Often times this is done to preserve the evidence and wreckage associated with a crash and in the instances where criminal investigations and evidence are pursued, these chains of command are useful in dealing with the implications surrounding the criminal acts.
A press room and actions involving journalists also take place in this headquarters area. After a crash is investigated, the NTSB prepares statements from witnesses or other pertinent parties in order to formulate a final report (NTSB, 2002). This final report is the synthesis of the entire investigation and includes a "probable cause" as well as detailed information surrounding the circumstances of the crash (NTSB, 2002). The NTSB and the FAA often make recommendations and even policy and regulatory changes after a final report is issued and inferences can be made about causes of the crash.
Recent Crash Investigation and Analysis
The recent air crash in Alaska involving former U.S. Senator Ted Stevens was investigated by the NTSB, just as any air crash involving U.S. aircraft would be. But since the aircraft on which Mr. Stevens and other passengers were flying on was a privately-operated aircraft, it was not carrying either a flight data recorder or a cockpit voice recorder (Voice of America, 2010). This crash, like many other small aircraft crashes in the U.S., represent a challenge to investigators in that they are not able to use such tools to help determine probable cause and reconstruct the moments leading up to the crash itself. This is a major disadvantage in the investigation, but since this crash, like so many others, involved a celebrity, the NTSB was careful to conduct a thorough and discreet investigation.
The aircraft involved in the crash came down in a fairly remote section of Alaska, so access to the crash was very limited (Voice of America, 2010). This hampered NTSB efforts to create a headquarters of operation near the crash itself. Instead, investigators moved much of the crash from the point of impact to a hangar where they could more accurately understand the dynamics and specific circumstances that fed into the crash. Another major help to investigators was the fact that there were survivors who could help to relay the last moments of the crash in order for the NTSB staff to gain insight into exactly what happened, and to help establish probable cause (Voice of America, 2010). The NTSB was able to use reports from other pilots as well as official weather records and reports to help reconstruct the circumstances that could have potentially led up to the crash. They also interviewed other Alaska bush pilots and people who knew more about the experience levels of the pilots involved in the Stevens crash to help understand the human limitations associated with the incident (Voice of America, 2010).
After nearly a month of investigation and analysis, the NTSB was able to establish probable cause for the crash as a combination of pilot error and bad weather (Voice of America, 2010). Establishing this was not done through the typical methods of analysis like many other air crashes, but the NTSB was able to use its discretion in investigating, just as its own field manual spells out, and help to mold the investigation to the specifics of the crash itself, which was somewhat...
When an airplane catches on fire and jet fuel is the catalyst, the amount of time that the plane and the object around it will burn is dependent on many different factors. One of the primary factors is the amount of fuel that is still contained on the plane. For instance a jet that is taking a transatlantic flight will have more jet fuel than a regional flight. Investigators
U.S. statistics indicate that 80% of aviation accidents are due to human errors with 50% due to maintenance human factor problems. Current human factor management programs have not succeeded to the degree desired. Many industries today use performance excellence frameworks such as the Baldrige National Quality Award framework to improve over-all organizational effectiveness, organizational culture and personal learning and growth. A survey administered to a sample population of senior aviation
Unless the already low accident rate in aviation is reduced even further, the increased traffic volume will lead to an average of 25 accidents per year, with over 1,000 fatalities. Because 70% to 80% of all aviation accidents are considered to involve human error, one promising avenue appears to be investments in a better understanding of, and better support for, human performance and human-machine interaction. This includes improved system
.. I think he's passed off to our right." Later, the first officer is heard asking, "Are we clear of that Cessna?" The flight engineer responds with, "Supposed to be"; and the captain says, "I guess." ("CVR Transcript..." n.d.). The Accident The National Transportation Safety Board (NTSB) investigation report, referring to eyewitness accounts records that both aircrafts were proceeding in an easterly direction before the collision.

These were confirmed by the changes in the longitudinal (0.20 to 0.14 G), lateral (0.05 G. To the left) and normal load factors (1.0 to 0.6 G).
