Aviation injury

Under the aviation injury understand the complex damage caused by external or internal parts of the aircraft during its operation in flight or on the ground, explosion and ignition of a combustible.
Damage generated in aviation disasters, have their own characteristics. Modern turboprop and jet aircraft are moving with great speed, high ceiling flight and have considerable capacity (both on-Board room for up to 300 passengers and sometimes more).
In the main causes of fatal accidents are technical problems with the aircraft, adverse weather conditions during the flight, during takeoff and landing of aircraft.
During disasters during the takeoff or landing arise shock load, leading to the spreading of fuel and ignited.
If in the period of the flight at high altitude (more than 8 thousand meters) occurs emergency depressurization, the crew members and passengers experiencing the phenomenon of barotrauma, morphological signs of which can be subsequently discovered during examination of the corpses.
When accidents it is necessary to solve complex issues, among which the main ones are: the establishment of working crew actions to establish the cause of death of the crew and passengers, and also play their poses. At the moment of collision of air transport with an obstacle body of persons on Board, overload brake, so that they move in the direction of motion and hit located ahead items fittings and interior. On clothing, shoes, body formed damage type "Stans-brands" specific localization. The nature and location of the damaged (torn clothing, shoes, bruises, scratches, wounds, fractures and others) due to the direction and magnitude of an overload, an anchoring system and pose passengers and crew. Even with heavy aviation disasters dead bodies remain completely, and 1/3 of cases are dismemberment in one way or another. While the bodies of the crew members are split up more often. At the same time, the thermal destruction of crew members are logged in twice less than passengers, as fuel bottle structurally situated in the middle part of the fuselage. "Burn shock" as a cause of death is registered in 16% of cases among the passengers and two times less - among the crew. The most frequent cause of death are multiple mechanical damage to the body, is incompatible with life.

damage to the propeller aircraft
Fig. 46. Damage to the propeller of a plane.

Extensive trauma of the body occurs under influence of blades of aircraft (Fig. 46) or by ingestion of a human body in a turbine jet engine.
When you hit the air ship in fixed seat belts crew members and passengers occurs trauma of the spine of the lumbar and cervical.
When it hits the air ship at an angle of 30 degrees or greater is the greatest displacement of the bodies of the passengers and crew relative to their initial positions and the greater their destruction. When confronted with the angle of 10 degrees and less dismemberment of bodies is not observed.
If the dead are in relative security, forensic expert produces external examination and subsequent autopsy and a description of the damage. When possible, is made a verbal portrait. In case of presence of the remains of the corpse explore and describe the size of its separate parts of their topographic identity, the nature of the damage, various imposing on them, intruded foreign body etc. it is Necessary to pay attention to special features, features of a structure of teeth, prosthetics, the scars, the traces of previously deferred surgical operations and other elaborate clothing or its remaining part (often during the fall and when you hit the ground clothes completely or partially out of the body). Register discovered documents, valuables, jewelry and other
It should be borne in mind that each crew member is in the cabin certain place, having before him the instruments, equipment, typical for each type of aircraft. Prints them on the body that occur during impact, help in some cases to decide on the location of each crew member, in the moment of the catastrophe.
The introduction of biological macro - and micro-particles in the part of management and other equipment cabins shows direct contact damaged parts of the body with the specific subject. On the other hand, it is possible introduction of microparticles fittings and interior (micro particles, paint, glass, plastic and other) in the clothes and the body.
Special attention is paid to investigation bodies of the crew members on the availability of carboxyhemoglobin (in the case of fire on Board the aircraft), drugs, narcotics, poisons, ethyl alcohol, pathological changes in the internal organs, as well as on the possible presence of the body gunshot injuries and stab wounds and other specific characteristics of violence.
Particular difficulties arise in the identification of persons, perished during accidents, and especially in determining the origin of parts one and the same corpse. This question is determined by generally accepted rules, and in case of aircraft accidents consideration is the responsibility of highly qualified specialists.
The examination of the scene, bodies and parts thereof, in a plane crash is of particular complexity and is normally conducted by a team of experts led by the most experienced expert. Fix the dead bodies and their parts in relation to the aircraft and its separate parts, state service, specific smells. Assign the individual parts of the body, thus to each part of the corpse attach tag serial number (or name, if known). Pay special attention to damage found the crew, prints parts of the control devices on the body and clothing (gloves, shoes), possible signs of gunshot injuries, poisoning by carbon monoxide, etc.
