on the Boeing aircraft was repeatedly trying to put the plane into a dive as a result of a malfunction.
