Boeing is withdrawing an application for a safety exemption related to its 737 Max 7 aircraft as more details emerge on the cause of a near-disaster involving a 737 Max 9 plane used by Alaska Airlines.

While initial inspections of Alaska Airlines' fleet of Boeing 737 Max 9s turned up "many" loose bolts, a Wall Street Journal report yesterday said it now appears that "bolts needed to secure part of an Alaska Airlines jet that blew off in midair appear to have been missing when the plane left Boeing's factory."

"Boeing and other industry officials increasingly believe the plane maker's employees failed to put back the bolts when they reinstalled a 737 Max 9 [door plug] after opening or removing it during production, according to people familiar with the matter," the article said.
