The Federal Aviation Administration (FAA) said it is investigating a recent near-midair collision of flights that were approaching Phoenix Sky Harbor International Airport. A Delta Air Lines flight, as well as a United Airlines flight “landed safely” following “a loss of required separation” while both en route to the Phoenix airport, according to a Saturday statement from the FAA. The statement said the crews for the flights got “onboard alerts” about their aircraft being close and that “corrective instructions” aimed at the crews came from air traffic control. The agency is investigating the incident, which occurred around 11 a.m. local time over the weekend. In their own statement, United said as one of their flights “was preparing to land at Phoenix on Saturday, its pilots received an automated flight deck warning to change their altitude.” “The pilots acted immediately and landed safely,” United added. "We’re working with the FAA on its investigation." A spokesperson for Delta said in a statement to The Hill that with "nothing" being "more important than safety, Delta flight crews extensively train to handle uncommon scenarios such as this and followed the resolution advisory as directed." Last Wednesday, a different United flight was clipped by another jet while taxiing at Chicago O’Hare International Airport, the FAA said at the time. According to an emailed statement from an FAA spokesperson to The Hill from last week, an American Airlines Boeing 737-800 jet “struck the tail of” a United Airlines 787 jet while taxiing last Wednesday on separate taxiways at Chicago O’Hare International Airport at about 10:00 a.m. CST.
