Incident Overview
On 11 December 2021, a Boeing 737-800 (registration EI-EMM) arrived at Dublin Airport following a scheduled flight from Arrecife Lanzarote Airport. While passengers were disembarking via the forward integrated airstair, one passenger fell from near the top of the stairs. The falling passenger collided with another passenger standing on the apron, who attempted to break the fall. The first passenger sustained serious head injuries and was transported to hospital; the second passenger reportedly sustained minor injuries.
Airstair and Conditions
The aircraft's airstair was approximately 0.62 meters wide, narrower than standard mobile stairs. It was equipped with non-slip treads, retractable safety barriers, detachable handrail extensions, and warning signs about small children. According to the investigation, no defects were found on the airstair or surrounding area after the incident. The cabin crew reported the airstair was dry at the time. The area around the aircraft was well lit, and the ground appeared wet. Meteorological data from Met Éireann indicated light rain, cloudy conditions, a south-westerly wind of 5–9 knots, visibility of 20 km, and a surface temperature of 11°C.
Sequence of Events
CCTV footage showed the passenger holding both handrails while carrying an item of clothing in their right hand. The passenger stepped onto the top step with the left foot, then placed the right foot beside it on the same step, repeating this on the second step. When moving to the third step with the left foot, the passenger appeared to fall forward while trying to place the right foot on the fourth step. No stumble or clothing catch was observed. A second passenger waiting nearby attempted to catch the falling individual. Ground staff and cabin crew provided immediate assistance; an ambulance arrived approximately seven minutes later.
Operator Procedures
The operator had a standard disembarkation announcement reminding passengers to use handrails and for those with children to hold hands. The crew confirmed the announcement was made prior to disembarkation. The investigation attempted to contact the injured passenger through provided details but received no response.
Investigation Findings
The investigation reviewed the airstair design, certification, and previous occurrences. The airstair met applicable certification specifications; however, integrated stairs are not subject to specific EASA CS-25 certification standards as they are not deemed critical to aircraft operation. The report noted that the operator had incorporated manufacturer-approved safety modifications, including non-slip material and warning placards.
