Your brother's CASA must have been too heavy for the airport temperature and altitude on that particular day. That is a performance calculation problem. It is not the fault of the aircraft.
There are many factors which can limit the performance of an aircraft. (overloaded, too hot, too high, improper Center of Gravity, etc) Some of these factors could be at play with this ATR-72 crash as well.
One of the most difficult things a pilot trains for is an engine failure right at liftoff. Some pilots are better than others at this maneuver.
The investigation may prove otherwise but my gut feeling tells me the pilot did not handle the aircraft properly following an engine failure.
