This essay focuses on better understanding what caused the Japan airlines flight 123 incident, that happend on the way from Tokyo to Osaka and was registered as ja8119. This essay describes the mechanical problem, which occurred within the engines, that caused vibrations in the flight, primary flight controls functions, human error factors and secondary mechanical factors.
In this essay, the accident was said to have been caused by loss of primary flight controls functions. This means that the flight control functions were fault bringing in a mechanical problem on the airplane operation. This implies that the engines and the flight control functions were the two major primary source factors contributing to the incidents. Also this essay describes secondary mechanical factors, which developed many complications throughout the investigation. One of the main secondary factors discussed in this essay was the structure of the aft pressures bulkhead, that was designed in a manner that it could not allow pressure to be released and built up effectively in the plane. As a result, more pressure developed in it, the crack connectivity of rivet to rivet also might eventually lead to destruction of the plane. Evidences, presented in this essay also suggest that ineffectively sized wings flaps were installed on the plane before departure.
In conclusion, this essay provides the reader greatly researched investigation of what might cause the damage of a plane. Good explanation and clear structure makes this essay easy to read and understand.
