Civil Aviation Alliance: According to Lianhe Zaobao, when United Airlines inspected the grounded Boeing 737 MAX 9 aircraft, it found that several aircraft had loose bolts.
Last week, an emergency hatch of an Alaska Airlines Boeing 737 MAX 9 plane suddenly fell off after takeoff. The Federal Aviation Administration (FAA) ordered the temporary grounding of Boeing 737 MAX 9 aircraft operated by American Airlines or operated within the United States to conduct safety checks.
Reuters reported on Monday (January 8), citing aircurrent, a flight industry publication, that United Airlines found problems with bolts on at least five other parts of the fuselage deck when it inspected the Boeing 737 MAX 9 aircraft.
The Federal Aviation Administration and Boeing declined to comment on the report.
Earlier Monday, Boeing issued detailed instructions to airlines on how to inspect Boeing 737 MAX 9 aircraft, which will allow airlines to complete inspections or certify that their inspections comply with FAA directives.
The Federal Aviation Administration issued a statement on the same day, saying: "The Boeing 737 MAX 9 aircraft will continue to be grounded until the operator completes more rigorous inspections, including left and right door exit plugs, door assemblies and fasteners." It added: "Before any aircraft can be put back into service, operators must also complete the requirements for corrective actions based on the inspection results." ”
On the evening of January 5, shortly after a new Alaska Airlines Boeing 737 MAX 9 took off from Portland, Oregon, an escape door in the left rear compartment suddenly fell off, forcing the plane to make an emergency turn, but fortunately the 174 passengers and six crew members on board were unharmed.
