US airlines expect Boeing 737 MAX jets need up to 150 hours of work before flying again

Once regulators approve Boeing's grounded 737 MAX jets for flight, each aircraft will likely require between 100 and 150 hours of preparation before flying, officials from the 3 US airlines that operate the MAX told Reuters. The estimate is the first indication of the time needed to bring the jets out of storage following a worldwide grounding in March. The preparations were discussed at a meeting between Boeing and MAX customers in Miami earlier this week, and include a list of items ranging from fluid changes and engine checks to uploading new 737 MAX software. The estimated time frame does not include pilot training, they said. Boeing said the company's maintenance and engineering teams have been working with customers to determine how to efficiently stage work once regulators approve the fleet's return to service. <br/>
