Conditions of freezing drizzle, known as hard rime, were the most likely cause of the tragedy. The National Transportation Safety Board (NTSB) has announced that they would send a team to the crash site on Friday to begin the investigation. Lorenda Ward will serve as chief investigator with the assistance of NTSB Commissioner Steven Chealander and public affairs officer Keith Holloway. Ward has investigated several other plane crashes ―including the 2006 New York City plane crash that claimed the life of New York Yankees pitcher Corey Lidle.
