It's a bit hard when the investigations are not all complete, whilst often taking years to be published, if at all
You are quite correct Squawk. It is also very unfair. It is unfair to potential buyers and current owners who don't know what really happened in any given accident. Owners wonder if they should keep flying and potential buyers hold off until the facts are known.
It is also highly unfair to the manufacturer. Long delays in accident reports mean they have to suffer the effect of every half baked theory put out in the blogosphere based usually on hearsay coupled with little or no engineering knowledge.
If it turns out that there is a factory problem long delays in accident reports mean it takes longer before the problem is addressed. Again unfair to both customer and manufacturer.
