Federal Aviation Administration officials Thursday were investigating a close call between a jet and a military helicopter at John Wayne Airport this week.
United Airlines Flight 589 was inbound to the airport in Santa Ana when a Sikorsky Black Hawk helicopter crossed its path about 8:40 p.m. Tuesday, according to FAA spokesman Ian Gregor.
FAA officials are investigating, “including whether a new measure to suspend the use of visual separation between airplanes and helicopters was applied,” Gregor said.
