Abstract : This paper describes a test and evaluation program on the F-14 arresting gear hook shank. The objective was to develop criteria based on analysis and test results, whereby the proof load/inspection interval and overall service life of the hook shank could be safely extended. Fracture mechanics techniques provided a method of assessing the significance of proof tests and correlating proof loads with remaining life under operating loads. The results of this program showed that a two-phase proof load (axial followed by bending) could extend the proof-test interval from 100 to 125 arrested landing cycles. In addition, the total service life could be extended from 1000 to an indeterminate number of arrestments. (Author)
