Delta’s LAX Hangar Suffers Accidental Foam Discharge

An unusual incident occurred at Delta Air Lines‘ new hangar at Los Angeles International Airport (LAX). Earlier this week, there was an accidental foam discharge. This caused the whole hangar and the ground outside to end up covered in foam.

Quite a mess

The thick substance towered up to the wings of the Atlanta-based carrier’s smaller aircraft within the hangar. According to Tankdiver, a member of Airliners’ popular forum, staff could not contain the foam. Therefore, employees had no choice but to open the hangar door to let the material out.

There are reports on the website that a plane backed into the hangar with the auxiliary power unit (APU) on. This may have triggered the fire suppression system, forcing the foam to be dispersed.

Nonetheless, there most likely would have been some sort of heat within the building to cause the incident to occur. Alternatively, a sensor could have gone rogue. Staff at the site must have been panicking while the foam spread across the vicinity. Regardless, at least the aircraft here got a squeaky clean polish out of it.

Los Angeles presence

Delta operates at LAX’s Terminal 2, Terminal 3, and Terminal TB – Tom Bradley International Terminal (TBIT). The airline formerly departed from Terminal 5 and Terminal 6. However, it switched in spring 2017 as part of a $1.86 billion plan to improve operations in the Californian city.

Simple Flying reached out to Delta for comment on what happened at the LAX hangar. A spokesperson for the company shared that the fire suppression system in the hangar malfunctioned and caused foam to be dispersed.

However, Delta is still investigating the cause of the incident. Nonetheless, there was no impact on operations and the airline is working with its local environmental contractor to clean up the foam from the aircraft and hangar.

Volatile system

Last September, a similar incident happened at Airbus’ brand new manufacturing plant in Mobile, Alabama. A fire suppression system was activated, which caused fire-retardant foam to be sprayed all over the building. Additionally, the first A220-300 that was being assembled in the hangar got covered.

Ultimately, the system’s sensitivity shows that it can be relied upon if there was an actual fire. However, it looks there are some units that are extra fragile when it comes to a little bit of heat in the area. Therefore, it can be a costly job to clear up the mess if the foam is discharged without a proper reason.
