It seems that the Twitter post "good morning changi airport" does not relate to a maintenance report feedback to public flat house. Changi Airport is an airport located in Singapore, and it is not associated with public housing or maintenance reports. Therefore, the answer is "False" for the relatedness and "none" for the type, along with a brief explanation.
