Methods for aircraft component repair and reclamation are provided. Cold spraying aircraft panels include identifying a fastener hole in an aircraft panel in need of repair, capturing the location of the fastener hole, and depositing cold spray material about the fastener hole for reclaiming the aircraft panel. Any excess material may be removed. Cold spraying hydraulic lines includes identifying a surface of the hydraulic line in need of repair, aiming a cold spray nozzle at the surface of the hydraulic line and depositing a cold spray material on the surface of the hydraulic line. Excess cold spray material may be removed as needed.
