British Airways Crew Member On Second Day Of Work Deploys Emergency Slide, Delays Flight By 6 Hours

A seemingly small mistake by a newly appointed British Airways crew member led to a six-hour delay, just before the flight was going to take off. The incident took place on May 16 at around 12:35 pm, as British Airways flight BA217 was preparing for departure from Terminal 5 at Heathrow Airport.

The Boeing 777-200 aircraft, which was scheduled to fly from London Heathrow to Washington Dulles, had already begun pushback from the gate when the error occurred.

The crew member involved was on their second working flight after completing initial training, according to information shared by sources cited by the cabin crew Facebook group 'A Fly Guy's Cabin Crew Lounge'.

The crew member misinterpreted a standard instruction - "doors to automatic". This command is used to arm the emergency evacuation slides so that they deploy automatically if the doors are opened during an emergency.

Instead of simply arming the system, the crew member mistakenly pulled the door opening lever. This action activated the emergency power assist system, forcing open the door and deploying the slide at Door 3L - the third door on the aircraft's left side. British Airways has not officially confirmed the cause of the slide deployment.

Following the incident, the airport fire brigade was called to the scene as part of standard safety protocol. The aircraft was temporarily grounded while checks and necessary reset procedures were carried out.

Eventually, the same aircraft was cleared for departure and took off at around 7 pm - more than six hours after its scheduled time.

What Are Inadvertent Slide Deployments?

Such incidents are known in aviation as inadvertent slide deployments (ISDs). According to aircraft manufacturer Airbus, around three such incidents occur globally each day.

ISDs typically happen when cabin crew accidentally open aircraft doors while the emergency slides are still armed - often due to fatigue or distraction after landing. However, cases where a crew member both arms the slide and immediately opens the door are far less common.

Training Concerns Under Spotlight

Some aviation experts believe such errors may point to deeper issues in training methods. As reported by PYOK, new recruits may develop a sequence-based muscle memory where arming the door is subconsciously linked with opening it during emergency drills.

The recurrence of such incidents at British Airways has drawn attention. The airline has reported a cluster of similar cases in recent years, particularly involving new crew members.
