Abstract
An extraction apparatus (40) for the removal of a riveted fastener (12) from a structure (10) includes a shaft (42) and a cutting element (62). The cutting element (62) is mechanically coupled to the shaft (42) and is configured to cut a portion of the riveted fastener (12). The shaft (42) and the cutting element (62) are configured for insertion through an inner channel (24) of the riveted fastener (12). A method of replacing the riveted fastener (12) from the structure (10) includes inserting the extraction apparatus (40) through the inner channel (24). The extraction apparatus (40) is rotated. A portion of the riveted fastener (12) that extends through the structure (10) is removed. A head (20) of the riveted fastener (12) is also removed from the structure.
