A Delta Air Lines (DL) flight attendant accidentally deployed the emergency evacuation chute on an Airbus A220 at Pittsburgh International Airport (PIT) on Saturday evening (October 25, 2025).
This resulted in damages estimated at around $70,000, according to the Aviation Z2Z report. The flight was also delayed by four hours, from 17:30 to 21:11.
what exactly happened
The 1L boarding door was opened when armed, so the chute automatically deployed on the ramp.
The crew member, a 26-year veteran, accidentally lifted the door handle after securing it for departure, triggering the automatic ejection of the forward left slide mechanism — the same door used to attach the jet bridge.
As the plane prepared to bounce, the flight attendants disarmed the doors in accordance with standard pre-departure procedures.
The front crew member then “inadvertently” lifted the door handle while the system was activated, activating the emergency booster function, the report added.
When switched on, the mechanism automatically forces the door open and extends the slider in seconds, leaving no time to stop the process.
The deployment caused an operational shutdown.
The price of a mistake
Emergency evacuation slides are expensive components, with replacements for smaller jets like the A220 typically costing between $50,000 and $70,000, the report claims.
In addition, repacking and repair can cost $20,000, while the total cost of the event, including hotels, crew and relocation, can run into six figures.
The passengers were trapped
When the slide inflated directly against the jet bridge, passengers were temporarily trapped on board until engineers manually disconnected the slide and reconnected the bridge.
It then took “about an hour” to disconnect and remove the slide. Meanwhile, the flight attendant apologized and said this had never happened in her “26-year career”.
AND Reddit post stated: “The flight attendant accidentally deployed the emergency chute… He apologized and was quite upset, as reported in a 26 year career, this has never happened. But can someone explain how? Shouldn’t it be something with quite a safety check for making such a mistake?”

A number of passengers then made a bad connection in Salt Lake City and were stranded where they spent the night, although some would be rebooked, particularly via Atlanta, another report said.
Understanding Inadvertent Image Deployment (ISD)
ISDs are uncommon but not rare.
Airbus data from previous years indicated an average of up to three inadvertent deployments per day across the global fleet.
Most occur during the post-landing disarmament phase, when crew members prepare to open the doors for arrival.
Despite strict cross-checking procedures designed to catch such mistakes, mistakes still happen – especially at stations where one flight attendant works alone at the front door.
The risk is not only financial.
An unplanned deployment on arrival could seriously injure ground personnel or damage nearby equipment such as jet bridges and service vehicles. Some airlines are aware of this and have introduced additional safeguards.
