A US Airways jet briefly caught fire on Monday evening at its gate in the Phoenix airport. No injuries were reported.
The fire started at 10:55 p.m. ET in the plane’s auxiliary power unit – a small motor that provides power to the aircraft when the engines are not running.
Two pilots and three flights attendants were on board when they noticed a problem to the rear. The Phoenix Fire Department was then called to investigate a fuel leak, Phoenix Fire Department public information officer Jonathan Jacobs told NBC News.
Fire crews found a small blaze at the back of the jet and quickly sprayed the plane with foam.
There were no passengers on board the Vancouver, Canada-bound jet at the time, Phoenix Sky Harbor International Airport spokeswoman Kris Commerford told The Associated Press. The plane had arrived earlier in the day from California.
The flight's 101 passengers were put on a different US Airways flight, scheduled to leave two hours later.
