What happened
On 13 April 2003, a Chaser-S, registration G-MVZY, was involved in an accident near Clitheroe, Lancashire. While the specific details of the impact were documented in previous reports, recent corrections to the flight data analysis have clarified the aircraft's movement prior to the event.
The investigation
During the review of the GPS route information, investigators identified a directional error in the initial publication of the accident findings. The investigation established that the flight path data had incorrectly described the aircraft's heading during its final maneuvers.
Findings
Data analysis confirms that the aircraft performed a sequence of gentle turns before reaching the accident site. Contrary to earlier reports suggesting an easterly direction, the corrected data indicates the aircraft maintained a mean westerly track during these turns.
