A United Boeing 777-200, registration N779UA performing flight UA-328 from Denver,CO to Honolulu,HI (USA) with 354 people on board, departed Denver's runway 25. While the aircraft was in the initial climb tower called operations vehicles telling them there was an active fire at runway 25 near taxiway B4 after a Boeing 777 had a bird strike during the takeoff run about 6200 feet/1890 meters down the runway. In the meantime, upon contacting departure, the crew declared Mayday reporting an engine (PW4077) failure on takeoff. The aircraft stopped the climb at 10,000 feet (about 5000 feet AGL) and entered a hold to work the checklists shutting the right hand engine down and dump fuel until having 3 hours of fuel remaining. The fire engine assigned to the runway fire reported they had contained it to a small weed fire near taxiway B7, there was no debris around however a lot of fuel, no further assistance was needed. Other emergency vehicles in the meantime took their stand by positions at runway 16R awaiting the return of the B772. The fire engine at runway 25 reported there were a number of small fires extending west of taxiway B7 seeing smoke. The fire chief told the engine at runway 25 to be ready to join the aircraft at runway 16R and leave the grass fires any time should there be any issue with the aircraft, the engine reported however they had almost run out of water and needed to return to the station for a refill. After completing the fuel dump the aircraft positioned for an approach to runway 16R, emergency services requested the crew to stop on the runway. The engines assigned to the grass fires in the meantime reported they had now put out all fires up to taxiway B10. The aircraft landed safely on runway 16R and advised they could taxi to the gate if emergency services approved it, advising they had no fire indications in the cockpit and thought they only distributed debris out of the engine quering whether there had been any foreign objects found on the departure runway. Emergency services reported no smoke, no fires, nothing critical visible, all tyres inflated, all good. The aircraft taxied to the apron with emergency services in trail. Emergency services reported after arrival at the gate that it appeared the turbine had exited the outlet of the right hand engine.

On Jun 13th 2016 the FAA reported the aircraft experienced an engine malfunction and returned to Denver, the damage is being assessed.
