In the analysis of accidents a collision between aircraft is treated as one accident in the overall total. However, a complete analysis and coding is made on each aircraft involved in a collision. This produces two aircraft accident records, one for each aircraft. These records contain the same broad categories of coded data, however, the specific entries, such as type of aircraft, kind of flying, phase of operation, etc., may or may not be common to each aircraft. As a result, the number of accidents may differ in the various tables depending upon whether or not collisions are involved and if so, whether or not the selected itsms of data are common to each aircraft. Included in the total number of accidents are 63 collisions between aircraft. By coding each aircraft involved in the collisions an additional 63 records are produced, bringing the total accident records to 5,031. This figure reflects the true number of pilots and aircraft involved in the 4,968 accidents. (Author)
