The airplane was not equipped with terrain avoidance warning system as is required by Federal Aviation Administration regulations. While it was removed by the previous owner of the plane, it’s not entirely clear why the TAWS application was not present. In any event, the accident pilot never contacted the tower over concerns that there was little room to maneuver to avoid mountains when a landing at the Phoenix airport was delayed. The airplane was also being flown on a moonless night.
Because the consequences of such a crash can be so severe, individuals that are responsible for failures of the plane to operate properly will need to be held responsible. Attorneys experienced in investigating such crashes often can make a determination as to what parties are responsible.
The cause of the airplane crashes requires detailed investigations. As the above accident demonstrates, it can be months or even years before determinations as to the cause of a crash can be made. Attorneys with access to the needed resources can in some cases expedite these investigations. However, attorneys will also need prior experience in trying these cases and be familiar with FAA and local regulations.
