What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Pilot had just begun a descent from 6000 feet to 3000 feet when he heard the sound of air coming from the back of the cherokee six. A second or two later there was a loud popping noise and a greater rush of air. The pilot then turned around to find the top half of the passenger door missing. He was about 20 nautical miles from his destination (the condord, north carolina airport, jqf). A landing was made with no further problems. The pilot stated that the subject passenger door was securely fastened prior to the flight's origin.
