The NTSB released numerous documents Tuesday morning to coincide with the start of their hearing on the crash of Flight 3407.

The two Pinnacle Airlines Corp. pilots violated rules against unnecessary cockpit chatter minutes before a February crash near Buffalo, New York, that killed 50 people, a U.S. safety board said.

First Officer Rebecca Shaw and Marvin Renslow, captain of the plane, chatted about flying experiences, career goals and other matters unrelated to their tasks as they communicated with air-traffic controllers and went through a checklist for landing. Less than four minutes before the plane went into a fatal dive, Renslow recounted flying in West Virginia and Florida.

One of the documents made public for the first time is the transcript of the audio captured by the Cockpit Voice Recorder.

The following is a conversation about icing between Captain Renslow and First Officer Shaw. It began shortly after passengers were told to take their seats, turn off portable electronic devices, and prepare for landing. The conversation lasted for nearly three minutes. During that time, Renslow and Shaw also prepared for landing and communicated with the tower. Those communications are included in the full transcript.
