Narrative:
During the phase inspection; the inspector made the following write-up: 'lowest decompression panel latch-coil spring and hinge pins not secured; flight deck door enhanced.' I removed a svcable latch off of a svcable door and installed it on the existing flight deck door. I subsequently learned the manufacturer of the door does not consider the latch to be a line replaceable unit. The aircraft was stopped and a new door assembly is being installed.
