Accident Investigation :: Essays Papers

Accident Investigation Aircraft Investigation Each mishap has their own characteristics and there is no substitute for good old-fashioned common sense and initiative. Each wrecked aircraft has it’s own story to tell if properly investigated. However Air Force guidelines are quick to point out that investigators in their eagerness seek out the causes, often ignore safe investigation practices and common safety precautions. Air Force Investigators are maybe in even more difficult position due to the hazards that are unique to the military war fighting machines, I’ll discuss a few of these hazards briefly before I get into the steps of Air Force accident investigations. Munitions Extreme care must be given to the munitions that may have been on board the aircraft. Just because the ammunition appears to be damaged beyond being dangerous the slightest amount of static electricity from clothing may detonate munitions. Before starting an investigation of any kind, obtain the list of munitions aboard and have the explosive ordinance disposal (EOD) team remove or inert them. Again eagerness must be controlled and situational awareness must be exercised to be on the lookout for those munitions that may not have been recovered. Also, though tedious, the locations of all munitions need to be noted, as they will hold clues as well. The ejection seats can also present extreme dangers to untrained and careless investigator. Toxins Hydrazine. It’s a word that strikes fear in all that are familiar with it. New generation aircraft such as the F-16 use hydrazine for emergency power supplies. It looks like a clear oily substance that smells like ammonia. Some of the effects hydrazine can have on the human body include: liver damage, blindness, skin burns, and prolong exposure may be fatal. Only base bioenvironmental engineers are qualified enough to properly handle it. Materials Also somewhat unique but is gradually finding its way into the commercial side of aviation is the use of high composite materials along with exotic metals used in the effort to not only strengthen, but to lighten the overall weight of the airframe. The composites used with most frequency today are boron, graphite and Kevlar. Each of these materials has their own characteristics and must be handled with care. While in its finished form Kevlar is very stable, boron and graphite must be handled with extreme care to avoid breathing in dust created when the structures become damaged. Boron fibers can pierce through skin and stay imbedded indefinitely and cannot be removed easily causing severe infections.
