A survey of Army aircraft structural failures caused by corrosion, Fatigue, and abrasion was made to define critical areas of future structural research. The primary source of data was the Army failure reports, 'Equipment Improvement Recommendation'. Because of the great number of reports available, a sampling was made consisting of basic airframe failures on four helicopters and two fixed-wing aircraft for the period 1 January 1963 to 31 August 1963. The reports were analyzed individually, and the data were consolidated. Analysis of all data revealed four significant problem areas: (1) corrosion and fatigue of primary airframe structure; (2) separation of metal bonded joints on rotor blades; (3) erosion of rotor blade leading edges; and (4) sustaining rotor blade balance.
