WASHINGTON/PARIS/ADDIS ABABA – French investigators on Friday will begin analyzing data from the black boxes of the Boeing 737 Max plane that crashed after takeoff from Addis Ababa killing 157 people, the second such calamity involving the aircraft since October.

Experts will be looking for any links between Sunday’s Ethiopian Airlines crash and the October crash of a 737 Max operated by Lion Air in Indonesia that killed 189 people. The U.S. Federal Aviation Administration grounded all Boeing MAX jets in service because of similarities between the two crashes.

Boeing said it had paused deliveries of its fastest-selling 737 MAX aircraft built at its factory near Seattle, but continues to produce the single-aisle version of the jet at full speed while dealing with the worldwide fleet’s grounding.

Possible links between the accidents have rocked the aviation industry, scared passengers, and left the world’s biggest planemaker scrambling to prove the safety of a money-spinning model intended to be the standard for decades.
