The purpose of air crash investigations is to determine the reasons for accident and make safety recommendations to avoid recurrences and if possible preserve life. Its aim is not to apportion blame and liability if any on an individual or organization. Safety Boards are assigned the mandate to carry out these investigations. however, these are not regulatory bodies since approval and implementation of regulation is within the domain of Federal Aviation Authority (FAA) and Civil Aviation Authority (CAA). According to Boeing (2010), majority of the aircraft accidents were causes by pilot or flight crew error indicating a high percentage of human factor, followed by defective equipment or component that made up 14% of the total while less than one-third the human factor as shown in figure below: Figure 1 : Percentage of Causes for Air Accidents 2.0 Description of the Accident Continental Express Flight 2574, a domestic flight, was scheduled from Laredo International Airport in Laredo, Texas to Bush Intercontinental Airport in Houston, Texas on 11 September 1991 with 12 passengers and two crew members on board.
