Dear friends and followers, welcome back to my channel!
On the 20th of February 2021, a United Boeing 777-200, registration N772UA performing flight UA-328 from Denver,CO to Honolulu,HI (USA) with 231 passengers and 10 crew, was in the initial climb out of Denver's runway 25 when the right hand engine's (PW4077) inlet separated associated with the failure of the engine. The crew declared Mayday reporting an engine failure. The aircraft stopped the climb at about 13000 feet, the crew requested to return to Denver after running the checklists. ATC offered any runway, they would make it happen. The aircraft returned to Denver for a safe landing on runway 26 about 23 minutes after departure. The aircraft stopped on the runway for a check by emergency services. Emergency services advised of an active fire within the right hand engine and extinguished the fire a few minutes later. The aircraft was subsequently towed off the runway to a remote parking stand, where passengers disembarked and were bussed to the terminal. There were no injuries.
The engine inlet fell into the neighbourhood of Broomfield,CO, located about 16nm west of Denver near 13th and Elmwood Street, the debris also struck through the roof of an adjacent house.
Broomfield police reported that although debris impacted the neighbourhood and damaged a number of homes, there were no injuries on the ground. The debris field expands over a nautical mile.
Ground observers reported hearing the sound of an explosion like bang, smoke and saw the debris falling down. The aircraft continued flying.
Watch the video to learn more about what happened!
Thank you very much for your time! I hope you enjoy this video!
Wishing you all the best!
Your "Captain" Joe

    Very good video Cap. Joe! Appreciate the time and effort that go into these reports. One thing I’d like to point out, is that as far as we can tell, it was a contained failure. The kevlar shroud did not fail, simply the nacelle, which is a part of the airframe, came off. Agent JayZ, a turbine expert, had a good explanation on this event. I am unaware if the NTSB has listed this as an uncontained failure, I don’t believe they have 😉

    Why was there no mention of fuel dump? You can't land a fully loaded aircraft with fuel to Hawaii without it breaking apart. Did they just not want to call attention to thousands of gallons of jet fuel atomizing onto cars, homes, people and animals?

    Hi, I respectfully disagree with two of your points beginning at 3:40 and 8:00. I come from an engineering background, and have been employed as a pilot for a major airline for more than a decade. I am currently qualified on the Boeing 787. My opinion highlights why it is premature to comment or speculate on aviation incidents prior to facts and final reports are published. At 3:40 you say that it’s likely that while transitioning to a cruise climb that the power increase caused the fan blade to fail. There would not normally have been any major power changes at that point of the flight. The aircraft would have accelerated from about 250 knots, but that is accomplished by lowering the nose and allowing the aircraft to accelerate with the same thrust setting. I acknowledge that the trust setting isn’t actually constant, and that the FADEC is programmed to make constant, small changes to climb thrust due to environmental conditions. Many engine failures do occur with large thrust changes, but this usually occurs at the beginning of the takeoff roll, thrust reduction from takeoff to climb thrust, and application of go-around thrust. The video from @VASAviation, linked below, outlines the radar tape and communications of the affected flight. From 8000 feet to approximately 12,000 feet, there is a constant acceleration from 260 knots to 320 knots with no apparent level offs. Therefore, there is no reason to believe any significant thrust changes have occurred. You then go on to explain, incorrectly, what an uncontained engine event/failure is. Uncontained engine failure is when an engine fan blade fails and penetrates the containment ring of the engine case, not the engine cowling. The cowling is the outer covering of the engine that we can see. It contains the ancillary systems of the engine. On February 22nd, the NTSB considers this event to be contained. For an example of an uncontained engine failure, see example of Qantas 32, links below to the ATSB report and Wikipedia page. At 8:00, you state that the extinguishing agent is discharged into the turbine. This is also not correct. The extinguisher is discharged into the engine compartment. In the case of UA328, this would have been ineffective because the engine cowling is required to contain the agent within the compartment to be effective. Aircraft engine fire systems are not designed to control fires within the combustion sections of the actual engine. Also, the visible fire is not likely fuel fed, as the NTSB determined that the firewall fuel shut-off valve (spar valve) was found in the commanded, off position, post flight. I’m not sure if the HYD PRESS, L checklist would have needed to be accomplished. It is possible that the L hydraulic demand pump (electric) automatically took over pumping duties. On the 787, it is not routine to need to complete hydraulic checklists following engine failures, fires and severe damage events in simulator training. It is critical that we as pilots do not speculate on causal factors prior to known facts being published. The NTSB and other governmental investigative agencies offer only factual evidence in their updates and do not assign blame. Their mandate is to determine cause and prevent further occurrences. By speculating, you are potentially propagating inaccuracies that only fuel the spread of mis-information among the travelling public, who are mostly laypeople. Had you waited one extra day to publish this video, you could have had valuable information with which to produce a more accurate description of the incident. Instead, you hastily posted this with the intention of gaining views and being the first to report the news. www.NTSB.gov: NTSB Issues Investigative Update for United Airlines Flight 328 Engine Failure Event www.avherald.com: Incident: United B772 at Denver on Feb 20th 2021, engine inlet separates from engine, engine fire VASAviation: bgvideo.info/manage/video/d2dk4JqdtJaT1Jw.html www.atsb.gov.au: Investigation: AO-2010-089 - In-flight uncontained engine failure Airbus A380-842, VH-OQA, overhead Batam Island, Indonesia, 4 November 2010 www.wikipedia.org: en.wikipedia.org/wiki/Qantas_Flight_32?wprov=sfti1

I lived in Denver for more than a decade and the airport... the newest one........is far away from the city. Is it usual for aircraft to be this old. I flew from Denver once to Hawaii, it was not too long after the top was peeled off one and sucked out a flight attendant. and our flight was in a thunderstorm trying to land. That plane shook so bad, scariest flight I have ever been on! Everyone I want those pilots on my next plane ride..... they were awesome!!!!

    They made a tight left u turn and could have lined up for the runway they took off from. That would have been the quickest route to landing. My question is why would they buy time in the air by passing up that runway and circling in from the opposite direction, just to complete the checklists, when they could have set down sooner? Should a crippled air craft try to stay in the air to complete checklists if they are inline for a much quicker landing? That seems like they are taking a much bigger chance of crashing by staying up! Please clear up this question of landing immediately or staying aloft to complete checklists! I feel they should have landed sooner on the same runway without completing checklists since it was offered to them. Thanks. Great video. Jpol.
