This is from the NTSB web-site:
Safety Recommendations
Safety recommendations are the most important part of the Safety Board's mandate. The Board must address safety deficiencies immediately, and therefore often issues recommendations before the completion of investigations. Recommendations are based on findings of the investigation, and may address deficiencies that do not pertain directly to what is ultimately determined to be the cause of the accident.
For example, in the course of its investigation of the crash of TWA flight 800, once it was determined that an explosion in the center fuel tank caused the breakup of the aircraft, the Board issued an urgent safety recommendation and three other recommendations in 1996, four years before completion of its investigation, that were aimed at eliminating explosive fuel/air vapors in airliner fuel tanks. The Board issued an additional recommendation in 1997 regarding the detection of explosives and six recommendations in 1998 to improve fuel quantity indication systems. When the Board issued its final report on the TWA 800 accident in 2000, four additional safety recommendations were issued that focused on the aircraft wiring systems.
Why on earth is the ATSB drifting off from the rest of the world? Imagine if there was ever a large fatal here (touch wood), these clowns wouldn't have a clue.
