story.lead_photo.caption Boeing 737 Max jets, like these parked Thursday at Sky Harbor International Airport in Phoenix, will be grounded until updated flight control software is installed, officials said.

Ethiopia has sent black boxes from a crashed Boeing 737 jet to France for decoding after refusing to hand them to U.S. authorities that had kept the Max model flying after most other regulators grounded it.

The flight-data and cockpit-voice recorders arrived at France's air-accident investigator, with coordination meetings underway and technical work set to start today. The investigative bureau said it will download data but hasn't been asked to analyze it.

Ethiopian Airlines, which operated the crashed jet, says the decision to send the black boxes to a European agency was a strategic one after the Federal Aviation Administration was left isolated in arguing that the Max should continue flying. The U.S. regulator finally grounded the model Wednesday amid mounting concern about similarities between the African disaster and a crash in Indonesia, in which a computer system took control of a flight.

Germany's Federal Bureau of Aircraft Accident Investigation earlier declined to work on the boxes, saying it wasn't technically possible. France has a direct link to the crash, which killed 157, since the Max's engines are made by the CFM International venture of General Electric and Paris-based Safran.

The choice of France's investigator for the decoding of the recorders still represents a snub for U.S. regulators used to taking a leading role in probes of Boeing planes. The National Transportation Safety Board will still have a role given that the 737 is made in Seattle, and plans to send three investigators to France to help its investigative bureau with the downloading and analysis, according to a statement.

The National Transportation Safety Board also emphasized its own "expertise in recorders, flight crew operations and human factors," and stressed that the Ethiopian Aircraft Accident Investigations Bureau remains in charge of the investigation. The Washington-based agency already has officials in Addis Ababa, assisted by advisers from the FAA, Boeing and GE/Safran.

France's investigative bureau made headlines in 2011 when it took just weeks to recover the full contents of data and voice recorders from an Air France plane after the devices had spent two years in 12,800 feet of seawater. The breakthrough helped explain the worst accident in the carrier's history.

French President Emmanuel Macron has meanwhile held discussions with Ethiopian Prime Minister Abiy Ahmed about a new contract for Toulouse-based Airbus as part of a renewal of the Ethiopian Airlines fleet, a French official said Thursday.

Though the African carrier already operates the European plane-maker's A350 wide-body, all of its other jets are Boeings, including 787 Dreamliners for which it was one of the first global customers, and a variety of 737s.

Macron will also discuss a major Airbus order during his Chinese counterpart Xi Jinping's state visit to France later this month, the official said. China has 20 percent of all delivered Max jets and was the first major authority to ground the model after Sunday's crash.

The Asian nation will itself be looking to benefit from the 737's travails by attracting more sales for the Comac C919, which the company says has more than 800 orders worldwide.

Boeing's $600 billion-plus backlog for the 737 Max is also looking shaky as several big customers reconsider their purchases, among them VietJet Aviation JSC, which doubled its order to about $25 billion last month, and Lion Air, operator of the plane in the Indonesia crash, which plans to drop a $22 billion deal, according to a person with knowledge of the plan.

Indonesia will send two officials to Addis Ababa as observers of the investigation into the crash, and will share data and insights from its own probe into the loss of Lion Air flight 610 in October, according to Soerjanto Tjahjono, chairman of the country's National Transportation Safety Committee.

The Lion Air Max experienced more than two dozen sharp dips shortly after takeoff, with a preliminary report suggesting the jet was automatically commanded to dive because the software thought it was in danger of losing lift after a sensor malfunction.

A Boeing 737 Max 8 plane sits parked Thursday at King County International Airport, often called Boeing Field, in Seattle. Boeing Co. officials say they support grounding the Max 8 and Max 9 aircraft.
