The post does not relate to a maintenance report feedback to public flat house. The post mentions a parked aircraft, specifically a Hainan Airlines Dreamliner, but it does not mention any issue or inconvenience related to public housing. Therefore, the answer is "relatedness": False and "type": "none".
