In September 2018, HAECO Hong Kong completed its first 4C heavy maintenance check on a Boeing 787-8 Dreamliner aircraft owned by United Airlines (UA). HAECO staff worked closely with UA and its suppliers during the input to ensure the highest levels of service and workmanship. Both companies have gained valuable experience through this project. This was the UA Dreamliner’s second visit to HAECO Hong Kong, following its first C check three years ago. HAECO Hong Kong has subsequently completed 4C checks on another two Boeing 787 aircraft for United Airlines.
