Boeing has been told by the US Federal Aviation Agency that it will be the sole issuer of airworthiness certificates for all new 737 MAX jets, according to a report by Reuters.
In a letter reportedly sent to Boeing, the FAA has said it "determined that the public interest and safety in air commerce require that the FAA retain authority to issue airworthiness certificates and export certificates of airworthiness for all 737 MAX airplanes."
Furthermore, the FAA said it will keep the authority it previously shared to issue certificates until it is confident that Boeing has "fully functional quality control and verification processes in place".
Boeing is standing firm that the aircraft will take to the skies again in the early part of 2020.
