Delta LAX hangar foam discharged accident

Tue Mar 24, 2020 1:27 am

Delta's LAX new hanger had an accidental foam discharge overnight. It was pretty thick, up to the wings of some smaller aircraft.

This happened to two Jetstar A320s in Newcastle a few years back. A very expensive sensor fault.

If so much is outside, is it through the roof inside ?

It didn't go through the roof...they opened the hangar door to let it out once they figured they couldn't stop it.

Aircraft was backed into the hangar with APU on which triggered the fire suppression system in the hangar.

It happened again? lol
There was a hangar in LAX that accidentally activated the foam suppression and they opened the hangar door to let the foam out but I don't know if it was the Delta hangar.

within the last two or three years is what I remember.

Taken from a reddit thread on the subject, for what it's worth
The rain shorted the fire suppression system for the new hangar, possibly incorrect installation. No single persons fault. B777 was parked inside during this time, potential dual engine change.

Interesting...so now we have a rain theory, and an APU operational in the hangar theory...

I’m reminded of an ancient movie, Bachelor in Paradise. Washing machine with too much detergent and foam is pouring out of the service porch window. A little kid on the sidewalk blurts ou, “Look,mommy, that house is throwing up!”

Roughly how many gallons of water and gallons of foam agent are needed to create this much foam?

the AFFF foam i am used to is 94:1... so one gal of foam concentrate to 94 water = 95 gal of foam...

or if you're using 5 gallon AFFF concentrate jugs - a 5 gal AFFF concentrate jug will last you approx 4 minutes coming out of a tiny 1.5-inch fire hose or 2 minutes coming out of a standard 2.5-inch fire hose.

What is it about the retardant foam that makes it so corrosive/damaging to planes?

Quite a few hangars are built with the idea of keeping the rain out. Perhaps because it never rains in southern california---

Didn't something similar happened at AA's newly built hangar at GRU some months ago??

Update: Yes it did:

Wouldn't you have to have the APU on to brakeride it?

Can't answer that question, but many years ago when I worked on the ramp for UA at IAD, we had a 777 Captain retirement water cannon salute where the airport CFR accidentally had it switched to foam (not water). One of the engines ingested the foam and had to be replaced. After that they suspended water cannon salutes. That stuff is not liked by engines.

Only if you don’t have brake pressure built up. And if the hydraulics are electric the batteries can run them. As long as the tug is attached you don’t need power.

Was working that night, was driving the supertug towing our WN aircraft to park at the Qantas pad that night. Was just casually towing the aircraft when pulling in between the QF and DL pads it was spewing all that foam into the air and onto the zipper road. Found it soo hilarious with a 767 in the hanger and foam all the way up to the fuselage.

I'm not buying that. Granted these are likely older planes but the amount of damage usually isn't as bad as a writeoff, otherwise what's the point of the expensive foam system?
They can and will be repaired unless there are other problems with the planes unrelated to the foam.

Agreed...methinks that its another "a.net myth" (and there are many) that the foam is "super corrosive". This does happen from time to time and those planes are most certainly neither written off nor corroded to the point of major repair. In fact, most are back flying within days...I can speak from experience on that.

Perhaps it is just my mood today but I am not seeing the humor in this. It is another economic as well as environmental mess. Is it "soo hilarious" because you do not like Delta?

I try to find humor in what all of us airline employees are going through right now. LAX is a ghost town at the moment, terminals are empty. And that’s no laughing matter.

I have friends at DL and worry about there job safety as well as mine as we go through this downturn. Shit happens, there’s things that happen every single day at LAX and many other airports that never make the news that lots of us find humorous. Lighten up bud.

Sorry "bud". Just not finding humor in the pain of others having accidents or losing their jobs. It seems you still have a job for now. Good for you. I wish you the best.
