Crew communication
650 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: 09:40:00–09:49:43, 10:20:28–10:41:54 · 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.

“Not in transcript” never means “not said”: a line may be unintelligible, or the recording may not cover that phase.
