Cabin Fumes from Non-Fire Sources
From SKYbrary Wiki
Non Combustion-related Fumes
|Category:||Fire Smoke and Fumes|
Fumes from various non-fire related sources may sometimes be experienced within the cabins of passenger aircraft.
Most modern passenger aircraft are equipped with pressurised, climate controlled, cabins. In spite of the aircraft designers’ intentions, unwanted fumes frequently permeate the interior of the aircraft. Open doors and hatches as well as certain on-board sources can introduce fumes to the cabin environment. However the usual path of entry for fumes is via the aircraft pressurisation and air conditioning systems.
The majority of passenger aircraft utilise bleed air from the engine or Auxiliary Power Unit to pressurize and heat or cool the aircraft cabin. As a consequence, any contaminants introduced into the engine/APU compressor prior to the point from which the bleed air is extracted may result in the appearance of corresponding fumes in the passenger cabin and flight deck.
Accidents and Incidents
Cabin air contamination
- B738, Glasgow UK, 2012 (On 19 October 2012, a Jet2-operated Boeing 737-800 departing Glasgow made a high speed rejected take off when a strange smell became apparent in the flight deck and the senior cabin crew reported what appeared to be smoke in the cabin. The subsequent emergency evacuation resulted in one serious passenger injury. The Investigation was unable to conclusively identify a cause of the smoke and the also- detected burning smells but excess moisture in the air conditioning system was considered likely to have been a factor and the Operator subsequently made changes to its maintenance procedures.)
- B734, vicinity East Midlands UK, 1989 (On 8 January 1989, the crew of a British Midland Boeing 737-400 lost control of their aircraft due to lack of engine thrust shortly before reaching a planned en route diversion being made after an engine malfunction and it was destroyed by terrain impact with fatal or serious injuries sustained by almost all the occupants. The crew response to the malfunction had been followed by their shutdown of the serviceable rather the malfunctioning engine. The Investigation concluded that the accident was entirely the consequence of inappropriate crew response to a non-critical loss of powerplant airworthiness.)
- B763, Frankfurt Germany, 2007 (On 20 August 2007, at Frankfurt, while a Boeing 767-300 was taxiing to its parking position, thick smoke developed in the passenger cabin. All passengers and the crew were able to leave the aircraft at the gate without further incident.)
- MD11, en-route, Atlantic Ocean near Halifax Canada, 1998 (On 2 September 1998, an MD-11 aircraft belonging to Swissair, crashed into the sea off Nova Scotia following an in-flight electrical fire.)
- B744, Phoenix USA, 2009 (On 10 January 2009, a Boeing 747-400 being operated by British Airways on a scheduled passenger flight from Phoenix USA to London had been pushed back from the gate in normal daylight visibility and the engines start was continuing when fumes and smoke were observed in the cabin and flight deck. The aircraft commander decided to return to the stand but there was some delay while the tug was reconnected and the movement accomplished. The intensity of the fumes increased and as the aircraft came to a halt on the stand an emergency evacuation was ordered.)
