Boeing said Thursday it would make multiple changes to the beleaguered 737 Max aircraft following the release of the preliminary investigation report of the Ethiopian Airlines Flight 302 crash.

The report, issued by the Ethiopian Accident Investigation Bureau, found that data from the flight recorder indicated that the aircraft had received erroneous information from the angle of attack sensor that in turn activated the Maneuvering Characteristics Augmentation System, or MCAS, shortly before the crash.  This was the same as in the Lion Air Flight 610 disaster.

“We will carefully review the AIB’s preliminary report, and will take any and all additional steps necessary to enhance the safety of our aircraft,” Boeing said in a statement.

Immediate changes include a software update for MCAS that adds additional layers of protection and requires MCAS to read information about the aircraft’s nose angle from multiple sensors instead of just one.   The changes are intended, Boeing said, to “ensure unintended MCAS activation would not occur again.”

MCAS automatically takes over flight control when an aircraft’s nose suddenly rises in a way that could lead to stalling.

Boeing is also creating a comprehensive pilot training and supplementary education program for 737 Max pilots.

The aircraft manufacturer also sent a message to those who lost someone in the incident.

“I’d like to reiterate our deepest sympathies are with the families and loved ones of those who lost their lives in the accident,” said Kevin McAllister, the president of Boeing’s commercial airplane unit.
