Cathay steps up emergency equipment checks
September 23, 2019
Cathay Pacific will be adding inflight and post-landing checks on emergency equipment on board its aircraft, after it uncovered six instances of tampered portable oxygen bottles. The carrier states that the six incidents occurred over a month, between August and September. The latest took place on 16 September and involved one portable oxygen bottle, which had a shut-off valve “inadvertently” opened by cabin crew during a routine check. This led to the bottle to be found in a low-pressure state. Three other instances also involved a single oxygen bottle, and were found on Cathay Dragon flights. The last two incidents occurred on the same flight, CX826 from Hong Kong to Toronto, a day apart. On 17 and 18 August, five and eight out of 22 portable oxygen bottles respectively were found to be in low pressure state. Cathay states that the issues were uncovered during routine pre- and post-flight inspections. Internal investigations into the matter are ongoing, says Cathay, and cabin crew from the flights involved have been suspended from duties. Some have since returned to work, while others are still assisting investigations. The airline has also informed the Hong Kong Civil Aviation Department and the police. It stressed that passenger and crew safety were compromised by the incident, and that the oxygen bottles were checked and recharged upon discovery. Portable oxygen bottles are used to allow crew to move around the cabin during cabin depressurisation. Passengers, as well as cabin crew, have in-seat oxygen supply, and this was not affected by the spate of incidents.

Second Swiss A220 suffers similar engine rotor failure
September 23, 2019
Investigators are probing another serious engine failure on a Swiss Airbus A220-300, less than two months after a previous similar incident involving a sister aircraft on the same route. The aircraft (HB-JCA) had been operating Geneva-London Heathrow on 16 September when the failure occurred in the left-hand Pratt & Whitney PW1500G engine during climb. US National Transportation Safety Board investigators state that the incident took place just before the twinjet reached its cruising altitude of 35,000ft. The crew returned to Geneva after carrying out quick-reference handbook procedures and declaring an emergency. Inspection of the aircraft after it landed showed that the stage-one rotor in the low-pressure compressor had separated and there was a hole in the compressor case. None of the 77 occupants were injured. French investigators were already looking into the failure of the left-hand PW1500G on another Swiss A220-300, under similar circumstances, on 25 July. The aircraft (HB-JCM) had departed Geneva for Heathrow and had been climbing through 32,000ft when the failure occurred. Investigation authority BEA subsequently sought public assistance to find engine components which they believe were shed from the aircraft over France. The stage-one rotor of the low-pressure compressor was found to be missing after the jet diverted to Paris. The aircraft involved in the latest incident was delivered to Swiss in May 2017. It had been operating the LX358 service while the earlier event occurred to flight LX348.

Vietnam 787 on final told undercarriage still retracted
September 20, 2019
Investigators are probing an incident in which a Vietnam Airlines Boeing 787-9 executed a missed approach after being informed by air traffic control that the undercarriage was not deployed. The aircraft had been operating to Melbourne on 19 September, having departed from Ho Chi Minh City. “During approach to land, Melbourne air traffic control advised the crew that the aircraft’s landing-gear was observed not to be extended,” says the Australian Transport Safety Bureau. The aircraft had been conducting its approach to runway 34, and executed a go-around. Visibility at the time – around 08:04 – was good, and there was no adverse weather, according to meteorological data from the airport. Investigators have not disclosed the altitude of the 787 or its distance from touchdown at the point when the undercarriage advisory was transmitted. The flight, after carrying out the missed approach, landed around 15min later. The bureau says it will “obtain information from the flightcrew and additional information as required”.
