United owes that guy a truck.
An expensive truck.

Is the max landing weight the same as Max takeoff weight or sound they have dumped fuel. It didn’t seem like they were airborne long enough to burn it off.

Doesn’t matter. In an actual emergency you can land at any weight. It will trigger overweight landing inspections and whatnot but that is the least of your concerns. In that scenario you get it on the deck as soon as you safely can.

Interesting listening to the video Jelly posted the pilots apparently had enough control of the aircraft to be able to fly further East and land from that side instead of making a direct return as first suggested by the controller.

Also interesting is that the engine was still on fire when they landed. I would have thought by shutting off the fuel and hydraulics to the engine the fire would have gone out..

Speaking only from my experience on the B737, you would be surprised how well the plane actually handles on one engine. It is VERY controllable and stable...



"If you’re a leader, you lead the way. Not just on the easy ones; you take the tough ones too…” – MAJ Richard D. Winters (1918-2011), E Company, 2nd Battalion, 506th Parachute Infantry Regiment, 101st Airborne

"Woe to those who call evil good, and good evil... Therefore, as tongues of fire lick up straw and as dry grass sinks down in the flames, so their roots will decay and their flowers blow away like dust; for they have rejected the law of the Lord Almighty and spurned the word of the Holy One of Israel." - Isaiah 5:20,24

Part of the takeoff briefing in the cockpit will include the dump time; dump time applies if the problem is such that it allows the time to do the fuel dump. Generally with a fire, it's more important to get back to a runway, and one isn't going to take time to run a fuel jettison.

As part of the briefing, we'll discuss the amount of dump time in minutes (eg, if we have to return, 23 minutes of fuel dump, etc), but also that if we're on fire, we'll do an immediate return and accept the overweight. We'll plan the runway for that event, which may not be the departure runway. It may also not be the departure airport, if a more acceptable option is nearby (longer, better facilities, better approach, etc). In some cases, it's more appropriate to turn around and land opposite direction.

Engine firefighting capability is largely restricted to the accessory section of the engine where the fuel pumps, hydraulic pumps, etc, are located, and in some aircraft, the pylon area that attaches to the wing. When the exterior of the engine nacelle has separated and the engine is exposed, there's nothing to contain the firex agent to extinguish the fire, and it is lost. Cutting off fuel, bleed air, hydraulics, and electricity reduces the ignition sources and fuel, but there's also an oil tank in there, and the oil and any fuels that have escaped, will burn until consumed. With the nacelle damaged, direct airflow turns the fire into a blow torch.

I was wondering if that was the synthetic engine oil burning.

I sure as hell wouldn't be dumping fuel out of the bottom of the plane with the engine on fire!

Fuel dump is away from the engines. Fuel is pumped into a crossfeed manifold that is connected between tanks and engines, and sent to jettison valves near the wingtips. Dump rate is several thousand pounds per minute.

Bear in mind that while the engine may be on fire, the fire is not at the dump valve, and there's a an extremely high volume of ram air flowing between the fire and the fuel dump, isolating the two.

Juan Browne knows whereof he speaks. From 2012:

Pilot Thomas “Juan” Browne describes landing on one engine at LAX on flight from Hawaii.

The video and report were excellent. Mr. Browne provided a calm, rational review of the event and detailed the procedures.

Training, well developed procedures and compliance to those procedures brought this event to a good outcome.

Juan Browne's explanations of the simulation training, flight planning, and pre-flight briefings of how to handle emergencies was extremely reassuring for us who are airline passengers!

Thanks, Jelly. I subscribed to the Blancolirio channel.

^^^^ His previous video gave a good explanation of how the decisions were quickly made as to which direction, etc, related to the questions asked above. You might watch it too.

I was on a plane that did something similar (at least to me the lay person) huge fireball down the side of the plane and pilot eventually announced we lost an engine. It obviously worked out and I'm glad it worked out for these folks here.

I know its a testament to the airframe and such but to this day I need to be about 4-5 sheets getting on a plane and have exhausted all alternatives previously.
