An agency that receives transferred aircraft parts must:
(a) Verify that all applicable labels and tags and historical and modification records accompany all serviceable aircraft parts (i.e., parts that are intended for flight use) that you receive. This requirement does not apply to parts for ground use only. See the tables in §102-33.370.
(b) Mutilate all transferred parts that you discover to be unsalvageable, and dispose of them properly, following the procedures in §102-33.315.
