Graham said "This is the beginning of a long process" and "the NTSB is currently focusing on three distinct elements being the human factor, the aircraft itself and the environment."
At this time, teams are gathering evidence at the scene including personal items that may contain additional clues. Graham went on to emphasize that the NTSB will not be drawing any conclusions until all forensic study is completed which will include moving the wreckage to a secure location for further investigation.
He added that anyone including witnesses or who otherwise might have pertinent information to please contact the NTSB at witness@ntsb.gov
The NTSB will make a preliminary report available in about 30 days however, a full investigation likely will take 12 to 18 months to complete.
