My point on timeliness is this:
* In some intances reporting of an accident can be a matter of 'life or death' (beyond whatever has been suffered as a direct result of the accident) for other pilots that might encounter similar circumstances - whether they be conditions, state of the a/c, pilot judgement, or whatever.
* Waiting for a full investigation followed by a quasi-inquest, then reporting, can sometimes mean a year or more of delay in getting vital information out.
* The investigating agency should be bound, in normal circumstances, to issue an "interim finding" as soon as the basic facts and circumstances are understood This could be qualified as necessary, if for instance exhaustive metallurgy and static loading tests on components are required. This qualification might say something like: "The port-side wing appears to have folded upwards at 90o from its normal orientation, at a point about 900mm in from the wing tip, prior to impact. Tests will be carried out in an attempt to ascertain the cause of this failure."
* This and other known information could act as a guide to other pilots / owners to check for any problem in the area in question (on type).
