41 CFR 102-36.180: -36.180 Excess Flight Safety Critical Aircraft Parts (FSCAP) disposal.

You may dispose of excess FSCAP if you determine that adequate documentation is available to allow transfer, donation, or sale of the part in accordance with part 102-33 of this subchapter. Otherwise, you must mutilate undocumented FSCAP that has no traceability to its original equipment manufacturer and dispose of it as scrap. When reporting excess FSCAP, annotate the manufacturer, date of manufacture, part number, serial number, and the appropriate Criticality Code on the SF 120. Ensure all available historical and maintenance records accompany the part at the time of issue.
