Boeing aims for key 737 MAX certification flight in late June: Sources

Boeing Co is aiming to conduct a key certification test flight on its grounded 737 MAX jet in late June, two people briefed on the matter said on Wednesday.

The 737 MAX has been grounded since March 2019 after two fatal crashes killed 346 people. Boeing told airlines it hopes to conduct the flight in late June, the sources said.

Boeing did not comment on the certification flight timing, but said late Wednesday it had won approval from the Federal Aviation Administration for a service bulletin that details the modifications required for 737 MAX wiring.

“Boeing has already begun modifying airplanes that have not yet been delivered and is coordinating modification efforts with the airlines,” the company said. “New airplanes being built will include this update,” it added.
