BEIJING—One month after a China Eastern passenger jet crashed mid-flight, killing all 132 people on board, investigators say they have not determined a cause.

A report issued Wednesday by the Civil Aviation Administration of China said no abnormalities had been found in the plane, its crew, or external elements such as bad weather.
