Spilled beverages in the cockpit are connected to two episodes where a plane’s engine shut down at the center of a flight, based on aviation publication FlightGlobal.

Both sudden shutdowns were about the brand new Airbus wide-body jet, the A350, also included Rolls-Royce Trent XWB engines.

Among the shutdowns was on a Delta Air Lines flight from Detroit to Seoul, South Korea, on January 21. The flight was previously northern Canada whenever the engine switched off. The flight diverted to Fairbanks, Alaska and was finally canceled, based on data in FlightRadar24.

Based on FlightGlobal, a drink was spilled in the cockpit approximately 15 minutes prior to the engine shut down itself. The liquid ended up on the middle pedestal between the 2 pilots, close to a panel that’s used to control and start engine works.

Following the search motor shut down, pilots attempted, unsuccessfully, to resume it. This was when they decided to divert into Alaska.

FlightGlobal reported an investigation of this flight-data recorderblack box, revealed”the digital motor control had controlled closed of a high-pressure shut valve following erratic output by the integrated control panel”

Another incident happened on November 9, 2019, roughly an hour after a cup of tea spilled on precisely the exact same base of A350-900. The airline wasn’t identified, but seems to have been Asiana, a South Korean airline.

Likewise to the subsequent episode, the right-side motor shutdown and may not be resumed successfully. The flight-data recorder revealed a similar high-pressure closed off valve closed.

Based on FlightGlobal, the control panels on both the aircraft were substituted, and Airbus is exploring the shutdowns while warning airline clients to prevent spills.

Airbus declined to comment to Business Insider about the particular cases, but stated that it had been in”regular dialog with our clients keeping them abreast on newest operational issues.”

“Safety is a top priority in air travel, and also this continuous conversation is a powerful contributor to the superb security track record we see now in air travel,” a spokesperson added.

Many eagle-eyed aviation fans noted that although the A350 features cupholders from the cockpit, they are smaller than are located on other planes.

Although spills could be cluttered or inconvenient, the prospect of a cup of java inducing a plane’s motor to close down during a trip is alarming.

Marc Rochet, the president of French Bee, a Paris-based budget airline using the all-A350 fleet, advised Business Insider cabin and cockpit crews are especially trained on how best to take care of fluids near controllers to prevent a similar episode in their A350s.

“We left a broad instruction to our team several months ago due to the central engine controllers,” Rochet explained. “The cabin crew can’t offer any drink into a cockpit team member at the middle region of the cockpit. They must pass it around on the side.

“Years before, the controllers were completely mechanical. If you spilled water, then you’d only wait for it to dry, then it’d be OK. Now it is all computers, and computers and liquid don’t match.”

Delta and Asiana didn’t immediately return a request for comment.
