Hypothetically, what happens if that pilot decides to save the AAIB a lot of work and tells them, "I completely forgot to lower the undercarriage, don't know what I was thinking"? Or if a mechanic states that he omitted to tighten a hydraulic connector correctly, causing the undercarriage to malfunction?
Does the report merely state that there was no evidence of malfunction (in the first case) or that the connector was examined and "appeared" to have been incorrectly tightened?
Not suggesting any parallels with the cause of this incident, but genuinely curious as to how far the AAIB go to spare the blushes of an individual who admits some liability?
