FAA investigating close call between United jet, Army helicopter

WASHINGTON, March 26 (Reuters) - The Federal Aviation Administration said on Thursday it was investigating a close call between a United Airlines jet and an Army Black Hawk helicopter in California.

The FAA said the United Boeing 737 jet on Tuesday at 8:40 p.m. was on approach to John Wayne Airport in Orange County, California, and a Black Hawk crossed in front of the plane. Flightradar24, a flight tracking site, said the aircraft were 525 feet apart vertically.

The FAA is also investigating whether the incident violated its new policy that bars visual separation for helicopters near major airports.
