LEXINGTON, Ky. (AP) - The pilots of Comair Flight 5191 left the terminal the morning of the fatal crash at Blue Grass Airport in Kentucky last August without receiving crucial information at the airport.
Comair pilots had 15 updates - called Notices to Airmen - available through the airline's flight dispatch network the morning of August 27th, 2006.
But four NOTAMs - including the one detailing the closing of the taxiway normally taken to the main runway - were missing.
The flight crashed shortly after mistakenly taking off from the airport's general aviation runway, killing 49 of 50 people on board. Comair serves several airports in West Virginia.
The National Transportation Safety Board will release its findings and state a probable cause in the crash during a meeting in Washington, D-C, on Thursday.
The N-T-S-B's report will likely bring to light the problems with the NOTAMs. Pilots say the system is outdated and difficult to understand.
The N-T-S-B cited NOTAM-issues as a contributing factor in 30 accidents and incidents between 1991 and 2006.
