Narrative:
A major electrical system failure during a runway 16 ILS approach distracted the pilot. The Jetstar descended into a heavily wooded area, 6000 feet from the approach end of the runway.
Following a recent modification of the generator control circuitry, the aircraft's electrical system had experienced several multiple generator failures.

PROBABLE CAUSE: "A distraction of the pilot at a critical time as a result of a major electrical system malfunction which in combination with the adverse weather environment caused an undetected deviation of the aircraft's flightpath into the terrain."
