Boeing expects aviation regulators to sign off on its fixes for the 737 MAX and a revised training regime early in the fourth quarter, but given previous delays and new technical issues that have arisen over the past few months, some industry watchers think the plane’s return to service could slip further. Southwest Airlines has taken the 737 MAX off its flight schedule till January 5; Air Canada has scrubbed the plane through January 8.
A Southwest spokesman said that once the U.S. Federal Aviation Administration declares the model airworthy, the airline expects it will take 120 hours of work on each plane to get them ready to fly again, and 30 to 60 days for the airline’s whole fleet.
One giant task: cleaning the planes. Dust can collect inside planes stored in the desert if the doors are vented, requiring a thorough vacuuming, says Zemanovic, and if the storage facility doesn't have a concrete wash pad with drains to properly dispose of large amounts of soapy water, workers may have no choice but to wipe down the plane by hand, a laborious process that he says could require a “couple hundred” man hours. Two necessities for the job: 27-foot high work platforms and a mammoth supply of cleaning wipes.
