You're right! This may have been an incident, but it was not an accident!
In the incident recorded (somewhere by somebody) on my plane, the NTSB would not require a report, assuming there was in fact no injury or damage to the aircraft or private property! Being an off airport forced landing, the FAA may have required a report. I think he landed on a highway, so local Law enforcement may have played a role, and may have notified the FAA. The pilot or owner may have reported it! The FAA may have taken enforcement action against the pilot, and the appearance of the N number in the report may have trigered the entry in the (unknown) records above. But I am still at a loss as to where I would get a copy of that report, based on my N number alone!
