Construction lights were so bright they were confusing to pilots who tried to land at night in July 2017 when a fatigued Air Canada crew almost struck 4 aircraft on the ground in San Francisco, according to preliminary reports. The NTSB released more than 500 pages of investigative reports Wednesday, but didn’t reach conclusions on what caused the airliner to come within feet of triggering a catastrophe. Both pilots reported that they felt fatigued in the latter stages of their flight from Toronto. The captain told investigators he may have gotten less than 6 hours of sleep and his rest had been disrupted by a late flight the previous night. As the Air Canada plane approached the runway, the co-pilot thought something “didn’t look right,” he told investigators. However, he wasn’t certain what was wrong and was “unable to process what he was seeing”. <br/>

Air China has grounded some of its Boeing 787s powered by Rolls-Royce Trent 1000 engines, which had been found to have vulcanisation and fatigue cracks in the blades of the engine’s intermediate pressure compressor. In April, Rolls-Royce warned airlines that additional checks of its Trent 1000 engine powering the 787 would be needed to better understand the durability of the Package C compressor, featured on nearly 200 787s worldwide. Air China has replaced the grounded 787s with Airbus A330s and Boeing 777-300s to operate on international routes including Beijing-Los Angeles, Beijing-New York Newark and Beijing-Singapore to avoid flight disruptions as the carrier steps up inspections of Rolls-Royce engines. Air China is the only Chinese carrier that has equipped its 787 aircraft with Rolls-Royce engines. <br/>
