FAA: Boeing failed to improve safety measures. Boeing has come under pressure from U.S.

regulators, airlines and members of Congress over aircraft quality control issues. In a statement, Boeing said it supported the group's work and acknowledged that while the company has taken "important steps" to improve its safety culture, more work remains to be done. The Federal Aviation Administration said in a statement that it would take appropriate action based on the report's recommendations. "We will continue to hold Boeing to the highest safety standards and will work to ensure the company fully implements these recommendations," the FAA said.
