As Boeing struggles to get its grounded 737 Max back in the air - news of another hurdle.
The Federal Aviation Administration now says it'll be the sole issuer of airworthiness certificates for new 737 MAX jets. That means the agency must inspect and sign off on every jet before it's allowed to fly again. In the past, it had allowed Boeing and other plane manufacturers to oversee the process that ensures air worthiness.
The regulator also reiterated that it had not finished its review of the design changes and pilot training for the 737 MAX. Boeing's best-selling plane has been grounded worldwide since March following two fatal crashes.
Earlier this month, Boeing said it expected the FAA to give its blessing to the 737 MAX in mid-December. That prompted the agency to say it would not be guided by a calendar or a schedule.
A Boeing spokesman said it will follow the lead of the FAA and global regulators.
