Dornier 228 Certification
Note that the Dornier 228 is certificated to FAR 23 up to amendment 23. That means it has no requirement whatsoever to withstand a bird strike. It could legally be downed by a well aimed sparrow! Once up on a time such aircraft were limited to max 9 pax. The story of how 19 occupants came to be put at risk dispels forever the myth that "safety is paramount"
