Lessons Learned - Control of Temporary Installations (Wire Harness Fit Check)
Year: 1998
Abstract: Description of Driving Event:
A wire harness was installed on a flight unit for a fit check. Subsequent manufacturing operations were continued through several steps until it was realized that the wire harness was meant to be a temporary installation only. Production time was lost to back out and remove the harness so that it could be returned to its manufacturer to complete its detail manufacturing sequence and final test. This incident caused a slight impact (delay) to subcontractor's internal schedule, but had no effect on overall Program schedule.
Root cause: During the Manufacturing process it is very important to flag and control "temporary installations" to avoid wasting time or, in the worst case, building in sub-assemblies that are incomplete and/or untested.
