Crew communication
412 lines readobservations a human-factors reviewer takes from a transcript — the sterile cockpit, the Board's own notations, rhythm, CRM markers. Not emotions, not scores: the affect is in the audio, and the audio is sealedWindows: 00:38:09–00:58:52, 11:18:06–11:28:01 · basis: recorder pressure altitude below 10,000 ft. Candidate non-pertinent lines below are a first reading for the investigator, not a finding; “@” marks the Board's own non-pertinent-word notation.

Read next to the Board’s coded human-factors findings on the case page. The NTSB cautions that a transcript is not a precise science; these are pointers into it, for a trained reader to weigh.
