Regarding probable cause, the synopsis of the NTSB's report on the Comair 5191 accident, issued today, concludes:
The National Transportation Safety Board determines that the probable cause of this accident was the flight crewmembers’ failure to use available cues and aids to identify the airplane’s location on the airport surface during taxi and their failure to cross‑check and verify that the airplane was on the correct runway before takeoff.In addition to ruling on probable cause for the accident, the NTSB report also issued numerous safety recommendations for the FAA to consider -- some new, some reiterated. In summary, the safety recommendations focus on the need for:
Contributing to the accident were the flight crew’s nonpertinent conversations during taxi, which resulted in a loss of positional awareness and the Federal Aviation Administration’s failure to require that all runway crossings be authorized only by specific air traffic control clearances. [NTSB/AAR-07/05]
- improved flight deck procedures
- the implementation of cockpit moving map displays or cockpit runway alerting systems
- improved airport surface marking standards
- ATC policy changes in the areas of taxi and takeoff clearances and task prioritization
The NTSB synopsis issued today will be followed at a later date by the Board's final report, which will include the Board’s rationale for the conclusions, probable cause, and safety recommendations.
