AAIB investigation to ERJ 190-200 LR (Embraer 195), G-FBEJ
Smoke and fumes in cabin during takeoff, resulting in emergency evacuation, Exeter Airport, Devon, 28 February 2019.
Summary:
As the thrust levers were advanced for takeoff, on an early morning scheduled passenger flight, the flight crew detected an unusual odour and observed smoke entering the cockpit. They then moved the thrust levers to the idle position and applied the parking brake. The cabin crew subsequently reported that there were smoke and fumes in the cabin. Following an assessment of the situation, the commander initiated an emergency evacuation. During the evacuation, passengers who evacuated via the overwing exits reported being unsure of how to get down from the wing to the ground and several re-entered the cabin and exited via one of the escape slides.
The smoke and fumes were subsequently attributed to an incorrectly performed engine compressor wash procedure, which was carried out by maintenance personnel the night before the occurrence flight.
As a result of the findings of this investigation, the European Union Aviation Safety Agency (EASA) has undertaken two safety actions relating to the certification requirements for overwing emergency exits. The operator has also undertaken several safety actions relating to passenger safety briefings, processes for maintenance planning, engineer training, competency and welfare and monitoring of ground equipment.
Four Safety Recommendations are made relating to the certification requirements for overwing exit markings and the height requirement for overwing exits to be equipped with an assisted means of escape.
