Planes clip wings in ground collision at Phoenix airport

PHOENIX (AP) — Two passenger jets clipped their wingtips in a minor ground collision close to a Phoenix Sky Harbor International Airport terminal.

The Federal Aviation Administration said Friday it is investigating the collision, but National Transportation Safety Agency spokesman Terry Williams said that agency isn't investigating because damage was "very, very limited."

A departing Frontier Airlines flight bound for Denver was pushing back from its Terminal 3 gate when it collided with a taxiing Southwest Airlines flight arriving from Oklahoma City, the Phoenix Fire Department said.

The Southwest plane had a very minor leak in a wing fuel tank, Fire Department spokesman Rob McDade said.
