An equipment failure on a portion of Richmond International Airport's federally run instrument landing system failed last night, leading to a handful of flights being either canceled or diverted.
Airport spokesman Troy Bell this morning said it was difficult to determine exact numbers because airlines were not required to list specific reasons for cancelled or diverted flights, but it appeared four flights were canceled and one was diverted as a result of the problem.
Operations at the airport had returned to normal by this morning, Bell said.
Federal Aviation Administration officials did not immediately respond this morning to repeated requests for information.
Bell said the problem appeared to have been traced to a localizer, a piece of equipment that is a component of the FAA-maintained instrument landing system at the airport. The equipment failed Thursday some time after 8 p.m., and by 9 p.m., with weather conditions deteriorating due to foggy conditions, the decision was made to cancel or divert flights.
