A Boeing 737-800 plane flying from San Francisco was found to have a missing panel after landing safely at its scheduled destination in southern Oregon, said the US Federal Aviation Administration on Friday.
The plane of United Airlines, a Flight 433, "landed safely at Medford Airport in Oregon around 11:30am local time on Friday, March 15. A post landing airline inspection revealed a missing panel," the FAA, Boeing's primary regulator, said in a statement.
"The FAA will investigate," it added.
Boeing has encountered many quality and safety concerns for years with its aircraft, resulting in an extended grounding of certain planes and delivery suspensions.
