Reported occurrences
Transport Canada has 5 reports on file mentioning C-GDXX (1995–1997). None of them records damage to the aircraft. Reports are filed for bird strikes, air-traffic events and equipment issues whether or not anything was harmed, so entries here are routine.
Transport Canada describes CADORS entries as preliminary and unsubstantiated, and subject to change. Reports reach the system when somebody files one, so a clean record doesn't prove an aircraft has never been damaged. It doesn't replace a title search, an AD check, a pre-purchase inspection or the logbooks.
