Delta Air Lines suffered a foam dispersion incident in Los Angeles International Airport (LAX) after a fire suppression system malfunctioned inside the airline’s hangar.

A representative from the airline confirmed the news to AeroTime.

“The fire suppression system at our hangar malfunctioned and caused foam to be dispersed,” the spokesperson explained to AeroTime News via email. “We are working with our local environmental contractor to clean up the foam from our aircraft and hangar.”

While according to the spokesperson there was no “impact to our [Delta Air Lines – ed. note] operations,” posts on social media indicated that a Boeing 777 was parked at the hangar at the time of the incident, which occurred on March 23, 2020.

Potentially, the aircraft involved could be a Boeing 777-200ER, registered N867DA, which was delivered to Delta Air Lines on March 15, 2002. Flight tracking website indicates that the aircraft operated Flight DL6 from Tokyo Haneda International Airport, Japan (HND), to Los Angeles International Airport (LAX) on March 22, 2020, with no further activity since. The airline’s other Triple Sevens are either operating flights at the moment or were sent to storage a few days prior to the foamy dispersion in Delta’s hangar in the City of Angels.

While the airline’s spokesperson indicated that the company is still investigating the cause of the incident, a user on social media stated that the rain caused a short circuit in the fire suppression system, triggering the discharge of foam in the hangar.

Airbus has suffered an incident in its plant in Mobile, Alabama, as a fire suppression went off at one of the hangars. Potentially, two planes are damaged:
