whatever the cause and circumstances, the 'official' report will probably hold the interior aviation authority and local politics blameless and blame apportioned to the nationility of the pilot, the age of the aircraft, the country of manufacture of the aircraft etc etc.
result.. introduce an additional medical for non-national pilots, and ban aircraft over 10 years old and 'prevention' of a repeat incident is done. and no, this is not a generalisation, but an assessment predicated on historical events.
me ? i'll wait for any NTSB data (US manufactured aircraft) before speculating on cause and circumstance.
