This incident was caused by spare parts storage protocols prior to issuance
to mechanics. The supervisor would gather the chip detectors & O-Rings,
assemble them as individual components that were kept in the supervisors
desk until needed. In this instance the supervisor failed to put the O-Rings
on the chip detectors. The mechanic installed the chip detectors as he found
them in the supervisors desk without O-Rings.

Would this be (also) an error on the mechanic's part (failing to check
or notice) or is this something that is not evident to the mechanic who
installs the part?
