Cathay Pacific will be adding inflight and post-landing checks on emergency equipment on board its aircraft, after it uncovered 6 instances of tampered portable oxygen bottles. The carrier states that the 6 incidents occurred over a month, between August and September. The latest took place Sept 16 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. 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. <br/>
