A United Airlines jumbo jet flying 301 passengers to Honolulu was forced to return to New Zealand Monday with engine problems, the airline said.

The pilot shut down an engine while still climbing out of Auckland after he received indications it was not working properly, United spokesman Sean McNamara said.The pilot dumped some fuel and flew the Boeing 747 on the remaining three engines, landing back at Auckland 35 minutes after takeoff.

Last month nine passengers were sucked to their death when a United Airlines 747 flying the same route but in the opposite direction lost a cargo door and part of the fuselage was ripped away over the Pacific.

On Saturday a United Airlines 747 bound for Tokyo was forced to return to Manila after a fiberglass section of its right wing was ripped open.
