In this statistical review of 1467 Army helicopter accidents occurring between July 1957 and December 1961, pilot factors are significantly consistent, having been reported in 72% of all accidents. Pilot factors alone in these accidents have been responsible for 28% of all accidents. Accidents of this category occurred at a rate of 13.2/100,000 hours flown in 1958-1959 and increased to the rate of 22.9/100,000 hours during the 1960-1961 period. In contrast within this same time frame the overall accident rate decreased 1.0/100,000 hours. Fifteen pilot factors that show a frequency increase have been identified with the increase of 117 pilot-caused accidents of the 1960-1961 period. Six factors in the order listed below reflected the greatest increase in frequency: (1) Improper use of light controls; (2) Misjudged distance, altitude or position; (3) Improper level off; (4) Failure to see aircraft or object; (5) Misuse of power plant controls; (6) Failed to maintain flying speed.
