New York (CNN) -- A US Airways plane touched down without landing gear at Newark Liberty International Airport in New Jersey early Saturday morning.
The plane was carrying 31 passengers and three crew members. U.S. Airways spokesman Davien Anderson told CNN that no injuries were reported.
US Express Flight 4560, operated by Piedmont Airlines, took off from Philadelphia around 11 p.m. Friday night. The plane reported a landing gear issue upon approach to Newark and stuck with a holding pattern before landing on its belly around 1 a.m. Saturday morning, an hour after it was scheduled to arrive. Upon landing, passengers and crew members were evacuated. They were transported to the terminal where they gathered their luggage and departed the airport, Anderson said.
An investigation into the matter is ongoing. US Airways is fully cooperating with the National Transportation Safety Board, Anderson said.
