Federal investigators are examining multiple factors in Sunday night's deadly Air Canada Express Flight 8646 crash at LaGuardia Airport, including potential issues with air traffic control systems and staffing.

The Air Canada Express aircraft crashed during what investigators describe as a routine landing that turned into disaster within approximately 20 seconds. Authorities are focusing their investigation on a key tracking system that reportedly failed to alert controllers before the fatal incident.

Investigators are analyzing the aircraft's flight recorders and cockpit voice recorders to determine the sequence of events leading to the crash. Officials are also examining whether air traffic control staffing levels may have contributed to the accident.

The crash has drawn comparisons to a previous LaGuardia disaster from March 22, 1992, which occurred exactly 34 years before Sunday's incident. Ohio resident Bart Simon, one of only 24 survivors from the 1992 crash, has spoken publicly about the recent tragedy.

The investigation into Flight 8646 remains in its early stages, with federal authorities working to establish a complete timeline of events. The crash marks another aviation incident at LaGuardia, an airport that has experienced significant accidents in previous decades.
