Air Pressure and Loose Bolts

Boeing, during inspections this week, found loose bolts on door plugs used with Boeing 737 Max 9 aircraft in the aftermath of a dramatic Alaska Airlines fuselage failure at 16,000 feet Friday during a flight with 177 passengers aboard. Alaska Airlines has 65 of the planes in its fleet. No one was seriously injured.

United Airlines described finding “installation issues” Monday as it inspects its fleet to make sure its 79 Boeing 737 Max 9 planes are safe to fly. Federal investigators also continue probes. The Federal Aviation Administration on Saturday grounded 171 of the planes worldwide.
