Fastener removal apparatuses and methods of removing a fastener from a structure

A method for removing a fastener from a structure comprising:

• positioning a cutter cavity of a fastener removal apparatus adjacent a fastening collar secured to a pin of a fastener in a bore of a structure, wherein the fastener removal apparatus comprises
• a cutter comprising
• a first cutter end,
• a second cutter end, wherein a longitudinal axis is defined between the first cutter end and the second cutter end,
• an elongated cutter portion extending from the first cutter end to the second cutter end, wherein the elongated cutter portion comprises inner cutter walls defining a cutter cavity, and
• a cutting portion disposed on the second cutter end;
• and
• a guide disposed in the cutter cavity;
• after the positioning, forcibly contacting the cutting portion with the fastening collar and rotating the cutting portion, thereby reducing a first diameter of the fastening collar to no greater than a second diameter of the bore;
• and
• urging the pin through the bore of the structure, thereby removing the fastener from the structure.
