  • B762, San Francisco CA USA, 2008 (Synopsis: On 28 June 2008 a Boeing 767-200 being operated as a Public Transport cargo flight by ABX Air (DHL) experienced a ground fire after loading had been completed and all doors closed and just before engine startup at night. The fire was located in the supernumerary compartment of the airplane. This compartment, which is present on some cargo airplanes, is located directly aft of the cockpit and forward of the main deck cargo compartment which is where the toilet, galley, and three non-flight crew seats are located (see diagram below).The flight crew evacuated the aircraft through the flight deck windows and were not injured, but the aircraft was substantially fire damaged and later classified as a hull loss.)
  • B735, en-route, SE of Kushimoto Wakayama Japan, 2006 (Synopsis: On 5 July 2006, during daytime, a Boeing 737-500, operated by Air Nippon Co., Ltd. took off from Fukuoka Airport as All Nippon Airways scheduled flight 2142. At about 08:10, while flying at 37,000 ft approximately 60 nm southeast of Kushimoto VORTAC, a cabin depressurization warning was displayed and the oxygen masks in the cabin were automatically deployed. The aircraft made an emergency descent and, at 09:09, landed on Chubu International Airport.)
  • A320, vicinity Dublin Ireland, 2015 (Synopsis: On 3 October 2015, an Airbus A320 which had just taken off from Dublin experienced fumes from the air conditioning system in both flight deck and cabin. A 'PAN' was declared and the aircraft returned with both pilots making precautionary use of their oxygen masks. The Investigation found that routine engine pressure washes carried out prior to departure have been incorrectly performed and a contaminant was introduced into the bleed air supply to the air conditioning system as a result. The context for the error was found to be the absence of any engine wash procedure training for the Operator's engineers.)
  • B738, en-route, near Sydney Australia 2018 (Synopsis: On 12 July 2018, a Boeing 737-800 was climbing through FL135 soon after takeoff from Sydney with First Officer line training in progress when the cabin altitude warning horn sounded because both air conditioning packs had not been switched on. The Captain took control and descended the aircraft to FL100 until the situation had been normalised and the intended flight was completed. The Investigation noted that although both pilots were experienced in command on other aircraft types, both had limited time on the 737 and concluded that incorrect system configuration was a consequence of procedures and checklists not being managed appropriately.)
  • B734, en-route, east northeast of Tanegashima Japan, 2015 (Synopsis: On 30 June 2015, both bleed air supplies on a Boeing 737-400 at FL370 failed in quick succession resulting in the loss of all pressurisation and, after making an emergency descent to 10,000 feet QNH, the flight was continued to the planned destination, Kansai. The Investigation found that both systems failed due to malfunctioning pre-cooler control valves and that these malfunctions were due to a previously identified risk of premature deterioration in service which had been addressed by an optional but “recommended” Service Bulletin which had not been taken up by the operator of the aircraft involved.)
