The IC arrived at the scene, inspected the aircraft, and interviewed the flight crew. Photographs of the aircraft and onboard documentation were taken. The Cockpit Voice Recorder (CVR) was seized, and Quick Access Recorder (QAR) data were downloaded and secured. Eyewitnesses were interrogated, and reports from involved services were acquired.
