According to CCTV news, on January 24th local time, the Federal Aviation Administration of the United States approved a thorough inspection and maintenance procedure for each grounded Boeing 737 MAX 9 aircraft, and only after successful completion can it be eligible to resume operation.
It is reported that after a thorough review of data from 40 grounded aircraft, the Federal Aviation Administration of the United States approved this detailed inspection and maintenance plan and convened a corrective action review committee composed of safety experts to review and approve inspection and maintenance procedures. Federal Aviation Administration Director Mike Whittaker stated that the agency will not agree to Boeing's request to expand production or approve the addition of the 737 MAX production line until the quality control issues identified during inspections and maintenance are resolved.
