Right side engine blew apart on takeoff. New inspection procedures coming. United has grounded 24 of theirs.

Amazing they landed safe and no one was injured.

FOD foriegn object debris. Sucking up something as small as a bb can shell out a jet engine. Another failure can be the carbon seals around bearing. A shaft runs through the center of them. They run at such high rpm you must wear special gloves to install them. oil from your hands can cause a failure. The bearing seals are made of carbon to withstand heat and are very fragile. two weak spots in all jets or turbofans. I doubt it is a design failure.

Can you imagine after a couple years of inactivity, grounded air craft and rusty pilots? (JK)

Hard to beat the 747 with two engines hanging off each wing!!

Hard to beat well trained pilots!!!!

Absolutely! First rule of flying - Aviate

I have a friend who flies them around the world three times a week. He thinks they are a fine piece of equipment

Anyone what brand engine - Rolls-Royce, GE, Pratt & Whitney? I think RR on 777-300. Don't know about 777-200.

P&W

Just read Boeing grounded around 120 of theirs.

machines fail at times. i think it was just one of those times.

The original 777 with a maximum takeoff weight (MTOW) of 545,000–660,000 lb (247–299 t) was produced in two fuselage lengths: the initial -200 was followed by the extended-range 777-200ER in 1997; and the 33.25 ft (10.13 m) longer 777-300 in 1998. Those 777 Classics were powered by 77,200–98,000 lbf (343–436 kN) General Electric GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines.[8] The longer-range 777-300ER, with a MTOW of 766,000–775,000 lb (347–352 t), entered service in 2004, the ultra long-range 777-200LR in 2006, and the 777F freighter in 2009. These long haul variants use 110,000–115,300 lbf (489–513 kN) GE90 engines and have extended raked wingtips. In November 2013, Boeing announced the 777X development with the -8 and -9 variants, scheduled to enter service by 2020. The 777X has composite wings with folding wingtips and General Electric GE9X engines.

excess of 50,000 hp.... unbelievable power.... hard to imagine it can fly one engine out....... i bet it took some serious rudder and aileron to keep her level....... hats off to the pilots !! good job !

Absolutely correct. This makes 2 in the last 2 months.

The GE9X engine for the Boeing 777X has been recognized by the Guinness Book of World Records as the the most powerful commercial aircraft jet engine (test performance) after reaching 134,300 lbs of thrust.Jul 24, 2019

i thought i read somewhere that this plane had a p+w......... might wanna hang onto your hat if ya got near the fan!!

im pretty sure they are fly by wire capable.... be interesting if the computer took over and flew one engine out.... we all criticise tecnology...when it fails but they have some amazing technology i love to fly

Boeing’s recommendation followed action by regulators in the U.S. and Japan aimed at the Pratt & Whitney engines found on 128 of its 777s. The United Airlines Holdings Inc. flight Saturday was the third failure involving that model plane with those engines in recent years.

Safety investigators in the U.S. are trying to determine why the engine failed shortly after the Honolulu-bound plane took off, forcing it to return to Denver International Airport and leaving a trail of debris scattered over a nearby town.

United, the only airline in the U.S. that uses that engine type, said earlier Sunday evening that it had taken two dozen planes out of service.

In 2000, over 2,000 PW4000 engines had accumulated over 40 million hours of service with 75 operators.[1] In 30 years between June 1987 and 2017, more than 2,500 engines have been delivered, logging more than 135 million flight hours.[2]

Danny are you an A&P?

P & W 4000!

No dylan. air force jet engine mechanic a few years ago
