I doubt very much that this was the same problem, otherwise the aircraft could not have flown from Isla Margarita to Puerto Ordaz without any obvious control problems.

More likely, the problem was just one more case of the reversal of flight control forces on ATR's operating in heavy icing conditions, like the most recent crash of the Cuban airline Aerocaribbean, which occurred about six weeks after this last accident in Venezuela. Follow this link:

It's not rocket science.
By the way, before you ask the question, heavy icing is not unusual in the tropics at turbo-prop cruise altitudes, around 20K'.
