Distress-related logs must be kept for three years from the last date of entry. This retention period ensures there is a lasting record of any distress, urgency, or safety communications that could be reviewed later for regulatory investigations, training, or incident analysis. So, after the final distress entry, hold onto the log for three full years. The other durations—one year, five years, or ten years—do not align with this required period.
