The Federal Aviation Administration's tougher oversight of Boeing will continue indefinitely, the agency's outgoing head said on Friday, nearly a year after a door panel missing four key bolts flew off a new Alaska Airlines 737 MAX 9 in mid-air.

Boeing (NYSE:BA) said Friday it is conducting more surprise inspections at its factories, as part of a broader plan to confront a manufacturing quality crisis that has forced the company to slow production and raised scrutiny from federal regulators.

The jet manufacturer outlines more than a dozen steps it has taken in recent months to address concerns about production issues.

A year after a panel blew out of a Boeing 737 Max during flight, the nation’s top aviation regulator says the company needs to change its culture and put safety above profits.

Boeing Co. is kicking off the new year with a renewed push to improve safety and quality in manufacturing to prevent the issue that led to a jet-panel blowout on an Alaska Air flight last January.
