(AP) – Federal officials are investigating an incident in which a private plane was told to abort its landing and narrowly avoided crashing into a Southwest Airlines jet that was using the same runway to take off in the latest in a series of recent close calls between planes.

Jennifer Homendy, chair of the National Transportation Safety Board, told CNN on Monday that the business jet came “within 100 feet” of hitting the airliner.

The NTSB and the Federal Aviation Administration are investigating the incident, which happened Friday at San Diego International Airport.

The private jet was able to pull up and circle before landing safely.

The airport’s automated system for tracking planes and vehicles on the ground alerted the controller to the potential conflict, the FAA said.

The FAA and National Transportation Safety Board, which tweeted that it too was looking into the San Diego incident, ave investigated more than a half-dozen close calls at airports around the country this year. The surge led the FAA to hold a “safety summit” in March.

Federal officials are also investigating two other recent incidents.

They are looking into the crash of a Soviet-built fighter jet during an air show in Michigan on Sunday; the pilot and another person on board ejected and avoided serious injury, officials said.

Investigators are also looking into what caused a possible loss of cabin pressure on an American Airlines flight over Florida on Thursday. Oxygen masks dropped and the plane descended more than 15,000 feet three minutes before landing safely in Gainesville, Florida, the FAA said. Pilots usually try to fly lower where the air is richer in oxygen if they believe there has been a loss of cabin pressure.
