Fatal Plane Accident

A study released by Boeing found that 48 percent of all fatal accidents worldwide between 2007 and 2016 occurred while the plane descended toward landing.

Although descent and landing processes represent only five percent of all flights, this moment is said to be the most dangerous time in commercial flight.

The second most dangerous flight stage is during takeoff and initial ascent. Even though it was only responsible for 13 percent of the incidents, it was during that phase that the plane was traveling rapidly near ground crew, other aircraft, and was upwind.

There are a lot of maneuvers that need to be done to get the aircraft to cruising altitude. Small mistakes can cause serious damage.

During takeoff and landing, there are a number of common causes of accidents. First, collisions with ground crews or vehicles not allowed to cross the runway.

Second, bad weather conditions can make it more difficult for pilots to control speed or maintain the plane's altitude when close to the ground.

Third, an aircraft crash can occur during taxiing or driving on the track, from poor visibility while descending, or if two aircraft are directed to the same runway during takeoff and landing.

On the other hand, there are a number of parties who can be held responsible for an accident, namely pilots, aircraft manufacturers, mechanics or maintenance crews, and traffic controllers.
