Quote
LOS ANGELES - Jet fuel dumped from a Delta airliner preparing to make an emergency landing at Los Angeles International Airport fell over a wide swath of the area, sending hazardous-materials teams to multiple schools,but only minor injuries were reported and nobody was hospitalized.

Officials say 60 people have been treated including elementary school students after a plane dumped fuel on the school's playground near Cudahy and South Los Angeles schools on Tuesday.

Quote
“Shortly after takeoff, Flight 89 from LAX to Shanghai experienced an engine issue requiring the aircraft to return quickly to LAX. The aircraft landed safely after a release of fuel, which was required as part of normal procedure to reach a safe landing weight. We are in touch with Los Angeles World Airports and the LA County Fire Department and share concerns regarding reported minor injuries to adults and children at a school in the area.”

Do you think they will demand jets start landing fully fueled?

This makes me wonder why they didn't go over the ocean to dump fuel? We would go out over the deep blue, stay above 6K and dump away unless it was a get on the ground right now type of emergency. I only had one of those, a tailpipe fire out by San Clemente Island and we trailed smoke all the way to Vandenburg to land. Our fire suppression system wouldn't reach the tailpipe. Sad

San Clemente to Vandenberg? What kept you guys from landing at Mugu or San Nic (I think the outer landing field at Nic is long enough)?

16000 ft runway at Vandenberg, we had already turned north to head toward home/land by the time we figured it was not going to burn itself out. So Vandenberg it was. Worked out fairly nice, we were able to throw a new turbine in a maintenance van and drive it down there to change it out. Our rear turbine scavenge pump bit the bullet and dumped oil into the tailpipe. The only time we ever went to San Nicholas was to drop mines. We would do our 9 plane mine laying exercise there.

Ah, okay. I thought it was a "put down now" thing. Vandenberg does have a luxurious runway. I always cracked up when we landed our little puddle jumper on the numbers there and still had a half day's worth of runway left.  laugh

It was a great runway. We could do a full stop landing, stay on the runway and do an aborted takeoff and still have enough runway left to stay on the runway and take off to go do it again. We loved to do pilot training flights down there because we could get in a ton of runway work. Smiley

I expect some changes coming to this section of the 7110.65
https://www.faa.gov/air_traffic/publications/atpubs/atc_html/chap9_section_4.html
Notably:
Quote
9.4.3
ALTITUDE ASSIGNMENT
If an aircraft is dumping fuel in IFR conditions, assign an altitude at least 2,000 feet above the highest obstacle within 5 miles of the route or pattern being flown.

I've done this procedure dozens of times in my career.  This is the first time I've ever heard a problem.
I'm real curious if it was last minute.  Depending on the type of emergency, some will just burn fuel rather than dump.

LAX is right on the water.  Do they have landing approaches coming from the ocean side?  

I flew in there once before, but I was thinking the approach came in from the East (it was maybe 2005 so my memory may be fuzzy).  All I remember is looking out the window as we turned into the approach and seeing lights for a couple other jets apparently landing just ahead of us.

The news I heard this morning said they had a compressor stall on climbout so he decided to turn back. If he had just left and was heading to China he was probably overweight for a landing, or at least in the range where an inspection would have to be done for an overweight landing so he probably figured he could dump fuel and not make an overweight landing. But we weren't there so we will probably never know, it is all supposition at this point. BTW, I have bathed in JP4/5 in the distant past and I seem to be OK. Wink

Sometimes that's because the particular aircraft doesn't have provision for dumping fuel. IIRC, the Boeing 737 is one that doesn't.

Us small boys can't dump fuel.  I don't think any narrow-body can.

Things I learned today:

(1) Fuel dumps are not for purposes of reducing fire risk, which is what I always thought.  (Although I suppose this may be a factor in some cases.)

(2) Dumped fuel can interfere with other aircraft's engine functions, so isolation and altitude is necessary-desirable.

(3) Jet fuel is not necessarily dangerous by contact. ("Treated," apparently, can mean washing off of fuel on skin.)

(4)  If maximum fueled takeoff weight is 105% of maximum landing weight, fuel dump systems are sorta-kinda necessary for long range aircraft --apparently on a design-by-design and customer order basis.

Hm.  Ooookay.  Now I'm four three days ahead of myself from  the "learn one thing a day" perspective.

Thanks, all.

It’s pretty much Kerosene. So don’t drink it or get it in your eyes and it isn’t really that big of a deal.

That's what I always figured, so it's not a new "learn."  I could never stand the smell of kerosene or diesel/jet fuel (or diesel/jet exhaust) so I'll never buy a jet plane. :eyeroll:

I used to hate getting stuck behind a transit bus until they started stacking the exhaust at the roof instead of at ground-level... so apparently I'm not the only one who hates it.

I am picturing a bunch of kids on the playground looking up at the big jet moving away trailing fuel as kerosene rains out of the sky.

What's "SH" stand for?  I'm sure it's perfectly obvious and I'll dopeslap myself when you tell me, but I'm drawing a blank. Face Palm!

I guess  you can't stay up if your lift is all horizontal, hey?  You've got to get pretty ballistic to make that one work.

The odd thing is he had an advisor aboard who was going to report on his piloting safety since he had a number of prior complaints about his "sierra hotel" extreme behavior.

All too often though when the SH pilot overflies his ability it is not only he who pays the price. The accident investigation on this one brought a lot of behavior to light that should have never happened and it started long before the crash. It sucks when your friends die needlessly. Sad

Interesting that came up. Col. Robert Wolff was on that plane. I knew his folks and know his widow. My son dated his daughter for a short while.

His parents lived in Lubbock and went to my church. Nan and her daughter Whitney moved there after this crash. He was retired. Upon the completion of that flight he was out. His wife and daughter were waiting in the car for him to land. They were packed and ready. Moving truck had already left. He was walking off that plane and out of the Air Force.

Suck is heavy on that deal.

I didn't read the type ac from the article. I'm thinking internationals, like 77's and 78's.  The only smaller international flights we see at IAD are a few 75's and a brand new Neo flown by TAP.
I've had DLH and CCA both dump fuel or burn fuel before an emergency return. 
Domestic flights can still land our long runway loaded down.

Runway length is only part of the equation. Each aircraft has a maximum take-off weight and a maximum landing weight. For some, the maximum landing weight is significantly less than the maximum take-off weight. The reason is usually the concern that the undercarriage isn't robust enough to handle that amount of weight if the landing is at all rough.

Flys320s, feel free to correct me if I'm wrong.
