Alaska Airlines will start resuming service of its Boeing 737 MAX 9 fleet late Friday, three weeks after an emergency landing prompted sweeping inspections of the aircraft, the company said on its website. The first trip will be flight 1146 from Seattle to San Diego, leaving at 2240 GMT and arriving at 0105 GMT on Saturday. The voyage comes after the Federal Aviation Administration on Wednesday cleared the MAX 9 to resume service following stepped-up inspections. Alaska Airlines said it expects inspections on its fleet of 65 MAX 9 planes to be completed by the end of next week, allowing for a resumption of its schedule. “Each of our 737-9 MAX will return to service only after the rigorous inspections are completed and each plane is deemed airworthy according to FAA requirements,” the company said. “The individual inspections are expected to take up to 12 hours per aircraft.” The FAA grounded 171 MAX 9 planes with a similar configuration to the one in the January 5 incident, in which a door plug blew out mid-flight. While nobody was seriously injured in the incident, inspectors have said the episode could have been catastrophic. The grounding resulted in 3,000 Alaska Airlines flight cancellations in January. The company said on Thursday that it expects a $150 million hit from the grounding.
