What will probably come out of the investigation having read the initial report is that
The AOC holder was appropriately licensed in ICAO/EU /National requirements
The ticket agency was approprately licensed and operating within their legal requirements.
The aircraft was 'serviceable' with no significant defects.
The crew were appropriately licensed, 'current', and in hours to do the flight.
Corks ATC service and infrastructure were all licensed appropriately and equipment serviceable.
The initial report indicates crew training, AOC requirements etc will be covered within the 'full' investigation as is normal procedure. At this stage the major cause would appear to be the failure to adhere to approach minima requirements. The investigation may or may not determine if that was a regular occurance or culture within the organisations/individuals involved throughout the accident.
