WASHINGTON (Reuters) - Boeing CEO Dave Calhoun apologized and vowed the planemaker would follow government rules after the National Transportation Safety Board said the company provided non-public information about the 737 MAX mid-air panel blowout, the safety panel's top official said on Wednesday.

NTSB Chair Jennifer Homendy told Reuters Calhoun called her after the NTSB criticized Boeing on June 27 for violating its investigation rules. "He said they were revisiting with everybody what the rules are for NTSB investigations," Homendy said, calling it a "very good conversation."
