In just one week after the incident, AAIB determined and published:
- What happened (inboard and outboard engine cowls on both engines detached, causing damage including loss of hydraulics and right engine fire)
- Where it happened (on the runway during take-off run)
- Why it happened (fan cowl doors were left unlatched)
- When the mistake was made (during a maintenance check the previous night)
- Who made mistakes (the maintenance crew for failing to follow published procedures; the flight crew for failing to adequately perform exterior checks)
They described the history of similar incidents in the past, and even managed to find photographic evidence of the unlatched engine cowls on the accident aircraft taken prior to pushback.
AND they issued a safety recommendation 2013-011 on visual checks to assure the position of the fan cowl door latches.
What more do you want, exactly?
